Figure 4-45A. Timing the Winch Motor
(1)
The first step in timing is to locate the largest open pocket in the geroler; mark the location on the outside
edge of the geroler. Aline case drain hole and pressure relief hole in geroler with similar holes in bearing
housing. Install geroler on bearing housing. (Retain rollers in outer geroler ring if they are loose.) Install
valve drive in geroler. Aline case drain hole valve plate with case drain hole in geroler. Install valve plate
(seal side toward geroler) on geroler.
(2)
The second step is to locate the slot opening in the valve plate which is in line with the largest open pocket
of the geroler.
(3)
Finally, locate any one of side openings of the valve that goes through to the face of the valve. Line up
this side opening with open slot of valve plate that is in line with largest open pocket of geroler. Rotate
valve clockwise (one-half spline tooth) to engage spline teeth of valve drive. This provides the rotation
shown when pressurized as shown in Detail B.
g.
Apply clean grease on three balance ring springs (12, Figure 4-45) and install in three holes located inside
boreface of valve housing (3). Apply petroleum jelly to small seal (11) and install in case drain groove of valve
housing. Apply petroleum jelly to o-ring (10) and install in outside groove of valve housing.
h.
Apply petroleum jelly to inner and outer face seals (15, 16). Lay the balance ring (13) with the seal surfaces up
and install the inner seal with the outside diameter facing down and install outer seal with the outside diameter
facing up.
