    1275 rear seal leak

    I'm sure everyone has dealt with the oil leaking from the rear slinger type seal. I have taken my engine out 4 times in the past 30 days with no luck. I now see Moss has a rear oil conversion seal #297-655 for $300 not in the catalog but online! It states the the crank doesn't need to come out but when I look at the parts included in the kit it shows the upper cast piece with the 3 mounting holes that attach to the block which you can't change because when you back out the 3 bolts with an open end wrench the hit the back of the crank flange. My question is has anyone done this conversion? did the crank have to come out? or could  you recommend a different type of repair.

    you probably know this already but make sure your crankcase breather is attached to the air cleaner or whtever the deal is with your engine so that the crankcase has a slightly negative pressure. That accounts for many of the worst of the rear oil seal leaks.
