What's in it

It opens with general specs and engine data by application. The ratings change from an excavator to a loader to a truck, so check you're reading the right line. Then come structure and function, testing and adjusting, and disassembly and assembly. It finishes with the maintenance standards and repair.

It's a good fit for engine rebuilders and fleet shops that see this engine in more than one machine, and for mechanics chasing low power, smoke or hard starting.

Good to know

Before you strip an engine, it's worth running the tests in this book first. The checks in the testing chapter often show whether the problem is in the engine itself or in fuel, air or electrics around it. That can save a teardown. If it does need opening up, the service limits tell you which parts are still good. 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.

Before you buy

Check the engine plate. There are four variants in this family and the specs differ.
