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).
