ASSEMBLY

1. 

Place the brake housing on a clean, flat surface with 

the motor end, or large end, facing up.

2. 

Install a brake spacer (Item 305) into the bottom of the 

splined bore.

3.  Lubricate the friction discs in clean oil, using the same 

oil as that intended for the winch gear cavity. Install a 

steel brake disk (306) on top of the brake plate spac- 

er.  Next,  install  a  friction  disc  (307).  Then  alternate 

steel and friction discs until the last steel disc is placed 

on top – nine steel discs and eight friction discs total.

4. 

Install the second brake plate spacer (305) on top of 

the last steel brake disc. Install the retaining ring (304) 

into the groove above the spacer. Make certain the 

retaining ring is fully seated into the groove.

5.  Turn the brake housing over and rest it on the motor 

end. Make certain the brake plates and spacers are 

resting flat on the bottom of the bore and are not hung 

up or held out of position. Insert the overrunning brake 

clutch assembly to more closely align the splines of 

the friction discs. Either support the brake clutch as-

sembly in position with a spacer on the table or re-

move it completely.

BRAKE ASSEMBLY SERVICE

6. 

Lubricate the O-rings and backup rings (309, 310, 311, 

312) with light grease or petroleum jelly. Install O-rings 

and backup rings into the piston grooves. Be sure to 

install the backup rings to the outside of the O-rings 

toward the ends of the piston. Ensure the concave 

surface of the backup rings is against the O-rings.

7. 

Install the piston (308) into the brake housing bore. Ap

-

ply light, even pressure to the piston to seat it against 

the brake plate spacer.

8. 

Insert the spring spacer (314) into piston bore. Insert 

16 brake springs (313) into the spring pockets created 

by the spacer. Two openings will remain in the spacer. 

Ensure that openings are located 180 degrees apart.

9. 

Install  the  spring  retainer  (315)  on  top  of  the  brake 

springs. Using a press, apply even pressure to the re-

tainer to force it just below the bottom face of the re-

taining ring groove and install the retaining ring (316). 

Ensure retaining ring is fully seated in the groove be-

fore removing the pressure from the retainer.

BRAKE ASSEMBLY PRESSURE TEST

Install the long tube fitting into the brake release port of 

the brake housing. Connect a hand pump with an accurate 

gauge 0–2,000 PSI (0–137.9 bar) and a shut-off valve to 

the fitting. Apply 1,000 PSI (68.9 bar) to the brake. Close 

the shut-off valve and let the unit stand for 3 to 5 minutes. 

If there is any pressure loss, the brake assembly should 

be disassembled for inspection of the sealing surfaces 

and brake piston seals, and repaired as needed. Perform 

this test after any repair to brake assembly.
