Has anyone ever replaced the crank case seal behind the primary on their m100t? If so, roughly what does this job entail? Is the seal captured like it is on a two stroke?

Mine got damaged upon the sudden failure of belt #5.

It sure looks like a retained seal in the service manual

Click to expand...

You have to pull the motor and pull the oil pan off, Remove flywheel using proper fly wheel puller, Remove bottom of Crank case Half.And then change the Crank seal.....Not a fun Job

I think I might have to machine some sort of guard to install behind the primary. That's a ton of work on a 2 stroke, sounds like much more on a 4!

That should be a warranty fixed problem. Unless you have a 2012 that might be out of warranty. I will never pull an 1100t motor again unless I absolutely have too. Done it twice now and it's I big job.

I didn't even take the sled home. It is at the dealers shop right now.

I would like to come up with some sort of a solution to partially prevent future seal failures though. Might be as simple as an o-ring slipped over the shaft, or a small aluminum ring sweated on right up near the seal.

I got the sled back yesterday. Hopefully this will keep the seal from getting torn up again.

It was held on with super glue, now it's on my bench. LOL. I think I'll try yamabond or maybe five minute epoxy before I drill and tap the case.

Can you change the seal by dropping the bottom case of the motor or do I have to pull the hole motor apart to get the seal out? If anyone know that would be sweet!
