    Is this rear crank seal correct on my 1200?

    Finally getting in to the 1200. I noticed the rear seal looked backwards and was getting ready to pull and replace it the right way, but I noticed it doesn't look like the seal on my 1050's. It looks bigger and like it fits in the notches where the snap ring is supposed to go.

    On the 1050's I've done, you could pull the seal out without splitting the cases if you wanted to. There's no way this one is coming out with out splitting them....and I don't want to do that unless I have to!

    Check out the pics. The third one shows a regular seal and how it would just slide right in to the opening without splitting the cases. I also thought the spring was supposed to go "in" on a seal like this.

    What say the Hulk? Is this just a different style seal that doesn't need the circlips?

    The retainer clip goes in first, with the ears staright up.
    Grease and install seal with spring and lip FACING IN towards the crankshaft.
    Apply grease and install o ring and seal collar.
    Install seal retaining clip with ears facing upward.

    So I take it that means it's wrong and I'm splitting my cases!


    What's the difference between this seal and the brown ones I've used on the 1050's?

    I just noticed yours in a 2001 and that might have 2 seals.
    If it does, one seal with spring faces inward and the other outward as in your top photo.

    Let me grab a manual.

    I don't know the history of the motor...so I can't say for sure it's an '01. But given the original assembler, I could believe that it was put together incorrectly.

    Well in 2000 they show the single seal and 2001 it's 2 seals, in which case yours would be correct.

    Pull the center seal collar and see if you have one or two seals.
    Give it a pull/twisting action and it should come out fairly easy.

    Brilliant! Didn't even think of that!

    Two seals. Good to go!

    Thanks!



    I can't believe I've put this thing off so long. Looking around the shop, I'm pretty sure I have 99% of what I need to complete it.

    Cool, glad you don't have to go through a tear down.
    Did you perform a leak down on the block, just to make sure she has no leaks?

    Not yet. I need to though. Looks like it was sealed up pretty well. Gotta build a tester...
