Komatsu PC400(S/N 10351-UP (Mighty Spec))
Maintenance schedule, common problems & OEM parts breakdown
The PC400 (S/N 10351-UP, Mighty Spec) is a large hydraulic crawler excavator in Komatsu's 40-plus metric ton class, built within the PC400-5 generation alongside the standard PC400-5, long-undercarriage PC400LC-5, and PC400HD-5. It runs a Komatsu S6D125-1 series turbocharged direct-injection diesel rated around 206 kW (276 hp) flywheel, with no electronic emissions aftertreatment, keeping the powertrain mechanically simple by later standards. Operating weight runs roughly 40.6 to 44.5 metric tons (about 89,600 to 98,100 lb) depending on undercarriage length, bucket, and counterweight fitted, with the Mighty spec sitting at the heavier, more reinforced end of that band. This generation was produced roughly from the late 1980s through the 1990s, following the earlier PC400 and PC400-3 (mid-1980s to mid-1990s) and giving way to the PC400-6 in the mid-to-late 1990s. Configurations offered included standard, long-undercarriage LC, heavy-duty HD, and the Mighty spec covered here, aimed at rock and quarry duty with a larger-capacity bucket and beefed-up structure.
The Mighty spec added a reinforced boom, arm, and undercarriage plus a larger-capacity bucket and heavier counterweight compared to the standard PC400-5/PC400LC-5, trading some cycle speed for durability in rock and quarry loading. Across later PC400 generations Komatsu moved the engine line to electronically governed, emissions-certified SAA6D125E variants and shifted the hydraulic system toward load-sensing control, both of which added complexity and cost to service. That makes this earlier Mighty spec machine attractive today in the used and parts market: it is mechanically straightforward, shares major driveline and hydraulic components with the wider PC400-3/PC400-5 family, and its rock-duty structure holds up well as a rebuild candidate where simplicity and parts availability matter more than the latest emissions compliance.

PC400(S/N 10351-UP (Mighty Spec)) fluids & capacities
| System | Capacity | Recommended fluid |
|---|---|---|
| Engine crankcase (oil pan, with filter) | Specified 38 L (10.0 US gal, 8.4 UK gal); refill 32 L (8.5 US gal, 7.0 UK gal) | Komatsu genuine engine oil (this era spec-plated as Komatsu Dresser Co. oil). Grade by ambient temp: SAE 10W below 0°C (32°F), SAE 30 in warm range, SAE 15W-40 or SAE 10W-30 as an all-season multigrade. API CF-4 or CG-4 required; if only API CD is available, cut the oil change interval in half. Single-grade oil can be topped off into multigrade but must match the temperature band. Change interval shortens (to half at 0.5-1.0% sulphur, to a quarter above 1.0%) if local diesel sulphur content is high. |
| Cooling system | Specified 34 L (9.0 US gal, 7.5 UK gal); refill 22 L (5.8 US gal, 4.8 UK gal) | Water plus Komatsu genuine antifreeze (ethylene-glycol type). Antifreeze mix ratio is set from a temperature chart in the manual and rises as ambient temperature drops — use the ratio for the coldest expected temperature, not the current one. Keep coolant level between FULL and LOW on the reserve tank. |
| Fuel tank | 550 L (145 US gal, 121 UK gal) | Diesel fuel to ASTM D975 No. 1 for cold/winter operation; a No. 2 grade applies in warmer conditions per the same seasonal chart. Use low-sulphur fuel where available — high-sulphur fuel forces shorter engine oil change intervals. |
| Hydraulic system (total, incl. piping and components) | 460 L (121.5 US gal, 101.2 UK gal) specified | Same engine-oil-grade fluid as the crankcase on this generation (SAE 10W / SAE 30 / SAE 10W-30 / SAE 15W-40 by ambient temperature, API CF-4 or CG-4). Komatsu genuine oil recommended. Bleed air from pump, control valve, cylinders, swing motor and travel motor after any hydraulic service. |
