Assembling the Wheels
1. Position the tire onto one wheel half, aligning the

assembly, aligning the wheel and the tire lugs and the
mounting holes (Figure 30).
4. Using 2 fully threaded screws or bolts (1/4-20 x 1.50

halves together. Mount the screws or bolts in the
opposing holes (Figure 30).
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 30).
