The Komatsu WB93R-2 (S/N 93F20001-Up) is a compact loader-backhoe: a wheeled front loader and a rear backhoe on outriggers built onto one chassis, for utility digging, trenching, and material handling. This -2 generation manual covers the WB91R-2 and WB93R-2 side by side, with the WB93R-2 the larger-bucket, higher-capacity variant of the pair. It runs a naturally aspirated Komatsu S4D106-2 four-cylinder diesel with mechanical, non-electronic fuel injection, rated 73 kW (97.8 hp) net / 74.6 kW (100 hp) gross at 2200 rpm, through a full powershift transmission with four forward and four reverse gears reaching 40 km/h (24.9 mph). Standard operating weight is 7,500 kg (16,535 lb), rising to 8,580 kg (18,916 lb) in a maximum working, full-attachment configuration. Komatsu built the -2 generation from around 1999 into the mid-2000s, offering 2WD and 4WD drivelines and a choice of tires and stabilizer setups; it followed Komatsu's earlier -1 generation utility backhoe loader and was directly succeeded by the WB93R-5.

Beyond bucket size, the -2 generation differs from later Komatsu backhoe loaders mainly in control architecture: full mechanical engine governance and hydraulic-linkage control levers, not the electronic engine management later dash-series machines adopted. Komatsu's own product records show the line jumped straight from the -2 generation to the WB93R-5 in Europe, skipping intermediate dash numbers as the range was folded into Komatsu's global backhoe loader platform. In the used and parts market, that mechanical simplicity is the draw: no ECM to fault-code, and the S4D106 engine and axle/transmission components carry across several Komatsu utility machines of the same era, keeping parts and rebuild kits available well after new-unit production moved on to newer generations.

Komatsu WB93R-2(S/N 93F20001-Up) maintenance schedule

Service interval	Tasks
Every 50 h	Check engine oil and coolant level before starting each day; top off with the correct grade fluid. Grease all front loader and backhoe pivot pins and cylinder couplings, machine parked with the bucket resting on the ground and the backhoe boom fully extended. Check tire pressure and condition on both axles before daily operation. Check fan belt and A/C compressor belt deflection; adjust tension if outside spec. Check battery electrolyte level; top up with distilled water only. Check gauges, warning lights, and loader/backhoe control lever response before starting work.
Every 250 h	Check front axle differential and final-drive oil levels at the level plug. Check rear axle differential and final-drive oil levels at the level plug. Check transmission (torque converter) oil level with the engine running at operating temperature; top off to the max mark. Re-check fan belt and A/C compressor belt tension. Check wheel nut torque on both front and rear wheels against spec.
Every 500 h	Change engine oil (EO-series) and replace the engine oil filter. Replace the hydraulic system oil filter cartridge. Replace the fuel filter and bleed the fuel circuit. Drain water and sediment from the fuel tank. Drain condensate from the hydraulic oil tank on machines running biodegradable HEES hydraulic oil. Clean the radiator and A/C condenser fins with compressed air or low-pressure water.
Every 1,000 h	Drain and refill front axle differential and final-drive oil (AXO axle oil). Drain and refill rear axle differential and final-drive oil (AXO axle oil). Drain the transmission oil, replace the transmission filter, and refill with TO-series oil to spec. Have the dealer check and adjust engine valve clearance; special tools are required.
Every 2,000 h	Change the hydraulic system oil (HO-series) and clean the suction filter screen. Drain and refill engine coolant (AF-NAC coolant). Change brake system fluid and bleed the brakes. Have the alternator and starter inspected by a Komatsu dealer. Have the A/C refrigerant charge checked by qualified personnel.
Every 4,000 h	Inspect loader and backhoe pivot pins and bushings for play; replace worn bushings before it affects boom control. Have the mechanical injection pump and injectors bench-tested and serviced by a dealer. Inspect the powershift transmission clutch packs and torque converter for slippage or overheating history; rebuild as needed. Reseal loader and backhoe hydraulic cylinders showing rod wear or seepage. Inspect king pin and steering-axle wear on the 4WD front axle.

