3.11 DRIVE MOTOR (SN 0300183331 THROUGH
0300189341)
Description
The drive motors are low to medium power, two-position axial
piston motors incorporating an integral servo piston. They are
designed for operation in both open and closed circuit appli-
cations. The standard control is a direct acting single line
hydraulic control. The integral servo piston controls motor dis-
placement.
The motors are spring biased to maximum displacement and
hydraulically shifted to minimum displacement. Minimum and
maximum displacement can be set with fixed internal stops.
The large diameter servo piston allows smooth acceleration
and deceleration with relatively large circuit orificing.
Disassembly
NOTE:
Removal of the end cap voids warranty.
During assembly, coat all moving parts with a film of clean
hydraulic oil. This assures that these parts will be lubricated
during start-up.
Replace all o-rings and gaskets.
It is recommended that all o-rings be replaced. Lightly
lubricate all o-rings with clean petroleum jelly prior to
assembly.
