Nichiyu FBT13, FBT15, FBT18, FBT10 1992 Technical Manual

If you’re working on a Nichiyu FBT series forklift and you don’t have the factory manual, you’re working blind. I’ve had to redo jobs because a tech used an aftermarket spec that was off by 5 ft-lbs. On a hydraulic fitting, that’s a leak waiting to happen. This 1992 technical manual for the Nichiyu FBT13, FBT15, FBT18, FBT10 1992 Technical Manual gives you the exact numbers the guys in Kyoto used when they built these trucks. It’s 105 pages of Japanese engineering, translated into straight talk for the shop floor.

Model Coding System and Name Plate: What Each Letter Means

Page 2 of the manual walks you through the model coding system. You see “FBT18-50P” stamped on the frame? The “BT” stands for three-wheel, the “P” for pneumatic tires. The manual has a table that breaks down every suffix: C for cushion, PN for pneumatic solid, B for large battery, D for electrical enclosure. If the name plate is worn, you use this section to identify the truck from the serial number. Skip this step and you could order the wrong mast bearings or pump seal. That’s a half-day of wasted labor.

Serial Number Locations: Finding Your Truck’s Birth Certificate

Every component has a serial number location. The manual shows where to find them on the frame, drive unit, and hydraulic pump. When you’re ordering parts from the dealer, they’ll ask for the serial number. This section, as part of the General chapter, tells you exactly where to look. No guessing. No crawling under a dusty frame for an hour. The manual covers FBT10, FBT13, FBT15, and FBT18 models. If you’ve got one of these, the location diagrams are the same platform.

Specifications: Fluid Capacities and Dimensions

The specs table on page 4 lists everything from tire size to travel speed. You need the hydraulic tank capacity for an FBT15? It’s there. The battery weight for an FBT18? Listed. This is the data you reference when swapping a pump or charging the system. I’ve caught guys overfilling the gearbox because they used a generic spec from another model. That costs seals. The manual gives you the exact Imperial pints and quarts. Trust that data, not the guy who says “that looks about right.”

Stability and Load Chart: Non-Negotiable Safety Data

The manual includes a section on truck stability and load charts. Page 5 covers this. If you’re modifying the forklift – adding a side shift, changing the tire type – you need to verify the load center remains within spec. The factory chart shows the safe operating envelope. I’ve seen a forklift tip because a tech swapped pneumatic tires for cushion tires and didn’t check the stability diagram. That’s a lawsuit waiting. The manual gives you the original stability data. Use it.

Nichiyu FBT13, FBT15, FBT18, FBT10 1992 Technical Manual: Inside the 105 Pages

Beyond the general section, this technical manual covers the entire machine: electrical schematics, hydraulic circuit diagrams, brake adjustments, and steer axle service. It’s not a repair manual with step-by-step rebuilds – it’s the technical foundation. You use this alongside the service manual for torque values, clearances, and wiring pinouts. For example, the manual lists the tightening torque for the wheel nuts, which on an FBT18 can mean the difference between a cracked rim and a secure ride. I’ve seen aftermarket manuals list the wrong thread pitch. This one is direct from Nippon Yusoki Co., Ltd. (NICHIYU). That’s the OEM source. No reprints, no third-party copy. Page 1 shows the publication number 92W-2101 and December 1992 date. If you want a counterfeit, go somewhere else.

For reference, check NICHIYU FBT13 FBT15 FBT18 Technical Manual if you need the sister document for different model years. Nichiyu FBT13, FBT15, FBT18, FBT10 Troubleshooting Manual covers common faults. Nichiyu FB-60 SERIES FB10-30P Technical Manual is for the larger series but shares some platform architecture. And if you’re brushing up on drivetrain theory, Manual Transmission basics are helpful, but this manual gives you the actual adjustments.

Period.

A: Yes. The specifications section lists tightening torques for major fasteners, including mast anchor bolts. Refer to page 4 of the manual for the exact values. Do not use generic torque charts – the bolt grade on these Japanese trucks is specific.

Q: Is this manual in English?

A: Yes. It’s a factory English translation, published for the North American market.
