Bosch Rexroth A10VSO Series 30 Hydraulic Pump Service Manual

The A10VSO Series 30 is a variable displacement axial piston pump. On a crane or other heavy machine, it supplies the oil flow and pressure that drive the hydraulic functions. When one starts to lose pressure, leak at the drive shaft or respond badly to its controls, a fleet mechanic or independent shop reaches for the service manual. The goal is to repair it in-house and get the machine back on the job. The cover may carry the older brand name Mannesmann, so don't let the logo surprise you. This is the complete Bosch Rexroth manual, and it is used on Franna machines.

What this manual helps you do

• Rebuild the pump by following the disassembly sequence and the assembly dimensions.
• Replace the drive shaft seal using the sealing the drive shaft procedure.
• Identify the right seal kits and sub-assemblies from the cross section.
• Clean and inspect the pressure and flow control, including the pilot valves.
• Set up and verify the pump using the testing and set up instructions.

Who this is for

A rental fleet mechanic or crane service technician who is repairing pumps in-house will get the most from it. It also suits independent repair shops and dealer technicians who need a rebuild reference with tools and tightening torques in one place.
