Komatsu PC30MR-1-K(S/N 10001-UP)
Maintenance schedule, common problems & OEM parts breakdown
The Komatsu PC30MR-1-K (S/N 10001-UP) is a sub-3-tonne, zero-tail-swing (Minimum Radius) hydraulic mini excavator built for confined-site digging, utility trenching, and light landscaping work. It is powered by Komatsu's 3D84E-3K, a naturally aspirated, mechanically governed 3-cylinder diesel of roughly 1.5 L displacement producing about 20.6 kW (roughly 27-28 PS) at 2,500 rpm - a pre-emissions-era engine with a jerk-pump/governor fuel system and no electronic control unit or KOMTRAX telematics. Factory and parts-catalog figures place its operating weight in the roughly 2,930-3,200 kg band, varying with canopy-versus-cab superstructure and rubber-versus-steel track shoes (steel-shoe, cab-equipped units run toward the top of that range). Marketed under Komatsu Utility Corporation branding, the -1-K entered the lineup around 1998, following the PC30-7 and PC30R generation of compact excavators, and was offered with an open two-post ROPS canopy or an enclosed ROPS cab, rubber or steel crawler shoes, and an optional angling dozer blade.
The next real engineering break in the family came with the PC30MR-2 GALEO update in the low-to-mid 2000s, when Komatsu swapped in the larger 3D88E-family engine, added KOMTRAX remote monitoring and a closed-center load-sensing hydraulic circuit, and pushed operating weight up into the roughly 3,140-3,465 kg range - none of which apply to the earlier, mechanically simpler -1-K. That simplicity is exactly why the PC30MR-1-K still holds a place in the used and parts market today: its non-electronic 3D84E-3K engine and conventional gear-pump hydraulics are comparatively easy to diagnose and rebuild without dealer scan tools, making surviving units attractive to owner-operators, landscapers, and rental fleets that want a zero-tail-swing footprint without telematics-era cost or complexity. Parts support also benefits from commonality with sibling Komatsu compact excavators of the same era, keeping ownership costs manageable even as original factory documentation grows scarcer.

| Emissions tier | Not documented in available sources; this is a 1990s-era (KUC-spec, S/N 10001-Up, first sales circa 1998) mechanical diesel predating modern EPA/EU emissions tiers - no tier certification found |
| Contamination note | Some aggregator/search summaries attach a Komatsu 3D88E-6/3D88E-7 engine (28.7-29.5 hp) and ~3,140-3,290 kg weight class to the 'PC30MR-1' name; those figures match the later PC30MR-2/PC30MR-3 generations, not this S/N 10001-Up unit, and were excluded here |
Weights
| Operating weight (verified listing) | approx. 2,930 kg (6,460 lb) - transcribed from an actual PC30MR-1 machine listing |
| Operating weight (secondary/disputed figure) | Some generic 'PC30MR' family spec sheets cite approx. 3,140 kg (6,922 lb); this appears in sources also citing the 3D88E engine, indicating likely conflation with a later PC30MR generation - treat as unverified for this specific S/N range |
| Ground pressure | approx. 0.30 kg/cm2 (approx. 29.4 kPa / 4.3 psi), per general PC30MR family literature - not independently confirmed as serial-specific |
| Transport weight | Not found as distinct from operating weight in available sources (typical for this weight class of mini excavator) |
Dimensions
| Overall transport length | approx. 4,390 mm (14 ft 5 in), per verified machine listing |

| Gradeability | approx. 30 degrees (58%) - family-level source |
| Max drawbar/traction force | approx. 3,400 kgf (approx. 33.3 kN) - family-level source |
| Max dig depth / max reach / max dump height / max cutting height | Not reliably verified for this specific PC30MR-1 (S/N 10001-Up) unit - figures found online (e.g., approx. 2,760 mm dig depth, approx. 4,910 mm reach) are tied to sources that reference the 3D88E engine and are more likely PC30MR-2/PC30MR-3 data; excluded here to avoid cross-model contamination |
Forces
| Bucket digging force (ISO) | approx. 3,000 kgf (approx. 29.4 kN) - cross-referenced in two independent search summaries tied to the PC30MR-1 designation, though exact serial-specific confirmation was not located |
