PREVENTATIVE MAINTENANCE

Check Swing Gear/Pinion Backlash

1. Remove the cover to expose the swing pinion and ring
gear.
Rotating gears can cause injury. Keep hand clear of rotating
pinion and gear while the mast is rotating. Start the engine
and rotate the mast until the high point on the swing gear is in
alignment with the pinion. The high point is punch-marked on
the mast plate (Figure 5-53).
2. Using a feeler gauge, check the backlash between the
gear and pinion. There should be no clearance between
the swing gear tooth and the pinion tooth. If there is any
clearance, adjust the backlash. See Section 9,
Structurals.
