Komatsu PC38UU-2(S/N 3001-UP)
Maintenance schedule, common problems & OEM parts breakdown
The Komatsu PC38UU-2 (S/N 3001-UP) is a Japan-built mini hydraulic excavator in the roughly 3.5-3.8 tonne class (about 3,690 kg/8,136 lb in typical trim), sized for confined-space digging where a full-swing machine will not fit. It runs a Komatsu 3D84-2GA diesel: 3-cylinder, water-cooled, naturally aspirated, about 1.4 L displacement, mechanically governed with no electronic engine control, rated around 22.4 kW (30 hp) gross. The 3001-UP serial block covers one continuous production run of this generation, following the earlier PC38UU-1 (3D84-1 engine) and preceding the PC38UU-2E "Avance" cab variant, which carries its own separate model number and a larger 3D84E-3C engine. Komatsu offered the PC38UU-2 with a canopy or an enclosed cab, a rear backfill/dozer blade, standard or wide rubber track pads, and a factory hydraulic-thumb option alongside the standard pin-on bucket; its zero-tail-swing upper structure and two-piece offset boom, paired with dual-speed travel, let it dig and slew close to walls and trenches without swinging the counterweight past the tracks.
Across the PC38UU family the core layout carried through each update: three-cylinder Komatsu diesel, offset boom, zero-tail-swing upper structure. The -1 used the 3D84-1 engine; this -2 generation moved to the revised 3D84-2GA fuel system and governor; the parallel Avance/-2E line switched to the larger 3D84E-3C engine with a factory cab. Later PC38UU-3 and subsequent generations, up through today's PC38UU-6, added Tier-compliant engines and updated hydraulics, moving well past the mechanical, ECM-free simplicity of this generation. That simplicity keeps S/N 3001-UP machines active in the used and parts market today: nothing to fault-code, straightforward mechanical injection to service, and a wide installed base that keeps tracks, undercarriage, and driveline parts in aftermarket supply long after Komatsu moved this size class forward.

PC38UU-2(S/N 3001-UP) fluids & capacities
| System | Capacity | Recommended fluid |
|---|---|---|
| Engine crankcase (with filter) | Approx. 6.2 L (1.6 US gal) for the 3D84-2 series diesel, filter change included. This is an engine-family figure; confirm against the dipstick/nameplate for this exact chassis since a unit-specific pan capacity is not separately published. | Komatsu Genuine diesel engine oil (EO series). SAE 10W-30 for cold climates (roughly -20C to 40C ambient), SAE 15W-40 as an all-season grade (-15C to 50C), or straight SAE 30 in warm, steady climates. A quality API CD/CI-4 equivalent is acceptable where genuine Komatsu oil is unavailable. |
| Cooling system | Not documented for this exact serial range in available literature. Confirm against the radiator/reserve-tank fill mark or dealer parts data. | Komatsu Super Coolant AF-NAC, a long-life, non-amine, non-nitrite ethylene glycol antifreeze and anti-corrosion coolant. Mix strength should match the lowest expected ambient temperature; avoid plain water or a non-Komatsu coolant unless corrosion-inhibitor compatibility is confirmed. |
| Fuel tank | 55 L (14.5 US gal) per available spec listings for this model. Treat as approximate and confirm against the tank sight gauge or OMM, since capacity can vary by configuration/series. | No. 2-D diesel fuel, switching to No. 1-D or a winter blend in cold weather to prevent fuel gelling/waxing. Use low-sulfur diesel meeting the emissions requirement applicable to the operating region. |
| Hydraulic system total and hydraulic tank | Not documented for this exact serial range in available literature. Verify tank and total system volume against the OMM or dealer parts data; check level with the machine level, cylinders retracted, and oil at ambient temperature. | Komatsu Genuine hydraulic oil (HO series). HO46-HM (ISO VG46) is the general-purpose grade for -20C to 50C ambient; HO-MVK multi-grade (ISO VG32) covers a wider -30C to 50C range and eases cold starts. |
| Final drive (each) | Not documented for this exact serial range in available literature. Verify against the OMM fill/level-plug procedure for the final drive case. | Komatsu Genuine powertrain oil (TO series). TO30 (SAE 30) for normal ambient temperatures, or TO10 (SAE 10W) in cold climates. Meets Komatsu's powertrain performance standard for final drives and gearing, roughly equivalent to API GL-4. |
| Swing drive | Not documented for this exact serial range. Mini excavators in this weight class do not always carry a swing reduction case with its own oil fill separate from the hydraulic circuit; confirm in the OMM whether a distinct swing machinery case applies to this unit. | Where a distinct swing machinery case is fitted, use the same Komatsu Genuine powertrain oil (TO series, TO30 or TO10 by climate) specified for the final drives. |
| Grease (spec only) | Not a bulk-fill item; grease is applied per point per the lubrication-chart interval rather than a single system capacity. | Komatsu Genuine multipurpose lithium EP grease (G2-LI), NLGI 2, for boom, arm, bucket, and pin/bushing points. Use a low-temperature grease variant where ambient temperatures run consistently below freezing. |
Capacities are refill values from factory literature — always fill to the dipstick/sight gauge, not the number.

