Series 45 G Frame Open Circuit Axial Piston Pumps
Service Manual
Introduction
This manual includes information for the installation, maintenance, and minor repair of
the Series 45 frame G open circuit axial piston pumps.The manual includes a description
of the units and their individual components, troubleshooting information, and minor
repair procedures. Performing installation, maintenance, and minor repair of Series 45 G
Frame axial piston pumps according to the procedures in this manual will not affect your
warranty.
Performing minor repairs requires the unit to be removed from the vehicle/machine.
Thoroughly clean the unit before beginning maintenance, or repair activities. Since dirt
and contamination are the greatest enemies of any type of hydraulic equipment, follow
cleanliness requirements strictly.This is especially important when changing the system
filter and when removing hoses or plumbing.
A worldwide network of Sauer-Danfoss authorized service Centers (ASCs) is available
for major repairs. Major repairs require the removal of the unit's endcap, which voids
the warranty unless done by an ASC. Sauer-Danfoss ASCs are trained by the factory and
certified on a regular basis.You can locate your nearest ASC using the distributor locator
at www.sauer-danfoss.com
