[Walt Dupont--Me.]

The rear seal in your picture looks like the BEST brand, that is the best seal you can get. instructuons are usually with this seal on how to install it. Smear a thin coat of RTV on the end of the seal over the aluminun seal retainer before installing the rear main cap. The one piece front seal works good, just make sure the seal wear sleeve on the crank is not worn a belley in it where the seal rides. Walt
