Komatsu 245(S/N 24500007-Up)
Maintenance schedule, common problems & OEM parts breakdown
The Komatsu 245 (S/N 24500007-Up) is a compact mini hydraulic excavator from Komatsu's small-excavator range, but unlike the Japan-built PC-series it carries no alpha PIN prefix and was built in Italy by FAI (Fabbrica Attrezzature Industriali) of Este and Noventa Vicentina. FAI began building Komatsu mini excavators under license in 1988, Komatsu took a shareholding stake in 1989, and Komatsu assumed full ownership in 1995, renaming the operation FKI FAI Komatsu SpA and later Komatsu Italia Manufacturing. No engine make, operating weight, or dimensional spec is publicly documented for this exact serial range; the machine sits in the mechanically-governed diesel era with no ECM, consistent with a small excavator built before Komatsu's electronic PC-series controls arrived. Exact production years for this specific serial block are not published, and the line sat alongside sibling bare-numbered models such as 212, 222, 230, and 235 offered in the same era, typically in a standard mono-boom configuration with canopy or cab options.
Across this bare-numbered Komatsu 2xx family, the main change over time was administrative rather than mechanical: Komatsu's move from a licensed and shareholder relationship with FAI to full ownership shifted production toward the alpha-prefix PIN and PC-series naming scheme that eventually replaced this lineup. That transition is also why so little factory documentation survives for a specific serial range like 24500007-Up outside dealer archives. In today's used and parts market, these machines matter mainly as inexpensive, tight-access compact excavators for owner-operators, with individual wear parts such as starters, water pumps, and drive sprockets cross-referenced against related small Komatsu excavator models. That cross-reference proves a shared small-excavator parts platform, not a shared engine or fluid spec, so buyers and parts sourcers should confirm machine identity against the physical serial plate and engine tag rather than assuming PC-series data applies.

Servicing the 245(S/N 24500007-Up) beyond the schedule
Predictive Maintenance & Fluid Analysis
The 245 (S/N 24500007-Up) runs a mechanically-governed diesel with no ECM or diagnostic display, so fluid sampling is the main early-warning tool available on this FAI-built platform. Pull engine oil, hydraulic oil, and final-drive and swing-gear oil samples at each filter change and watch for metal fines, water intrusion, or fuel dilution rather than waiting for a warning lamp. Because exact fluid specs for this serial range are not published, match viscosity and grade to climate and confirm with your dealer before topping off.
Corrective & Common Repairs
Most corrective work on this Italy-built mini excavator centers on wear items shared across the FAI-era small-excavator platform: starter motor drag, glow-plug and preheat circuit faults on cold starts, and pump whine or delayed cylinder response as seals and the hydraulic pump age. Chase electrical faults with a multimeter at the battery, starter, and alternator before assuming a sensor fault, since none exists. Pressure-test the hydraulic circuit and inspect cylinder rod seals before condemning the pump on a machine with sluggish boom or arm response.
Overhaul & Rebuild Points
When rebuild time comes on the 245 (S/N 24500007-Up), focus on the mechanical injection pump and governor linkage, swing bearing and pinion backlash, and final-drive travel motor internals, the components that carry this machine's working life on a pre-electronic platform. Undercarriage teardown should measure pin, bushing, and sprocket wear against limits rather than visual judgment alone. Because this line sits outside Komatsu's mainline PC-series parts network, source rebuild kits through a FAI or Komatsu Italia-lineage dealer and confirm fitment before ordering.
Seasonal & Environment Servicing
Cold-weather starts are the main seasonal risk on this mechanically-governed diesel: verify glow-plug and preheat circuit operation, battery state, and fuel rated for the season before relying on it in freezing conditions. In hot or dusty environments, check radiator and oil cooler fins for packed debris and clean them to protect the mechanical injection pump and hydraulic system from heat soak. Drain fuel-tank and water-separator sediment more often in humid storage conditions, and re-grease all boom, arm, and swing pivot pins after extended idle periods or wash-downs.

