Komatsu PC4000-6(S/N 08152)
Maintenance schedule, common problems & OEM parts breakdown
The Komatsu PC4000-6 is a large hydraulic mining shovel in Komatsu's surface-mining excavator range, built at the former O&K/Demag plant in Dusseldorf, Germany. It runs a Komatsu SDA16V160 16-cylinder, water-cooled, turbocharged and aftercooled diesel rated near 1400 kW (1875 HP) at 1800 rpm; later units in the -6 run, from around S/N 08199 up, carry the Tier 2-certified SDA16V160E-2 version of the same base engine. Operating weight runs roughly 388-399 t (855,500-879,800 lb) depending on the front end fitted. Komatsu offered the PC4000-6 as either a hydraulic front shovel or a mass-excavation backhoe, both matched to a roughly 22 m3 (29 yd3) bucket and sized to load haul trucks in the 150-240 t payload class. The -6 series followed the original Tier 1 PC4000 and was succeeded around 2018 by the Tier 4 Final PC4000-11, which added selective catalytic reduction and a heavier operating-weight range.
Within the -6 generation, the main running change was emissions: the base SDA16V160 engine gave way to the Tier 2-certified SDA16V160E-2 partway through production, with the factory manual break documented at S/N 08199 and up. S/N 08152 predates that update and runs the earlier engine with its mechanical-unit-injector fuel system. Beyond the engine, Komatsu offered the -6 in shovel and backhoe front-end configurations with matching wear-package and track-shoe options, so buyers should confirm the exact build against the unit's own dataplate rather than assume from the model name alone. On the used and parts market, PC4000-6 units stay in demand because the platform logs extremely long service lives in continuous mining duty, with Komatsu citing individual units passing 170,000 hours, and because sourcing for the earlier engine and hydraulic componentry is a real consideration. The newer PC4000-11 has moved to a common-rail fuel system and different emissions hardware, so parts and service knowledge for -6-era units like this one increasingly sits with dealers and specialists who still support the earlier engine generation.

PC4000-6(S/N 08152) fluids & capacities
| System | Capacity | Recommended fluid |
|---|---|---|
| Engine crankcase (with filter) | 290 L (77 US gal) | Komatsu Genuine Diesel Engine Oil, EO10W30-DH or EO15W40-DH grade (meets JASO DH-1, API CI-4). Select 10W-30 for wider cold-start range, 15W-40 for hot ambient; on emissions-certified engines fitted with a particulate filter, use the Komatsu Low Ash EO-LA (or Ultra Low Ash EO-ULA) grade instead. Follow the viscosity-by-ambient-temperature chart in the OMM for this serial range. |
| Engine oil reserve / make-up tank (Centinel and Reserve oil system) | 460 L (122 US gal) | Same grade as the engine crankcase fill. This tank feeds the automatic oil-replenishment system and works with the self-cleaning oil filter to extend drain intervals; keep it topped with the identical oil grade in use. |
| Cooling system | 475 L (125 US gal) | Komatsu Genuine Super Coolant AF-NAC, a long-life ethylene-glycol coolant with a non-amine, non-nitrite corrosion-inhibitor package. Provides freeze protection in cold climates and scale/cavitation protection year round; do not mix with conventional green coolant. |
| Fuel tank | 6,400 L (1,691 US gal) | Clean, low- or ultra-low-sulfur diesel fuel matching the engine's emissions certification tier. Use a winter-grade or treated blend in cold climates to prevent gelling. |
| Hydraulic oil tank | 3,900 L (1,030 US gal) | Komatsu Genuine Hydraulic Oil HO46-HM (ISO VG46 multigrade, meets DIN 51524 Part 2 HLP). A biodegradable hydraulic oil (Komatsu BO46G4, ISO VG46) is offered for environmentally sensitive sites. Grade may shift with ambient temperature per the OMM viscosity chart; a lighter multigrade is used in cold climates. |
| Hydraulic system, total (tank, lines, coolers, cylinders) | 5,900 L (1,559 US gal) | Same Komatsu Genuine hydraulic oil as the tank fill (HO46-HM or the biodegradable BO46G4 option). |
| Swing and travel drive reduction gearboxes | Not broken out as a separate service capacity in the available documentation; swing and travel are hydraulic-motor-driven planetary reduction units serviced through the machine's central hydraulic and lubrication systems. | Where a dedicated gearbox fill point is called out in the OMM lubrication chart, Komatsu specifies its TO-series powertrain gear oil (TO10 or TO30 grade, API CD-level anti-wear/anti-scuffing performance) for final-drive and swing-reduction housings on this equipment class. Confirm the exact fill point and interval against the OMM for this serial range. |
| Automatic central lubrication, chassis and attachment grease | 200 L (53 US gal) refillable barrel | Komatsu Genuine multi-purpose lithium EP grease (NLGI 2 consistency), rated for roughly -20 degC to +120 degC service. A softer low-temperature grease is substituted for machines running in arctic climates per the cold-weather package. |
| Automatic central lubrication, swing ring open-gear lube | Second, identical 200 L (53 US gal) barrel system, fed through a lube pinion to the external swing ring teeth | Komatsu-specified open-gear lubricant for the swing circle, applied through the same automatic single-line lube system architecture as the chassis grease; refilled through the Wiggins service-arm connections. |
Capacities are refill values from factory literature — always fill to the dipstick/sight gauge, not the number.