Servicing the PC38UU-2(S/N 3001-UP) beyond the schedule
Predictive Maintenance & Fluid Analysis
The 3D84-2GA has no ECM and throws no fault codes, so scheduled fluid sampling is the main early-warning tool on a machine this age. Pull engine oil at every change to watch for fuel dilution from a tiring mechanical injection pump and metal from valve-train wear. Sample the Komatsu HO-series hydraulic oil periodically; the compact, fixed-displacement circuit shows contamination fast, and rising particle counts often trace back to offset-boom pivot or cylinder seal wear before leaks appear.
Corrective & Common Repairs
Common corrective work centers on the offset-boom pivot: the dogleg boom that swings the bucket past the tracks carries heavier side load than a straight boom, so its pins and bushings wear faster and need regular replacement. Hard cold starts usually trace to glow plugs or a worn mechanical injection pump on the naturally aspirated 3D84-2GA, not electronics. Expect rubber track de-tracking, roller and idler seal weep, and wear in the dual-speed travel motors as routine running-gear repairs on machines this age.
Overhaul & Rebuild Points
At overhaul, the 3D84-2GA's modest displacement and output usually mean a top-end rebuild (rings, valves, injectors, injection-pump recalibration) restores compression and clean running rather than a full long-block swap. On the hydraulic side, rebuild or replace the pump and control valve once flow drops; this fixed-displacement circuit has no redundancy to mask wear. Reduction gear sets in the swing and dual-speed travel drives, plus a full pin, bushing, roller, and sprocket undercarriage rebuild using Komatsu TO-series gear oil, are typical once these machines push well past 4,000 hours.
Seasonal & Environment Servicing
Cold starts on the naturally aspirated 3D84-2GA depend on glow plugs, battery condition, and correct-viscosity Komatsu EO-series oil, since there is no ECM to compensate for temperature; switch to winter-blend diesel and full-strength AF-NAC coolant before freezing weather. In hot, dusty conditions, clean the radiator core and air cleaner more often than standard calls for, since this size engine bay traps debris fast. Wet or muddy digging accelerates offset-boom pivot wear, so shorten the G2-LI grease interval and hose down tracks to keep debris from cutting the rubber cord.

PC38UU-2(S/N 3001-UP) fault codes & troubleshooting
| Code | Meaning | Likely cause | What to do |
|---|---|---|---|
| Engine oil pressure warning lamp (red) | Engine lubrication oil pressure has dropped below the safe minimum. | Low oil level, worn oil pump, clogged oil filter, or a faulty oil pressure sender. | Stop the engine right away, check oil level and top up, inspect the filter and sender before restarting. |
| Charge warning lamp (red) | Alternator is not charging the battery. | Worn or slipping fan/alternator belt, faulty alternator, or a loose or corroded wiring connection. | Shut down as soon as safely possible, check belt tension and battery wiring, test alternator output. |
| Coolant temperature warning lamp / gauge red zone | Engine coolant temperature has exceeded the safe operating range. | Low coolant level, clogged radiator fins, failed thermostat, or a slipping fan belt. | Idle down and stop the engine, let it cool, check coolant level and radiator/fan belt before continuing work. |
| Air cleaner restriction indicator | Intake air filter element is clogged, restricting airflow to the engine. | Dust/debris buildup in the air filter element. | Stop the engine and clean or replace the air filter element, then reset the indicator. |
| Glow/preheat indicator lamp (amber) | Not a fault indicator; shows the intake air preheat glow system is active before cold starting. | Normal cold-start sequence; lamp stays on too long only if a glow element or relay has failed. | Wait for the lamp to go out before cranking; if preheat time is abnormally long or the engine won't start cold, check the glow plugs/relay and wiring. |
Codes and remedies are general guidance for this model family — always confirm with diagnostic tooling and your dealer before major repairs.
