Komatsu BX50, FG20-16, FG25-16, FD20-16, FD25-16 2006 Parts Catalog

I’ve been turning wrenches in San Antonio for 28 years, and I’ve lost count of how many parts orders got held up because a tech grabbed a reprint catalog with fuzzy illustrations and wrong part numbers. The Komatsu BX50, FG20-16, FG25-16, FD20-16, FD25-16 2006 Parts Catalog is the factory document – not some aftermarket scan job. It’s 932 pages of OEM exploded views, Fast Moving Stock Lists, and the part numbers that actually match the truck on your lift.

This thing came off the press at Komatsu Forklift USA in Covington, Georgia, October 2006. It covers BX50 Series with gasoline, LP, and diesel models – all starting at serial number 200001A~. If you’re ordering a piston or a gasket for an FD25-16, you need the number from page 00-01 of the FRSL, not some third-party site that guesses. I’ve seen too many guys bolt on a wrong bearing and then wonder why it burns oil.

Parts Breakdown: Engine Assembly (FG20-16, FD25-16)

Flip to any engine section and you’ll see clean, factory-inked exploded views with each part numbered directly. The manual organizers it by figure numbers and page numbers – you don’t hunt through 200 pages of generic engine stuff. For the FG20-16 gas engine, the intake manifold gasket part is listed with Komatsu’s own code, not repackaged. For the FD25-16 diesel, the injection pump components get their own figure. You can cross-reference the serial number range printed right in the book – serial 200001A~ and up – so you know the revision level.

What the Fast Moving Stock List Tells You

Every shop that services these trucks should know the FMSL – the Fast Moving Stock List. That’s the stuff that breaks most often: filters, belts, seals, hoses, gaskets. The catalog dedicates its entire Chapter 00 to these lists. There’s a Full Recommended Stock List (FRSL) too, for the parts you don’t want to scramble for on a Friday afternoon. If you stock a shop that touches BX50 trucks, this section alone pays for the catalog the first time you avoid a $50 rush freight charge.

3 Reasons to Use OEM Parts Catalog Over Aftermarket Reprints

First, the aftermarket reprints I’ve seen copy the images so poorly that bolt holes disappear and callouts don’t align. You order the wrong seal because the drawing looks like a blurry photocopy. Second, aftermarket catalogs often drop pages – especially the introduction and copyright page that list the valid serial number ranges. Without that, you might order parts for a pre-2006 update and they won’t fit. Third, this OEM catalog includes the proposal for manual revisions form – page 3 – so you can report errors directly to Komatsu. Good luck doing that with a pirate PDF.

Track Down the Right Part Number – Fast

When a truck comes in with a blown head gasket on the FD20-16, you don’t want to waste an hour cross-referencing online. This catalog puts the figure right there, lists the item number, the Komatsu part number, the quantity needed, and sometimes even notes like “includes washer.” Page numbers are all printed at the bottom – you can mark your commonly used sections with sticky tabs. I keep a set of these manuals in the tool room for every line of trucks we service. It stops the argument between the tech and the parts guy cold.

Fast Moving Stock List (FMSL) and Full Recommended Stock List (FRSL): Chapter 00

Go to the table of contents – page 5 shows the structure. Chapter 00 is specifically the Recommended Stock List. The FMSL starts at figure 00-0001 and goes on. The FRSL follows. These lists are based on real failure data from Komatsu’s field service network, not some marketing writer’s guess. If you’re setting up a maintenance inventory for a fleet of BX50 forklifts, you can trust this list.

I’ve talked to shop owners who spent $2,000 on parts they never touch, because they bought a generic “forklift parts book” from a chain. That money could’ve gone into a good set of wrenches. This catalog costs a fraction of that and saves you the headache of wrong parts. Komatsu BX50 FG20 FG25 FG28 FG30 2006 Parts Catalog – 932 Pages is the same publication – but make sure you get the version for your exact serial range.

FAI Komatsu 67-80DT Parts Catalog – OEM Hydraulic Steering Piston List covers a different line, but if you work on older Komatsu forklifts, it’s worth having. Komatsu WH609-1 WH613-1 Parts Catalog | 347 Pages OEM is for the heavy metal – the big pneumatic-tire trucks. For a deeper dive into diesel fundamentals, read this Wikipedia article on diesel engines – it’s solid background, but the part numbers you need are in the catalog.
