Komatsu WF550-3D(S/N 50001-UP)
Maintenance schedule, common problems & OEM parts breakdown
The Komatsu WF550-3D (S/N 50001-UP) is a wheel-type landfill/waste compactor, the loader-chassis member of Komatsu's WF-series waste-compaction line: it carries a bucket on its own lift-arm linkage rather than a push blade. It runs a Komatsu SA6D140E (also catalogued S6D140E) turbocharged, aftercooled inline-six diesel rated about 235 kW (315-320 PS/hp) at 2,100 rpm, driving a full powershift transmission with four forward and four reverse speeds through running gear shared with the era's WA500-3 wheel loader and WD500-3 wheel dozer platform. Operating weight runs roughly 35.1-35.5 t (77,382-78,264 lb), varying by configuration. Factory records place this WF550-3 generation in production around 2000-2003. It sits above the smaller WF450-3 (about 26 t, 194 kW) in Komatsu's compactor lineup, and shares its production generation with dozer-blade siblings badged WF550T-3, WF550T-3A, and a Hanomag-market WF550T-3D build, plus an A-suffix WF550A-3 variant catalogued separately in factory documentation. This S/N 50001-UP block is the parts-book serial range specific to the loader-type WF550-3D build.
Komatsu's WF-series generations track the mainstream wheel-loader and wheel-dozer platforms they are built from rather than following independent compactor development: earlier compactors in this family carried dash-1 badging (WF450T-1/-1A), and the generation covered here moved the compactor line onto the same driveline generation as the WA500-3/WD500-3 machines, so many wear parts, including hydraulic pumps, transmission components, and axle parts, cross-reference across the whole family instead of being compactor-unique. Komatsu does not carry a direct WF-series successor forward in North America today; its current waste-handling lineup leans on adapted dozers, excavators, wheel loaders, and trucks rather than a dedicated purpose-built compactor model. That makes surviving WF550-3D and WF550T-3 units a durable niche in the used and parts market: buyers get WA500-3-family parts commonality for driveline support, while dedicated landfill-compactor wear parts, chiefly the compaction-wheel cleats and drum hardfacing, still require specialty sourcing.

Servicing the WF550-3D(S/N 50001-UP) beyond the schedule
Predictive Maintenance & Fluid Analysis
Pull engine oil, transmission/torque-converter oil, axle oil, and hydraulic-tank samples on a set interval rather than only at scheduled changes; landfill duty pushes contamination and heat-cycling into the SA6D140E and powershift driveline faster than typical earthmoving hours. Trend coolant and hydraulic temperatures against cooler-core cleanliness rather than hour meter alone. Track compaction-wheel cleat and hardfacing wear on all four drums separately, since front and rear wear at different rates. Watch pressure-switch and wiring-connector readings for early corrosion signs in this environment.
Corrective & Common Repairs
Expect hydraulic hose and fitting leaks around the drum-arm and articulation-joint routing from constant flex and abrasive exposure; replace on condition rather than waiting for failure. Reweld or swap bolt-on cleat tips on the compaction drums once hardfacing rounds off, since packed refuse between worn cleats kills traction and accelerates further wear. Clear coolant and hydraulic-oil-cooler cores of ash and plastic film every shift; skipped blow-downs are the leading cause of high-temperature complaints on this driveline. Clean and dielectric-grease wiring connectors and pressure switches to cut false warning-lamp trips.
Overhaul & Rebuild Points
At major overhaul, inspect the articulation and oscillation center-pin bushings for play, given this compactor's loader-based chassis carries constant torsional load working nose-into-the-face. Check the frame, drum arms, and mounting welds for cracking before reusing them, since these are safety-critical structural points on a 35-tonne-class machine. Rebuild the powershift transmission and torque converter on the SA6D140E driveline as a set with axle/final-drive components sharing the WA500-3-family running gear. Full hardfacing rebuild or drum replacement is normal shop work once cleats round off past weld-repair limits.
