Default Re: Crank seal blues

Just picked it up and installed it. 5mm thickness is just fine, and I like the quality of the SKF seal better than the no-name seal that came out. I put a little wheel bearing grease on to ease it in, and seated it with a large spark plug socket and a hammer.

The magnet is tricky to get back on, because the woodruff key wants to keep coming out of its slot and sticking to it. Also, it's easy to put the magnet in backwards; make sure the slot is offset a little bit in the clockwise direction (at least mine starts and runs good with it in that way).

Throttle response is great, and it drops right back to idle when I ask it to. I'm tempted to replace my older bike's crank seal, too.
