Servicing the Wheels

Removing the Wheels

1.Stop the engine and wait for all moving parts to stop.

2.Disconnect the wire from the spark plug (Fig. 6).

3.Remove the bolt, the wheel spacer, and the locknut mounting the wheel to the pivot arm (Fig. 29).

4.Separate the wheel halves from the tire by removing four bolts and four locknuts (Fig. 29).

Note: If you remove the bearings from the bearing/hub assembly, remove them by pressing on the bearing spacer (Fig. 29).

Assembling the Wheels

1.Position the tire onto one wheel half, aligning the lugs on each (Fig. 29).

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 (Fig. 29).

3.Place the other wheel half onto the bearing/hub assembly, aligning the wheel and the tire lugs and the mounting holes (Fig. 29).

4.Using two 1/4±20 x 1.50 in. (6 x 38 mm) fully threaded bolts and non-locking nuts, loosely secure the wheel halves together. Mount the bolts in the opposing holes (Fig. 29).

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 (Fig. 29).
