The Komatsu 222 (S/N 22201043-Up) is a small-class, rubber-tracked hydraulic excavator, sized within Komatsu's own compact bracket up through the PC90 range rather than a mid-size machine. It runs a Perkins diesel with a mechanical injection pump and governor - no ECM, no electronic monitor panel, no stored fault codes. Operating weight and dig-depth figures are not published for this exact serial range; treat it as a mini/compact-class machine and confirm exact figures against the parts book or a dealer using the full serial number. The machine started out built by Fabbrica Attrezzature Industriali (FAI) of Italy from 1988 to a Komatsu-influenced design. Komatsu took a minority stake in FAI in 1989 and full ownership in 1995, after which the excavator continued to be sold under the Komatsu name. Factory configuration on this serial range includes a rear backfill blade, pin-on buckets from roughly 250 mm to 550 mm (10-22 in) wide, and a single auxiliary hydraulic circuit pre-plumbed for one attachment such as a hydraulic hammer, on rubber or steel track shoe options.

The FAI-to-Komatsu transition is the defining change in this line: the badge moved from FAI to Komatsu/FKI as ownership consolidated through the 1990s, but the chassis, hydraulics, and Perkins powerplant carried through rather than a clean-sheet redesign. The serial plate reflects that origin - it reads as a model code plus a straight sequential unit count, not the letter-prefix format used on Japan-built Komatsu ranges, so parts lookups have to match this exact model-and-serial heading rather than assume a cross-reference to a same-numbered Japan-built machine. This model never built the owner-forum or spec-aggregator footprint that Komatsu's mainline excavators have, since it sold in limited numbers under a joint-venture badge in a specific European market window. In the used and parts market today that obscurity cuts both ways: values are set locally and opportunistically rather than off a published guide, but undercarriage, track, and pin-and-bushing wear parts remain available through aftermarket suppliers, because small rubber-tracked excavators of this size class stayed in demand for rental and resale fleets long after the FAI badge disappeared.

Komatsu 222(S/N 22201043-Up) maintenance schedule

Service interval	Tasks
Every 50 h	Check engine oil level before daily start-up and top up if low. Check coolant level in the radiator or reservoir daily. Check hydraulic oil level with the boom and arm retracted. Grease boom, arm, and bucket linkage pins daily. Check track tension weekly and adjust if sagging beyond the cold-measurement guideline. Drain water and sediment from the fuel water-separator bowl weekly.
Every 250 h	Change engine oil and replace the oil filter. Check alternator and fan belt tension and condition. Grease the swing bearing and blade pivot points. Check battery terminals and charging-circuit connections for corrosion. Inspect rubber track pads for cracking, chunking, or exposed steel cord.
Every 500 h	Replace the fuel filter element and bleed the fuel system. Check injection-pump timing and governor linkage against the factory setting. Check final-drive and swing-drive gear-oil level. Clean radiator and oil-cooler fins of packed debris. Inspect hydraulic hoses and cylinder rods for leakage or scoring.
Every 1,000 h	Replace the hydraulic return-filter element. Check and adjust engine valve clearance. Change final-drive and swing-drive gear oil. Check the auxiliary hydraulic circuit relief valve if a hammer or tool is fitted. Inspect the wiring harness at the boom-base and cab-floor pass-throughs for chafing. Check sprocket, idler, and roller wear against track pitch.
Every 2,000 h	Replace hydraulic tank oil and clean the suction strainer. Replace engine coolant and flush the cooling system. Check injector pop-off pressure and spray pattern. Check swing-circle mounting bolts for torque and bearing play. Inspect structural welds on the revolving frame, boom, and ROPS or canopy for cracking.
Every 4,000 h	Rebuild or reseal the hydraulic pump and cylinders once leakage or drift develops. Rebuild final-drive and swing-drive units if gear oil shows metal contamination. Replace worn rubber track, sprockets, and rollers as a matched set. Compression-test the engine and pop-test injectors if starting or power complaints persist. Inspect and repair the ROPS or canopy structure if cracks or old field welds are found.

