The PC-series machines in the documented extract — PC200-8, PC300-8, PC120-6, PC400-6, PC138US-10 — share a pattern: the orders are fuel-system and electrical. That matches how these machines age: injectors and solenoids wear on hours, harnesses chafe, and turbos follow the engine's oil history. The table below is the documented extract; hydraulic repair kits for Komatsu pumps are also documented store listings, and Komatsu engines are one of the Inline 6 diagnostic platforms in the engine repair solution.

Identifying Komatsu Parts
- Use the full injector number set. The PC200-8 listing carries three numbers; supersessions are normal, and quoting all of them prevents a near-match.
- Engine before machine for engine parts. The SAA6D125 and 6D114 listings are engine-led — the engine plate settles them.
- Photograph harness connectors. The PC400-6 harness match depends on connector layout as much as on the number.
Delivery and preparation times are confirmed for your order in the enquiry reply, in writing and before payment: the reply states the times, the packing and the shipping method that apply to your exact part number. Times are confirmed per order rather than published as a general figure, because they follow the listing, the quantity and the destination.
Frequently Asked Questions
Are these parts made by Komatsu?
No — and this page does not pretend otherwise. Kyotechs is an independent aftermarket supplier; the parts listed are compatible with Komatsu machines. Each listing states its own specification and condition, and the enquiry reply confirms exactly what will ship.
Do the parts carry a warranty?
Warranty terms are confirmed in writing for each order before payment. Kyotechs' own FAQ states that most parts are backed by a warranty against manufacturing defects; ask for the term that applies to your listing when you enquire.
Komatsu Range Notes
Two features of the documented Komatsu range deserve emphasis. First, its centre of gravity is the fuel system: two injector listings covering the PC200-8/PC300-8 application and the SAA6D125 engine account for the most common Komatsu enquiries, because common-rail injectors wear on hours and fuel quality alike. Second, the electrical listings — the rotating solenoid valve for the PC60/PC120 generation and the PC400-6 harness — serve machines old enough that harness condition and connector integrity decide as many faults as the components do. Buyers of either should read the linked family pages: the injector page's pre-replacement checks and the harness page's diagnosis method apply to Komatsu machines exactly as written.
Komatsu's Dash numbering (PC200-7 versus PC200-8, PC300-7 versus PC300-8) separates machine generations with different fuel and electrical systems, and the documented listings respect it exactly — the injector listings on record name the -8 models (PC200-8 and PC300-8) only, so they are quoted against those machines. Where a listing names only one generation, do not extrapolate it to the other in your order; ask, and the reply confirms or refuses against the record.