Servicing the WB93R-2(S/N 93F20001-Up) beyond the schedule

Predictive Maintenance & Fluid Analysis

Sample the EO-series engine oil at every 500-hour change since the naturally aspirated S4D106-2 runs mechanical injection with no ECM to flag wear electronically. Send HO-series hydraulic oil for lab analysis given the single tank and circuit that powers the loader arms, backhoe boom, steering, and outriggers; contamination shows up as slow cylinder drift before it shows on a dipstick. Check front and rear axle AXO oil for metal fines at every 250-hour level check, and track coolant condition since there is no digital overheat warning beyond the temperature gauge.

Corrective & Common Repairs

Expect wear at the loader and backhoe pin and bushing joints first. Constant articulation under outrigger-stabilized digging loosens dipper, boom, and bucket linkages faster than the loader end. The full powershift 4WD transmission takes repeated forward/reverse shuttling in loader work; watch for clutch-pack slip or delayed engagement. Check king pin and steering-axle wear on the front axle, a common wear point here. Because the S4D106-2 has no self-diagnostic codes, injection pump and injector faults show up as rough running or smoke, not a warning light, and need mechanical troubleshooting.

Overhaul & Rebuild Points

Reseal loader arm, bucket, backhoe boom, dipper, and outrigger cylinders once rod wear or seepage appears; the shared hydraulic circuit means a failing seal on one end affects pressure at the other. Rebuild the powershift transmission and torque converter when high hours bring slippage or overheating. Overhaul front and rear axle differentials and final drives together, since both wear from the same duty cycle. On the naturally aspirated S4D106-2, injection pump timing must be reset by a dealer with the mechanical calibration tools this engine requires, not a laptop.

Seasonal & Environment Servicing

Check AF-NAC coolant concentration before cold weather; the naturally aspirated S4D106-2 has no electronic cold-start assist beyond glow plugs, so a weak battery or thin coolant mix hurts starting fast. Confirm HO-series hydraulic oil grade matches the season, or step down to the wide-range multigrade grade for extreme cold. Clean the radiator and A/C condenser before summer; outrigger-stabilized digging keeps the hydraulic pump under continuous load and heat builds fast. In wet or muddy conditions, grease loader and backhoe pins more often than the 10-hour interval calls for.

WB93R-2(S/N 93F20001-Up) attachments & work tools

Front loader buckets

Standard general-purpose bucket holds about 1.03 m3 (1.35 yd3) at roughly 2.32 m (91 in) width, with breakout force near 64 kN (14,350 lbf). A 4-in-1 (multi-purpose) bucket is offered as a factory option, using its own hydraulic cylinder for clamshell, dozing, and grab functions.

Pallet forks

Fork tines mount to the front loader as optional material-handling equipment, either fitted to the 4-in-1 bucket frame or carried on the front quick-attach. Rated capacity runs about 2.0-2.5 t depending on the fork set fitted; actual safe working load follows the rating stamped on the forks themselves.

Front quick coupler / mounting

A mechanical quick-coupling hitch is available as an option for fast front bucket and tool changes without pulling pins. Where not fitted, the loader bucket and 4-in-1 tool attach with conventional pin-on linkage.

Rear backhoe buckets

Standard digging bucket works with the standard dipperstick to about 4.95 m (16.25 ft) digging depth and 5.55 m (18.2 ft) max reach. Backhoe bucket width varies by job, from narrow trenching buckets to wider general-purpose buckets, matched to the pin-on backhoe linkage; a hydraulic quick coupler is offered as an option on this class for faster bucket swaps.

Extendable dipperstick

An extending (telescoping) dipperstick option is documented for this digging depth class, increasing reach to roughly 6.1 m (20 ft) versus the standard arm. Useful for deeper utility trenching without stepping up to a larger base machine.

Hydraulic hammer / breaker

The backhoe dipper accepts a pin-on hydraulic hammer sized for carriers in this operating-weight class (roughly 7.5-8.6 t). The breaker runs off the backhoe's auxiliary hydraulic circuit; flow and pressure must be matched to the specific hammer make and model, so confirm compatibility with the breaker manufacturer or a dealer before fitting.