| Arm/stick crowd digging force (ISO) | approx. 1,800 kgf (approx. 17.7 kN) - single-source reference, not independently cross-verified; treat as indicative |
| Std vs long stick variation | No source distinguished standard vs. long-stick arm force values for this model - only one arm length configuration was found referenced (approx. 1.27 m / 4 ft 2 in stick) |

PC30MR-1-K(S/N 10001-UP) fluids & capacities
| System | Capacity | Recommended fluid |
|---|---|---|
| Engine crankcase (with filter) | approx. 7.2 L (1.9 US gal); exact PC30MR-1-K OMM figure not independently located, value cross-referenced from the closely related same-class PC30MR-2 generation and typical for the Komatsu 3D84E-family engine used on this machine | Komatsu Genuine diesel engine oil EO10W30-DH (API CI-4/CD, JASO DH-1) for roughly -20 to 40C ambient, or EO15W40-DH for -15 to 50C; this pre-DPF era engine uses standard Komatsu EO-DH oil, not the later Low-Ash (LA/ULA) grades reserved for Tier 4 engines |
| Cooling system | approx. 3.3 L (0.87 US gal); consistent across PC30MR-2 and PC30MR-5 OMM data, treated as representative for the PC30MR-1 generation of similar displacement/radiator size | Komatsu Genuine Super Coolant AF-NAC - non-amine, non-nitrite ethylene-glycol antifreeze/anti-corrosion coolant, rated for roughly -30 to 50C ambient use, with a 2-year/4,000-hour service life; dilute per the OMM's antifreeze-percentage-vs-minimum-temperature table for the local climate |
| Fuel tank | approx. 41-44 L (10.8-11.6 US gal) - figures vary by generation/source (PC30MR-2 listed at ~44 L, PC30MR-5 at ~41 L); treat as varies by configuration/series for the PC30MR-1 | Diesel fuel meeting ASTM D975 No. 2-D or EN 590 Class 2 (low-sulfur); switch to a winter-grade/cold-flow-improved blend below about -20C to avoid fuel waxing |
| Hydraulic system total | approx. 40 L (10.6 US gal) total system refill, per older-generation PC30MR/PC30MR-2 sourcing; note this figure varies by configuration/series and could not be confirmed specifically for the PC30MR-1-K | Komatsu Genuine hydraulic oil HO46-HM (ISO VG46, DIN 51524 Part 2 class HLP) for roughly -10 to 50C ambient, or HO56-HE (SAE 5W-30 multigrade) for wider -20 to 50C climate range; Komatsu Genuine BIO hydraulic oil is also offered as an environmentally friendly synthetic-ester alternative |
| Hydraulic tank | approx. 20 L (5.3 US gal) reported for a redesigned later PC30MR-5-era tank; older PC30MR-1/-2-era tank capacity not independently confirmed - varies by configuration/series | Same as hydraulic system total: Komatsu Genuine HO46-HM or HO56-HE hydraulic oil |
| Final drive (each) | not published in any public source located for this exact model/serial range despite extensive searching; small (~3 ton class) Komatsu mini-excavator final drives of this era typically hold only a small (roughly 1-2 L) gear-case fill if a distinct oil change point exists at all | Where the OMM specifies a final-drive oil change point: Komatsu Genuine powertrain oil TO30 (SAE 30W, API CD) for warmer climates or TO10 (SAE 10W, API CD) for cold climates, per the ambient-temperature selection chart |
| Swing drive | not published in any public source located for this exact model/serial range; on this size class the swing (slewing) drive reduction gear either shares hydraulic system oil or uses a small dedicated gear-case fill not separately documented online | Where a dedicated swing-machinery gear case is specified: Komatsu Genuine powertrain oil TO30/TO10 (as above); where the swing motor/reduction unit is hydraulic-oil lubricated, use the same HO46-HM/HO56-HE hydraulic oil as the main system |
| Grease (spec only) | no reservoir capacity - applied at lubrication points per the OMM's periodic lubrication chart, not a fill-and-measure system | Komatsu Genuine grease G2-LI (multipurpose lithium-based grease) for roughly -10 to 50C ambient, or G2-TE (extreme cold-weather grease) for roughly -20 to 50C ambient, applied per the lubrication-chart interval and point |
Capacities are refill values from factory literature — always fill to the dipstick/sight gauge, not the number.

