Bosch Rexroth A2FM Hydraulic Motor Service Manual

The A2FM is an axial piston hydraulic motor. On a crane or heavy machine it turns hydraulic flow into rotation for drives like the slewing gear, winch or travel system. When one starts leaking, losing speed or making noise, the person reaching for this manual is a technician who needs to pull it, rebuild it or replace it and get it back in service. This manual is used on Liebherr machines.

What this manual helps you do

• Follow the removal and installation steps to take the motor off the machine and refit it correctly.
• Rebuild the motor by working through disassembly and assembly in the right order.
• Check worn internal parts against the inspection and adjustment guidance before you reassemble.
• Adjust the motor after repair so it is ready to go back on the machine.
• Troubleshoot a motor that has lost performance by starting from the description and function of the unit.

Who this is for

A crane service technician or rental fleet mechanic who repairs hydraulic components in-house will get the most from it. It also suits an independent repair shop or a dealer technician who has a motor on the bench and needs a procedure to follow instead of guessing.