Auger and other rotary tools

No auger fitment is documented specifically for this serial range in the factory literature reviewed. Where offered on comparable Komatsu loader-backhoes, augers and similar rotary or grapple tools run off the same backhoe auxiliary circuit as the hammer; verify exact compatibility with a dealer before ordering, as this varies by configuration/series.

Outriggers and backhoe positioning

Rear outrigger stabilizer legs are standard equipment for backhoe digging stability. A hydraulic backhoe side-shift frame is available as an option in this size class, letting the boom swing off-center for digging alongside walls or trenches without repositioning the machine.

WB93R-2(S/N 93F20001-Up) serial number reference

The PIN/serial plate is mounted behind the brake pedal on the cab firewall, inside the operator's station. Reading the number: the first two digits identify the machine size class (93 for the WB93 platform), the letter that follows is the build-series code (F for this generation), and the digits after that are the running production serial number, which climbs through the production run while the 93F prefix itself stays fixed.

Prefix	Identifies	Notes
93F	WB93R-2 loader-backhoe (Komatsu Utility Europe, Italy-built), 1999-2005 production	Only PIN prefix documented for this loader-backhoe family. Running serial number starts at 93F20001 and steps through further factory running-change points later in the build run (around 93F21638, 93F23075, 93F23453, and 93F25184) -- each is a parts/running update captured in its own factory parts-catalog printing, not a separate prefix or model. Fitted with the naturally aspirated 4-cylinder Komatsu S4D106-2 diesel, about 73 kW (97.8 hp) net. Operating weight runs roughly 7.5-8.58 t depending on configuration (2WD/4WD, cab or canopy, counterweight). Exact cutoff reason for each running-change point is not spelled out in available literature -- confirm with a dealer if pinpointing an exact build date.

Frequently asked questions

What engine does the Komatsu WB93R-2 (S/N 93F20001-Up) use?

A naturally aspirated Komatsu S4D106-2 four-cylinder diesel with mechanical fuel injection - no turbocharger and no electronic engine control on this serial range. It is rated 73 kW (97.8 hp) net / 74.6 kW (100 hp) gross at 2200 rpm.

What is the operating weight of the WB93R-2 (S/N 93F20001-Up)?

Standard operating weight is 7,500 kg (16,535 lb). In a maximum working, full-attachment configuration it reaches 8,580 kg (18,916 lb). Exact figure varies by 2WD/4WD driveline, tires, and ballast.

What replaced the Komatsu WB93R-2?

Komatsu's own product records show the WB93R-2 was succeeded directly by the WB93R-5, which replaced this -2 generation platform in Komatsu's European backhoe loader lineup.

What WB93R-2(S/N 93F20001-Up) owners discuss

What engine powers the Komatsu WB93R-2 (S/N 93F20001-Up), and what do owners flag about it?

This serial range runs a naturally aspirated Komatsu S4D106-2 inline-4 diesel, a Yanmar-derived block of roughly 4.4 liter displacement, with fully mechanical fuel injection and no turbocharger or electronic engine control. Rated output is 74.6 kW (100 hp) gross and 73 kW (97.8 hp) net at 2200 rpm; check the engine nameplate on the actual unit against the serial range before trusting any single spec chart. Owners and independent shops working on this generation stress keeping oil clean and changed on schedule, since the mechanical injection pump wears faster on neglected or contaminated oil and there is no ECM to flag the problem early. Some smoke on a cold start is normal until fully warmed through; smoke that persists at operating temperature points to worn injectors or an out-of-time injection pump. Later WB93R generations (WB93R-5 and newer) moved to different Komatsu engine families, so parts and service notes for those don't carry over to this S/N range.

What do mechanics say about the loader and backhoe hydraulics on this machine?