Servicing the 222(S/N 22201043-Up) beyond the schedule

Predictive Maintenance & Fluid Analysis

This machine's Perkins diesel is mechanically governed with no ECM and no telematics, so fluid sampling is the predictive tool, not a dash warning light. Send engine oil out at every change interval and watch for coolant intrusion, a sign of head-gasket or liner-seal trouble. Sample final-drive and swing-drive gear oil for metal fines before wear shows up as noise or slop. Watch hydraulic oil condition too, since a mechanical valve bank can't flag drift on its own, so boom or bucket creep under load is the first warning sign.

Corrective & Common Repairs

Expect injection-pump timing to drift gradually rather than fail outright on this mechanically governed Perkins engine, so chase rough idle or power loss with a compression check and injector pop-test before touching timing. Rear-main-seal and timing-cover oil seepage are common as hours climb. Hydraulic cylinder seal wear shows up as boom or bucket drift under load. Charging faults are usually corroded battery or starter connections, or a tired alternator or rectifier. Wiring harness chafe at the boom base and cab-floor pass-throughs is a recurring fault after decades of flex.

Overhaul & Rebuild Points

Rubber tracks on this crawler wear fastest when run too tight or too loose; abrasive ground chews through the rubber compound and steel cores faster than dirt or turf. Inspect sprockets and rollers whenever track is replaced, since new track over worn sprockets burns out fast. Bucket-linkage pins and bushings are the highest-wear zone on the machine and the first place to check for slop. Given its age, inspect the revolving frame, boom, and ROPS or canopy for cracking or old field-weld repairs before returning it to work.

Seasonal & Environment Servicing

Choose rubber track for finished-surface or paved work and steel shoe for abrasive demolition or quarry ground, since track compound wear accelerates fast on the wrong surface. Check track sag cold at the mid-roller before a cold-weather shift, since sag readings taken warm run loose once the machine cools. This mechanical Perkins engine has no glow-plug or block-heater electronics to lean on in cold climates, so battery condition and fuel-gelling protection matter more than usual. Protect aging wiring and connectors from road salt and moisture.

222(S/N 22201043-Up) attachments & work tools

Buckets

The factory parts breakdown for this serial range lists digging buckets in 250 mm (~10 in), 350 mm (~14 in) and 550 mm (~22 in) widths, plus a 450 mm (~18 in) unit called out as the standard bucket. Each width is also offered as a bucket-with-hook variant for light lifting duty. All buckets are pin-on, direct-mount units - no coupler-style mount is shown in the catalog. GD/HD/rock capacity ratings are not published for this exact serial range; width is the only OEM-documented dimension, consistent with a small-class mini excavator.

Hydraulic hammers

No breaker fitment chart is published for this exact serial range. The machine's own catalog does show a dedicated control valve and hydraulic piping set built specifically for an attachment circuit, confirming factory provision for a single auxiliary tool. Given this unit is grouped in the small size class (its own series classification runs up through the PC90 size range) and its bucket range tops out at 550 mm, any hammer fitted would sit in the light/compact breaker weight class - exact class varies by configuration and should be matched to actual pump flow and relief pressure, not assumed.

Quick couplers

The OEM catalog for this serial range shows only pin-on bucket mounting - no quick-coupler assembly appears in the factory parts breakdown. A coupler was not standard or catalog-listed equipment on this machine. Pin-grabber or wedge-type couplers sized for a small-class mini excavator could be retrofitted, but no fitment is documented for this exact serial range - verify boom/arm pin spacing with your dealer before ordering one.

Thumbs/grapples

Not documented for this exact serial range in the OEM catalog or dealer literature. Hydraulic thumb kits and grapples are aftermarket, size-matched accessories on excavators of this class; none are listed as a factory option in this machine's parts breakdown.

