Komatsu PC15R-8 Mini Excavator Shop Manual (WEBM002800)

WEBM002800 is the shop manual for later PC15R-8 mini excavators. It's a working book for a small machine: how the load-sensing hydraulics behave, how to test them, how to get components out and what they should measure.

Fits

PC15R-8 from serial F21803. Earlier PC15R-8s are covered by SEBM013103 (serial 10001 and up) or WEBM000100 (serial F20001 and up), both in our catalog. The engine test data is for the 3D68-N3FBE three-cylinder.

Quick facts

• Manual Number: WEBM002800

• Serial: F21803 and up
• Engine: 3D68-N3FBE
• Hydraulics: CLSS load sensing
• Format: PDF, 236 pages

What's in it

The structure and function chapter covers the CLSS load-sensing system, the variable displacement pump, the control valve, the PPC valves, the swing and travel motors and the cylinders. Testing and adjusting has the engine checks, the hydraulic pressures, the travel and swing speeds and the troubleshooting tables. Removal and installation covers the major components. The maintenance standards at the end give you the wear limits.

There's no separate general specifications section. The book starts at section 10.

Mini excavators like this get worked hard and serviced in a hurry. If you own one, rent them out, or fix them for a living, this gives you the numbers to check a weak boom, slow travel or a swing that drifts, without stripping things blind.

Table of contents

Good to know

Most people use a book like this one section at a time. Look up the system that's giving trouble, read how it's meant to work, test it against the standard values, and only then order parts. That order saves money, because a reading that's close to spec usually points somewhere other than the part you suspected first. You can print the pages for the job and keep the PDF on a tablet for everything else.

Before you buy

Three different manuals cover the PC15R-8 depending on serial, so match yours to F21803 and up before buying.
