Another daft question. My various books are not to clear on the positioning of the sealing washers on the ES2 chaincase.I have made up some from felt and have psoitioned them thus:Cranksheft - between inner case and crankcase cover.Footrest socket- jammed into the metal cup of the inner case.Clutch shaft - between rear of clutch and inner case. (there is no restraning device)..Does theses sound correct?Don't want to out it all back and then dismantle!
The spare parts lists are…

The spare parts lists are not very easy to read on this and I'm not sure if all inner chaincases are the same.
Russell Motors have supplied me with a sort of rubber washer with a ridge which fits in the recess at the crank (and has therefore a positive location).
Felt is certainly the material for inside the footrest tube - on some models with a steel retaining cup but filling up the cavity as you've done can't do any harm.
On the pre-war models, a thick felt washer was placed between the rear of the inner case and the nose of the sleeve gear. Wherever you place a seal on this shaft, it's going to be located between rotating and static components so it's questionable how long it will retain any efficiency.
It is of course only an 'oil-bath' so level is low and there is no pressure - it can't fill up with gearbox or engine oil, as the later twins can. Any oil above the bottom inch or so is only splash that has been carried up by the chain.
It might not be a bad idea to phone Les at Russells and ask for a full set of chaincase seals - you then have the fun of puzzling out what goes where...
