Mitsubishi FD135 Forklift Service Manual (99799-70110)

A Mitsubishi FD135 is a big diesel counterbalanced yard truck, the kind you see loading flatbeds and stuffing containers. When one of these is down, people reach for the service manual so they're not guessing on teardown, pressures, or adjustments. Around my shop, this is what we use when we're into the engine, transmission, steer axle, or chasing a hydraulic or electrical fault that won't show itself.

What this manual helps you do

• Trace and diagnose hydraulic issues in lift, tilt, and auxiliary functions on the FD135.
• Check, adjust, and repair the diesel engine and cooling system on this specific truck size.
• Follow teardown and reassembly steps for the powershift transmission, drive axle, and brakes.
• Diagnose and repair electrical problems using the wiring diagrams and connector callouts.
• Set and verify steering, mast, and brake adjustments after major component work.

Who this is for

This is aimed at warehouse or plant maintenance techs, dealer and independent forklift shops, and rental fleet mechanics who are actually wrenching on an FD135. If you just need to know how to drive it or what the warning lights mean, you want the operator's handbook, not this.

FAQ

Q: What format is it in and how readable are the diagrams?

A: You get 51 PDF files, scanned page images with no text search. They zoom and print fine, including the wiring diagrams.

Q: Will this cover my exact truck?

A: It's for Mitsubishi FD135 trucks in the F15C-50083 and up serial range. If your plate shows FD135 with an F15C serial at or above that, you're in the right place.

Q: Is this the right document if I'm doing my own repairs?

A: Yes, this is the workshop service manual, not parts and not ops. It's what you want for real repair work on an FD135.

Bottom line, if your truck is an FD135 in that F15C-50083-up range and you're fixing it yourself, this is the manual you want. If the model or serial doesn't match, skip it.
