4.17 Servicing the Wheels:
Removing the Wheels
1. Stop the engine and wait for all moving parts to stop.
2. Disconnect the wire form the spark plug (Fig. 5 & 7).
3. Remove the bolt, the wheel spacer, and the locknut mounting the wheel to the pivot
arm (Fig. 32).
4. Separate the wheel halves from the tire by removing four bolts and four locknuts
(Fig. 32).
NOTE: If you remove the bearings from the bearing/hub assembly, remove them by
pressing on the bearing spacer (Fig. 32).
Assembling the Wheels
1. Position the tire onto one wheel half, aligning the lugs on each (Fig. 32).
2. Place the bearing/hub assembly into the center hole of the wheel half. Ensure that
the legs of the hub are positioned over the flange of the hole.
3. Place the other wheel half onto the bearing/hub assembly, aligning the wheel and
the tire slugs and the mounting holes.
4. Using two fully threaded screws or bolts (1/3-20 x 1.5 in) and non-locking nuts,
loosely secure the wheel halves together. Mount the screws or bolts in the opposing
holes.
5. Check the alignment of all parts and tighten the screws, alternating from side to side
for a uniform fit until the wheel halves are drawn together.
6. Install the 2 cap screws and 2 locknuts previously removed in the remaining holes in
the wheel halves and tighten. Remove the 2 long screws or bolts and replace them
with 2 cap screws and 2 locknuts.
7. Install the wheel to the pivot arm with the cap screws, a spacer, and a locknut. Ensure
that the spacer is positioned between the wheel hub and the pivot arm.
8. Connect the wire to the spark plug.
