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 gives the standard values, pressure checks, adjustments and troubleshooting.

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

WA150s are handy all-rounders on farms, in councils and in landscaping. HST drive and brake issues come up most, and the pressure checks here let you narrow down the cause before buying parts.

Good to know

If you're new to Komatsu manuals, the layout takes a few minutes to learn and then saves a lot of time. Each system is covered in the same order: how it works, the values it should meet, how to test it, and how to take it apart. Search works on most pages, and printing one procedure for the job keeps the rest of the book clean.
