Gear selector shaft O ring leaking.
Any way of changing it with out taking the gearbox out.
Or any quality bodges.

Used 2 O rings for the time being and seemed to work but is a bodge. Need to change selector and sleeve/bush next time I'm in there.

Ok stripped out the gearbox, rear hub off etc., etc.

pulled the spline out and lo and behold... Two O rings.

cant put my hand on sticky's book at the moment but Ive read on MBs that he has in the past used 3mm O rings.
Whats the proper fix?

You can use the thicker 3mm o-ring,but if the bush or selector shaft are badly worn they should be replaced.

thanks,

Does the sleeve knock out with a drift? if I took one from another case, would it be re-usable?

found stickys book but cant find it shown

The bush has to be knocked out using a drift after the case is heated in that area.Using one thats been knocked out of another case is a bad idea because it wont necessarily be exactly the same size.Its always best to fit a new one.When you fit the bush it will need reaming to the right size.

Thanks again,

Any literature available.

"Sticky's" red workshop manual,pages 50 and 70.

Jobs a good un.

Old Bush knocked out cold , New needed some heat.
Double shim on top of the wishbone keeping everything snug.

Thanks to scooterresterations for quick dispatch.
