Assembly

HANDLE
NUT
ROLLER
1. Place one spacer over the bolt.
2. Lightly grease the split tube spacer.
3. Place the bolt and spacers through the roller. Insert
the bolt through the handle.
4. Install the locknut onto the bolt and tighten. Adjust
the nut so the bolt no longer turns freely. A minimum
of two full bolt threads must be visibly extended
through the nut.
CASTER WHEEL
1. Grease the outside of the wheel spacer using stan-
dard automotive grease and insert it into the wheel.
2. Place the wheel and spacer into the yoke and align
the holes in the wheel with the holes in the yoke.
3. Insert the bolt through both sides of the yoke. Make
sure the threads of the bolt are to the outside of the
yoke when the yoke hangs down in the trailering
position.
4. Install the locknut and tighten until the yoke is just
tight enough against the metal spacer to keep the
spacer from rotating. Do not overtighten, this can
cause the spacer to deform and bind the wheel. The
wheel must spin freely.

NOTE: This motor may also be used on some machines
manufactured
0030001050.

Removal

1. Remove the two bolts securing the motor to the
swing drive.
2. Lift the motor up to gain access to the hydraulic lines
and tag and disconnect the lines running to the
motor. Cap or plug all openings.

Disassembly

NOTE: Before disassembling the motor, it is highly recom-
mended that paint or a marker be used to make a V
shaped set of lines from the end cover to the hous-
ing to aid in proper assembly. It is also important that
the steps involving timing be followed carefully to
insure proper motor operation.
1. Remove all shaft related components from the shaft
(i.e. keys, wire rings, nuts). To aid in assembly of the
motor, make a V shaped set of lines from the end
cover to the housing using either paint or a marker.
2. With the shaft facing down, secure the motor in a
vise by clamping onto the housing.
3. Loosen and remove the bolts holding the motor
assembly together.
4. Remove the end cover.
5. Remove the body seal and discard the seal.
