Ramsey Winch RPH 42,2 - Manual (Page 11)

Set winch on gear housing end with motor end bearing (item #4) up. Insert (6) springs (item #42) into pockets of motor end
bearing (item #4), as shown, leaving top and bottom pockets empty. Install coupling (item #23) over splined end of shaft
(item #8). Put (4) brake pins (item #7) into (4) holes in motor end bearing. Install well-oiled o-ring (items #34 & #35) and
backup rings (items #36 & #37) into grooves in O.D. of piston (item #3). Place o-rings into portions of grooves nearest to
center of piston in both cases. See SECTION A-A below.
Piston (item #3), brake disc (item #26) and separator plates
(item #39) must be clean and free of grease and oil. Place
piston over pins (item #7) and on top of springs (item #42).
Place separator plates (item #39) and brake disc alternately
on top of piston, as shown below. Press larger diameter end
of (4) springs (item #43) into pockets in brake housing (item
#6). Place gasket (item #27) on top of end bearing (item
#4). 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 #4). Apply
271 Loc-tite to 6 capscrews (item #14) and finger tighten
until flush with surface of brake housing. Torque capscrews
(2 turns each) in a criss-cross pattern until a torque of 41 Nm
(30 ft-lb) per capscrew, is achieved.
Place gasket (item #28) into position on mounting surface of motor (item #31). Slide motor shaft into coupling and attach
motor to brake housing (item #6). Use (2) capscrews (item #15) with lockwashers (item #22) and torque to 118 Nm
(87 ft-lb) each. Securely connect tube (item #44) to elbows (item #24) in valve (item #45) and in bottom of brake housing
(item #6).
Apply at least 37,9 bar (550 PSI) hydraulic system pressure to release brake and verify that brake releases, by observing that
the winch drum rotates.
