What's in it

It begins with general specs, weights and dimensions. The structure and function chapter covers the hydraulic pumps and pump control, the control valve, swing, travel and electrical system. Testing, adjusting and troubleshooting gives you the pressures and settings and the diagnosis tables for hydraulic and electrical faults. Disassembly and assembly follows, then the maintenance standards and wear limits.

Contractors and fleet shops still running -6 generation excavators will use it for slow or weak hydraulics, swing and travel problems, pump control faults, and pin, bushing and undercarriage wear.

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. 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.