Rippers

Not documented for this exact serial range. The factory catalog lists a dozer-style blade with its own blade cylinder for backfilling and site cleanup, but no boom-mounted ripper tooth or ripper assembly appears anywhere in the OEM parts breakdown for this machine.

Hydraulic-kit notes

The catalog confirms a separate control valve and hydraulic piping set for attachment use, distinct from the main travel/blade and boom/arm/bucket circuits, meaning this machine left the factory pre-plumbed for one auxiliary tool line (suited to a hammer or similar single-acting tool). No flow or pressure rating for this circuit is published for this exact serial range - confirm the actual specification against the shop manual or with your dealer before fitting a high-demand tool.

222(S/N 22201043-Up) serial number reference

The ID plate is normally riveted to the machine frame near the operator's station or on the front chassis rail. Because this is an Italy-built mini excavator rather than a Japan-built Komatsu range, plate placement and the numbering scheme can differ from later Japan-built PC-series machines - check the frame and cab post directly. Read the stamped number as model code plus sequential unit count: a plate stamped 22201043 breaks down as model 222, production unit 01043, rather than a three-letter alpha prefix followed by digits. If the stamped number does not follow that pattern, the machine falls outside this parts listing - check the plate against a dealer reference before ordering parts.

Prefix	Identifies	Notes
222	Standard/base configuration - Perkins-powered, rubber-tracked mini excavator built under the FAI/Komatsu partnership in Italy	The leading digits of this PIN are the machine's own factory model code, not a separate alphabetic plant/series prefix like the letter codes used on Japan-built Komatsu ranges. This range covers a mini excavator built at the Italian plant during the years Komatsu partnered with, then owned, the local manufacturer: Komatsu took a minority shareholding in 1989 and full control in 1995, after which the machine continued to be sold under the Komatsu name (the original Italian brand name was dropped by 1997). Runs a Perkins diesel on rubber tracks, not a wheeled undercarriage. The Italian builder's mini excavator lineup covered several separate model sizes; 222 is its own distinct model, not a sub-variant of a smaller or larger sibling in that lineup. No separate lettered sub-variant prefix (long-undercarriage, wheeled, alternate engine) is documented for this serial block in available sources - confirm any option-specific break point with a dealer before ordering parts.

Frequently asked questions

What engine does the Komatsu 222 (S/N 22201043-Up) use?

It runs a Perkins diesel with a mechanical fuel-injection pump and governor - no ECM and no electronic monitor. The exact Perkins displacement and cylinder count are not published for this exact serial range, which reflects the machine's origin as a small excavator built by an Italian manufacturer under a Komatsu-influenced design before Komatsu took full ownership. Confirm the exact engine variant against the machine's own nameplate or parts book.

What is the operating weight of the Komatsu 222 (S/N 22201043-Up)?

Operating weight is not documented in publicly available sources for this exact serial range. Based on its own size classification, grouped with Komatsu's small excavators up through the PC90 bracket, and its bucket range of roughly 250-550 mm, it sits in the mini/compact excavator class rather than a mid-size machine. Verify the exact figure against the machine's nameplate or parts book for this serial range.

What replaced the Komatsu 222?

No source ties a specific successor model directly to this serial range. Komatsu took full ownership of the Italian builder in 1995, renaming it and folding production into Komatsu's own compact-excavator business, so this line was effectively absorbed rather than replaced by one named model. Later small excavators sold under the Komatsu badge from that plant carry the lineage forward.

What 222(S/N 22201043-Up) owners discuss

What engine is actually in the Komatsu 222 (S/N 22201043-Up), and what quirks come with it?

This machine runs a Perkins diesel, not a Komatsu-branded block, a holdover from its start as a small excavator built by an Italian manufacturer before Komatsu took full ownership. The exact Perkins displacement isn't pinned down in public literature for this serial range, but the fuel system is mechanically governed and pre-electronic: no ECM, no fault codes, just an injection pump and a mechanical governor. Mechanical diesels of this vintage in small excavators are known for slow rear-main-seal and timing-cover oil seepage as hours climb, and for injection-pump timing drifting gradually rather than failing outright. With no self-diagnostics, a rough idle or power loss gets chased the old way: compression check, injector pop-test, then fuel filtration. Have your dealer verify injection timing before any adjustment.

