What's in it

It covers the CLSS load-sensing hydraulics, the pump, the control valve, the PPC valves and the swing and travel motors. Testing and adjusting includes engine checks for both the 3D84E and the 4D84E. After that come removal and installation of the main components, and the maintenance standards and wear limits.

Landscapers, utility crews and rental fleets use these minis hard. The book helps with weak or slow hydraulics, travel motor problems, swing drift and worn pins and bushings.

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.