Servicing the PC4000-6(S/N 08152) beyond the schedule
Predictive Maintenance & Fluid Analysis
Oil sampling drives service decisions on this shovel more than the calendar does. The engine runs a Centinel reserve-oil tank and self-cleaning filter that support extended drain intervals, so trend the oil analysis instead of guessing a fixed change point. Hydraulic contamination is the number-one failure driver reported on this platform: sample the roughly 3900 L (1030 gal) hydraulic tank regularly and watch for early signs in cylinder response, pump noise, or oil temperature before a seal or pump actually fails. Track VHMS fault history alongside sample results to catch trends early.
Corrective & Common Repairs
Weeping rod seals on the boom, arm/stick and bucket or clam cylinders are the most-repeated repair on this shovel; catch them early with a walk-down rather than waiting for visible oil loss. Swing motors, the center joint and travel final drives are high-turnover items at this weight class; grinding or whining on swing or travel usually traces to low oil, contamination or bearing wear in the reduction unit, not the hydraulic motor. Validate a single VHMS sensor fault against its connector before swapping parts. Wiring and grounding cause more nuisance codes than failed transducers on this generation.
Overhaul & Rebuild Points
S/N 08152 sits in the early -6 production run, ahead of the Tier 2 engine block introduced around S/N 08199. Its SDA16V160 engine uses mechanical unit injectors (HPI) rather than the common-rail system on later Komatsu big-bore diesels, so budget longer lead times sourcing injection parts for a top-end overhaul. Bleed the pilot-circuit accumulators at the test port before any hydraulic line work; have a qualified tech confirm correct discharge first. Plan swing-ring bearing, open-gear and final-drive planetary rebuilds around oil-sample metal trending, not a fixed hour count.
Seasonal & Environment Servicing
This shovel runs from arctic pits to hot, dusty surface mines, and Komatsu's cold-weather package substitutes a softer low-temperature grease in the automatic lube system where ambient stays well below freezing. Match hydraulic and engine oil viscosity grades to the season per the OMM chart rather than running one grade year-round. In hot, dusty operation, clean the hydraulic oil cooler and radiator cores more often than the standard interval, and check the air-cleaner restriction indicator daily; packed dust cuts cooling capacity and starves the turbo faster on a machine this size.

