Crank seal replacement and reassembly question...

[rzgkane]

First off, I did look through the Bill Silver CD and well as the parts diagram so that covers that.

I am in the process of re-assembling the right side after a crank seal replacement and have a couple questions. It appears from the parts I have sitting on a rag from last week's disassembly (and I don't think I've lost any) that the order of re-assembly has the crank seal going in, and then the crankshaft starter sprocket immediately thereafter with nothing in between. Question, then, is what keeps the crankshaft starter sprocket from rubbing against the crankshaft seal? Or worse, rubbing up against the case? Nothing? Is it a non issue? Maybe the offset of the starter's sprocket keeps the crank's starter sprocket in line and off the case/seal? Curious.

Also, how much slack should be in the starter chain? Mine has so much that it actually contacts the bottom of the case. Is this typical? Should I shim the starter back a washer or two's distance? Is it even worth the effort? Pic of the area where the chain contacts the case is below:

Below are pics of the crank seal I tried to install today. Obviously it did not go in seamlessly.

A guy I talked to last week told me that he always loosens the case halves when he tries to install a crank seal (for the very reason depicted) and I thought that sounded crazy. I mean, the case halves are sealed together with Hondabond or similar and I'm thinking they would leak worse than the dang crank seal if I loosen them.

Someone here told me to take an exacto and remove the sharp edge prior to attempting to install the seal. Well, I did that, but maybe not enough? Anyone else experience this problem and can steer me to the hot tip? I took off more material and then even used emory cloth to smooth things out in anticipation of another seal arriving but I really don't want to ruin any more in what looks to be a rather simple install.

I even thought of using gorilla snot to act as a lubricant?

Bump the post above. Am I missing something?

Try using Hondabond4 around the seal before installing. It will help it slide in. Starter chain slack is a bit more than normal, but I wouldn't worry about it. I once tried to shim the starter motor back with the thinnest of washers, and it was still to much to install the chain, as well as the cover not lining up.

Thanks. How about this part of my post:

The collar keeps the sprocket off of the seal. There should be a small plate for lack of better word, that keeps the sprocket from traveling outward. it's affixed with a 6mm phillips head screw.

Ok, the little plate that keeps the sprocket from moving outward I have. Affixed by 6mm bolt. Check.
