11. Thread the outer tube (31) into the housing (1). Continue threading the outer tube (31) into the housing (1) until
approximately 2-3 threads remain showing. Once the outer tube (31) can no longer be rotated by hand, align the
translating tube (29) clevis to the appropriate orientation.
12. Once the outer tube (31) and translating tube clevis (29) are in the correct location and the hole for the air vent (34) is
in a desirable position, spot-drill the tube. Install the two set screws (35) into the housing (1), locking the outer tube
(31) in place.
13. Install the air vent (34).
14. Assembling of the motor (10) to the housing (1)
a. Note the location of the flat on the input pinion (4) by marking the spot on the housing (1).
See Figure 6-1B on
page 45.
b. Insert the grommet (14) on the motor shaft (10) between the coupling (5) posts.
c. Apply a little grease to the O-ring (9) and install it in the housing (1).
d. Pack the brake cavity with
Mobilgrease XHP 462
grease.
e. Remove the hole plug (52) if it is in the rear end of the motor.
f. Feed the motor (10) lead wires through the hole in the housings (1), lining up the two couplings (5) located on the
motor (10) shaft and the input pinion (4).
NOTE: Alignment is critical at this point.
See Figure 6-1B on page 45.
g. Assemble the motor (10) into the housing (1). Before assembling the sealing washers (15) and socket head
screws (16), hold the motor firmly in place and, with a screwdriver, turn the motor shaft by using the screwdriver
slot in the end of the motor shaft.
WARNING

WARNING
!
HAND-TIGHTEN ONLY. Do not apply a torque-increasing device to install the
outer tube to the housing. Over-tightening the outer tube will result in damage
to the outer tube gasket.

WARNING
!
Take care to avoid damaging the motor lead wires.
NOTICE
The input pinion (4) and motor (10) shaft flats are opposite each other.
NOTICE
Before turning the motor shaft, make sure the pinion shaft has not been pushed
out. If necessary, hold the pinion shaft down while turning the motor shaft. If the
couplings are properly installed, the motor can be turned freely in both directions.
If the motor shaft will not turn, the couplings are not properly aligned and you
must correct the assembly.
