REASSEMBLY OF BRAKE HOUSING ASSEMBLY
Reassemble brake housing assembly by reversing the disassembly procedure:
1) If needle bearing, item 603, was removed from center of connecting shaft, item 600, press back into place.
2) Press a new, well-greased oil seal, item 607, into connecting shaft, item 600. If a back-up washer is included
in your seal kit, it should be installed together with and behind oil seal.
3) Install new, well-greased O-ring, item 601, onto connecting shaft.
4) Insert connecting shaft into brake housing, item 700. Slightly rotate drum to allow spline of connecting shaft
to fully engage with internal gear, item 430.
5) Install two sprag clutches, item 723, into bore of brake hub, item 720. Position sprag clutch aligners, item 722
and item 724, and support washers, item 717, on either side of brake hub. Carefully slide motor drive shaft, item
730, into brake hub assembly and secure with circlip, item 727. Verify that circlips, item 719 and item 731, are
installed on motor drive shaft.
IMPORTANT: For proper brake function, verify that the sprag clutch is installed correctly. When
viewed from the motor end, the motor drive shaft of a clockwise hoisting winch
must turn freely clockwise and lock in the counterclockwise direction.
6)
Install thrust bearing, item 617, between two thrust washers, item 615, and place on connecting shaft, item 600.
7) Install motor drive shaft assembly through thrust washer, item 615. Carefully twist motor drive shaft through
oil seal, item 607, and engage spline with primary sungear, item 440.

piston in brake housing.
10) Install 16 brake springs, item 752, into brake piston, item 750. The brake piston has 18 holes and the two empty
holes should be opposite each other.
11) Use grease to temporarily hold a new O-ring, item 801, into recess on flange of motor adaptor, item 800. Install
a new, well-greased O-ring item 707, onto motor adaptor pilot.
12)
Position motor adaptor, with brake release pressure transfer holes of motor adaptor and brake housing aligned. Tighten 12 capscrews,
item 821, and lockwashers, item 823, one turn at a time to evenly compress springs.
13) Attach base, item 550, to winch using 12 capscrews, item 551, and 12 lockwashers, item 553.
