It's going to be a lot easier to get a seal that rides on a slightly different spot on the sealing surface. Get ahold of a bearing supply house. Give them your existing seal number and they'll be able to find you a seal with the same dimensions but with the seal lip offset a fraction one way or the other. I did this for the front main on my 283, works great.

If you can't fix it with a hammer, it's an electrical problem
