Toyota 8FG35U, 8FG40U, 8FG45U, 8FG50U, 8FG60U Repair Manual

I’ve seen too many guys try to chase a no-start on a forklift with a generic aftermarket PDF that lists the wrong injector timing. That costs billable hours and parts you can’t return. This Toyota 8FG35U, 8FG40U, 8FG45U, 8FG50U, 8FG60U Repair Manual is the actual factory document. 674 pages. Published under Toyota’s own part number CE104. If you work on these forklifts, this is what you need on the bench.

Engine Overhaul and Diagnostics

Chapter 1 of this manual (page 34) digs into both the 1FS gasoline/LPG engine and the 1KD diesel. You get the full “Inspection and Adjustment” procedures for each. That means idle speed, compression, oil pressure, V-belt tension, plus everything from crank angle sensors to glow plugs. For the 1FS engine, there’s separate sections for gasoline and LPG fuel systems. The LPG regulator overhaul has dedicated SSTs and a tamper-proof ring procedure. If you’re bleeding a diesel fuel system, the steps are right there under “Air Bleeding of the Fuel System (Diesel Vehicle).” No guesswork.

Torque Specs and Fluid Capacities

Right in the GENERAL section, Toyota gives you a standard bolt and nut tightening torque table, high-pressure hose fitting torque, and a bolt strength identification method. That table is worth its weight in busted knuckles. You also get recommended lubricant quantity and types, a lubrication chart, and the periodic maintenance schedule. Page numbers aren’t everything, but the torque converter and transmission section (Chapter 2) has its own troubleshooting and hydraulic circuit diagram. You want the torque for the propeller shaft? It’s all in Chapter 3. The differential and axle chapters (4–6) give you the factory spec on ring gear bolts and bearings.

Suspension and Axle Procedures

Front axle is Chapter 5, rear axle is Chapter 6. The manual covers removal, disassembly, inspection, and reassembly for both. If you’re rebuilding a steer axle on a 8FG40U, you need those bearing preload specs and kingpin torque values—this manual has them. The suspension geometry is laid out with actual measurements, not a “refer to local dealer” note. I’ve used these chapters to get a lift truck back on its wheels without sending it to the dealership.

Why You Need Factory OEM Pages

Aftermarket manuals copy the cover and miss the details. This one is scanned from the actual Toyota publication. The wiring diagrams, the LPG regulator troubleshooting, the 1KD common rail inspection—none of that comes from third-party churn. If you’ve ever fought a wrong torque spec on a wheel nut, you already know the cost. This manual gives you the official tightening torque table. That’s not a suggestion; it’s the spec Toyota designed the lift truck to.

Does This Manual Cover the Fuel System?

Yes. The “1FS Fuel Pump” remoavl and installation, fuel sender gauge, LPG main solenoid and filter, injector inspection—all there. For the 1KD, you get the supply pump, common rail, and electric EGR valve. The section on “Air Bleeding of the Fuel System (Diesel Vehicle)” is a lifesaver if you’ve ever caused a shop fire by cranking too long without a clear line.

Q: How do I find the correct torque for the differential ring gear bolts?

Look in Chapter 4 (Differential) under the assembly section. The tightening torque table in the GENERAL section also lists standard bolt torque by strength grade. Use the bolt strength identification method on page 1 to confirm you have the right grade.

Q: Is this manual only for 8FG60U?

No. It covers 8FG35U, 8FG40U, 8FG45U, 8FG50U, and 8FG60U. Also includes 8FD and 8FGC variants. Check the foreword for the full list.