PC4000-6(S/N 08152) fault codes & troubleshooting
| Code | Meaning | Likely cause | What to do |
|---|---|---|---|
| ENGINE AIR FILTER RESTRICTION | Intake air filter restriction indicator warns that vacuum across the air cleaner has exceeded the allowed limit, signaling reduced airflow to the turbocharger. | Clogged primary (and/or safety) air filter element, blocked intake ducting, or a fouled restriction sensor/indicator line. | Check the restriction indicator/gauge, inspect and clean or replace the primary filter element, and verify intake ducting is clear before restarting. |
| ENGINE OIL PRESSURE LOW | Engine protection system flags oil pressure below the safe threshold at the current speed; triggers a warning and can force an automatic power cutback or shutdown. | Low oil level, failing oil pressure sensor or wiring, plugged oil filter, or worn oil pump. | Shut the engine down safely, check oil level and condition, inspect the pressure sensor and its wiring, and check filter condition before attempting a restart. |
| ENGINE COOLANT TEMPERATURE HIGH | Coolant temperature has exceeded the safe operating limit; the monitor issues a warning and can command a power derate or shutdown to protect the engine. | Low coolant level, fouled or blocked radiator/cooler core, faulty coolant temperature sensor, or a cooling fan drive fault. | Reduce load and idle the engine, check coolant level and the radiator core for debris, and inspect the temperature sensor and fan drive. |
| ENGINE OVERSPEED | The electronic governor detects engine speed above its set limit and cuts fuel or shuts the engine down to prevent mechanical damage. | Governor actuator malfunction, faulty magnetic speed pickup or wiring, or a binding fuel linkage on the all-speed electronic governor. | Stop the machine, inspect the governor actuator and speed sensor air gap/wiring, and check the fuel control linkage for binding before restart. |
| HYDRAULIC OIL TEMPERATURE HIGH | Main hydraulic tank or return-line oil temperature has exceeded the set limit; the monitor warns the operator to protect pumps and valves from thermal damage. | Low hydraulic oil level, a fouled or undersized-flow oil cooler, degraded hydraulic oil, or a cooling fan fault. | Lower the attachment, let the engine idle to cool the system, check oil level and cooler core cleanliness, and verify the cooling fan is operating. |
| VHMS FAILURE MESSAGE (Top Message) | The Vehicle Health Monitoring System logs a general abnormality alert any time a monitored engine, hydraulic, or electrical parameter goes out of tolerance; the message is shown on the cab touch-screen and stored in the Failure Message History. | Varies by triggering system - any monitored sensor or circuit deviation captured by the VHMS/MTC control system. | Open the Failure Message History (Top Messages) screen on the cab monitor, record the exact message text and timestamp, and refer the data to a Komatsu dealer for VHMS-level diagnosis. |
Codes and remedies are general guidance for this model family — always confirm with diagnostic tooling and your dealer before major repairs.
PC4000-6(S/N 08152) attachments & work tools
Front-end configuration
Offered as a hydraulic front shovel or as a backhoe (mass-excavation) front. The shovel front uses a shorter boom with a crowd-arm bucket for face loading into trucks; the backhoe front uses a longer boom and stick for below-grade digging, with correspondingly different digging geometry. Changing between fronts is a kitted shop conversion, not an operator quick-change, and shifts machine operating weight by several tonnes.
Bucket capacity class
Standard bucket is rated around 22 m3 (29 yd3) SAE heaped in either front (SAE 2:1 heaped basis for the shovel front, SAE 1:1 heaped for the backhoe front). Bucket sizing in this class is matched to the haul fleet, this machine is positioned to load trucks in the roughly 150-240 t payload range; heavier wear-package or reduced-capacity buckets are selected per dig material density.
Ground engaging tools / wear package
Buckets use a bolt-on tooth-and-adapter GET system rather than integral cast teeth, drawn from Komatsu-supplied programs (systems marketed under names such as KVX and Kprime, with Hensley-compatible hardware also fitted in the field). Lip shrouds and side/heel wear protection are added as a wear package to slow abrasive lip wear; tooth profile (straight, semi-delta, or delta lip) is matched to the bucket lip style ordered.
Bucket mounting / coupler
No quick-coupler is used at this size class. The bucket pins directly to the stick (backhoe) or arm (shovel) and is actuated by dedicated bucket-close/crowd hydraulic cylinders that are shielded within the attachment structure to protect them from face material. Bucket swaps are a pinned, crane-assisted shop task rather than an operator-level quick-change.
Undercarriage / track options
Standard undercarriage runs cast-steel track shoes on the order of 1200 mm (47 in) wide with a center carbody, twin box-type track frames, and hydraulic automatic track adjustment; some spec listings reference a wider shoe option, so exact width varies by configuration/series and should be confirmed against the build sheet. Track tensioning and parking brake are hydraulically actuated as standard.
