sequence, tighten the bolts to 240 ft. lbs (326
Nm).
i. Remove the lifting equipment.
j. Route hydraulic lines through center of turntable
and frame and connect as tagged prior to
removal.
k. Using all applicable safety precautions, activate
the hydraulic system and functionally check
swing system for proper and safe operation.
Swing Bearing Torque Values.
1. Dry - 220 ft. lbs. (298 Nm).
2. Loctite - 240 ft. lbs. (326 Nm).
Checking Worm Gear End Play.
NOTE: JLG Industries requires that a annual inspection be
performed on the worm gear end play.
1. Using a dial indicator, measure end play of worm
gear, by applying side to side movement by hand to
platform.
2. If tolerance exceeds.010", reduce end play to less
than.005". Refer to Adjusting End Play.
Adjusting End Play.
1. Remove end plate.
2. Measure and record total thickness of existing shim
pack.
3. Determine thickness of shim pack required to obtain
+.001",-.005" end play.
4. Adjust shim pack thickness as required to obtain
proper end play. Reduce end play by removing
thicker shims and replacing with thinner shims,
included in kit.
5. Replace end plate and torque bolts to 90 ft. lbs. (122
Nm).
6. Recheck end play.
