Ramsey Winch RPH-15000 - Manual (Page 10)

Set winch on gear housing end with motor end bearing (item #3) up. Insert (6) springs (item #42) into pockets of motor end
bearing (item #3), as shown, leaving top and bottom pockets empty. Install coupling (item #25) over splined end of shaft
(item #8). Put (4) brake pins (item #9) into (4) holes in motor end bearing. Install well-oiled o-ring (items #33 & #34) and
backup rings (items #35 & #36) into grooves in O.D. of piston (item #4). Place o-rings into portions of grooves nearest to
center of piston in both cases. See SECTION A-A below.
Piston (item #4), brake disc (item #27) and separator plates
(item #39) must be clean and free of grease and oil.
Place piston over pins (item #9) and on top of springs (item
#42). Place separator plates (item #39) and brake disc alter-
nately on top of piston, as shown below. Press larger diame-
ter end of (4) springs (item #43) into pockets in brake hous-
ing (item #7). Place gasket (item #28) on top of end bearing
(item #3). Place brake housing over brake parts with fitting
ports downward toward mounting feet. Align mounting holes
and force brake housing down onto end bearing (item #3).
Apply 271 Loc-tite to 6 capscrews (item #17) and finger
tighten until flush with surface of brake housing. Torque cap-
screws (2 turns each) in a criss-cross pattern until a torque of
30 ft-lbs., per capscrew, is achieved.
Place gasket (item #29) into position on mounting surface of motor (item #31). Slide motor shaft into coupling and attach
motor to brake housing (item #7). Use (2) capscrews (item #20) with lockwashers (item #24) and torque to 87 ft. lbs. (118
Nm) each. Securely connect tube (item #44) to elbows (item #26) in valve (item #45) and in bottom of brake housing (item
#7).
Apply at least 550 PSI hydraulic system pressure to release brake and verify that brake releases, by observing that the winch
drum rotates.
