Pulling the shift shaft seal

[JPaganel]

I need to get that replaced soon. I'm pretty sure I can get by with my normal bag of tricks, but is there something specific that makes it easier? That seal is pretty tiny, not that easy to hook onto.

Who uses what?

I think when I replaced it, I just used a flathead screwdriver, and levered it out. Super simple!

That's exactly how the pro's do it. Yet another example of having the job done by the time you've even found the special tool.

This has been my seal remover for 50 years, sharpened to easily penetrate the steel outer, solid shaft so it's not springy.










There's a bit of knack to it but not much of one.

I personally remove the shift shaft when I replace the shift shaft seal. Once the shaft is out of the way a screwdriver can be inserted and easily pop it out.

I remove the shaft for one single reason, the bur/edge on the shift shaft that is left by the e-clip that is holding it in the case. The edge left behind easily cuts the seal lip and you can still have a leak even after replacement. I have tried to use a file to knock down the edge, but in the bike and so close to the case, you cannot get it all.

If you do replace the seal with the shaft in, please use a significant amount of care. Attached are some photos of a shift shift I just replaced after the owner damaged the shaft by gouging the shafts seal surface.

Also you need to be very careful of the outer seal surface too. This is out of the same engine when he tried to replace the crank and transmission seals: http://www.fjowners.com/index.php?topic=18759.0

Got it replaced, it went pretty easy.

I screwed a drywall screw into the old seal and yanked it with visegrips, it came out no problem. I was careful where I put it, and did not go outside the rubber on either side. No scratches on shaft or block.

Drove it in with a tube made from a broken paint roller handle where bearing surface was a plastic ring of exactly correct size. New one popped right in place.

Couple of rides, no leaks so far.