PC38UU-2(S/N 3001-UP) attachments & work tools
Buckets
Pin-on GP buckets typically run 300-900 mm (12-36 in) wide for this class, roughly 0.10-0.16 m3 (0.13-0.21 cu yd) struck capacity for standard digging and trenching profiles. Factory fitment is pin-on; coupler mounting is aftermarket only. HD/rock buckets in this weight class sit toward the lower end of that capacity range with reinforced sidewalls and bolt-on teeth.
Hydraulic hammers
Breaker class matches compact carriers in the 3-4 ton bracket: typical service weight 150-270 kg (330-595 lb), sized from small-frame breaker lines such as Okada, NPK, Indeco or Soosan built for this bracket. Required auxiliary flow runs about 20-60 L/min (5-16 gpm) at standard working pressure, within the stock auxiliary circuit. Going above this weight class risks boom stress and hydraulic overheating.
Quick couplers
Factory buckets are pin-on; couplers are aftermarket. Manual wedge/pin-grabber couplers sized for 2-4 ton carriers, with pin diameters around 30-40 mm, are the common fitment for this class. Hydraulic couplers exist for this size but are less common given the added cost and circuit demand on a compact machine.
Thumbs/grapples
Hydraulic thumb kits are a documented, regularly fitted option on this machine; reconditioned units are commonly sold factory-equipped with a hydraulic thumb, thumb cylinder stroke around 280-290 mm (11 in) and thumb width around 270 mm (11 in). Grapple fitment is not documented for this model; confirm with a dealer before speccing one.
Rippers
A dedicated single-shank ripper is not a standard or documented option for this compact excavator class. Some suppliers offer a bolt-on ripper tooth for the bucket edge instead of a standalone ripper attachment.
Hydraulic-kit notes
Combined main pump output is around 89 L/min (23.6 gpm) across the twin-pump system, but the regulated auxiliary flow available to tools like hammers and thumbs sits in the lower 20-60 L/min band typical of this weight class, a standard-pressure circuit rather than high-flow. No high-flow/two-speed auxiliary option is documented for this model; confirm circuit specs with a dealer before speccing a hammer near the top of its size class.

PC38UU-2(S/N 3001-UP) serial number reference
The serial/PIN tag is a stamped metal plate on the front of the machine between the two hydraulic boom foot mounts, sometimes with a duplicate plate on the revolving frame near the operator's seat base or boom base, attached with rivets or drive nails; Komatsu also die-stamps the number into the frame steel as a backup. On this compact excavator the plate reads the model designation followed by a plain numeric serial (for example, a number in the 3000s) with no letter prefix to decode, unlike larger Komatsu iron that uses longer VIN-style PINs.
| Prefix | Identifies | Notes |
|---|---|---|
| 3001-UP (no 3-character alpha prefix documented) | Standard PC38UU-2 zero-tail-swing mini excavator, single continuous production run | Factory parts book and dealer listings designate the whole PC38UU-2 line as one serial block starting at 3001, with plain numeric serials only (no letter prefix like larger Komatsu machines use). Real-world units carry serials such as 3150 and other numbers in the low 3000s, consistent with this block. Built in Japan. Fitted with a 3D84-series diesel (3D84-2GA), about 22 kW (30 hp), roughly 1.4 L displacement. Two-piece offset boom and dual-speed travel are standard across the run. No sub-prefix or plant-code split turned up for this block; confirm any unusual serial with a dealer. The PC38UU-2E is a separate model number built with a different Yanmar-made 3D84E-3C engine and is not part of this 3001-UP block. |
Frequently asked questions
What engine does the Komatsu PC38UU-2 (S/N 3001-UP) use?
It runs a Komatsu 3D84-2GA diesel: 3-cylinder, water-cooled, naturally aspirated, about 1.4 L displacement, mechanically governed with no electronic engine control. Rated output is around 22.4 kW (30 hp) gross at 2,700 rpm.
What is the operating weight of the PC38UU-2 (S/N 3001-UP)?
Operating weight is approximately 3,690 kg (8,136 lb) in typical trim. Individual listings show a spread of roughly 3.47-3.8 tonne depending on the bucket, blade, and hydraulic thumb fitted.
