Komatsu FD25, FG20, FG25, FG30, FD30 Parts Catalog – 155 Pages OEM

Description

You’ve been burned by aftermarket catalogs before – wrong part numbers, missing revisions, illustrations that don’t match your truck. I’ve seen guys order three brake assemblies before they get the right one because some third-party list mixed up left and right. This Komatsu FD25, FG20, FG25, FG30, FD30 Parts Catalog ends that. It’s the actual OEM print – 155 pages of factory part numbers, exact illustrations, and serial number ranges that tell you exactly which parts fit your machine.

Every forklift in the FG20/25/30-11 and FD25/30-11 series is covered, including the S, G, and SG variants. The serial number table on page 2 shows the cutoff: FG20/25/30 from 450050A up, FG20S/25S/30S from 400001A up, FD25/30 from 430175A up, and FD25S from 480001A up. If your truck falls inside those ranges, the part numbers in this catalog are correct. No guesswork.

155 Pages of Factory Part Numbers

This is not a service manual. This is a parts book. That means every page is built around exploded diagrams and corresponding parts lists. You get the exact Komatsu part number for every nut, bolt, seal, brake shoe, steering component, and hydraulic line. The illustration figures (like FIG.3701A for the brake system) are indexed directly to the part list. Each list includes the index number, part number, description, quantity per assembly, and which truck models it applies to. Page 3 states clearly that this catalog covers only chassis parts – for engine internals, you need the separate Engine Parts Book.

What Serial Numbers Are Covered?

Page 2 of the catalog lists the serial number ranges for each model. The FD25 and FD30 diesel trucks start at 430175A. The FG20, FG25, FG30 gasoline machines start at 450050A. The S variants (indoor/diesel) have their own ranges. Always verify your truck’s serial number before ordering – the parts catalog is model-specific, and if your serial is before the cutoff, you may need an earlier revision. The application table on page 3 also lists machine codes: FD25T-11, FD25ST-11, FG20T-11, etc., with transmission types (C for clutch, T for Torqflow). Knowing your code is as important as the model number.

Komatsu FD25, FG20, FG25, FG30, FD30 Parts Catalog: Illustrated Breakdown

The catalog uses a two-part system. First, a full-page illustration showing the assembly with index numbers. Second, a parts list table below or on the facing page. The brake system figure (3701A) shows the backing plate assembly, brake shoes, wheel cylinders, and hardware. Each part has a star (*) next to it if it’s not available individually – those are assembly-only items. A dot before the part name means it belongs to the assembly above. Two dots mean sub-assembly. This hierarchy is explained on page 5. If you’re replacing a wheel cylinder on an FG25, you find the figure, note the index number, cross-check the part number, and order. No flipping through endless pages of generic diagrams.

Brake System and Other Assemblies

The catalog breaks down every major system: steering, axle, transmission, mast, hydraulics, electrical. For the brake system, the illustration on page 4 (FIG.3701A) shows the left and right brake assemblies separately – part numbers 3EB-30-23103 and 3EB-30-23203. The backing plate assembly is listed with its own part number. If you need the individual shoes, those are listed under the backing plate with a dot, indicating they’re part of the assembly. This level of detail is what you pay for with OEM documentation. Aftermarket catalogs often combine left and right into one ambiguous number – then you get the wrong side and lose an hour of labor.

Gasoline vs Diesel: Which Engine Manuals You Need

The Komatsu FD25 and FD30 models use the 4D95S.W Komatsu diesel engine. The FG20, FG25, and FG30 use either the H20 Nissan gasoline engine (FG20/25/30) or the G1600 Hercules engine (FG30G/FG30SG). This parts catalog does not include engine parts – it refers you to the separate Engine Parts Book for pistons, rings, gaskets, and cylinder heads. If you’re working on the diesel engine, pair this chassis catalog with KOMATSU Forklift Shop Manual – Diesel Engine for service procedures. For engine overhaul parts, the Komatsu BX50 FG20 FG25 FG28 FG30 2006 Parts Catalog – 932 Pages covers a wider range. For older models, check Komatsu FG20, FG30, FG20H, FG20N, FG30N Parts Catalog – OEM Specs as a supplement. Understanding the difference between gasoline and diesel fuel systems helps – this Wikipedia article on diesel engines gives background. For deeper reading, this Wikipedia article on diesel engines explains the combustion cycle.

Order Parts Correctly: Using the Parts List and Index Numbers

When you open the catalog, each figure has a number like 3701A. The parts list uses index numbers in parentheses – (1), (2), etc. – that correspond to the illustration. The part number column gives the genuine Komatsu number. The description column includes abbreviations in brackets, like (H20) for gasoline engine application. Quantity is per assembly. The application column shows which models and serial ranges each part fits. For example, brake assembly (L.H) part 3EB-30-23103 applies to FG20 T-C from 450050A up, FG25 T-C, and FG30 T-C. If you order from this catalog, you get the exact part that came on the truck from the factory. No returns, no re-explaining to the parts counter guy.

Frequently Asked Questions

Does this parts catalog include torque specifications?

No. This is a parts catalog, not a service manual. Torque values are in the shop manual.

Can I use this manual for the FD25S model?

Yes. The FD25S is listed with serial number range 480001A and up, found on page 2 of the catalog. It covers both the FD25 and FD25S variants, as well as the FD30S. The serial number table on page 2 confirms the FD25S-11 is included. If your truck falls within that range, the part numbers are correct. Also note that the FD25S has a specific machine code FD25ST-11 listed on page 3 under application machines for USA. This catalog is for 2.5-ton diesel trucks with Torqflow transmission. So yes, you’re covered.

What is the difference between this and the engine parts book?

This catalog covers chassis parts – everything except the engine. For engine parts like pistons, rings, and gaskets, you need the separate Engine Parts Book. The introduction on page 3 states that clearly.

How do I read the parts list?

Each figure has index numbers. The parts list shows the index, part number, description, quantity, and application. A dot before a part name means it’s part of an assembly. See the legend on page 5.