Seasonal & Environment Servicing
Switch engine oil viscosity and diesel fuel grade for cold-start service below roughly 0°C (32°F), and set coolant concentration to the coldest expected ambient per the mix chart. In hot or dusty landfill conditions, increase radiator and hydraulic-cooler blow-down frequency beyond the standard interval, since fine ash and windblown plastic film pack the cores faster than normal earthmoving dust. Confirm cab pressurization and filtration are intact for operator air quality on an active tipping face, and verify any fire-suppression system is charged and functional each season.

WF550-3D(S/N 50001-UP) fault codes & troubleshooting
| Code | Meaning | Likely cause | What to do |
|---|---|---|---|
| E01 | Lowest-tier action code. A caution message appears on the character display; no buzzer. | A wide range of minor deviations can trip this tier — trend toward high temperature, low fluid level, or a sensor reading outside normal range on the engine, torque converter, or hydraulic circuit. | Note the message content, continue work if safe, and plan inspection or servicing of the flagged system at the next stop. |
| E02 | Mid-tier action code. Central warning lamp lights and the buzzer sounds intermittently along with the display message. | A more serious fault than E01 in the same group of systems — engine, torque converter/hydraulic circuit, or an electrical/control circuit supplying them. | Stop work as soon as it is safe, read the displayed message, and inspect the indicated system before resuming. |
| E03 | Highest-tier action code. Central warning lamp and continuous buzzer signal a serious fault. | Severe overheating, critical loss of oil pressure, or a major electrical/control fault that risks component damage if operation continues. | Stop the machine immediately, shut down the engine, and check the failure content on the display before any further operation. |
| AA10NX | Air cleaner (intake air filter) restriction/clogging warning. | Dirty or clogged air filter element, or a blocked intake duct, raising intake restriction beyond the allowed limit. | Stop the engine, inspect and clean or replace the air filter element, and check the restriction indicator before restarting. |
| AB00KE | Charging system voltage low or missing. | Worn or failing alternator, loose or slipping drive belt, corroded wiring/connections, or a weak or failing battery. | Check alternator output, belt condition and tension, and battery/wiring connections; charge or replace the battery as needed. |
| Coolant temperature caution/warning lamp | Engine coolant temperature above normal operating range. | Low coolant level, debris-clogged radiator core, failed cooling fan or fan drive, or a stuck thermostat. | Reduce load and idle to cool, then check coolant level and radiator core for blockage; inspect the fan drive before returning to full duty. |
| Torque converter/hydraulic oil temperature caution/warning lamp | Torque converter or hydraulic oil temperature above normal operating range. | Low torque converter/hydraulic oil level, clogged oil cooler fins, or sustained heavy load/converter stall generating excess heat. | Reduce load, idle to allow cooling, and check oil level and cooler core for blockage before resuming normal operation. |
| Engine oil pressure caution/warning lamp | Engine oil pressure below the minimum allowed threshold. | Low engine oil level, clogged oil filter, worn oil pump, or a faulty oil pressure sensor/switch. | Shut down the engine immediately, check oil level and look for leaks, and inspect the filter and pressure sensor before restarting. |

WF550-3D(S/N 50001-UP) attachments & work tools
Front loading tool
This loader-type compactor carries a wheel-loader-style bucket on the machine's own loader linkage rather than a straight dozer blade; the dozer-type sibling in this line uses a push blade instead. Bucket sizing follows the general-purpose bracket typical for this loader weight class, roughly 4.3-5.5 m3 (5.6-7.2 yd3), and pins directly to the lift arms.
Compaction wheels
Front and rear road wheels are replaced by sealed, spiked steel compaction wheels that crush and knead refuse as the machine tracks over it. Scraper bars run alongside each wheel to clear compacted waste from between the tips and keep the tread clean.
Wheel tips / wear points
Compaction-wheel tips are bolt-on and field-replaceable rather than integral to the wheel body. Tip styles used across this compactor weight class range from aggressive paddle-type points for traction in loose refuse to broader flat-face spikes for side-slope stability, with combination and diamond patterns offered for longer wear life; worn tips are typically refurbished or swapped rather than replacing the whole wheel.
