Countershaft Bearings And Races
The countershaft bearings and races are machine lapped during manufacture to form matched sets. The bearings and races should not be interchanged.
NOTE:
The bearing races are a permanent press fit in the housings and are NOT serviceable. If a bearing race becomes damaged, it will be necessary to replace the front or rear housing as necessary. A new countershaft bearing will be supplied with each new housing for service use.
The countershaft bearings can be installed backwards if care is not exercised. The bearing roller cage is a different diameter on each side. Be sure the bearing is installed so the large diameter side of the cage is facing the countershaft gear (see Fig 1). The small diameter side goes in the bearing race.
