Komatsu BX50, FG20, FG25, FG28, FG30 2006 Parts Catalog

If you’ve ever ordered a part for a BX50 and ended up with something that didn’t fit because the aftermarket catalog cross-referenced wrong, you know the drill. That’s downtime. That’s a lift sitting on jack stands while you wait for the right part. This Komatsu BX50, FG20, FG25, FG28, FG30 2006 Parts Catalog is the factory document – 932 pages of OEM part numbers, exploded diagrams, and stock lists. Not a reprint. Not a third-party compilation. Original Komatsu Forklift USA publication PM240 R1, revised October 2006.

Fast Moving Stock List (FMSL) – What to Keep on Hand

Chapter 00 opens with the Fast Moving Stock List. These are the parts you’ll burn through – filters, seals, gaskets, belts. The manual breaks them into three sections: FMSL (Fast Moving Stock List), Full Recommended Stock List (FRSL), and an EPA Related Stock List (EPASL). If you run a shop that sees a lot of BX50-series trucks, you want that FMSL taped to your parts room wall. Page references in the TOC point you straight to the figure numbers so you can order without guessing.

EPA Related Stock List – Why It Matters

BX50 models are EPA emission compliant. That means certain components – carburetors, vapor recovery fittings, specific hoses – aren’t interchangeable with pre-emissions trucks. The EPASL section (00-0002 and following) lists every emission-related part number. Miss one of those and your truck won’t pass a visual inspection, or worse, it’ll run lean and burn a valve. Komatsu covered this specifically because these trucks are built for the U.S. market.

Filters Section – Don’t Guess the Element Number

Filters section is buried in Chapter 00 as well. Oil, fuel, air, hydraulic. Each figure shows the element with its Komatsu part number. I’ve seen aftermarket catalogs swap an FG20 filter onto an FG30 because they think the engine is the same. It’s not. The FG20 uses a different air cleaner housing. This catalog gives you the right number the first time. Compare that to browsing a generic parts website and you’ll see why this PDF is worth having on your tablet.

Forklift Trucks Covered (S/N 200001A~) – Are You In Range?

Page 13 of the catalog lists every truck model covered. BX50 series includes gasoline/LP models FG20, FG25, FG28, FG30, FG32, FG35-16 and diesel models FD20, FD25, FD28, FD30, FD32, FD35-16. Serial number range starts at 200001A. If your truck falls in that range, this is the correct parts book. If you’re working on an earlier model, you need a different publication – check our related manuals below.

Does This Catalog Cover Diesel and LP Models?

Yes. The BX50 series includes both gasoline/LP and diesel variants. The catalog lists parts for both fuel systems separately. For diesel engine specifics, you can reference this Wikipedia article on diesel engines for general background, but for part numbers you need the factory listing. The diesel sections under each figure will note “For FD models” or similar. Do not assume the LP and diesel share the same cylinder head gasket – they don’t. The catalog’s exploded views will show the difference.

Get the Right Part Number the First Time

This is what a parts catalog does: it tells you exactly which bolt, which gasket, which seal goes where. The TOC includes figure numbers for every assembly – powertrain, steering, mast, hydraulics, electrical. You look up the figure, find the item number, and the corresponding part number is right there. No cross-referencing, no calling the dealer. If you need to repair the mast on an FG25, you’ll find the section easily. Related manuals like KOMATSU Forklift Shop Manual – Diesel Engine give you the torque specs for reassembly – pair that with this catalog for the part numbers.

I’ve been turning wrenches for 28 years. Aftermarket parts catalogs are fine for a ballpark, but when you need to confirm a bearing number for a steering axle on a BX50, you want the factory book. This one also includes a proposal-for-corrections form in the front – meaning Komatsu actively asks users to report errors. That’s how you know it’s maintained. Komatsu FG/FD Series Forklift Parts Catalog covers older series, but this 2006 revision adds EPA-specific parts and updates for the BX50 chassis.

For a complete reference set, also grab Komatsu BX50 Series Forklift Trucks Parts Manual PM240 R1. That’s this same document – just confirming the full title. And if you want to understand how a diesel four-cycle works, this Wikipedia article on diesel engines gives general theory, but it won’t tell you the part number for the injection pump seal on a BX50 diesel. Only this catalog will.

Is this the same as a service manual?

No. This is a parts catalog – part numbers, not repair procedures. You need the shop manual for torque specs and disassembly steps.

What serial number range does it cover?

BX50 series with serial number starting at 200001A. That includes FG20, FG25, FG28, FG30, FG32, FG35-16 and the corresponding FD diesel models. If your truck’s S/N is below that, you need an earlier edition – check our store for older Komatsu parts catalogs.

Does it include diagrams for the mast and hydraulics?

Yes. Every major assembly is covered with exploded-view drawings. The TOC lists figure numbers for engine, transmission, drive axle, steering, mast, hydraulic system, and electrical components. Each figure itemizes the parts with Komatsu part numbers.

Can I print this PDF?

Yes, it’s a standard PDF. 932 pages. You can print individual pages or sections as needed. Keep a copy in the shop computer and a binder for the tool box.
