Auxiliary Mounting Pads and Auxiliary Pumps
Auxiliary mounting pads are available on all pumps. A sealed shipping cover is included as standard
equipment on all mounting pads.
An O-ring seals the auxiliary pump mounting flange to the pad. The drive spline is lubricated (flooded)
with oil from the main pump case.
Spline specifications and torque ratings are shown in the accompanying table.
•
All auxiliary mounting pads meet SAE J744 specifications
•
Do not exceed the maximum pump input shaft rating shown in the Shaft availability and torque
ratings table in the Shaft Options section
•
Applications subject to severe vibratory or high G loading require an additional structural support.
This is necessary to prevent leaks and possible mounting flange damage. Refer to Mounting flange
loads in the System Design Parameters section, for additional information
