This factory service and repair manual for the 1986 Chevrolet B60 lists five engines and a single body: the naturally aspirated 6.0L OHV and 5.7L gasoline V8s, the turbocharged 14.0L inline-six diesel, and the turbocharged and naturally aspirated 8.2L V8 diesels, all in the cab forward school bus designated B6P042. Three diesels against two gasoline V8s changes the balance of the book, with injection, air intake and diesel fuel diagnostics taking up more of it than ignition work does.

Known issues on the 1986 B60. The federal record shows no recall for this bus and no complaint from any owner. The manual therefore serves as reference rather than remedy, and with three diesels and two gasoline V8s it carries a great deal of it. Every engine is given its own procedures, specifications, torque values, wiring diagrams and diagnostics, and the cab forward chassis is documented across frame, suspension, driveline, brakes, steering and the body electrical system.
