Komatsu PW100-1(S/N 1003-UP)
Maintenance schedule, common problems & OEM parts breakdown
The Komatsu PW100-1 (S/N 1003-UP) is a first-generation wheeled hydraulic excavator in the roughly 10.6-tonne (23,369 lb) operating weight class, built in the early 1980s for road-going, backhoe-style digging work on tires rather than tracks. Power comes from a Komatsu S4D105-5, a four-cylinder, naturally aspirated diesel with mechanical fuel injection and no electronic engine controls, rated in the class of roughly 55-68 kW (about 75-90 hp) gross depending on source and rating standard. Standard equipment includes 9.00-20 14PR tires and a general-purpose bucket around 0.56 cubic meters, with the machine folding down to roughly 6.97 x 3.49 x 3.71 m for transport. The S/N 1003-UP designation marks the initial production run of the PW100 nameplate, ahead of the later six-cylinder PW100-3 (S/N 1601-UP).
Across the PW100 nameplate, the biggest change after this first generation was a move from the four-cylinder S4D105-5 up to the six-cylinder Komatsu S6D95L-1 on the later PW100-3 (S/N 1601-UP), paired with a step up in operating weight class - a genuine engine-family change, not a running update. Exact end-of-production dates for the PW100-1 are thinly documented; available records place it in the early-to-mid 1980s without a firm closing year, which is typical for this vintage of European-market wheeled excavator. In the used and parts market today, the PW100-1 mainly turns up as an older fleet or collector machine valued for its simple, mechanically governed engine with no ECM to fail, and as a donor for axle, differential, swing drive, and engine components that have grown scarce as Komatsu's dealer support has shifted to later PW-series machines.

Servicing the PW100-1(S/N 1003-UP) beyond the schedule
Predictive Maintenance & Fluid Analysis
The PW100-1 predates onboard diagnostics, so fluid sampling is the main early-warning tool. Pull periodic samples from the S4D105-5 engine oil, axle differential oil, swing drive oil, and hydraulic tank to track wear metals, coolant contamination, and soot loading in this mechanically governed diesel. Watch injection pump and nozzle condition through fuel filter debris and exhaust smoke color, since no fault codes exist. Track hydraulic filter differential pressure by hand and log fuel consumption trends to catch injector or pump wear before it strands the machine.
Corrective & Common Repairs
Common failures on this generation center on the wheeled driveline: worn steering kingpins, leaking axle differential seals, and wheel-end bearing wear from road travel between sites. Expect hydraulic cylinder rod seal leaks on the boom, stick, and bucket circuits after decades of service, plus deteriorated rubber hoses on the naturally aspirated S4D105-5's fuel and cooling circuits. Starter motor and alternator brush wear is typical on mechanically governed engines this age. Steering linkage play and drive-shaft universal joint wear should be checked whenever the machine feels loose on the road.
Overhaul & Rebuild Points
At major overhaul, the S4D105-5 block, head, and injection pump are the core rebuild items; check cylinder compression and bore wear before committing to an in-frame kit. Axle differentials and final drives on the wheeled undercarriage wear internally from road use and warrant teardown inspection for gear and bearing wear at rebuild intervals. Swing drive and travel/transfer case gearing should be inspected alongside the hydraulic pump and main control valve for internal leakage. Given the machine's age, source rebuild kits and gaskets early since availability has narrowed.
Seasonal & Environment Servicing
Cold-weather starts on the naturally aspirated, mechanically governed S4D105-5 benefit from correct-viscosity engine oil and a fully charged battery, since there is no glow-plug or ECM-assisted cold-start logic to fall back on. Drain fuel tank water weekly in wet climates to protect the mechanical injection pump. In hot or dusty conditions, clean the radiator and oil cooler cores often and check axle and swing drive breathers for clogging. On the road-going wheeled chassis, check tire pressure and condition seasonally, since temperature swings affect the 9.00-20 tires' load rating.