245(S/N 24500007-Up) attachments & work tools
Buckets
No verifiable bucket capacity range, pin diameter, or width data is published for this exact serial range. General-purpose, heavy-duty, and rock bucket lines exist across the Komatsu excavator range in this class, but sizing must be confirmed with a dealer against boom/arm and pin geometry for this specific machine.
Hydraulic hammers
No documented breaker weight class or hydraulic circuit spec ties to this serial range. Breaker sizing on excavators in this size class is normally matched by operating weight and hydraulic flow, but no source confirms which class applies here.
Quick couplers
No source confirms a specific coupler type (pin-grab or wedge/hydraulic) fitted to this machine. Coupler choice depends on stick pin diameter and spacing, which are not documented for this serial range.
Thumbs/grapples
No published fitment data for hydraulic or mechanical thumbs or grapples on this serial range. Sizing depends on arm and pin dimensions not found in available documentation.
Rippers
No documented ripper attachment or shank spec for this machine.
Hydraulic-kit notes
No verified auxiliary hydraulic circuit, flow, or pressure spec (medium-pressure vs high-flow) is documented for this serial range. Any attachment circuit requirement should be confirmed against the machine's actual hydraulic pump output and valve configuration with a dealer.

245(S/N 24500007-Up) serial number reference
On this model the PIN/serial plate is stamped on the front frame, generally between the two hydraulic arms near the boom mount, with a small Komatsu ID decal placed over or beside the stamping — the standard plate placement used across Komatsu's Italy-built mini-excavator line. Because this model has no 3-letter alpha prefix, read the plate as a plain digit string: the leading digits repeat the model number (245) and the remaining digits are the production sequence number, so "24500007-Up" marks the start of that sequence for this catalog listing.
| Prefix | Identifies | Notes |
|---|---|---|
| 245 (no 3-letter alpha prefix) | 245(S/N 24500007-Up) — Italy-built mini excavator, standard configuration | This model uses a plain numeric serial number beginning with the model number (245) followed by a sequential production run starting at 0007-up. It does not carry a 3-letter alpha PIN-prefix code like the Japan-built PC-series. Parts catalogs list this model consistently under this numeric-only scheme. No public year-by-serial decoder chart exists for this range — confirm exact production span with a dealer. |
Frequently asked questions
What engine powers the Komatsu 245 (S/N 24500007-Up)?
No engine make or model is publicly documented for this exact serial range. The 245 is a bare-numbered small excavator built by FAI (Fabbrica Attrezzature Industriali) in Italy for Komatsu, outside the Japan-built PC-series documentation set, so read the engine tag on the block directly and confirm with your dealer rather than assuming a PC-series engine carries over.
What is the operating weight of the 245 (S/N 24500007-Up)?
Operating weight is not published for this serial range. It falls in Komatsu's small/mini excavator size class by chassis and bucket sizing, but no verified weight figure exists in factory or dealer documentation for this exact machine. Confirm with a dealer, or weigh the machine directly, if weight matters for transport or lifting limits.
What replaced the Komatsu 245 (S/N 24500007-Up)?
Komatsu's PC-series mini and compact excavators, built under the alpha-prefix PIN system, superseded this bare-numbered FAI-built lineup after Komatsu took full ownership of the Italian plant in 1995 and rebranded it Komatsu Italia Manufacturing by 1997. No single direct one-for-one successor model is documented for the 245 specifically; the PC-series family covers the size class going forward.
What 245(S/N 24500007-Up) owners discuss
What engine is actually in the 245 (S/N 24500007-Up), and why is it hard to pin down?
