Mitsubishi FD55N Forklift Service Manual (99739-57300)

This Mitsubishi FD55N is a mid-size diesel counterbalance truck you'll see loading flatbeds, stuffing containers, and living on docks and yards. The service manual is what you pull when the truck is down and you need it turned around without guessing. Around my shop, this is the book you use for real repairs, not daily checks: chasing hydraulic leaks, engine issues, or drive-line problems so the machine can go back out tomorrow.

What this manual helps you do

• Diagnose hard-start, smoke, or power loss on the diesel engine and follow step-by-step repair procedures
• Trace electrical faults using wiring diagrams and check circuits with a meter instead of shotgunning parts
• Rebuild or replace hydraulic components, then set and verify pressures so the mast and hydraulics behave properly
• Adjust the powershift transmission, differential, brakes, and steering so the truck tracks straight and stops right
• Troubleshoot fault symptoms using service data, then confirm fixes with the correct test points and specs

Who this is for

This is for a warehouse or plant maintenance tech, dealer technician, independent forklift shop, or rental fleet mechanic who is actually tearing into an FD55N. If you just need operating instructions or safety info, you want the operator's handbook, not this service manual.

FAQ

Q: What format is it in, and can I search it or read wiring diagrams clearly?

A: It's a multi-file PDF set split by section, with a real text layer, so you can search and zoom wiring and hydraulic schematics cleanly.

Q: Will this cover my FD55N by serial number?

A: It's written for FD55N trucks in the EF28C-80001 serial range; if your plate matches that prefix, you're in the right place.

Q: Is this the right document if I'm planning in-house repairs?

A: Yes, this is the workshop-level service manual, not a parts list or quick-start guide.

Bottom line: If you're maintaining or repairing an FD55N in the EF28C-80001 range, this is the correct service manual. If you only need parts numbers or basic operation, it's the wrong book.