| Hydraulic tank (refill / service-fill amount) | 255 L (67.4 US gal, 56.1 UK gal) | Same fluid as hydraulic system total, above. Change interval is roughly every 2000 hours; clean strainer and replace return/line filter elements at the same time and bleed air afterward. |
| Final drive (each) | 11.5 L (3.0 US gal, 2.5 UK gal) per side | Komatsu genuine engine oil, same SAE-grade-by-temperature chart as the crankcase (SAE 10W / 30 / 10W-30 / 15W-40, API CF-4 or CG-4). |
| Swing drive (swing machinery case) | 24 L (6.3 US gal, 5.3 UK gal) | Komatsu genuine engine oil, same SAE-grade-by-temperature chart as the crankcase (SAE 10W / 30 / 10W-30 / 15W-40, API CF-4 or CG-4). |
| Damper case (pilot/other circuit) | 1.07 L (0.28 US gal, 0.24 UK gal) | Komatsu genuine engine oil, same SAE-grade-by-temperature chart as the crankcase. |
| Grease (spec only) | Not a fill-volume item — per standard Komatsu grease-point schedule for this class of excavator | Komatsu Genuine Grease G2-LI, a lithium-base EP2 (NLGI 2) grease, for general pin and bushing lubrication points. Where the lube chart calls for extreme-pressure duty (heavily loaded pins), Komatsu's molybdenum-disulphide-fortified grease applies instead — confirm point-by-point against the lubrication chart for this serial range. |
Capacities are refill values from factory literature — always fill to the dipstick/sight gauge, not the number.

Servicing the PC400(S/N 10351-UP (Mighty Spec)) beyond the schedule
Predictive Maintenance and Fluid Analysis
Sample engine oil, final drive case oil, swing machinery case oil, and hydraulic tank oil on a set schedule to track wear metals from the S6D125-1 diesel, planetary final drives, and main pump set. Watch hydraulic oil for water and metal fines, a leading indicator of main pump or swing motor wear on this open-center system. Monitor coolant condition and corrosion inhibitor level given the mechanically governed, non-aftertreatment engine's reliance on clean coolant and fuel for injector life.
Corrective and Common Repairs
Swing lockups on these machines usually trace to swing motor or swing valve wear rather than the motor itself; check hydraulic pressure and the swing circuit before condemning parts. Travel motors are prone to shaft seal failure when the counterbalance or safety valve inside the motor degrades, pressurizing the final drive case and pushing oil past the seal. On the S6D125-1, watch for injector and fuel filter fouling from water-contaminated fuel, and inspect final drive bearings for the play that precedes gear damage.
Overhaul and Rebuild Points
At high hours, plan for main hydraulic pump reman or rebuild, turbocharger overhaul, and swing machinery case gear and bearing renewal alongside the scheduled oil change. Final drive planetary sets and travel motors are common full-teardown items given the added stress of the Mighty spec's heavier counterweight and reinforced structure. Inspect the undercarriage - triple-grouser shoes, sprockets, idlers, and rollers - closely, since the reinforced Mighty-spec chassis runs heavier loads than the standard PC400-5 undercarriage.
Seasonal and Environment Servicing
In quarry and rock environments, clean the air cleaner elements and radiator, oil cooler, and aftercooler fins more often than the standard interval to offset heavy dust loading feeding the turbocharged S6D125-1. In cold climates, use a winter-grade fuel and coolant mix, check the battery and starting aid, and verify the block heater or ether-start system before shutdown, since this generation lacks modern automatic cold-start electronics. Keep hydraulic oil viscosity matched to season to protect the main pump and swing/travel motors.

