crankshaft rear oil seal, original part, 364692R91, new, seal spec 3.885" o.d., made in Mexico, replaces 251363R11 and 251363R21 retainer with seal assemblies.

Note: This seal will not be a tight fit in either of the original used crankshaft rear oil seal retainer assemblies.  Unfortunately, we are not aware of a better fitting seal on the market from any source, for either of the original retainers. 

This leaves two options:
1. Stake, pin, epoxy, and/or silicone this seal in your existing used retainer
2. Purchase a new rear seal retainer, our stock number EN377

For use with:
McCormick Farmall Cub 1947 - 1964