Servicing the PC30MR-1-K(S/N 10001-UP) beyond the schedule
Predictive Maintenance & Fluid Analysis
On a mechanically governed 3D84E-3K with no ECU to flag drift, fluid sampling is the main early-warning tool. Pull engine oil samples at change intervals and watch for silicon from a bypassing air cleaner and for coolant intrusion, since the naturally aspirated three-cylinder has no turbocharger to mask a failing head gasket. Sample hydraulic tank oil for water and metal fines from the gear-type pump and Nachi travel motors, and track fuel filter and water-separator loading closely, since the mechanical injection pump tolerates contaminated diesel poorly.
Corrective & Common Repairs
Typical corrective work on the -1-K centers on the mechanical governor and injection pump linkage drifting out of adjustment, causing rough idle or power loss, and on worn travel and swing motor seals letting oil weep past the Nachi final drives. High-hour rubber crawler shoes crack or separate from the core, and boom, arm, and bucket pin-and-bushing wear opens up joint play. Because the machine predates KOMTRAX, diagnosis relies on manual pressure-gauge checks at the pump and relief valves rather than stored fault codes.
Overhaul & Rebuild Points
When rebuild time comes, focus on the 3D84E-3K's cylinder liners, injection pump, and valve train, since this naturally aspirated engine has no turbocharger to complicate a top-end job. On the hydraulic side, the gear pump, control valve spools, and Nachi 2-speed travel motors are the wear items worth bench-testing before committing to a full hydraulic rebuild. Undercarriage overhaul should evaluate sprockets, rollers, and idlers alongside the rubber or steel shoes together, since the zero-tail-swing frame geometry makes partial undercarriage replacement less cost-effective than a matched set.
Seasonal & Environment Servicing
Cold-weather starts are the main seasonal risk on the -1-K's mechanically governed diesel: use correctly rated low-temperature engine oil and diesel, and keep starting-aid circuits and the small-capacity cooling system in good order to avoid hard starting. In hot, dusty environments, check the compact radiator and oil cooler fins and the air cleaner element more often than the standard interval, since the naturally aspirated engine has little margin for airflow restriction. Inspect rubber tracks for heat-cracking in summer and for ice or debris packing around rollers and sprockets in winter.

PC30MR-1-K(S/N 10001-UP) fault codes & troubleshooting
| Code | Meaning | Likely cause | What to do |
|---|---|---|---|
| No CID/FMI or alphanumeric fault code display (mechanical engine, no ECU/KOMTRAX) | The PC30MR-1-K(S/N 10001-UP) is a late-1990s/early-2000s KUC-spec compact excavator built around the Komatsu 3D84E-family engine (3D84E-3K, a Yanmar 3TNE84-derived block), a mechanically governed, direct-injection diesel with a jerk-type injection pump and flyweight governor rather than an electronic engine control unit; it predates KOMTRAX and the digital monitor/fault-code systems used on later Komatsu excavators. | Not applicable - there is no engine controller or diagnostic module on this machine capable of generating numeric or alphanumeric fault codes. | Diagnose using the shop manual's mechanical troubleshooting tables (pressure gauges, multimeter, visual/lamp checks) rather than a code reader; do not apply E-code, CA-code, or CID/FMI lists published for later electronically controlled Komatsu excavators to this machine. |
| Engine oil pressure warning lamp (red oil-can symbol, monitor panel) | Engine lubrication pressure has dropped below the safe threshold. | Low engine oil level, clogged oil filter/strainer, worn oil pump, or a failed oil pressure sender/switch. | Stop the engine immediately, check oil level and condition, replace the filter, and verify the pressure switch before restarting. |
| Battery / charge warning lamp (red battery symbol, monitor panel) | The alternator is not charging the battery. | Broken or slipping alternator/fan belt, faulty alternator, or a loose/corroded wiring connection. | Check belt tension and condition first, then test alternator output and battery terminals. |
| Coolant (water) temperature warning lamp (red thermometer symbol, monitor panel) | Engine coolant temperature has exceeded the normal operating range (overheat). | Low coolant level, clogged radiator fins/core, slipping fan belt, faulty thermostat, or failed temperature sender. | Stop and idle the engine to cool down, check coolant level and radiator for debris, and inspect the fan belt before resuming work. |
| Air cleaner (clog) warning lamp, monitor panel | Air filter restriction has reached the point of reducing intake airflow to the engine. | Dust/debris-loaded air filter element or a collapsed/damaged element. | Clean or replace the air filter element and inspect the intake ducting for damage. |
| Glow/preheat indicator lamp (amber coil symbol, monitor panel) | Not a fault - indicates the intake air preheating (glow plug) circuit is active for cold starting; the mechanical 3D84E/3TNE84-family engine retains a glow-plug preheat aid despite being direct-injection, controlled by a simple timed relay rather than an engine ECU. | Normal cold-start operation; stays on briefly before cranking in low ambient temperatures. | Wait for the lamp to go out (or the specified preheat time to elapse) before cranking; if it never illuminates or stays on abnormally long, check the glow circuit fuse/relay and glow plugs. |
| Fuel level low warning (gauge/lamp, monitor panel) | Fuel tank level has dropped to a low reserve threshold. | Simple fuel depletion, or a faulty fuel level sender giving a false low reading. | Refuel; if the gauge misreads after refueling, check the sender unit and wiring. |
Codes and remedies are general guidance for this model family — always confirm with diagnostic tooling and your dealer before major repairs.