PW100-1(S/N 1003-UP) attachments & work tools
Buckets
Factory GP bucket capacity is around 0.56 m3 (0.7 cu yd) heaped, matching this machine's roughly 10.6-tonne operating weight. For this 10-11 tonne wheeled-excavator class, GD (general-duty) buckets typically run about 0.3-0.6 m3 and HD/rock buckets about 0.2-0.45 m3 depending on width, with widths commonly in the 600-1000mm range. Most buckets on this class are pin-on; coupler-mounted buckets are common as a dealer-fit option rather than factory-standard.
Hydraulic hammers
This size class pairs with medium-duty breakers in roughly the 300-600 kg operating-weight class, the same class marketed for 10-16 tonne carriers such as this machine. Match hammer flow and working pressure to the excavator's stock single-circuit auxiliary plumbing; confirm actual pump output with a dealer before sizing a hammer.
Quick couplers
Pin-grab and wedge-style mechanical or hydraulic couplers sized to this excavator's bucket-pin class are the typical fitment, allowing buckets, breakers and grapples to swap without driving pins by hand. Factory-style quick hitches for this size range add positive locking and hose-burst protection as standard, with a low-profile design to limit breakout-force loss.
Thumbs/grapples
Main-pin-mounted hydraulic thumb kits are a common aftermarket fit for this size class, clamping material against the bucket for demolition, sorting and pick-up work. Dedicated grapple attachments are not well documented for this specific wheel-excavator model; if fitting one, size to the 10-11 tonne carrier class and confirm hydraulic circuit compatibility with the dealer.
Rippers
Single-shank rippers built for the 10-15 tonne excavator class fit this machine, mounting to the stick in place of the bucket on the same pin sizing. Typical units for this class use a thick shank (roughly 55-60mm) with about 750mm (30 in) of penetration depth, suited to hard-packed soil, frozen ground or light rock ripping.
Hydraulic-kit notes
This machine's auxiliary circuit is consistent with a medium-pressure, single-direction setup typical of this era of wheeled excavator rather than a factory two-way high-flow circuit. Tools needing high-flow two-way plumbing (mulchers, tiltrotators) generally require a dealer-fit auxiliary kit; confirm circuit type and flow before ordering flow-dependent tools.

PW100-1(S/N 1003-UP) serial number reference
The PW100-1 serial/PIN plate is riveted to the main frame, typically near the operator's cab or visible on the frame rail from ground level; the engine carries its own serial stamped on the block. Because this is an early-production wheeled excavator built before Komatsu's letter-prefix PIN era, the plate shows only the model designation plus a plain sequential number (1003 and up) — there is no 3-character letter code to decode on this range.
| Prefix | Identifies | Notes |
|---|---|---|
| 1003-UP (no letter PIN prefix) | PW100-1 base wheeled excavator series | Parts book covers this model as a single straight numeric serial block starting at 1003, with no 3-character letter PIN code ahead of the number. This matches early-1980s Komatsu practice, since the 17-character ISO PIN with letter-prefix codes on export machines did not become standard until decades later. Fitted with the S4D105-5 four-cylinder diesel (minor A/B running-change suffixes exist within the block but do not change the base engine designation). This is a distinct engine from the later PW100-3 (S/N 1601-UP) generation, which carries a six-cylinder S6D95L-1. A minor component-level running change (instrument panel) is documented partway through this serial block; treat the block as one continuous run unless a dealer parts lookup shows a spec change beyond that detail. |
Frequently asked questions
What engine powers the Komatsu PW100-1 (S/N 1003-UP)?
It uses a Komatsu S4D105-5, a four-cylinder, naturally aspirated diesel with mechanical fuel injection and no electronic engine controls. Published gross output for this engine class runs roughly 55-68 kW (about 75-90 hp), with figures varying slightly by source and rating standard.
What is the operating weight of the PW100-1?
Operating weight is approximately 10.6 tonnes (about 23,369 lb) in standard configuration, riding on 9.00-20 14PR tires.
