CD5515-2/YB5515-2 SERVICE MANUAL 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 hands 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 either punch-
marked or painted on the gear teeth (Figure 5-53).
2. Using a 0.013 mm (0.005 in) feeler gauge, check the
backlash between the gear and pinion. If there is any
other clearance, adjust the backlash. See Swing
Gearbox and Pinion, page 11-26.
