Mitsubishi FB16KT, FB18KT, FB20KT Service Manual – Factory Specs for Forklift Repair

If you’ve ever tried to rebuild a forklift mast cylinder using a generic manual that tells you “tighten to spec” without giving you the actual number, you know the frustration. That’s why I tell every new hire in my shop: get the factory manual or walk. This Mitsubishi FB16KT, FB18KT, FB20KT Service Manual is exactly that — the real OEM documentation from Mitsubishi, not some aftermarket reprint that guesses at torque values.

Mitsubishi FB16KT, FB18KT, FB20KT Service Manual: Factory Content Overview

Page 3 of this 300-page manual lays out the safety symbols used throughout. Mitsubishi doesn’t mess around with warnings — they have separate symbols for risk of death, machine damage, and shortened service life. Page 4 shows the disassembly sequence format: each exploded diagram comes with a numbered removal order and clearance limits in millimeters. You get the standard clearance (A) and the repair limit (B). That’s the kind of data you need when you’re measuring piston-to-cylinder bore wear.

Safety Warnings and Symbols

Before you drop the mast, read the preface. It tells you to lower forks to the ground and block them before any work. I’ve seen guys skip this and almost lose a foot. The manual uses three symbols: AVVERTENZA (danger), ATTENZIONE (caution), and NOTA (note). You ignore them at your own risk. This isn’t a suggestion — it’s the factory’s warning system.

Disassembly Sequence and Fitment Data

The manual groups instructions by system — frame, mast, and options. Each section starts with an exploded view and a sequence list. For example, removing the output shaft is step 2 in the disassembly order. Then you get the fitment data: standard clearance 0.020–0.105 mm, repair limit 0.15 mm. If you’re rebuilding a mast tilt cylinder, you need those numbers to know whether to replace or reuse. Aftermarket manuals often round them or skip them.

Why a Factory Manual Beats Aftermarket

I’ve seen aftermarket manuals that list torque specs for bolts that don’t even exist on the actual truck. They copy from a different model and hope it fits. Mitsubishi’s factory manual is specific to the FB16KT, FB18KT, and FB20KT — serial numbers EFB4A-00011 and later, EFB5A-00011 and later, EFB5A-50001 and later. That means the mast geometry, hydraulic routing, and bolt grades are correct. You pay for that certainty. Mitsubishi FB16KT FB18KT FB20KT Service Manual | Factory Specs is the one you want.

300 Pages: What You Get

300 pages cover the chassis, mast, and options. The manual is meant to be used with the separate controller service manual (page 1 mentions this). So if you need the drive controller diagnostics, you’ll need that companion book. But for mechanical work — mast disassembly, hydraulic cylinder rebuilds, steering gear, brake adjustments — this manual has everything. It includes the pub. no. 99719-56B00, which matches Mitsubishi’s official distribution.

One thing I appreciate: the manual is printed in Italian. That doesn’t matter for the technical data. Torque values are numbers, clearances are numbers. The diagrams are self-explanatory. If you can read a micrometer, you can use this manual.

Frequently Asked Questions

Is this manual in English?

The original text is Italian. But the diagrams and specs are universal. You read numbers and torque charts just fine.

Does this manual cover the controller?

This manual covers chassis, mast, and options only. The controller section is a separate manual (page 1 says ‘Per l’uso con il manuale di servizio del controller’). That means if you need the electrical system troubleshooting, you must have that companion manual. Many aftermarket sellers bundle them, but here we sell only the chassis manual. You’ll need the controller manual for the drive and pump controllers, the wiring diagrams, and the diagnostic trouble codes. The mast section in this manual includes disassembly specs, torque values for the lift cylinder, and mast tilt adjustments. Without the controller manual, you cannot diagnose a traction fault. So plan on getting both.

What years does this cover?

Serial numbers starting EFB4A-00011 and later. No publication year listed, but it’s current for those chassis.

Can I use this for a different Mitsubishi forklift model?

No. It’s specific to FB16KT, FB18KT, FB20KT. Other models have different mast configurations and hydraulic pressures.

If you’re working on one of these Mitsubishi forklifts, you need the factory data. Don’t trust a third-party manual that guesses at mast bearing preload or hydraulic pressures. Access the Factory Manual and get the specs that Mitsubishi engineers put in.
