Toyota 4FB20, 4FB25, 4FBJ20, 4FBJ25 Parts Catalog – OEM Factory Specs

If you’ve ever ordered a part for a Toyota 4FB20 forklift and ended up with something that didn’t fit, you know the pain. Time wasted, money burned, and a machine sitting idle. This is the Toyota 4FB20, 4FB25, 4FBJ20, 4FBJ25 Parts Catalog – the OEM reference that tells you exactly what goes where. No aftermarket guessing game. No third-party reprints. Just factory data from Toyota Motor Corporation and Toyoda Automatic Loom Works.

This 136-page document is a parts catalog, not a service manual. It won’t tell you torque specs or overhaul procedures. But if you need to identify a component – whether it’s a hydraulic seal, a mast roller, or an electrical relay – this is the book that keeps your parts counter from becoming a return counter. I’ve been turning wrenches for 28 years, and I have seen more wrong parts come in on a Monday than I care to count. A catalog like this stops that nonsense.

What This Parts Catalog Covers

The manual covers four Toyota industrial vehicle models: 4FB20, 4FB25, 4FBJ20, and 4FBJ25. These are forklifts, not passenger cars. The systems included are broken into four major groups: Electrical, Chassis, Body/Electrical System, and Mast/Hydraulic System. Each group has its own figure index with illustrated exploded views. You locate the part in the drawing, read the part name code, and take that to your Toyota dealer. That’s the process.

Page 2 of the catalog shows the Quick Reference Index. It lists the frame number, lifting height, and descriptions like “Cold Storage Model Type 45S” and “Fully Oil Charged Lift Cylinder.” If your truck has optional equipment, you must specify the optional equipment code number when ordering. The catalog tells you exactly where those options appear in the DESCRIPTION field.

136 Pages – Factory Part Breakdowns by System

The content is organized by the TABLE OF CONTENTS from the original PDF. Here is exactly what you get:

• INTRODUCTION – General information on how to use the part name codes, frame numbers, and ordering process.
• FIGURE INDEX (1401-2611) – Electrical group – wiring harnesses, switches, controllers, lights.
• FIGURE INDEX (3305-4715) – Chassis group – axles, brakes, steering, wheels.
• FIGURE INDEX (5101-5801) – Body, Electrical group – cowl, seat, instrument panel, additional electrical components.
• FIGURE INDEX (6101-6802) – Mast, Hydraulic group – lift cylinders, tilt cylinders, hoses, mast rails.
• STANDARD TOOLS – A reference section listing service tools recommended for disassembly and assembly.

That is 136 pages dense with factory illustrations and part name codes. No fluff. No reprints.

Why You Need Factory Parts Data for Hydraulic and Mast Systems

Mast and hydraulic systems on these Toyota forklifts operate at high pressure. A wrong seal or an incorrect hose fitting can cause a catastrophic failure – dropped load, hydraulic fluid spray, or worse. The factory catalog shows the exact OEM configuration for every hose, fitting, and cylinder component. The figure index numbers (6101-6802) let you cross-reference your serial number with the correct parts. If you are rebuilding a mast or replacing a lift cylinder, this catalog is the only reference that matches the production line specifications.

I have seen shops try to use generic hydraulic parts catalogs and end up with a mast that drifts down. That does not happen when you order by Toyota part name codes. The dealer decodes your model number, frame number, and part code into a real part number. It works because the dealer has the same master data in their system.

Electrical System Diagrams – Figure Index 1401-2611

The electrical section covers everything from the main wiring harness to the ignition switch, alternator, and control modules. Figure Index 1401-2611 provides illustrations of each electrical component group. For example, the Cold Storage Model Type 45S has specific battery and wiring configurations that are not the same as a standard truck. The catalog lists those variations in the DESCRIPTION field below each figure. If you are troubleshooting an electrical fault on a 4FB20 or 4FBJ25, having the correct part breakdown saves you from ordering the wrong controller or switch assembly.

Keep in mind: this is a parts catalog, not a wiring diagram manual. You will not find voltage readings or test procedures. But you will see every connector, relay, and fuse panel exploded by figure number. That is exactly what you need when the dealer asks, “What is the part name code?”

Ordering Parts Correctly – Using the Part Name Code

The catalog does not list standard part numbers. Instead, it uses part name codes. These codes appear in the index of illustrations and in the text. On page 3, the GENERAL INFORMATION section explains in English, French, and Spanish how to order: specify the complete model number, engine model number, frame number, and part name code. Your Toyota dealer decodes that into a real part number. If you try to order “part number 12345” without the code, you will get the wrong item. This system exists because Toyota wants the dealer to verify fitment based on your specific vehicle configuration.

For any forklift with optional equipment, the DESCRIPTION field at the bottom of each page tells you which option codes apply. For example, a “Fully Oil Charged Lift Cylinder” has a different seal kit than a standard cylinder. The catalog forces you to verify that option code. That is a good thing. It prevents mistakes.

Frequently Asked Questions

Does this catalog include part numbers I can order directly?

No. It lists part name codes. You need to go through a Toyota dealer to decode the actual part numbers.

Can I use this to rebuild a 4FB20 engine or overhaul the mast?

This is a parts catalog, not a service manual. It will not give you torque specs, clearances, or rebuild procedures. What it does give you is the exact OEM breakdown of every part in the mast, hydraulic system, chassis, and electrical system. If you are rebuilding a mast, you need the figure index for the hydraulic group (6101-6802) to identify each seal, bushing, and cylinder component. Then you take those part name codes to your Toyota dealer and get the genuine parts. For the actual disassembly and reassembly steps, you will need the separate service repair manual for these models. Using this catalog alongside a service manual is the right approach – you get the correct parts and the correct procedures. I have done it many times.
