Well, I found the undersized roller part number for the mainshaft side cover race rollers [ no change to part number ] but I've yet to find the part numbers for the undersized rollers on the clutch gear side. What I have noticed, is how the parts and service manuals differ so much. All my later parts and service books note only standard to oversize rollers used. My early books list over and undersized rollers but one of my early books, lists only the side cover side with undersized roller availability.
Taken from 99486-73 Service manual, page 4D-25
Notice how instruction is given to ream clutch gear bushing if replaced [ mainshaft rides in this bushing ] but no instruction is given for line lapping, nor line honing, the clutch gear roller bearing case race, if replaced. Why does this service manual not instruct the mechanic to align the clutch gear bearing race to the side cover bearing race ? Assembly and fitting instructions, directly follow the paragraph I posted from this service manual. This service manual ,would have been the last service manual, a dealership mechanic would have used, during the production life of the 45 model. In the engine chapter, instruction is provided for detail engine case bearing race line lapping, yet no instruction is provided for the transmission case to do the same. Pa
