Servicing the Wheels

Removing the Wheels
1. Stop the engine and wait for all moving parts

4. Separate the wheel halves from the tire by
removing 4 bolts and 4 locknuts (Figure 31).
Note: If you remove the bearings from
the bearing/hub assembly, remove them by
pressing on the bearing spacer (Figure 31).
Assembling the Wheels
1. Position the tire onto one wheel half, aligning
the lugs on each (Figure 31).
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 (Figure 31).
3. Place the other wheel half onto the bearing/hub
assembly, aligning the wheel and the tire lugs
and the mounting holes (Figure 31).
4. Using 2 fully threaded screws or bolts (1/4-20 x
1.50 inch) and non-locking nuts, loosely secure
the wheel halves together. Mount the screws
or bolts in the opposing holes (Figure 31).
5. Check the alignment of all parts and tighten
the bolts, alternating from side to side for a
uniform fit, until the wheel halves are drawn
together (Figure 31).
6. Install the 2 bolts 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 bolts and 2
locknuts (Figure 31).
7. Install the wheel to the pivot arm with the
bolts, a spacer, and a locknut. Ensure that the
spacer is positioned between the wheel hub
and the pivot arm (Figure 31).
