[QUOTE="john998, post: 11965, member: 289"] [b]Clutch seal[/b] Hello Richard, To attempt to answer your question, having looked at all the usual sources I looked in Paul Richardson excellent book. The difference between G3AS and G3/1AS appears to be that the later one has a small plain spigot between the thread and the spline. This is I think for the 'O'ring to sit on. The clutch carrier C13 has a recess for the C18/1 bonded seal, the later C13/1 has no recess. The earlier nut C20 has a flat face to match the C18/1 seal. the C20/1 later nut has a counter bore for the 'O'ring.. You need to have all the earlier or all the later according to Know thy beast (another excellent and essential book), except you can adapt the G3 shaft by making a small sleeve Page 118. I am not sure of the C18/1 thickness perhaps someone else will come up with that info. John. [/QUOTE]
