Component damage hazard.
Repairs to the motor should only
be performed by an authorized
Sundstrand-Sauer dealer.
Component damage hazard. The
work area and surfaces where this
procedure will be performed must
be clean and free of debris that
could get into the hydraulic system
and cause severe component
damage. Dealer service is
recommended.
When removing a hose assembly
or fitting, the O-ring on the fitting
and/or hose end must be replaced
and then torqued to specification
during installation.

Bodily injury hazard. Spraying
hydraulic oil can penetrate and
burn skin. Loosen hydraulic
connections very slowly to allow
the oil pressure to dissipate
gradually. Do not allow oil to squirt
or spray.
3 Remove the drive motor mounting fasteners.
4 Slide the drive motor shaft out of the brake and
remove the drive motor from the machine.
5 Remove the brake from the drive hub.
There are two O-rings on the drive
motor and brake assembly. One is
installed between the brake and
drive hub and another between
the brake and drive motor. Be sure
that both O-rings are in place
when installing the brake and drive
motor onto the machine.
