What's in it

After the general specs and fluids, section 10 covers structure, function and maintenance standards for the HST pump and motor, axles, differentials, steering (Orbit-roll and emergency steering), brakes, hydraulics, PPC valves, work equipment and electrical. Section 20 covers testing and adjusting, with the standard values, checks, adjustments and troubleshooting.

Section 30 covers removal, installation and rebuild of the main components, and section 90 has the circuit diagrams.

PZ loaders often do pallet and attachment work in yards and farms. The parallel-lift linkage has its own pins and bushings to look after, and the work equipment pages cover them.

Good to know

A tip from shops that use these books every day: read the structure and function pages for a system before you start testing it. Knowing how the valves and circuits are meant to work makes the test results much easier to read. The standard values then tell you whether a reading is normal, borderline or out of spec, and the wear limits decide whether a part goes back in.

Before you buy
