Hino RB 14 Workshop Manual – 266-Page OEM Service Document

Description

I’ve been turning wrenches since before most of you were born. 28 years as an ASE Master Technician, and I’ve seen more head bolts than hot meals. If you’re working on a Hino RB 14 bus chassis, you need a manual that doesn’t guess. This is the factory OEM workshop manual – Hino RB 14 Workshop Manual – 266 pages of what Hino actually uses at the plant. No aftermarket rehash. No missing torque specs. Just the real deal.

Clutch and Clutch Control – Factory Procedure

The clutch section starts on page 2 of the index. It covers the full clutch assembly, including the clutch control linkage. You get disassembly, inspection, and reassembly procedures with Hino’s own limits. If you’re replacing a clutch on an RB 14, you need the correct pedal free play and release bearing clearance. The manual gives you those numbers. Don’t trust aftermarket charts.

Transmission and Propeller Shaft: What the Manual Covers

Transmission is a separate chapter. The manual covers the transmission assembly and the control mechanism. Propeller shaft section follows. For a bus, driveline angles and U-joint phasing matter. The manual includes runout limits and torque specs for the flange bolts. Refer to Manual Transmission basics if you need background, but this manual gives you the Hino-specific data. Page 2 lists the Transmission and Transmission Control chapters under Chassis Group 1/2.

Does the Manual Cover the Brake and Suspension Systems?

Yes. The Service Brake and Parking Brake sections are both in Chassis Group 1/2. You’ll find air brake system troubleshooting, lining wear limits, and brake adjustment procedures. The Suspension chapter is in Chassis Group 2/2. It covers leaf spring inspection, shock absorber service, and U-bolt torque. Page 5 shows the index for Chassis Group 2/2, including Suspension and Chassis Frame. If you’re doing a brake job, you need the correct torque for the chamber mounting bolts. It’s in there. The brake section includes detailed bleeding procedures for hydraulic systems, air dryer replacement intervals, and composite brake shoe wear limits. For the suspension, the manual gives you the exact tightening sequence for the spring U-bolts – a step many aftermarket manuals skip. Without that sequence, you can warp the spring seat. The chassis frame section covers rivet replacement and frame rail inspection. All of this is specific to the RB 14 series. That’s why a factory manual is non-negotiable.

Hino RB 14 Workshop Manual – Why OEM Documentation is Critical

Aftermarket manuals leave out critical details. I’ve seen techs use generic torque values and snap fasteners. This manual comes direct from Hino Motors, Ltd. Printed in Japan in December 1986. It’s the same book the dealership used. The Electrical Equipment section covers wiring diagrams, component locations, and testing procedures for the bus’s electrical system. Without that, you’re chasing shorts with a test light. The manual also includes the Recommended Lubricant section – which fluid goes where. Don’t guess. Use the factory specs.

Electrical Equipment and Recommended Lubricant: Torque and Specs

Page 5 shows the Electrical Equipment chapter is included. The manual covers the entire bus electrical system – from battery and starting circuits to lighting and accessories. For the transmission, clutch, and brake systems, every fastener has a specified torque. The Differential Carrier section gives pinion bearing preload and ring gear backlash. The steering and power steering chapters include adjustments. For further reading on transmission types, see Manual Transmission on Wikipedia.

Can I use this manual for engine repair on the RB 14?

No, the foreword states engine service requires a separate manual (W04C-T engine reference).

Does the manual include torque specifications for the suspension and brake systems?

Yes. The manual covers every chassis system with factory torque values. For example, the Suspension chapter gives leaf spring U-bolt torque, and the Service Brake chapter includes chamber mounting bolt torque and slack adjuster specifications. The Differential Carrier section provides pinion bearing preload and ring gear backlash. These are not generic numbers – they are Hino’s own specs. Using aftermarket values risks component failure. The manual also lists fluid capacities and types in the Recommended Lubricant section. So if you’re rebuilding a brake system or suspension, you have the correct data.
