What's in it

After the specs, weights and capacities, the structure and function chapter covers the torque converter, the transmission with its ECMV valves and automatic shift, the axles, brakes and steering. That's followed by the work equipment hydraulics and the electrical system. The testing, adjusting and troubleshooting chapter is where to go for shift complaints, brake problems or slow hydraulics. Disassembly and assembly of the major components comes next, and the maintenance standards give the wear limits.

Quarry and yard loaders like this work long shifts, and transmission and brake faults are the expensive ones. The ECMV section is worth having on its own, because electronically controlled shifting can be hard to diagnose without the factory test procedure.

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.
