Liebherr R 974 C Excavator Service Manual

The R 974 C is a tracked excavator that digs, loads trucks and moves material on quarry, demolition and earthmoving jobs. When one goes down, the person under it is usually a shop mechanic or fleet technician who needs repair steps and test procedures, not guesses. That's what a service manual is for.

What this manual helps you do

• Troubleshoot the hydraulic system, from pump and valve problems to slow or weak functions.
• Rebuild hydraulic components using the disassembly and repair procedures a service manual like this usually gives.
• Trace faults in the electrical system and check circuits against the wiring and test information you'd expect to find.
• Replace and adjust parts on the diesel engine and the swing ring.
• Verify central lubrication operation and check special attachment setups.

Who this is for

Independent repair shops fixing out-of-warranty excavators in-house. Rental fleet mechanics and plant maintenance crews will also get use from it. So will dealer technicians who want the workshop procedures at the bench or in the field.
