The above machines will have one of two tow point roller designs. Some machines have a 44 mm (1.75 in) O.D. X 40 mm (1.56 in). 133-9182 Roller Bushing rolling on a 25 mm (1.00 in). O.D. X 43 mm (1.68 in). 133-9183 Bushing. Other machines have a 102-1679 Cam Follower Bearing with 031-5183 Spacers. The roller and bushing design may become pitted or galled between the roller and bushing. The pitting and galling may cause the tow point to ratchet or jerk. This may cause mat irregularities and ridability concerns. Solution:
Remove the four 89 mm (3.5 in) X 13 mm (.5 in) - 13 UNC bolts from the four rollers on each side of the machine. Inspect the rollers and bushings for pitting or galling. Replace each damaged roller and bushing with 102-1679 Bearing and two 031-5183 Spacers.Please share this information with your TEPS Dealers. COPYRIGHT 1998 CATERPILLAR ALL RIGHTS RESERVED
