TCM E835, E840, FD60Z8, FD70Z8, FD80Z8 Parts Catalog

I’ve seen too many guys order a piston ring set for the wrong engine because they didn’t have the factory parts catalog. Then they’re down a lift for a week waiting on the right parts. This 173-page TCM E835, E840, FD60Z8, FD70Z8, FD80Z8 Parts Catalog puts the OEM part numbers right in front of you. No guessing. You get exploded illustrations, part numbers, and the official abbreviations TCM uses. If you’re rebuilding the Isuzu 6BG1 diesel in one of these forklifts, you need this on your bench. The 173 pages cover every bolt, gasket, and seal in the engine – from the cylinder block to the injection pump.

Engine Families Covered: Six Isuzu 6BG1 Variations

The catalog breaks down ten engine codes from A-6BG1QC to A-6BG1QC09. Each code ties directly to specific machine models. For example, A-6BG1QC maps to the E835 and L16. A-6BG1TQC maps to E840 and L19. The FD60Z8 (both STD and GE) uses A-6BG1QC02. FD70Z8 (STD/GE) and FD80Z8 (EXA/EXA-GE) use A-6BG1QC03 and A-6BG1QC04? Actually the OCR shows A-6BG1QC03 for FD70Z8 EXA and FD80Z8 EXA. The catalog also covers US production variants and special equipment like large alternator (GE) specs. That level of granularity is why you pay for OEM documentation. Using the wrong part from a mixed-engine list can cost you a whole weekend.

How to Use This Catalog: From Contents to Part Number

Page 2 of the catalog (the Japanese instructions) and the English “How to Use” section explain the workflow. You know the part name? Look in the Contents, find the FIG number, then find the illustration. You know the assembly location? Same process. The catalog gives you the part number, shape, name, and record. Abbreviations like ASSY (assembled unit) and AR (as required) are defined on page 3. No aftermarket reprint will have this exact structure. If you skip the Contents step you’ll waste time flipping pages.

Why OEM Factory Documentation Beats Aftermarket Lists

Aftermarket reprints often have the wrong part number for a simple oil pan gasket. The OEM TCM catalog is the only source that matches the exact part number to the engine serial number. The engine number is punched on the cylinder block under the oil filler port. The machine serial number is on the nameplate. Cross-referencing both is the only way to guarantee the part fits. Third-party catalogs guess. This one doesn’t. When safety components like fuel lines or brakes are involved, the wrong part can cause a fire or loss of control. Don’t gamble.

Ordering Parts: The Process That Keeps Your Machine Running

When you order from a dealer, you need the model, serial number, engine type, serial number, and part numbers. This catalog gives you all that. It also notes which parts are sold as sets or kits (marked with *), and which are not sold separately (marked with #). If you need a parts breakdown for the FD60Z8 or FD70Z8, the exploded views show every bolt, seal, and gasket. That saves you from ordering a full assembly when you only need a seal. Have the part number in hand before you pick up a wrench – it keeps the machine safe and your wallet intact.

7 Systems Illustrated in the Catalog

The catalog covers the complete diesel engine – cylinder block, cylinder head, fuel system, lubrication, cooling, intake/exhaust, and electrical. Each system has its own FIG number. For example, the cylinder head section includes valve train components, gaskets, and bolts. The fuel injection system includes the injection pump, nozzles, and lines. You get the factory drawing and the part number list next to it. No translation errors. That’s the difference between a correct rebuild and a parts-finding nightmare.

FAQ

Does this catalog include torque specifications for cylinder head bolts?

No. This is a parts catalog, not a service manual. Torque specs are found in the factory service manual.

How do I find the correct part number for my engine?

Start by locating your engine serial number stamped on the cylinder block near the oil filler port. Then open the catalog’s Contents section to find the FIG number that matches your engine model. Each FIG shows an exploded illustration with callouts. Cross-reference the callout number with the parts list to get the OEM part number. The catalog also includes abbreviations like ASSY for assembled unit and AR for as required. Always verify your machine serial number as well because some parts vary by production stage, like US production models listed under A-6BG1QC05S. Use this process every time to avoid ordering the wrong component.

Ordering parts for a TCM forklift without this catalog is like pulling a head bolt torque out of thin air. You’ll get it wrong. Access the Factory Manual and keep it on your tablet or printed out. Your wallet and your downtime will thank you.
