REPAIR RAMP WINCH HYDRAULIC MOTOR (Continued).
v.
Assemble the gear housing (11) over the thrust
plate (18) on the shaft end cover (6) so that
the gear housing (11) and the shaft end cover
are concentric. Ensure that pin (17) locates in
the gear housing. Tap the gear housing (11)
into place.
NOTE
If the gears are not being replaced with new parts, reassemble the
gears with respect to the port end shaft as noted during disassembly.
w.
Take the matched small gears (9) and install
them so that they pilot into the bearings in the
shaft end cover and mate with the large gear
(7).
x.
Install the port end cover (3) onto the gear
housing (11) so that the hubs of the gears (7
and 9) pilot into the needle bearings (28); the
thrust plate (18) should also pilot into the gear
housing (11). Use a soft hammer to seat the
port end cover taking care that 'O' ring (10)
does not get pinched during the assembly.
y.
Install pipe plugs (4) in port end cover (3).
z.
Install the
five capscrews
(2) and one
capscrew (1). Tighten evenly in stages to a
torque of 200 pounds- foot. After tightening the
capscrews, ensure that the motor shaft can be
rotated by hand.
