Mitsubishi FD45NB Forklift Service Manual (99739-5B110)

This FD45NB is a mid-size diesel counterbalance truck that lives on docks, yards, and rough plant floors, loading trailers and feeding production. The people who grab this service manual are the ones who get called when it won't start, won't lift, or is due for a big service before it goes back on rent. They're trying to get torque specs, pressures, and step-by-step procedures so the truck goes out tomorrow without coming right back on a hook.

What this manual helps you do

• Diagnose hard-start, low-power, or smoking issues on the diesel engine and fuel system
• Trace, check, and repair electrical faults using wiring diagrams and connector pinouts
• Follow teardown and reassembly steps on the powershift transmission, steer axle, and drive axle
• Adjust mast, chains, and hydraulic valves to fix slow lift, drift, or side-shift problems
• Troubleshoot brake and steering problems, then verify everything with the right test specs

Who this is for

This is aimed at dealer techs, independent forklift shops, plant maintenance, and rental fleet mechanics who already know their way around a lift truck. If you just need operating instructions or daily checks, you want the operator's handbook, not this manual.

FAQ

Q: What format is it in? Can I search it and read wiring diagrams?

A: You get 40 PDF files split by section, with a real text layer, so they're searchable. The wiring diagrams are clear enough to zoom in and follow circuits.

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

A: It's written for FD45NB trucks in the CF19F-50001-79999 serial range. If your plate is outside that, this may not match everything.

Q: Is this the right document for basic parts lookup?

A: No, this is a workshop repair manual. For part numbers, you'd still want the separate parts catalog.

Bottom line: If you're repairing or overhauling an FD45NB in that serial range, this is the right manual. If you're after basic operation or parts lists, it isn't.
