BRAKE SECTION ASSEMBLY
1.
Re-assemble the driver/clutch assembly (14, 17,
18, 19, 52) making sure the clutch is installed
properly and checking to make sure the cam
clutch is free turning in the pay in direction.
2.
Measure the distance from the face of the brake
housing to the end of the shaft as shown
(Figure 3).
3.
If needed, add shims (111, 112) inside the
input driver (54) next to the end of the input
shaft (39-2) to achieve dimension noted.
If measurement is
between 1.547 &
1.622, use Item 111 (max of 3 shims). If
measurement is between 1.622 & 1.727, use
Item 112 (max of 2 shims).
4.
Install the bearing housing assembly that contains parts 15, 16, and 22 into the brake housing.
5.
Install the driver/clutch assembly onto the input shaft (39-2).
6.
Install the stator plates (12) and friction discs (13) starting with a stator plate and alternating
between friction discs and stator plates until seven stator plates and six friction discs are used.
Dip friction discs in lightweight Non-EP oil before installation.
7.
Install the piston (5) into the brake housing (20) and gently tap it down until it is seated making
sure not to damage the o-rings (8, 10) or back-up rings (9, 11).
8.
Install the springs (7) into the spring pockets. If working in a horizontal position, coat the
bottom of each spring with chassis lube to keep it in position.
9.
Install the cover (2) onto the brake housing (20) using four capscrews (3) being careful not to
damage the o-ring (6). Draw the cover down evenly, alternating between opposite hex bolts.
Make sure that the cover is aligned properly with the brake housing in order to orient the motor
as it should be.