Cab and attachment guarding
Operator cab is built to meet falling-object protective structure (FOPS) requirements for mining and quarry duty. Attachment design keeps bucket and boom cylinders tucked within the structure's shadow rather than exposed, reducing damage risk from spillage and face contact during loading.
Lubrication support system
This shovel platform is commonly fitted with hydraulically driven, single-line automatic central lubrication for chassis and attachment pin points, with a separate line greasing the swing-ring open gear through a lube pinion. Whether this is standard or optional on this specific serial's build has not been confirmed from model-specific documentation - verify against the build sheet or with your dealer.

PC4000-6(S/N 08152) serial number reference
The ID/PIN plate lists model and serial number and is affixed to the machine per standard Komatsu factory practice; a Komatsu-branded plate or decal covers the stamped number. Exact plate placement on this size of mining shovel is not confirmed in accessible sources - check the machine's technical-data section or ask your dealer if it is not immediately visible. There is no 3-letter regional prefix to decode on this model - read the 5-digit serial directly (e.g. 08152) and match it against the factory manual cover range to confirm exact configuration.
| Prefix | Identifies | Notes |
|---|---|---|
| 08xxx | PC4000-6 hydraulic mining shovel, base -6 generation | No 3-letter alpha PIN prefix on this model. The -6 series factory manual is issued per discrete 5-digit serial number rather than a shared range block; this unit's manual is titled for S/N 08152 specifically (dated 2006, Komatsu Mining Germany GmbH). Neighboring individually-manualed units include 08155, 08170 and 08172. Fitted with the Komatsu SDA16V160, a 16-cylinder water-cooled diesel, turbocharged and aftercooled, rated near 1400 kW (1875 hp) at 1800 rpm. Built at the Komatsu Mining Germany plant in Dusseldorf (former O&K/Demag works). |
| 08199+ | PC4000-6 T2 block (later production) | confirm with dealer - a separate factory manual titled for the T2 configuration is issued starting at S/N 08199, pointing to a Tier 2 emissions engine update (SDA16V160E-2) within the same -6 model line. The exact break serial between the earlier engine and the T2 engine is not published in accessible sources; S/N 08152 predates this block. |
Frequently asked questions
What engine does the Komatsu PC4000-6(S/N 08152) use?
This unit runs a Komatsu SDA16V160, a 16-cylinder, water-cooled, turbocharged and aftercooled diesel rated near 1400 kW (1875 HP) at 1800 rpm. S/N 08152 falls in the early -6 production run, ahead of the factory's Tier 2 engine block (SDA16V160E-2) introduced around S/N 08199 and up, so confirm the exact engine variant against this unit's own dataplate.
What is the operating weight of the Komatsu PC4000-6?
Operating weight runs roughly 388-399 t (855,500-879,800 lb), varying with whether the machine carries the front-shovel or backhoe attachment and its counterweight configuration. Check the build sheet for this specific unit's fitted front end to get an exact figure.
What replaced the Komatsu PC4000-6?
Komatsu succeeded the PC4000-6 with the PC4000-11, introduced around 2018 with a Tier 4 Final SDA16V160E-3 engine, selective catalytic reduction, and a heavier operating-weight range of roughly 398-409 t. The -6 series itself had followed the original Tier 1 PC4000.
What PC4000-6(S/N 08152) owners discuss
What do owners and mechanics say about the PC4000-6 hydraulic system in daily use?
The four-circuit Hydropilot hydraulic layout, fed by four swash-plate pumps with a combined flow near 4140 L/min (1094 gal/min), gets consistent praise for control precision and lifting power when the oil stays clean. The recurring failure pattern reported for this shovel class is contamination-driven, not a pump or valve design flaw: sluggish cylinder response, overheating oil, pump noise and reduced breakout/crowd force show up well before any component actually wears out, and they trace back to dirty filters or degraded oil. Weeping rod seals on the boom, arm/stick and bucket or clam cylinders are the most reported leak point. The diaphragm-type accumulators in the pilot circuit store hydraulic pressure even with the engine off; bleed them down at the test socket before any hose or line work, and have your dealer verify correct discharge procedure before opening that circuit.
What undercarriage or wear patterns are typical for a shovel this size?