Mounting / coupler system
The bucket pins on to the loader linkage in the standard way; no quick-hitch is fitted as a rule on this compactor. The large-wheel-loader platform this chassis shares offers wedge-type hydraulic quick couplers for fast changes between buckets, forks, and grapples, but landfill units are normally run with one dedicated waste bucket rather than swapped often.
Hydraulic kit
Bucket lift and tilt run off the machine's own loader hydraulic circuit. No separate auxiliary hydraulic kit is needed to run the standard waste bucket, unlike demountable excavator-style tools.
Factory guarding & cab configuration
Factory configuration for this compactor line includes underbody bodyguard plating and sealed axle housings to keep waste debris and leachate out of the driveline. Cab is ROPS-rated as standard; heavier screening or guarding for cab glazing is common on landfill duty in this class but should be confirmed against the specific serial-range option list, varies by configuration.

WF550-3D(S/N 50001-UP) serial number reference
On this wheel-type compactor the product identification (PIN) plate is riveted to the main frame, typically near the front frame or articulation joint, with the number also stamped into the frame steel as a backup. The serial reads as a plain sequential number rather than a modern multi-letter worldwide PIN: the leading digits (500xx) identify the WF550-3D production block for this parts book, and the trailing digits are the sequential unit count within that block.
| Prefix | Identifies | Notes |
|---|---|---|
| 500 | WF550-3D, S/N 50001-UP | Wheel-type landfill/waste compactor, roughly 35.5 t operating weight, built on the same running gear as the WA500-3 wheel loader and WD500-3 wheel dozer platform (shared axles, transmission and hydraulic pump listings across factory parts books). Fitted with the Komatsu S6D140E diesel (arrangement S6D140E-2D-6 for this parts book, engine itself carries its own S/N block separate from the machine serial), rated about 235 kW (315-320 PS/hp) at 2100 rpm, driving a full powershift transmission with 4 forward/4 reverse speeds, top speed around 20 km/h (12.5 mph). Serial block starts at 50001 and runs upward for this dash-suffix parts book; component-level running changes occur at a few points inside the block, but no separate dash-suffix break was found. Confirm exact build year and any mid-run running changes with your dealer using the full PIN. |
Frequently asked questions
What engine does the Komatsu WF550-3D (S/N 50001-UP) use?
A Komatsu SA6D140E, also catalogued as S6D140E: a turbocharged, aftercooled inline-six diesel rated about 235 kW (315-320 PS/hp) at 2,100 rpm. It is the same engine family used in the era's WA500-3 wheel loader and WD500-3 wheel dozer, the platform this compactor's chassis and driveline are built from.
What is the operating weight of the Komatsu WF550-3D (S/N 50001-UP)?
Roughly 35.1-35.5 t (77,382-78,264 lb), varying by configuration and options within the WF550-3 compactor line. Confirm exact weight against the specific unit's option list before transport or load-rating decisions.
What replaced the Komatsu WF550-3D landfill compactor?
Komatsu did not carry a direct WF-series successor forward in North America; its current waste-handling lineup leans on adapted dozers, excavators, wheel loaders, and trucks rather than a dedicated purpose-built compactor model. Used WF550-3D and WF550T-3 units remain in service today and are typically replaced in the field by other manufacturers' purpose-built landfill compactors when retired.
What WF550-3D(S/N 50001-UP) owners discuss
What do operators say about the WF550-3D's powertrain in day-to-day service?
The WF550-3D runs a turbocharged, aftercooled Komatsu SA6D140E diesel rated around 235 kW (320 PS) at 2,100 rpm, paired with a full powershift transmission with multiple forward and reverse ranges. That engine and much of the driveline carries over from the era's Komatsu wheel-loader and dozer lines, so it is a well-proven package with wide parts and service support even though compactor-specific units sit at dealers less often. Because the machine works nose-into-the-face constantly rather than traveling like a loader, expect harder-than-typical duty on the torque converter and driveline joints for the hours on the clock. Trend oil-sample data rather than trusting the hour meter alone on a used unit.
