I'm rebuilding my D4 7Us clutches and cross shaft. Between Cat and Tractor Parts I obtained all but bearings and races for the cross shaft. I did obtain the bearing race dimensions from YouTube. Bearing ID-2.25" with matching race OD-4.875". Timken part numbers-555s and 552A respectively. Will someone that knows verify these dimensions? Cheers

Hi Roverman

The bearings are correct as i have done several d4's up, and have kept a list of crossover from cat to other manafacturing.