The WB93R-2 runs separate control valve blocks for the loader (shovel) end and the backhoe end, fed off the main hydraulic pump, with a factory-set relief/safety valve that Komatsu documentation warns against adjusting in the field. A recurring theme in owner troubleshooting: after hose work on the backhoe side, the stabilizers move but won't lift the machine off the ground even though the rest of the hydraulics respond normally. That symptom traces back to air trapped in the circuit after a hose swap far more often than a failed pump, so bleed the lines, recheck fluid level and cleanliness, and confirm hose routing and fittings are fully seated before chasing the pump or valve block. On the loader end, slow or spongy bucket response usually points to a tired pump or a sticking spool rather than a worn pump outright. Have your dealer verify relief valve pressures and pump output on a flow-test bench before condemning or rebuilding any hydraulic component.

How does the powershift transmission and 4WD front axle hold up in real-world use?

Power reaches the wheels through a full powershift transmission with a torque converter and power shuttle for forward and reverse, feeding a 4WD front axle. On this class of loader-backhoe, the front axle mount and its bushings take more punishment than the rest of the driveline, because engaging 4WD adds torque reaction that the mount absorbs; expect that mount to need attention well before the axle housing itself does, especially on machines run in 4WD on hard or paved surfaces. Powershift clutch packs and the torque converter are generally durable when fluid and filter service stay current, but a machine run low on transmission fluid or on old fluid shows shift shock, slipping, or delayed engagement long before the internal components are actually worn out. Fluid condition and change history matter more to this transmission's lifespan than raw hour count.

Where does this machine wear first, and what should an owner watch on the loader arms, backhoe, and stabilizers?

Wear shows up first at the pin-and-bushing joints: loader arm pivots, bucket linkage, and the backhoe boom, dipper, and bucket pins all take repeated shock loading and develop play with hours. Stabilizer (outrigger) cylinders are a known weep point; seals that sat unpressurized while parked can seep slightly and often reseat once the machine goes back to work, but a stabilizer that leaks down under load while digging is a seal or check-valve fault, not normal weeping. Boom and dipper cylinder rods working in rocky or abrasive spoil are prone to scoring from flying debris, and a scored rod keeps leaking past new seals until the rod itself is polished or replaced, so inspect rod surfaces closely on any machine that has dug in rock, not just the seals. Tires and bucket-edge wear are otherwise straightforward wear items, not warning signs of anything deeper.

What electrical or sensor issues come up on this generation of machine?

Electrical complaints on machines of this age center on connector and harness corrosion rather than outright component failure. Intermittent gauge readings, a coolant-temperature warning with a normal-reading gauge, or a warning light with no matching symptom usually trace back to a corroded or loose connector pin in the sensor harness, not a bad sensor or a broken wire run. Because the dash on this generation relies on a handful of key sensors (coolant temperature, oil pressure, charge) feeding a simple warning cluster, one flaky connector can set off what looks like several faults at once. Cleaning and dielectric-greasing the harness connectors at the engine and dash bulkhead as routine maintenance heads off most of these false alarms before they start.

What should a buyer check before purchasing a used WB93R-2 (S/N 93F20001-Up)?

Confirm the serial plate actually falls in the 93F20001-Up range before relying on any parts or spec reference, since Komatsu revised parts and specs partway through this model's production run and a mismatched parts book means guesswork on service. Pull maintenance records for engine oil and transmission fluid change intervals, since both the mechanical injection pump and the powershift clutches are sensitive to neglected fluid. Cycle every hydraulic function under load, loader raise/lower/tilt, backhoe swing/boom/dipper/bucket, and both stabilizers, and watch for drift, slow response, or a stabilizer that won't hold the machine off the ground. Check every loader and backhoe pin/bushing joint for play, inspect the front axle mount and kingpins for wear (worse if the machine saw regular 4WD use on hard surfaces), look for oil weeping or exhaust smoke under load that could point to worn injectors or an injection pump needing service, and check exposed cylinder rods for scoring or pitting. Have your dealer verify hydraulic relief valve settings and stabilizer/backhoe function on a full pressure test before finalizing the purchase, since the backhoe and stabilizer hydraulics are the main safety-critical system on this machine.