PC400(S/N 10351-UP (Mighty Spec)) fault codes & troubleshooting
| Code | Meaning | Likely cause | What to do |
|---|---|---|---|
| Engine oil pressure warning lamp (red pictograph, no alphanumeric code) | Engine oil pressure has fallen below the normal operating pressure; listed as an emergency-stop item on the monitor panel | Low engine oil level, clogged oil filter, failing oil pump, or worn engine bearings | Stop the engine immediately, check oil level and filter condition, and do not restart until the cause is found and corrected |
| Radiator coolant level warning lamp (red pictograph, no alphanumeric code) | Coolant level in the radiator or reserve tank has dropped too low; shown as both a pre-start basic-check item and an emergency-stop item | Coolant leak, blown hose, loose clamp, or evaporation loss not topped up | Stop and let the engine cool, inspect for leaks, then check and refill coolant to the correct level in the radiator and reserve tank |
| Engine coolant temperature warning lamp (red pictograph, no alphanumeric code) | Engine coolant temperature has moved into the gauge's red range; the monitor drops power mode and, if temperature keeps climbing, cuts engine speed to low idle with the buzzer sounding | Low coolant, clogged or dirty radiator fins, slipping or broken fan belt, faulty thermostat | Bring the engine to low idle, let the temperature drop back into the green range, then check coolant level, radiator fins, and fan belt before resuming work |
| Charge (alternator) warning lamp (red pictograph, no alphanumeric code) | Charging circuit is not charging correctly while the engine is running | Broken or slipping fan/alternator belt, faulty alternator, loose or corroded wiring connection | Check belt tension and condition first, then inspect alternator wiring and connections; have the charging circuit tested if the lamp stays on |
| Air cleaner dust (clogging) indicator (mechanical pop-up indicator on the air cleaner body, not a monitor-panel lamp) | Intake restriction across the air cleaner element has reached the point where the dust indicator has popped and shows red | Dirty or clogged air filter element, damaged element seal, restricted intake ducting | Clean or replace the air cleaner element, reset the dust indicator, and check intake ducting for damage or blockage |
| Fuel gauge low-fuel warning (red segment on the fuel gauge, no alphanumeric code) | Fuel gauge needle has moved into the gauge's red zone, showing the tank near reserve | Normal fuel consumption without refueling, or a fuel leak | Refuel, and inspect the tank and fuel lines for leaks if fuel is running low faster than expected |
Codes and remedies are general guidance for this model family — always confirm with diagnostic tooling and your dealer before major repairs.
PC400(S/N 10351-UP (Mighty Spec)) attachments & work tools
Buckets
This machine sits in the 40-43 tonne class, and factory/dealer bucket literature for that class runs roughly 1.4-2.2 m3 (1.8-2.9 yd3) depending on GD (general purpose) vs HD/rock duty. Pin-on mounting is standard, with a 100 mm (approx. 3.9 in) bucket pin diameter typical for this size range; aftermarket severe-duty buckets for this class are commonly built in widths from about 1067 to 1676 mm (42-66 in). Coupler-mounted buckets are usable once a matching quick coupler is fitted.
Hydraulic hammers
Komatsu's own breaker line spans small units up to a roughly 70-tonne carrier class, and a 40-43 tonne machine like this falls in the upper-middle of that range. Independent breaker makers size their large-class hammers (used across the 35-45 tonne carrier bracket) with tool weights commonly in the low-to-mid multi-tonne range; exact model and weight class varies by hammer brand and series, so match by carrier weight and flow/pressure rating rather than by name alone.
Quick couplers
Both manual (pin) and hydraulic (in-cab actuated) quick couplers are built for this machine's size class, sized around the same roughly 100 mm pin diameter used on its buckets. Hydraulic couplers let the operator swap buckets, thumbs, or other pin-on tools without leaving the cab; manual couplers are the lower-cost alternative requiring the operator to pin attachments by hand.
Thumbs/grapples
Hydraulic thumb kits (bucket-mounted, hydraulically actuated) and hydraulic or rotating grapples are offered for this size class, built to the stick and bucket pin spacing of the specific machine. Because pin diameter and bucket linkage geometry differ across Komatsu excavator generations, thumb and grapple kits are typically sold as fitted-to-model rather than universal.
Rippers
Single-shank ripper attachments are available for this weight class, used for pavement removal, hard-soil digging, and breaking rock ahead of digging rather than continuous ripping. They mount in place of or alongside the bucket linkage and use a replaceable ripper tip/tooth for wear.
Hydraulic-kit notes
Running a hydraulic hammer or other flow-hungry tool on this machine requires a dedicated auxiliary (breaker) circuit; aftermarket piping kits for this class add the steel lines, hoses, and control/service valve needed when the machine was not already fitted with one. Confirm the machine's actual auxiliary circuit pressure and flow rating with a dealer before matching a hammer or high-flow tool, since factory circuit spec on this serial range is not fully documented in general literature.

