Does the shaft fail from abuse and take the bearing with it or does the bearing go to crap and take the shaft with it ? I picked up a 520 today and got it broken down to the bare case. Front pinion shaft/intermediate shaft bearing and the surface of the shaft looked great vs all the horror and carnage pictures posted by many here. Not new by any means but nowhere near nasty.
Transmission came from a 2.2 T1 Daytona. Overall decent condition (good rebuildable core) but it was evident its been given some hard usage in its past (3-4 & 5th fork pads were torn up, synchronizer teeth were slightly rounded on 3 & 4 ect)
