HARNESS AS-LIGHTING 4954111 - Caterpillar

--------------- END SUPPLEMENT ---------------Description of Change: A larger screw is now used to hold the adjusting wheel spring on the brake anchor support assembly for 120 Motor Graders. The new screw is a 10-32 size, in comparison with the former 8-32 size screw. The larger screw will hold the spring in place better, and will not break as easily as the former screw.Adaptable To: The new 8F1315 Machine Screw Assembly is used in place of the former 1H3329 Machine Screw Assembly to hold the 6D546 Adjusting Wheel Springs on later 6D541 and 6D542 Anchor Support Assemblies. Since the part numbers of the 6D541 (RH) and 6D542 (LH) Anchor Support Assemblies did not change, it will be necessary to check the hole size and use either the 8F1315 or 1H3329 Screw Assembly as necessary. With the change in screw size, the hole in the 6D546 Adjusting Wheel Spring is changed from 4.34 mm (.171") to 5.08 mm (.200"). The part number of the 6D546 Adjusting Wheel Spring did not change, but the hole in earlier springs can be cut to the larger size. Springs with the larger 5.08 mm (.200") hole can be used with either the 8F1315 or 1H3329 Machine Screw Assembly.