PC400(S/N 10351-UP (Mighty Spec)) serial number reference
On this generation, the serial/PIN is stamped into the machine's main frame at the front, between the boom foot (hydraulic arm) mounts, and is typically covered by a Komatsu ID decal. This generation predates Komatsu's later 17-character PIN format, so there is no alpha prefix to look for -- read the full stamped numeric string itself (e.g., 10351 and up); that number is the production break that identifies the spec/family, so match it directly against the serial ranges listed for parts and service coverage.
| Prefix | Identifies | Notes |
|---|---|---|
| 10351 | PC400-5 Mighty Spec (standard undercarriage) | Serial break for the Mighty Spec configuration of this generation. Factory shop-manual coverage groups this Mighty Spec unit together with the standard, long-undercarriage, and heavy-duty-undercarriage versions of the same generation under one manual set, indicating a shared production era rather than a separate design. Engine is from the S6D125-1 turbocharged family; the exact block suffix (S6D125-1, -1W, or -1VV) can change at an in-production engine-serial breakpoint that falls inside this machine-serial range rather than at the machine serial break itself, so confirm the exact engine suffix stamped on your unit with a dealer. Production era for this generation runs roughly late 1980s into the mid-1990s. Some parts/manual coverage tied to the Mighty designation references a later serial breakpoint in the 20000s -- treat that as a possible mid-run documentation split and confirm against your machine's actual stamped serial with a dealer rather than assuming it applies here. |
Frequently asked questions
What engine does the Komatsu PC400 (S/N 10351-UP, Mighty Spec) use?
It runs a Komatsu S6D125-1 series turbocharged direct-injection diesel, rated at roughly 206 kW (276 hp) flywheel. It is a mechanically governed engine without electronic emissions aftertreatment, matching this generation's PC400-5-family driveline.
What is the operating weight of the PC400 (S/N 10351-UP, Mighty Spec)?
Operating weight runs roughly 40.6 to 44.5 metric tons (about 89,600 to 98,100 lb), varying by undercarriage length, bucket, and counterweight fitted. The Mighty spec's reinforced structure and larger bucket put it toward the heavier end of that range versus the standard PC400-5.
What replaced the PC400 (S/N 10351-UP, Mighty Spec)?
It was succeeded by the PC400-6, followed by the PC400-7 and PC400-8 generations, which moved to electronically controlled, emissions-certified engines and load-sensing hydraulics.
What PC400(S/N 10351-UP (Mighty Spec)) owners discuss
What engine and generation does a PC400 (S/N 10351-UP, Mighty Spec) actually have?
This serial run sits in the PC400-5 generation, built around the S6D125-1 six-cylinder diesel with a mechanical in-line Bosch-style injection pump and no electronic engine management or digital monitor codes - that came later with dash-6 and dash-7 machines. The factory parts book covers Mighty Spec alongside the standard PC400-5/PC400LC-5 in the same 10351-up serial window as a higher-output injection/turbo calibration on the same base engine casting, not a different powerplant. In the field, mechanics and owners rarely distinguish Mighty from a standard-spec PC400-5 day to day; failure modes and parts interchange track the base engine family. Because this same serial window also covers Overseas, Custom, and other regional spec calibrations, confirm the exact spec code off the machine's plate before ordering injection-pump internals - calibrations differ even though the block looks identical.
Why do the hydraulic controls go sluggish or erratic on this machine as the oil warms up?
This is a well-worn complaint on PC400-5 era machines: everything feels fine cold, then boom/arm/bucket response gets soft or inconsistent once hydraulic oil is up to temperature. The usual suspects, in rough order of likelihood, are a worn or scored main relief/safety valve no longer holding set pressure, worn spool valves in the control valve bank allowing internal bypass, and a sticking or misaligned safety (disconnect) lever linkage that keeps pilot pressure from fully engaging. Cold oil masks the wear because higher viscosity reduces the bypass leakage; heat exposes it. Start with a pressure test at the main relief and the two-stage boom-up relief before tearing into the valve bank - a scored relief seat is a common, fixable root cause. Relief valve pressures affect lift capacity and control response, so have your dealer verify any relief valve adjustment or replacement against factory spec.
Is there a known engine quirk on this PC400-5 platform involving coolant or water showing up in the crankcase?
