70-3789/A Outrigger Bearing
For Unit Singles (Except Cub)
Comes with six screws and sealed bearing.
The purpose of the Outrigger Bearing Plate is to support the transmission mainshaft between the clutch and the gearbox sprocket and to use the crankcase to bear the loads placed on the mainshaft by the engine and rear wheel. This will ensure longer mainshaft life and reduce the risk of a broken or bent mainshaft due to the excesses of racing, missed shifts or just plain abuse.
Note: This part can only be installed on mainshafts with less than .003" run-out.
