The only conclusion I have ever been able to reach as to its purpose is to "tighten up" the oil seal. They are cheap enough and available from Drags or if I remember correctly Imay well have a spare one on the shelf.
K147-53 suggests a part originally for the KH but I can't find it in any of my KH parts books and I can't think where you would fit it on the KH. Hmmm.
Thats a relief Paul, it seems that the omission of this part by the last person to re-assemble the bike may not have been a gross error. I am trying to make sure that when I do the job, I get it as oil tight as possible. The only bad leak was from the gearbox, hence my concern in that area.

Gearbox oil leaks from the GB box are usually down the speedo cable. I have never succeeded in curing those completely, except on the Healey which has the gearbox speedo drive blanked off in favour of a front wheel speedo drive. On the other hand, my KHA is some months away from completion but has been leaking oil for about 8 months now and I have only put a small amount in the bottom of the box so far!
