All of the instructions that are stated in the following steps are based on viewing the unit from
the rearward (drive) end.
1. Remove the coupling or v-belt guard.
2. Loosen the two adjusting nuts (415A) on the forward sides of the bearing frame adjustment
plates (234F) by turning them clockwise.
3. Loosen but do not remove the adjustment plate hold-down bolts (352G) and nuts (427D)
that clamp the bearing frame adjustment plates (234F) to the pedestal (131).
Do not remove the adjustment plate hardware. Keep hardware finger tight to keep the
power frame constrained to the pedestal.
