Mine is leaking a tad around the housing but the seal is close to being flush so I think that is the cause. [Reply]   [No Email]

I got the new seal installed and it stopped the oil leak. My cover hadn't been removed so it was a matter of popping the old seal out and seating the new one. To seat it squarely I took a hunk of high density polyethylene plastic and on my lathe turned it down to a "hockey puck". I then bored it the same dia as the crankshaft. Finally I reduced a section of the puck outside diameter slightly less than the seal and about 1/4" deep. With a hammer I was able to tap the "puck" over the seal pushing the seal in perfectly. Come to think of it, if I did need to center the cover a similar "puck" would be just the tool to do it. This post was edited by Eric Patterson at 08:26:22 11/13/12. [Reply]  [No Email]

If i"m sure you do not have one is to install the seal, leave the cover a little loose, start the engine and tap the cover a little one way and the other to center it. P.S don"t install the fan less you loose a finger or two... [Reply]  [No Email]

I like to make a spacer piece so as I am sure the seal is sitting squarely in the housing. Sam [Reply]  [No Email]
