Liebherr R 934 C and R 944 C Excavator Service Manual

Liebherr R 934 C and R 944 C excavators dig, load and move material on quarry floors, utility trenches and demolition sites. When one goes down out of warranty, the person with the wrench needs workshop procedures, not guesswork. That's usually a shop tech or fleet mechanic who is about to pull a pump, a swing drive or a final drive and wants the right steps in front of them. This manual covers the R 934 C, R 944 C and R 954 C in one document.

What this manual helps you do

• Diagnose hydraulic system faults using the hydraulic system and hydraulic components sections.
• Trace wiring and check circuits with the electrical system section.
• Rebuild a swing gear or swing ring, or replace travel gear and track components.
• Follow the diesel engine and coupling_splitterbox procedures when removing or servicing the drivetrain.
• Verify settings against the technical data section, and find the tools you'll need in the tools section.

Who this is for

A dealer technician, independent repair shop or rental fleet mechanic who repairs these excavators in-house. It also suits plant maintenance staff who keep a Liebherr machine running and want the workshop procedures on hand.
