This factory service and repair manual for the 1983 Chevrolet B60 documents the cab forward school bus in its single B6P042 designation, along with the five power units listed against it: the naturally aspirated 6.0L OHV, 7.0L and 5.7L gasoline V8s and the 8.2L V8 diesel in turbocharged and naturally aspirated form. Two fuels and three gasoline displacements make the engine chapters the longest part of the book, while the chassis, brake, steering and electrical chapters that follow apply to every bus whatever is fitted.

Known issues on the 1983 B60. No recall stands against this bus and no owner complaint has been registered with NHTSA. The manual is written for the people who keep it in service rather than for anyone chasing a campaign repair. Each of the five engines is documented with its own procedures, specifications, torque values, wiring diagrams and diagnostics, and the cab forward chassis is covered the same way, so a coolant leak, a charging fault or a brake overhaul can all be worked through from a single reference.
