Every week we get the same message: "I have a Komatsu PC200-8, which filter do I buy?" The answer is always a part number — and the number has to come from a reliable source, not from a listing where someone typed it from memory. This guide shows where the official Komatsu parts catalog lives, how the numbering system works, and which numbers we can confirm for the PC200-8, the highest-volume excavator in its class on the used market.
1. Where to Find the Official Komatsu Parts Catalog
Komatsu's official parts lookup is the PartSearch portal (partsearch.komatsu.com) run by Komatsu's regional organizations — in North America that is Komatsu America Corp. You search by machine model or part number, and it returns the factory part with its current number. Outside North America, the local Komatsu distributor operates the same kind of portal, and every dealer can issue the parts catalog for your model — the familiar PDF sections (engine, hydraulic, undercarriage, cab) with part numbers, descriptions and quantities per machine.
Three practical notes from the way we use catalogs daily:
- Catalogs are model- and series-specific. A PC200-8 catalog and a PC200-8M0 catalog are different documents. Order the one that matches the exact model and production year on your machine's serial plate.
- PDFs from unofficial sites are risky. Free "full Komatsu catalog" downloads floating around forums are often outdated or incomplete — a superseded number in an old PDF sends you to a part that no longer exists.
- The portal is the authority. When an old number and the portal disagree, the portal wins — that is exactly how supersessions get discovered (see the radiator change in Section 3).
2. How Komatsu Part Numbers Are Structured
Komatsu part numbers are built from three hyphen-separated segments:
- Model-family code — identifies the machine family the part was designed for. The 20Y prefix, for example, belongs to the PC200-8 family: 20Y-03-41651 (radiator) and 20Y-60-41130 (return filter) are both PC200-8 parts.
- Group code — the assembly group within the machine (filters and hydraulics, engine, cooling, and so on).
- Sequence number — the individual part within that group.
Two cautions. First, prefixes are not always exclusive — 207-60-71181 carries the 207 code and is listed across the PC200-7/8, PC220-7/8, PC240-8 and PC300-7 families, so the number itself, not the prefix alone, is what you verify. Second, a changed digit in the middle of a number is a different part, not a typo; this is the most common trick in fake listings, and our fake filter guide covers the other red flags.
3. Verified Part Numbers: the PC200-8 Family
The table below lists PC200-8 numbers we have cross-checked against live aftermarket listings and our own order history (checked August 2026). Treat it as your starting point — the final confirmation for any order is the machine serial number.
| Part | Komatsu no. | Fitment / notes | On our site |
|---|---|---|---|
| Hydraulic oil filter | 207-60-71181 | PC200-7/8, PC200LC-8, PC220-7/8, PC240-8, PC300-7 | Product page → |
| Hydraulic return filter | 20Y-60-41130 | PC200-8 (also 20Y-60-31140 suction strainer) | Product page → |
| Return oil filter | 21W-60-41150 | PC200-8 | — |
| Air filter | 600-185-4100 | PC200-8 standard air filter; pre-cleaner 21N-01-31330 for PC200-8M0/PC220-8 | Product page → |
| Cabin / AC filters | 17M-911-3530 / 208-979-7620 | Cab air filter and air-conditioning filter | — |
| Intercooler | 20Y-03-41131 | Aluminum core, PC200-8 family; ~$715 listed Aug 2026 | Guide → |
| Radiator | 20Y-03-41651 | PC200-8, PC210-8, PC230NHD-8K; supersedes 20Y-03-42451 | Product page → |
The full filter set — with replacement intervals and the part numbers for every service point — is in our Komatsu PC200-8 filter guide. Note what is deliberately not in the table: the diesel fuel filter. Its number changes with the SAA6D107E-1 engine specification, which varies by market, so it is confirmed by serial — we never quote one universal number for it.
4. Ordering Aftermarket Parts with an OEM Number
An OEM Komatsu number is all a good aftermarket supplier needs to find the right part — most replacement filters, radiators and cooling parts are cross-referenced against the factory numbers. What separates a clean order from a return is what you send alongside the number:
- Machine serial number (PIN) — this catches build-to-build changes that the number alone misses.
- Photos of the old part — for anything with mounting points (radiator, cooler), we compare core size, tank shape and bracket positions.
- Any number stamped on the old part — a readable old number is cross-referenced directly.
On price: quality aftermarket parts for this class typically run 30–60% below OEM list — a 20-ton class excavator radiator (PC200-8 size) is roughly $250–600 aftermarket against $900–1,800 OEM, as on the PC200-8 radiator 20Y-03-41651 page. Two numbers worth quoting together are the radiator and the intercooler, since both sit in the same cooling package and the freight math favors one crate.
One more habit that saves money: check whether your number has been superseded before ordering. The PC200-8 radiator is a live example — the earlier core 20Y-03-42451 was replaced by 20Y-03-41651, and old PDFs still show the old number. Our Komatsu PC200 hydraulic pump guide and the hydraulic filter guide follow the same logic for their parts.
FAQ
Q: Where can I download a Komatsu spare parts catalog PDF?
A: Start with Komatsu's official parts lookup, the PartSearch portal (partsearch.komatsu.com) for North America; other regions use the local distributor's portal. If the portal is region-locked, ask your dealer for the parts catalog PDF for your machine model — dealers issue model-specific catalogs on request. There is no single all-models PDF; catalogs are organized by model and production series.
Q: How is a Komatsu part number structured?
A: Three hyphen-separated segments: model-family code, group code and sequence number. As a rule of thumb the first segment identifies the model family — the 20Y prefix appears across PC200-8 parts such as 20Y-03-41651 (radiator) and 20Y-60-41130 (return filter). Prefixes are not always exclusive to one model, so confirm against the catalog page for your machine.
Q: What is the hydraulic oil filter part number for a Komatsu PC200-8?
A: 207-60-71181 is the commonly listed hydraulic oil filter, cross-referenced for PC200-7/8, PC200LC-8, PC220-7/8, PC240-8 and PC300-7. The air filter is 600-185-4100 and the return filter is 20Y-60-41130. The diesel fuel filter number varies with engine spec — confirm by machine serial.
Q: Can I order aftermarket parts using an OEM Komatsu number?
A: Yes. Send the OEM number plus your machine serial; a reliable supplier cross-references the part and confirms fitment before dispatch, typically at 30–60% below OEM list. Beware of listings where a single digit in the number has been changed — cross-check before paying.
Need a Komatsu Part Number Confirmed?