What hydraulic behaviors or complaints come up with this compactor?
The hydraulic circuit shares its design lineage with the period wheel-loader platform this compactor is built from. In landfill duty the main hydraulic complaint is contamination: fine ash, dust, and leachate residue work into breathers and fill points faster than on a clean earthmoving site, and that accelerates pump and valve wear if filters and fluid aren't serviced on a tightened interval rather than the standard one. Hose and fitting leaks around the drum-arm and articulation-joint routing also come up as a recurring wear point, driven by constant flex and abrasive exposure rather than any design flaw.
What wear pattern shows up on the wheels, and how much attention do they need?
All four wheels are solid steel drums with hardfaced cleats and no rubber, so there is no track-style undercarriage to watch, but the drums themselves are the wear item. Front and rear drums wear unevenly because the front set does most of the tearing and shredding work against the tipping face while the rear set trails behind, so each end needs checking on its own rather than assuming even wear. Cleat tips lose their hardfacing and round off with hours, and if the waste is wet or sticky the gaps between cleats pack solid, which kills traction, the machine rides up on packed material instead of biting in, and operators adding throttle or wheel spin to compensate only wears the cleats faster. Routine cleaning and rebuild-welding of cleats before they round off completely is the standard fix cited across this class of compactor generally, not a Komatsu-specific trait.
Is there a recurring engine or cooling quirk tied to running this machine on a landfill face?
The recurring theme is cooling-package fouling rather than any inherent engine defect. Landfill air carries plastic film, ash, and fine debris that packs into the radiator and hydraulic-oil-cooler cores far faster than typical earthmoving dust. Komatsu's own literature for this compactor line calls out easy cooler-grill access as a feature, which reflects how often that screen needs clearing in the field. Skipping a shift-by-shift blow-down of the cooling package is the most commonly cited cause of high coolant or hydraulic-oil temperature complaints on these machines.
What electrical or sensor issues are commonly reported on this machine?
The charging system, wiring, and the pressure switches that monitor the transmission and hydraulic circuits sit in a corrosive landfill-gas, moisture, and constant-vibration environment, and that combination is the common thread behind reported electrical faults. Corroded connectors and failed pressure switches triggering false warning lights or hard-start conditions come up more often than any core wiring defect in the machine itself. A dielectric-grease and connector-cleaning pass at each service interval is the usual preventive step mentioned for this duty cycle.
Is fire risk a particular concern with this machine, and what do operators do about it?
Yes. Waste-handling and landfill machines as a class carry materially higher fire risk than typical earthmoving equipment because combustible debris collects against hot engine-bay and exhaust components during normal work. Operators commonly add or specify a fire-suppression system for this duty even where one is not standard equipment, and stress keeping the engine compartment and cooler package clear of packed debris as the first line of defense. Have your dealer or a certified fire-suppression installer verify that any suppression system on a used unit is present, charged, and current on inspection before putting the machine into landfill service.
What should a buyer check before purchasing a used WF550-3D(S/N 50001-UP)?
Inspect cleat and hardfacing wear on all four drums separately and look for cracked or bent cleats, then check the drum arms and surrounding frame for cracking rather than judging the wheels alone. Check the articulation and oscillation joint and center pin for play, given the loader-based chassis this compactor is built on. Pull a hydraulic fluid sample and check filters and breathers for contamination consistent with landfill service, and review engine maintenance records for turbocharger and fuel-system service alongside a check for excess blow-by or smoke on start and under load. Inspect the radiator and hydraulic-oil-cooler cores for packed debris or corrosion, and ask whether the cooling package has actually been blown out on a routine schedule rather than only at major services. Check wiring-harness connectors and pressure switches for corrosion and confirm every instrument warning functions, and verify cab pressurization/filtration and any fire-suppression equipment are present and working. Have your dealer verify structural integrity of the frame, drum arms, and articulation joint, and confirm the hydraulic and braking systems are sound, before purchase, since these are safety-critical items on a machine this size.