At this operating weight (388-399 t / 855,500-879,800 lb depending on shovel or backhoe front-end), the undercarriage relies on a large ground-contact surface area plus hardened track-link pin bores and hardened engaging faces to keep wear manageable. Track pad wear gets checked with a depth gauge against the base plate after cleaning off mud, since packed material can hide real wear. Aftermarket shops cast replacement shoes to higher hardness specifically because factory shoe and pad wear is the most repeated undercarriage complaint on this shovel class. Final drives, idlers, rollers, sprockets, and the swing/center joint are treated as scheduled-replacement items on units logging heavy mining hours, not run-to-failure parts.
Does the engine on this serial range have any known quirks compared to later PC4000-6 units?
S/N 08152 falls in the early PC4000-6 production run, ahead of the documented T2 manual break at S/N 08199 and up. The SDA16V160 fitted to this range is Komatsu's badge for the Cummins QSK60-based 16-cylinder engine in its first-generation fuel system: semi-electronic control with mechanical unit injectors (HPI), not a full common-rail system. Cummins has since moved its industrial QSK60 line entirely to the later common-rail (MCRS) fuel system, so owners of early units in this range should expect longer lead times sourcing HPI-specific injection components versus the newer common-rail parts. Units from roughly S/N 08199 up carry the SDA16V160E-2, a Tier 2-certified version of the same base engine; the exact serial where the fuel system itself changed isn't published, so confirm the fitted engine variant against this unit's own engine dataplate rather than assuming from serial number alone.
What electrical or sensor issues come up most for this generation of Komatsu mining shovel?
The PC4000-6 runs Komatsu's VHMS health-monitoring system into a cab touchscreen for engine data, fault codes and trending, alongside a Lincoln automatic lubrication system covering chassis grease points and the swing-ring open gear. Community troubleshooting for this era of Komatsu electronics points to wiring and grounding ahead of the sensors themselves: corroded connectors, chafed harness insulation and unstable charging-system voltage get blamed more often than a genuinely failed transducer when several unrelated fault codes appear together. With dozens of pressure and temperature sensors feeding VHMS on a machine this size, mechanics treat an intermittent single-sensor code as a validate-before-replace item - recheck the sensor and its connector under load first.
Are the swing drive and final drives a common wear point on the PC4000-6?
Yes. Swing motors, the center joint, and the travel final drives are flagged repeatedly as high-turnover supply items for this shovel class, alongside cooling-pack and radiator assemblies. Loss of swing or travel power paired with grinding or whining noise typically traces back to oil contamination, a low lubricant level, or bearing wear inside the reduction unit rather than the hydraulic motor itself. Because these are sealed, oil-lubricated assemblies, regular oil sampling on the swing and travel gearboxes is the main early-warning tool mechanics rely on for this platform.
What's the overall reliability reputation of the PC4000-6?
Owners describe it as durable and productive on a disciplined maintenance schedule rather than an inherently trouble-prone design - it's built for continuous mining duty, not intermittent use, and most reported problems trace back to deferred hydraulic filtration or lubrication rather than a chronic engineering defect in the -6 series itself. No widely reported design-specific failure mode is documented for this generation beyond the general contamination, seal-wear and wiring/grounding patterns common to large hydraulic mining shovels of this scale.
What should you check before buying a used PC4000-6, specifically one in the S/N 08152 range?
Confirm the exact serial against the factory manual block it falls under - S/N 08152 sits in the early production run, ahead of the T2/-E2 emissions update introduced around S/N 08199, and parts/service documentation is issued per discrete serial block rather than one blanket manual for the whole -6 series. Gauge track pad and pin-bore wear rather than relying on a visual pass. Pull VHMS trending and fault history if available and look for repeat sensor or grounding codes rather than a single isolated event. Inspect boom, stick, bucket and clam cylinder rod seals for weeping, and ask for hydraulic oil analysis history. Check hours against documented engine and main pump rebuild records, since a shovel this size is normally sold with at least partial component-life paperwork. Have your dealer verify the structural welds and pins on the boom-to-stick and stick-to-bucket/clam linkage for cracking before purchase - this is a safety-critical structural check that goes beyond a walk-around inspection.
