New Wheel Improves Bearing And Wheel Service Life {4208,4006,4051}
Usage:
615C-II (9XG) Wheel Tractors
Description of Change: The new wheel changes the dimensions and tolerances to provide a tighter bearing fit to reduce wheel bearing spinning. Also, a new design of the wheel fills in the area of the wheel between the inner and outer bearing lands to provide increased bearing support and to eliminate cracking of the bearing flange.
Adaptable To: The new 153-6458 Wheel is a direct replacement for the former 8V-6398 Wheel. The change to the 4V-5303 Final Drive, Brake and Wheel Group is effective with 615C-II (9XG1034) Wheel Tractors. The new design of the 135-6458 Wheel is effective with 615C-II (9XG1042) Wheel Tractors.
