1. Use a hoist to put the track roller frame assembly in position on support. (1). 2. Install cap (2) without shims. Tighten the rear bolt to a torque of 1200 100 lb.ft. (1627.0 135.6 N m). On the left side of the machine, tighten the front bolt first.3. Tighten the other bolt to a torque of 1200 100 lb.ft. (1627.0 135.6 N m). Measure the clearance between cap (2) and the track roller frame at the bolt. Remove the bolt on the clearance side of the cap and install shims to equal the gap plus .005 to .008 in. (0.13 to 0.20 mm). Install the bolt which was removed. Tighten it to a torque of 1200 100 lb.ft. (1627.0 135.6 N m). 4. Use a hoist to put the front of the roller frame in position. 5. Install bolts (3) but do not tighten.6. Install shims (4) between the track roller frame and front support.
