LEG BEARING TORQUE-

inspect the tread bearing bolts on both the bottom and the side (fig. 7.96-

To torque check the bearing bolts:
1. Loosen the jam nut (fig. 7.96-1, item 2) on each bearing bolt.
2. Using an “X” pattern (fig. 7.96-2) verify current torque on each bolt
(fig. 7.96-1, item 1) is equivalent to last check from 100 hours previ-
ous. Repeat torque pattern a second time.
3. Then increase the torque two foot pounds on each bolt using the “X”
