Rear main thrust

[Tom Endy]

Bratton's new 2014 catalog shows a new part on page 2, called a "Brass replacement main with thrust surface". Part number 8949.

The description states that "This replaces the original style rear main oil seal #8960. This provides a superior crank thrust surface than the original babbit. Also if the babbit thrust surface has cracked off your cap this will now act as the crank thrust surface".

Has anyone had experience with this modification?