What replaced the Komatsu PW100-1?
Within this model range, the PW100-1 (S/N 1003-UP) was succeeded by the PW100-3 (S/N 1601-UP), which switched to a six-cylinder Komatsu S6D95L-1 engine and a heavier operating weight class. Treat the two generations as separate machines when sourcing parts.
What PW100-1(S/N 1003-UP) owners discuss
What do operators and mechanics say about the hydraulic system on this machine?
Sluggish boom, arm, or bucket movement, rising oil temperature, and pump whine on a machine this age most often trace back to a worn main pump, tired spool valves, or contaminated fluid rather than one specific design fault. The most commonly reported leak points on a wheeled excavator of this type are the center hydraulic swivel (steering column) and the stabilizer leg cylinder seals — both usually show up as slow weeping rather than sudden failure, and both are seal-kit jobs rather than structural problems. If a stabilizer leg settles under load or a boom cylinder drifts while parked, have your dealer verify cylinder and holding-valve condition before returning the machine to service.
What engine quirks come up for the S4D105-5 in this machine?
The S4D105-5 is a mechanically governed, in-line-pump diesel with no electronic control, so reported issues trace to fuel quality and mechanical wear rather than sensors or software. Dirty or water-contaminated fuel is the most common cause of a stuck injector plunger, which shows up as rough running or fuel weeping from a single line rather than an even miss across all cylinders. Static injection timing that has drifted even slightly is a frequent cause of cold-start white smoke or, under load, black smoke and power loss on engines of this generation — a qualified injection-pump shop, not a parts swap, is the usual fix. Note this earlier four-cylinder engine is a different unit and generation from the six-cylinder engine used in the later version of this nameplate; timing and injection-pump service data don't carry over between them.
Any quirks about cold starting or exhaust smoke?
On mechanically governed diesels of this era, cold-start white smoke is usually condensation or slightly retarded injection timing rather than a failed part, and it should clear within a minute or two of warm-up. White smoke that persists well past warm-up, or heavy black smoke under load, points to injection timing or a worn plunger rather than the cold-start aid itself. Slow cranking or a weak cold-start aid is more often a battery or starter issue than an engine fault on machines this old, so check those first.
Are there known electrical or sensor problems on this machine?
This generation predates onboard electronics — there's no ECM, no diagnostic sensor network, and nothing to scan for fault codes. Reported electrical complaints on machines this age are basic: corroded connectors and ground points causing voltage drop, worn starter solenoids, and charging faults from a tired alternator or loose battery terminals. Chase these with a multimeter at the connectors and grounds first, and assume general wiring fatigue before suspecting a bigger fault.
What wear patterns are typical for the axles, steering, and tires?
This is a wheeled, not tracked, machine, so the equivalent wear points are the axle oscillation pivots, steering linkage, and tires rather than track chain and rollers. At roughly 10.6 t (23,400 lb) operating weight, worn oscillation pivots and uneven tire wear affect stability and steering feel more than on a lighter wheeled machine. Uneven or one-sided tire wear is a common clue to steering geometry or axle alignment trouble rather than the tires themselves being at fault, and oscillation pivots loosen with age and uneven-ground use. None of this is unique to this model — it's the general wear pattern expected on any wheeled excavator of this vintage.
What should I check when buying a used PW100-1 (S/N 1003-UP)?
Walk the tires for uneven wear as a steering/axle clue, check the center hydraulic swivel for leaks (a costly repair if worn), cycle every cylinder through full travel and watch for drift or chatter, and confirm the stabilizer legs hold under load without creeping down. Because this engine predates any electronic diagnostics, there are no fault codes to pull — a compression or leak-down check plus a look at the injection pump are the practical ways to gauge internal engine health. This is an early-production, low-volume serial range, so documentation and parts support are thin compared with later, more common machines; budget extra lead time for sourcing. Have your dealer or a qualified mechanic verify steering, brakes, and stabilizer lock function before purchase.