PC30MR-1-K(S/N 10001-UP) attachments & work tools
Buckets
The PC30MR-1-K (S/N 10001-UP) is a roughly 3.14 t operating-weight mini excavator whose reference GD (general-duty) bucket runs about 0.09 m³ SAE-heaped (0.12 yd³) / ~0.08 m³ CECE-heaped, with common width steps across this size class spanning roughly 300-650 mm (12-26 in). Buckets on this class are normally pin-on (mounted directly on the bucket pin); coupler use requires a hydraulic or mechanical quick coupler sized to match, since bucket pin diameter for this PC27/PC30/PC35 mini-excavator family is commonly cited around 35 mm.
Hydraulic hammers
Aftermarket breaker guides place this machine in the 2.5-3.8 t carrier bracket (the same class used for its ripper-tooth and grapple attachment options), matching compact/mini hammer lines from brands such as HydroRam, Rammer, NPK and Indeco. A class-matched breaker in this bracket typically runs about 150-200 kg working weight (e.g., a 2.5-3.8 t-class hammer near 175 kg) and needs roughly 25-45 L/min of auxiliary hydraulic flow, well below what larger 10+ t class breakers require.
Quick couplers
Steelwrist lists the PC30MR platform against its S-series hydraulic/mechanical couplers and lighter-duty XT tilt couplers (2-24 t) / X04 tiltrotator (2-4 t) as the class-appropriate options, though the S-series itself spans a much wider 0-70 t rating. Aftermarket mini-excavator quick hitches sized for the 2-4 t bracket commonly use 35-40 mm coupler pins, consistent with this machine's bucket pin size.
Thumbs/grapples
Weld-on and hydraulic thumb kits are marketed specifically for the ~3 t PC30MR bucket linkage, typically replacing the bucket pin with a thumb pivot and running a cylinder off the machine's auxiliary hydraulics. Mechanical grapples (3+2 and 4+3 finger, brush and rock-pattern styles) are also offered sized for the 2.9-3.8 t class that covers this machine's operating weight.
Rippers
A dedicated boom-mounted ripper shank is not a common attachment for this size class; instead, ripper-tooth/rock-tooth bucket attachments sized for 2.9-3.8 t excavators are the typical rock-working tool, fitted in place of a standard digging bucket rather than as a separate ripper arm.
Hydraulic-kit notes
Factory-level figures reported for this PC30MR generation show a hydraulic relief pressure near 265 bar (3,840 psi) and combined main pump flow near 89 L/min (23.5 gpm), but a verified dedicated auxiliary (breaker/thumb) circuit flow rating specific to the PC30MR-1-K was not found in available sources. Attachment circuits on this class typically need only about 25-45 L/min, so actual auxiliary-line flow should be confirmed on the machine before ordering a tool; figures vary by configuration/series (a later PC30MR-5 document cites roughly 50 L/min auxiliary flow at 20.5 MPa).

PC30MR-1-K(S/N 10001-UP) serial number reference
On the PC30MR-1-K, the PIN/serial number is on a small plate or Komatsu decal at the front of the machine, generally on or near the main revolving frame close to the boom mounting/foot-pin area. Not documented for this exact model—verify placement with the machine in hand or with a dealer. Engine and travel-motor serial plates are found separately. This vintage uses short numeric serial (10001-up) rather than 17-character VIN. KUC is the spec-code identifying the parts-manual grouping (shown as "PC30MR-1-K" or "PC30MR-1 (KUC Spec.)") for which the numeric serial falls. The KUC code is not stamped as a prefix on the serial-number line; match the plate's serial against the 10001-UP range to confirm KUC spec.

