6.
Using a ¼” x 4” x 8” shim (A) slide between the front midroller and guide lugs
(B). Bridge guide lugs with the shim maintaining pressure on 2 lugs minimum.
7. If the shim fits freely between the lugs and midroller on both sides of the
undercarriage the alignment is correct. It the shim binds and does not fit
between the midrollers/guide lugs track adjustment is necessary.
6.2 Track Alignment Procedure
1. Remove the retainer lock plate cap screws (b) and lock plate (c) from the inboard &
outboard sides of the track needing adjustment.
2. Loosen cap screw (d) counterclockwise 1-1.5 turns on the side of the
undercarriage you want the track to move towards.
3. Tighten the special cap screw on the opposite side to specification. (Cap screw
torque is 300 N-m (221 ft-lb). Tighten cap screw loosened in step 2 to the same
specification.
Note: A single full turn is the standard increment during
adjustment. Lessen this amount as final adjustment is approached.
4. Recheck track alignment and adjust until suitable clearance is obtained on both
sides of the guide lugs.
Note: Lock plates are reversible for double the index
increments. If needed, increase torque on the special cap screw slightly
allowing advancement to a suitable lock plate position.
