the wheel 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).
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 30).
7. Install the wheel to the pivot arm with the
bolts, a spacer, and a locknut. Ensure that the