| KUC | PC30MR-1-K standard swing-boom mini excavator, S/N 10001-UP | KUC is the Komatsu spec code in the parts-manual title "PC30MR-1 S/N 10001-UP (KUC Spec.)". The model designation PC30MR-1-K uses K as shorthand for KUC spec grouping. Within the KUC/10001-UP run, a running change at approximately S/N 13815 shifted to a 2-way (2-spool) control-valve/main-pump configuration; this is a serial break within the range, not a separate 3-character prefix. Engine fitted: Komatsu 3-cylinder 3D84E-family diesel, with 3D84E-3K suffix for this model (also grouped with PC30UU-3). Exact suffix varies by related model (PC30R-8 uses 3D84E-3F; PC30-7 uses 3D84-3). Confirm exact engine suffix with dealer using the machine's own engine serial plate. No separate long-undercarriage (LC) or regional-plant prefix documented. |
Frequently asked questions
What engine does the Komatsu PC30MR-1-K (S/N 10001-UP) use?
It uses Komatsu's 3D84E-3K, a naturally aspirated, mechanically governed 3-cylinder diesel of about 1.5 L displacement producing roughly 20.6 kW (about 27-28 PS) at 2,500 rpm, with no electronic control unit or turbocharger. Later PC30MR generations (PC30MR-2 and beyond) switched to the larger 3D88E-family engine, so that engine does not apply to this early -1-K serial range.
What is the operating weight of the Komatsu PC30MR-1-K (S/N 10001-UP)?
Roughly 2,930-3,200 kg, varying with configuration: canopy versus enclosed cab and rubber versus steel track shoes shift the figure toward the higher end of that range. Treat any single exact number with caution, since published spec sheets vary by configuration and are sometimes mixed with later-series figures.
What replaced the Komatsu PC30MR-1-K?
Komatsu succeeded it with the PC30MR-2, part of the GALEO model generation introduced in the low-to-mid 2000s, which added KOMTRAX telematics, a closed-center load-sensing hydraulic system, and the larger, heavier 3D88E-family engine in place of the -1-K's 3D84E-3K.
What PC30MR-1-K(S/N 10001-UP) owners discuss
What do owners and technicians generally say about the Komatsu PC30MR-1-K (S/N 10001-UP) as a machine to own and operate?
Community sentiment on forums such as Heavy Equipment Forums is generally positive: the zero-tail-swing layout and enclosed cab are praised for letting the machine work close to walls, trenches, and other obstacles while giving the operator good all-round visibility and weather protection. Controls are described as intuitive and precise, similar to other Komatsu excavators of the era, so operators moving between models adapt quickly. The most consistent complaint across owner comments is not the base machine itself but wear items and age-related hydraulics (see below) - this generation is now decades old (circa-1998 KUC-spec production), so most surviving units have already been through at least one round of seal, hose, and undercarriage renewal.
Owners report the engine revs dip or the machine almost stalls every time hydraulic travel/function stops - what's the consensus cause?
This is one of the most frequently repeated complaints tied to this model on Heavy Equipment Forums. The pattern described is: revs are fine while a function is moving, then as soon as the lever returns to neutral the engine note drops and sounds like it's about to stall before recovering when movement resumes. Community consensus points to the closed-center load-sensing (LS) hydraulic system rather than the engine itself - the LS valve/cartridge in the pump maintains a slightly higher standby pressure than what the main control valve sees, and a worn seat or broken spring in that cartridge (or a fouled/faulty flow-sensor valve feeding pressure feedback to the pump) upsets that balance. Forum-quoted service-manual figures for LS differential pressure are roughly 32 bar (about 464 psi) with all levers in neutral and roughly 15.6 bar (about 227 psi) with the bucket curled under no load - technicians use these as a bench check when the cartridge is pulled and inspected. Have your dealer or a qualified hydraulics technician verify LS valve and pump pressures before condemning the pump.
Some owners describe the boom or upper structure as 'pushable' by hand, or losing swing power in one direction - what's typically going on?
Threads describing full range of motion but weak swing torque in one or both directions, boom drifting downhill on a slope, or the upper structure being movable by hand even with the engine off are usually traced to swing motor or swing brake wear rather than the swing gearbox itself - internal leakage across a worn swing motor lets the brake release under load without enough torque to hold position. Because the swing circuit on this class of machine shares supply with other functions through the same load-sensing pump, a weak swing symptom is sometimes actually a symptom of the broader LS/pump wear discussed above, so community advice is to isolate the swing circuit with a flow/pressure test before replacing the swing motor. Have your dealer or hydraulics specialist confirm swing motor and brake-release pressures before replacing the motor.
