ZF Servocom 8096 and Servocom 8099 Steering System Service Manual

The ZF Servocom is a hydraulic steering gear. On Liebherr machines it turns the driver's input into steering force at the wheels, with a pressure relief and replenishing valve setup and a hydraulic steering limiter built in. The people who reach for this manual are the ones pulling the gear off a machine to rebuild it, set the limiter, or chase a steering fault when there's no warranty backing the job.

What this manual helps you do

• Follow the removal and fitting procedures for taking the steering gear off the vehicle and putting it back.
• Set the hydraulic steering limiter using the function and setting instructions.
• Replace the pressure relief and replenishing valves with the removal and re-assembly steps.
• Check parts against the inspection instructions before you close the unit up.
• Troubleshoot steering faults with the troubleshooting section, then bleed the system after oil filling.

Who this is for

Independent repair shops, rental fleet mechanics and crane service technicians who work on Liebherr machines with a Servocom steering gear. If you're rebuilding the unit in-house, it's the workshop reference for the job.