Yes - it's a recognized failure path on the S6D125-1 engine family used across this serial range. Water intrusion into the oil usually traces to leaking cylinder liner seals (liner O-rings breaking down or the liner shifting slightly in the block) or a failing water pump/front timing cover seal, sometimes triggered by a seized fan clutch loading the water pump bearing axially in dusty operating environments. Milky oil, a rising coolant level that won't hold, or unexplained coolant loss with no external leak are the tells. Left alone this leads to diluted lube oil, bearing wear, and in worse cases a hydro-locked cylinder on startup. Pull an oil sample and pressure-test the cooling system at the first sign of coolant loss. Because this affects internal engine integrity, have your dealer verify liner seal and water pump condition before returning the machine to service.
What undercarriage and wear patterns are typical for a machine in this weight class and era?
Same story owners report across 40-plus tonne Komatsu excavators of this generation: track tension is the first thing to go out of spec, usually from grease fitting leakage in the tensioner, and a track that's too loose accelerates bushing and sprocket wear while a track run too tight burns through pins and bushings faster from added friction. Uneven shoe wear shows up when the shoe width doesn't match ground conditions - running wider shoes than needed loads the shoes and hardware unevenly. In wet clay or sticky ground, packing between the rollers and shoes intensifies wear, saps power, and pushes fuel consumption up until it's cleaned out. A daily walk-around checking tension, shoe bolts, and roller/idler seals for weeping oil catches most of this before it becomes a bushing or sprocket replacement job.
What's the story with swing motor and final drive complaints on these machines?
Two recurring themes show up in mechanic write-ups on this platform. First, travel (final drive) motors can blow a shaft seal and pressurize the final drive case, which shows up as low case-drain flow compared to the shop manual's spec and max-allowable figures. Second, because the final drives and the swing motor typically share a common case-drain return line to tank, a failing motor on one end of the machine can push enough case pressure back through that shared line to make a healthy motor look like it's failing too - so a case-drain test in isolation (one motor at a time, line disconnected from the shared return) is the only way to pin down which motor is actually bad. Swing lock-up after a motor failure is described as sudden and complete, since the machine loses swing hydraulic pressure the moment the motor lets go. Given the pressure and rotating-mass risk involved in swing/travel motor work, have your dealer verify case-drain test results before committing to a motor teardown.
What electrical or sensor issues come up on this era of PC400, and how does it differ from later dash-6/dash-7 machines?
This generation runs a conventional analog gauge cluster and warning-lamp panel rather than the digital monitor and fault-code system Komatsu introduced on later dash-6 and dash-7 PC400s - so if you're chasing an "E-code" or KOMTRAX-style diagnostic on this machine, that's the wrong generation's troubleshooting guide. What owners do report on machines this age: corrosion inside connectors and behind the gauge cluster from years of vibration and moisture, weak batteries and worn wiring harnesses causing intermittent shutdowns or hard starts, and coolant-temperature sender failures that trip a temp warning lamp even though the gauge and actual coolant temp are normal. Multimeter checks at the cluster, cleaning/re-terminating dash connectors, and swapping a suspect temp sender resolve most of these without touching the wiring harness itself.
What should I check before buying a used PC400 (S/N 10351-UP, Mighty Spec)?
Start with the serial/spec plate and match it against the parts book - this exact serial window also covers Overseas, Custom, and other regional spec variants with different engine and hydraulic calibrations, so confirm you're actually looking at a Mighty Spec machine before assuming parts interchange. Run every hydraulic function cold, then again after 20-30 minutes of work to see if response drops off - that's the classic sign of a tired main relief valve or worn spool valves on this platform. Pull an engine oil sample or at minimum check the dipstick for milky discoloration, since coolant-in-crankcase from liner seal or water pump failure is a known issue on this engine family. Check final drive and swing motor case-drain flow if you can, and walk the undercarriage measuring track sag and shoe/bushing wear rather than eyeballing it. Ask for service records showing relief valve, injection pump, and undercarriage work. Given the age and hour range typical of machines in this serial run, have your dealer verify hydraulic pressures, case-drain flow, and engine blow-by/compression before finalizing a purchase.
