What's in it

It starts with general specs and performance curves for each machine, which is useful because output varies by application. Structure and function comes next, then testing, adjusting and troubleshooting. Disassembly and assembly covers the teardown, and the last chapter is the maintenance standards and repair.

Rebuilding a V12 this size is a big, costly job. Most of the value in the book is in the maintenance standards, which tell you which parts can go back in and which must be replaced.

Mine and quarry engine shops and specialist rebuilders will use it the most. Removing the engine from the loader is covered in the machine's own shop manual.

Good to know

Engine shops tend to keep a book like this open beside the stand for the whole job. It has the clearances, the torque values and the assembly order in one place, so there's no guessing at a figure. The specs are set out by engine model, so check you're reading the line for your engine before you measure anything.
