1976 Yamaha RD400 Service and Repair Manual

One part number covers the whole RD400 run: LIT-11616-RD-40, written for 1976 through 1979. The 1976 machine is the RD400C, and that code appears in the specification tables wherever the years differ.

Yamaha changed details across those four seasons, and a single manual handling all of them is an advantage rather than a shortcut. When a figure or a procedure is specific to the C model the book says so; where it is common to the whole range the text is written once.

Main chapters

• Periodic maintenance, adjustment and tune-up specifications
• Engine removal, top end, crankshaft, clutch and six-speed gearbox with torque values
• Autolube, carburettor and ignition service
• Frame, forks, swingarm, wheels and brakes with wear limits
• Wiring diagrams and electrical troubleshooting