No engine make or model is publicly documented for this exact serial range. This is a bare-numbered small excavator that traces to the FAI (Fabbrica Attrezzature Industriali) lineup built in Este/Noventa Vicentina, Italy, for Komatsu starting in the late 1980s, with Komatsu taking full ownership by the mid-1990s and rebranding the line under Komatsu Italia Manufacturing. It sits outside the Japan-built PC-series naming and documentation scheme entirely, so PC-series engine data does not carry over and general Komatsu parts catalogs do not fill the gap. Read the engine tag directly on the block rather than trusting a cross-reference guess, and confirm with your dealer.
How does the hydraulic system typically behave as one of these small excavators ages?
For small mechanical-era hydraulic excavators of this size and class generally, the recurring complaint pattern is sluggish boom, arm, or bucket response once the machine warms up, usually tracing to a worn pump or low/degraded fluid. A whining pump points to air ingestion or low reservoir level; knocking or grinding points to contaminated oil chewing up internal pump parts; spongy or delayed cylinder response usually means worn rod seals letting a cylinder bypass under load. None of this is confirmed against this specific serial range's own service history, but it matches the general complaint pattern reported for machines this size and era. Have a shop pressure-test the system and inspect cylinder seals before relying on it for structural lifting work — have your dealer verify.
What undercarriage wear should an owner expect on this size and class of machine?
Small tracked excavators of this era commonly show track sag from loose tension settings, which accelerates pin and bushing wear, along with worn sprocket teeth and roller or idler seals weeping grease or oil. None of this is documented specifically for the 245 (S/N 24500007-Up), but it is the standard wear pattern reported for mechanical-era mini and midi excavators of similar size. Measure track tension and pad thickness rather than judging by eye, and check idler and roller seals for leakage before buying or after long storage.
Are there known electrical, gauge, or sensor quirks for machines of this generation?
This is a mechanical-era machine with no engine control module, so reported issues for equipment of this age and class center on basic electrical wear items: starter motor drag or failure to engage, glow plug relay or preheat circuit faults in cold starting, charging system output, and simple analog gauge or sender failures. There is no documented electronic diagnostic system for this serial range, and no fault-code list applies. Trace any starting or charging complaint with a multimeter at the battery, starter, and alternator rather than assuming a sensor fault.
Is parts support a common complaint for this model today?
Because this line was built by FAI/Komatsu Italia rather than through Komatsu's mainline PC-series parts network, owners should expect parts sourcing to be more dealer-dependent and slower than for a mainstream PC-series machine. Some wear items such as the starter motor, water pump, or drive sprocket show up cross-referenced against related small Komatsu excavator models in parts catalogs, but a shared listing only proves a shared small-excavator parts platform — it does not guarantee an exact fit or confirm shared engine or fluid specs. Confirm dimensions and mounting against the physical part before ordering.
Do older Komatsu-branded small excavators like this have a reputation for holding up well?
General sentiment toward older Komatsu-branded equipment in this size class is positive when maintenance is kept current: machines running two decades or more past their build date with no major loss of capability are a recurring theme, provided oil changes and routine servicing were not skipped. That reputation applies to the broader era and class of machine rather than being a confirmed track record for this specific serial range, since no dedicated ownership history for the 245 (S/N 24500007-Up) is publicly available.
What should a buyer check before purchasing a used 245 (S/N 24500007-Up)?
Read the plain numeric serial stamped on the machine frame (no three-letter alpha prefix on this line) and get the full string confirmed by a dealer, since no published serial-decoder chart exists for this range. Cycle every hydraulic function under load and watch for pump whine, knocking, or delayed cylinder response. Check track tension, pad wear, and pin/bushing play on the undercarriage. Inspect boom, stick, and bucket pivot pins for looseness and the structure for cracks or repair welds. Confirm cold-start behavior — glow plug/preheat circuit, starter engagement, charging output — since this is a mechanical-era machine with no diagnostic codes to fall back on. Because engine identity, fluid capacities, and factory specs are not documented for this exact serial range, treat any listing that states them as an estimate and have your dealer verify machine identity and condition before you buy.