What replaced the Komatsu PC38UU-2?
Komatsu ran the PC38UU-2E "Avance" cab variant, a separate model with a larger 3D84E-3C engine, alongside this line, then carried the numbered series forward through PC38UU-3 and later generations up to today's PC38UU-6, each update bringing a revised engine and emissions compliance.
What PC38UU-2(S/N 3001-UP) owners discuss
What do operators generally say about the PC38UU-2's overall hydraulic reliability?
Owners describe the hydraulic system as generally sound when maintained, but weak or sluggish auxiliary functions show up as the machine ages, most often traced to worn ram seals, a tired main pump, or a failing travel or swing motor rather than one design flaw. On units where power fades under load across all attachments, a shop pressure test at the pump and at each cylinder isolates whether the pump or a downstream seal is losing pressure. Have your dealer verify pump output and relief-valve settings before condemning a component.
Is premature undercarriage wear a known issue on this machine?
Yes. As a compact zero-tail-swing machine running on rubber tracks, owners report rubber pads wearing faster than a steel-shoe machine would, especially on abrasive or rocky ground, and track tension needing more frequent adjustment than expected. The tensioner is a grease-filled cylinder near the idler, and letting tension run loose accelerates wear on the idler and rollers along with the track itself. Regular tension checks and matching ground conditions to the track type are the common fixes discussed among owners.
What engine quirks come up for this machine?
The PC38UU-2 runs a Komatsu 3D84-2 series mechanical diesel rated around 22 kW (30 hp), with no ECM and no electronic sensor network, so most starting or power complaints trace back to fuel delivery (clogged filters, air in the line) or cooling (a blocked radiator core) rather than electronics. Because governing is fully mechanical, cold starts depend on healthy glow plugs and clean injectors; one weak glow plug or a gummed injector shows up as hard cold starting before anything else changes. During in-frame rebuilds, techs flag that timing gear and camshaft timing marks on this engine family are easy to misalign, so that step gets called out specifically in rebuild discussions.
Are there common electrical or instrument-panel complaints?
The wiring and gauge cluster are simple next to later electronic excavators, so most electrical complaints are basic: corroded or loose battery terminals causing no-start or intermittent power, and a warning light on the panel that owners cannot decode on their own. Many PC38UU-2 units in North America arrived through personal or non-dealer import channels, and some instrument clusters carry Japanese-language labeling with no local factory translation on hand, which makes a lit warning symbol hard to diagnose without the correct manual. Check battery connections first, then get the panel symbol identified against the correct manual before assuming a sensor fault.
What does a boom that will not lift, or lifts weakly, usually point to?
Troubleshooting for this complaint generally follows the same sequence: confirm the pump is putting out full flow and pressure, pressure-test the boom ram and its hoses for internal bypass, then inspect the ram seals for wear. A ram that holds under a dead-engine load test but sinks slowly with the engine running points to a valve or pump issue rather than the cylinder itself. Because an unexpected boom drop is a crush hazard, have your dealer verify ram integrity and system pressure readings before returning the machine to service.
What should a buyer check before purchasing a used PC38UU-2?
Walk the machine cold first: look for weld cracks or rust lines at the boom, arm, and bucket linkage, and check underneath for fresh oil staining. With the tracks raised, inspect rubber pads for cuts, dry rot, or thin spots and check remaining life on rollers, idlers, and sprockets on both sides. Start the engine cold, confirm a smooth idle and normal exhaust color, then run the boom and arm to full extension and watch for cylinder drift or sinking, cycling every function together to load the pump. Check hydraulic oil color at the sight gauge or dipstick, which should run clear amber rather than dark or milky, and dig in real ground instead of just cycling in air, since a machine that swings fine empty can bog down under load. Confirm the serial number and generation markings match what the seller represents, since import units and reman machines can carry mismatched tags.
Is parts availability a concern owners raise for this model?
Yes, it comes up regularly. Many PC38UU-2 units sold in North America came in through personal-import or non-dealer channels rather than the standard dealer network, and owners report longer lead times and more legwork sourcing engine, hydraulic, and undercarriage parts than they would for a mainstream dealer-network machine. Confirming the exact serial range before ordering matters more than usual here, since visually similar components can differ between the earlier and later generation, or between import- and domestic-spec builds.
Compiled from owner and technician discussions across the industry — experiences vary by serial range and machine history.
