Hog Wild Great good chance to clean and just look it over,once I saw your picture remembered that you clamp onto the seal area to grind. So I probably padded that area with shim stock or to center may use feeler gauge thin one anyway glad you got out of that one . Earlier I rolled in a complete set of rods and mains -.002 into my 51 6400 to fix a bearing noise in it. Makes you feel pretty good when you get one fixed !!
