Re: O-rings on transmission countershaft
If you have access to a machinist ,ask him about doing this
I set up the empty case on my mill,bore to holes for the cluster shaft 3mm oversize,while its still set up on the mill,turn up the new bush from steel, with the interference and about .010 under on the bore,using a bolt and nut and loctite super retaining compound, pull it into place,then bore it to the correct size.no drama,I have done 3 or four of my cases like this and they work fine.
