1925-1931 Transmission Main Drive Bearing Retainer (with elastomer seal).

This aluminum part remedies the problem of warp in the original pot-metal retainer and the elastomer seal prevents grease from leaking out of the front of the transmission. Comes with gasket. Only fits passenger and 1/2 ton truck with 3 speed transmission.

Caution: Some transmission main drive shafts have a bleed hole forward of the main drive bearing. This hole appears to be somewhat random in its location. If the hole is present and located such that any part of it is within the range of 7/16" to 1/2" from the face of the main drive bearing, it is not recommended to use this retainer with seal.

The expansion plug and cotter pins required for assembly are also included. All parts are identical to the originals but with sintered bronze bushings for long life.