How does the hydraulic system behave as this machine ages?

Small excavators of this era and size show a common pattern: functions stay crisp on warm, clean oil, then get sluggish or start to drift (boom or bucket creeping down under load) once seals age or the oil picks up contamination. The valve bank on a machine this old is mechanically controlled, so there's no smart diagnostics to point at a cause, meaning oil condition and filtration get checked first, then cylinder seal leakage, then relief-valve settings. No relief-pressure figures are published for this exact serial range, so any pressure check needs to reference the machine's own service literature rather than a generic number. Have your dealer verify relief-valve settings before adjusting them.

What undercarriage and track wear patterns should owners expect?

This is a rubber-tracked crawler, and the wear pattern matches small rubber-tracked machines generally: tracks run too tight wear fast, tracks run too loose slip or de-track, and abrasive ground (sand, gravel, demolition debris) chews through the rubber compound and steel cores faster than dirt or turf. A rough working target for track sag on machines this size runs around 20-30 mm (0.8-1.2 in) measured cold at the mid-roller, but that figure varies by undercarriage configuration and no factory number is published for this exact serial range, so treat it as a general guideline, not a spec. Sprockets and rollers should be inspected any time track is replaced; fitting new track over worn sprockets burns through the new track quickly.

What electrical or sensor problems come up on this model?

This machine predates sensor-heavy, electronically managed excavators, so there is no fault-code system to lean on. The complaints that surface for equipment this old are electrical-mechanical rather than sensor-driven: corroded battery and starter connections, an alternator or rectifier that no longer holds charge, and wiring harness chafe at pivot points such as the boom base and cab floor pass-throughs after decades of flex. Diagnosis is multimeter-and-wiring-diagram work, not a code reader. A charging system that won't hold the battery overnight is the most common starting point for a complaint.

Does the machine's Italian joint-venture origin cause parts or identification headaches?

Yes. The model number and serial plate on this lineage do not follow the letter-prefix convention used on Japan-built Komatsu ranges. The '222' functions as the model's own numeric code ahead of a plain sequential serial, which trips up anyone used to reading Japan-built Komatsu PINs at a parts counter. Sourcing parts for this exact serial range goes best by matching the parts-book heading and full serial number exactly rather than assuming it cross-references a same-numbered Japan-built Komatsu machine, because there isn't one.

Is there much owner or mechanic discussion of this specific machine online?

Not much. This model sold in limited numbers under a joint-venture badge before Komatsu absorbed the manufacturer outright, so it never built the kind of owner-forum footprint that Komatsu's mainline Japan-built excavators have. What surfaces tends to be parts listings and regional used-equipment ads rather than troubleshooting threads. General small-excavator and Perkins-diesel discussion is reasonable as directional guidance for this machine, but anything serial-specific should be checked against the physical parts book and operation manual for this range.

What should a buyer check before purchasing a used Komatsu 222 (S/N 22201043-Up)?

Start at the serial plate and confirm it reads in the model-plus-sequential-unit format for this range; a re-stamped or mismatched plate on a machine this old is a known headache once you try to order parts. Pull the engine oil dipstick and check for a milky or foamy sample pointing to a head gasket or cooling cross-contamination issue, watch for smoke on cold start, and run a compression check if the engine feels weak, since there is no ECM to pull codes from. Cycle every hydraulic function through full travel to check for cylinder drift and listen for pump cavitation. Walk the undercarriage for track tension, sprocket and roller wear, and any cracking or bulging in the rubber. Given the machine's age, inspect the revolving frame, boom, and ROPS or canopy structure for cracks or old repair welds, and confirm lighting, wiper, and heater circuits work, since wiring this old is a common failure point. Have your dealer verify the structural condition of the ROPS/canopy and any welded repairs before the machine goes back to work.
