Re: New clutch item Robb Nortier.

Probably the feltring and corkbush gets more function when the long bush in the sleevegear gets worn and more oil will seep through...

Lubricating the long sleeve bush seemed to be a difficult problem, weak point in lots of designs. Hard to get oil there and too much oil will easily work out. Maybe a modern O ring seal in a groove at the end of the bush will do nowadays ???

A few weeks back there was a topic about different mainshafts....compared a few and one difference I found was in the pattern of the oil grooves/spirals over which the sleeve gear runs. Looks like BSA acknowledged this lubrication problem early.

Re: New clutch item Robb Nortier.

Interesting about the oil groove...I posted about potential main shaft differences when I spotted different part numbers but have yet to get all mine out and do some comparisons...I was hoping someone might know the answer...Personally, I wasn't aware of any potential differences until recently and I've handled scores of them over the years!!...

Lubrication design issues aside, I find the quickest way to destroy the sleeve gear bushes is not to maintain the gearbox oil at a sufficiently high level...With the standard set up and no sealed bearing, particularly if the field stand is used, the oil level can drop to critical levels in just a few hundred miles...I recommend a check every 300 miles...I'd be interested in anyone else's view on this....Of course with the sealed bearing fitted the situation is much improved and that should be considered a 'must have' modification at rebuild time...Ian

Yes, indeed. I am very sorry for that. My first attempt was not as sleek as yours. I humbly apologize my friend and thank you for this opportunity to set it straight.

No need for that, Robb.... sorry, I regret bringing it up.....

Just reading you had a gift for me, but there is no need for that either..

Cheerio and good luck with your bikes & tools. Michiel
