Pinion Bearing numbers???

[Money Pit]

I have an OC4 with a busted differential and I need to replace the tapered roller bearings on the pinion before I set up the ring gear.   The problem is that the numbers are worn off the bearing that the pinion gear set`s against.Dose anyone now the number for this bearing?? Any help would be greatly appreciated.

Take them with you to your bearing supplier or measure the shaft, and the bore for the cup. Also scale the height of the cup.

You will have to get them from Zimmerman Oliver Cletrac as they are not made anymore!!  The larger bearing at the gear end of the shaft has a grove for a snap ring, and it is no langer made.  Zimmerman has a similar bearing with a larger OD that is ground down from were the snap ring would be back. It requires no snap ring.  They have them specially made by someone with the equipment to do it.  I know of no other source for that bearing.  You may get very lucky and find an old Oliver dealer that may have an old original one, but that would be a long shot.  I found an original one two years ago on a internet site for $1200.   Zimmermans was less than $100!!
