Any advice on fitting valve stem seals on a yb? Had a quick go earlier and found the seal very hard to fit over the guide. How have u done them?

 

I did mine using a small socket , one that sits over the top part and down onto the middle of it, and then gently tap in on, make sure you put a bit of oil on the guide and the seal first.

 

Just use a bit of lube !

 

Thanks guys will have another go tomorrow with fresh head! I did use some lube maybe I need better lube??

 

May sound obvious, but make sure you're fitting them to the right side. i'm fairly sure you'd know if you weren't though.

 

STOOOOOOOP!!!!
fair play for having a go but be careful. You should really use a valve sleeve to stop scuffing the inside of the stem seal as you drive it down. The ridges that house the collets can cause this and make the whole job a waste of time and money.
Oh and yes a socket is the best way to do this. Allowing the top of the valve to poke out of the socket hole as you push down.
