opposite alignment studs. Remove alignment studs and install
remaining bolts (or studs and 4 nuts for earlier models). Torque bolts

install case drain plug with seal, parts shown in Figure 22 (plug torque

A different bearing housing is used on wheel
motors (see Figure 24). Other than this, the
parts are the same as the standard motor and
the same disassembly and reassembly
procedures apply.
Bearingless Motors
This motor is the same as the standard without the shaft/bearing
assembly, bearing housing and retainer. The mounting flange replaces
the bearing housing (see Figure 25). Follow same disassembly and
reassembly procedures as rear section of standard motor.
Important: Loctite ® information for bearingless motor on page 10.

drain hole in valve plate. Install valve housing against valve plate (see

body parts of motor for unseated seals.