What undercarriage and wear-item patterns are typical for this machine, and what should an owner watch for?
As with other rubber-tracked mini excavators in this class, owner and parts-supplier commentary agrees that rubber track pads wear or chunk out faster on rough, rocky, or abrasive ground than on soil, and that bottom rollers, front idlers, and the track adjuster/tensioner are the next parts to need attention as hours accumulate. General mini-excavator inspection guidance (echoed across buyer/inspection write-ups, not manufacturer-specific to this serial range) is to check track sag at the midpoint between idler and sprocket - commonly cited as roughly 10-20 mm (about 0.4-0.8 in) of sag as a rough guide, though exact figures vary by track type and should be checked against the service manual. Track tensioners on this family use a grease-and-spring cartridge; a tensioner that won't take grease or won't hold tension is a commonly reported failure mode reported in the wider Komatsu mini-excavator community rather than specific complaints. Because this is a zero-tail-swing design, forum commentary also flags the swing/slew bearing as a higher-value wear item to check by hand for play before buying or during routine service.
Does the engine on this series have any known quirks, and does it change across PC30MR generations?
Community and parts-catalog sources confirm the PC30MR-1-K (S/N 10001-UP) of this era uses the Komatsu 3D84E engine family (3D84E-3K variant), a small naturally aspirated indirect-injection diesel shared across several Komatsu mini excavators and compact wheel loaders of the period. Because it predates electronic engine management, forum commentary about this specific generation centers on mechanical fuel-system and cold-start issues typical of engines of this vintage - fuel delivery problems traced to injection-pump plungers sticking from dirty/watered fuel, clogged fuel-inlet screens, and glow-plug circuits that should be checked individually if cold starting is hard. This is a mechanically-governed engine, so throttle-related complaints reported on some later PC30MR-5-generation forum threads (an electronically controlled throttle system) are a different-series issue and do not apply to this earlier PC30MR-1-K platform - a useful distinction to keep in mind when reading mixed-generation forum threads. Have your dealer verify fuel-system and glow-plug condition before assuming an injection-pump rebuild is needed.
What electrical or sensor issues come up most often in community discussions of this machine?
Because this generation predates the digital multi-code monitor panels used on later, larger Komatsu excavators, forum discussion of 'sensor' problems on this specific model centers on the hydraulic pressure/flow sensor feeding the pump's LS/EPC circuitry (see the stalling question above) rather than a network of electronic fault codes. Separately, pilot-valve and joystick complaints reported across the wider Komatsu mini-excavator community (not this serial range specifically) point to degraded o-rings inside the pilot control valve and worn joystick pilot-valve plungers as common causes of inconsistent or sticky function response; both are described as straightforward seal-kit fixes once isolated. General advice repeated across sources for any electrical gremlin on machines this age is to start with basics - battery/charging condition, connector corrosion, and chafed harness runs near the swing frame - before chasing sensors. Have your dealer or an experienced technician confirm which sensor or valve is at fault with a pressure gauge before replacing parts.
What should a buyer specifically check before purchasing a used PC30MR-1-K(S/N 10001-UP)?
Buyer and inspection-guide consensus (general mini-excavator practice plus this-model-specific forum threads) points to: (1) hydraulics first - cycle every function including simultaneous operation, watch for the rev-drop/stall symptom described above, check fluid clarity (should be clear amber, not dark or milky), and look for wet spots at cylinder rod seals and hose fittings; (2) the swing/slew bearing - with the engine off, try to rock the upper structure by hand for play, then run it through a full rotation listening for grinding or binding; (3) undercarriage - inspect rubber tracks for cuts, dry rot, and remaining lug height, check track sag, and confirm the track tensioner holds grease/pressure; (4) engine - given the age of this serial range, confirm cold starting behavior, glow plug function, and that there's no persistent white/blue smoke; (5) documented history - hour meter plausibility versus visible wear, service records, and, if possible, a hydraulic oil sample; note that Komatsu mini excavators of this generation are a mix of domestic and grey-market imports, so confirming the exact model/serial range against the dataplate matters for parts availability. Have your dealer or an independent inspector verify hydraulic pump/LS pressures, swing bearing play, and structural welds before finalizing a purchase.
