A10 GF Gearbox Layshaft bush question
« on: 26.10. 2009 17:18 »
Greetings,

Work continues on the gbox overhaul

Does the layshaft bush on the clutch side of the gbox press out or does it have to be drawn out ??

I can't find any lip on the inside of the bush to attempt to draw it out but it appears to have a closed end that is visible from the sprocket side of the gbox?

Just wanted to check so that I don't bugger anything up !

cheers

Scotty

they press out Scotty
Did mine a while back, heated the box with a heat gun and drifted it through with a suitable socket.
Only tricky bit is getting the oil hole lined up when inserting the new bush,

Thanks Bill

Did you have to ream/bore the new bushes to suit or were they ready sized ?

cheers

The bush was ok for size with my layshaft ( lucky ) anybody putting in a new layshaft would probably need to ream though, have noticed when replacing bushes they do get a tad tighter when instaled.
Have also noticed on both my bykes, it's the end of the layshaft that sits in the bearing that gets ribbed ( for want of a better description ), haven't worked out why this should be.
