Title: oil leaks
Post by: Ethelred on 21.06. 2013 19:17

Are there any things made of modern materials to replace the bits of cork and felt which allegedly keep the oil on the inside?
I've got to replace the cork washer on the dynamo, the felt thing behind the clutch, and who knows what else and I'd rather only do it once.
Or do we take the view that 'they all mark their spot', 'oil's cheap', and just live with it?

 There was a post  http://www.a7a10.net/forum/index.php?topic=5117.msg35077#msg35077  on an oil seal for the sliding plate but still used the felt behind. If the bush in the inner timing cover is good, there shouldn't be any/much oil in the dynamo compartment for the cork to seal in.
The only spot that isn't sealed is where thw mainshaft exits the countershaft, but if the bushes are OK in the countershaft it shouldn't be a problem. I have a special nut for the countershaft sprocket with a built in seal.
