Mitsubishi FD135N Forklift Service Manual (99799-53100)

This FD135N is a big diesel counterbalance truck, the kind that lives on the dock, in the yard, and loading flatbeds all day. The service manual is what you reach for when one is down in front of a dock door and you've got freight backing up, or when you're doing planned work on engine, transmission, or hydraulics between shifts. You use it to get the right specs, wiring info, and teardown steps so you only pull it apart once and it goes back into the aisle ready to work.

What this manual helps you do

• Diagnose engine, fuel, and cooling problems on the FD135N using proper checks and factory specs
• Trace and repair electrical and charging issues using wiring diagrams and connector callouts
• Follow step-by-step procedures to remove, inspect, and reinstall the powershift transmission and drive axle
• Rebuild or reseal hydraulic components, then pressure-test and adjust reliefs and control valves
• Check, adjust, and replace steering, brake, mast, and carriage components to factory tolerances

Who this is for

This is for anyone actually wrenching on a Mitsubishi FD135N: warehouse or plant maintenance, dealer techs, independent shops, and rental fleet mechanics. If you just need operating instructions or daily checklists, you want the operator's handbook, not this service manual.

FAQ

Q: What format is it in, and can I search it and read the diagrams?

A: It's a set of 27 PDF files with a real text layer, so you can search and copy text. Wiring and hydraulic diagrams are included and readable on screen or printed.

Q: Will this cover my truck's serial number?

A: It's for FD135N trucks in the F15D-60011-up range. If your plate shows FD135N and a serial in that range or higher, this is the right one.

Q: Is this the right document if I'm planning major repairs?

A: Yes. This is the workshop-level service manual for teardown, diagnostics, and adjustment, not a parts book or safety/operation booklet.

Bottom line: If you're maintaining or repairing an FD135N in the F15D-60011-up range, this is the manual you want. If you're after basic operation only, it's overkill.
