ZF Servocom 8090-8099 Steering System Service Manual

The ZF Servocom steering gear is a hydraulic power steering unit. It turns the driver's wheel input into steering force at the axle on heavy machines, and it's used on Liebherr machines. Techs reach for the service manual when a steering gear leaks, binds, wanders or needs to come off the machine for a rebuild. It's the book you open at the bench.

What this manual helps you do

• Check how the steering gear works, from the operation and design and function sections, before you start pulling parts.
• Set the hydraulic steering limiter using the function and setting procedure.
• Follow the maintenance, oil filling and bleeding steps after a repair or a fluid change.
• Replace the pressure relief and replenishing valves using the removal and re-assembly instructions.
• Diagnose steering faults with the troubleshooting section, then verify parts against the inspection instructions.

Who this is for

An independent repair shop or rental fleet mechanic who has a Servocom steering gear on the bench or on a machine that's out of warranty. Also a crane service technician or plant maintenance crew who needs the removal, fitting and troubleshooting steps in one document.
