The center of sprocket (16) is to be in the center of rear track roller (12). Clearance (14) is to be the same as clearance (15). Add or remove shims (3) to make clearance (14) and (15) the same or within .06 in. (1.5 mm) of center.
The thickness of one shim is .029 in. (0.74 mm). Use the least number of shims possible and not more than seven shims on each side of the machine.

6. Remove cap (6), lock (5), nut (4), retainer assembly (2) and shims (3).
7. Install shims (3) to move track roller frame (13) out to increase clearance (14) and (18) and decrease clearance (15) and (17). Remove shims (3) to move track roller frame in to decrease clearance (14) and (18) and increase clearance (15) and (17).
8. Lubricate bearing (1) through grease fitting in support. Make sure grease goes all the way around between bearing (1) and holder (9).
9. Put 1P808 General Purpose Lubricant inside of retainer assembly (2) and install retainer assembly.
