Have you given any thought to the condition of the shaft on the drive gear itself? I had one that picked up a bit of moisture at some point and as a bit of rust formed near the outside, when I disturbed it leaking followed. Would advise a bit of wet/dry paper on it to smooth it out prior to re-assembly.

Difficult to tell from the picture you posted, but it looks like a gap around the edge of the circumference on the end of where the seal should fit. Are you sure that is Solid Metal? And not some washer put there by a PO? (PO= Previous Owner). Put a small punch in from the engine end of the assy, and drive the seal and what looks like a washer out. Thats what it looks like anyway. If not consider getting another housing assy.

I just checked to make sure I'm not crazy, it's a rubber seal for sure.

I didn't want to pry it out because I trying to keep the engine closed for cleaning , but it's defiantly rubber and deep too.

Can you fish around underneath the metal face or is it a straight drilled hole ?

yea sorry about quality but my missus and cameras.. well lets not go there..
I said the same to her so to prove the point she sent a video of her tapping it with a screwdriver and it's definitely metal,
when i get home i'll try prising it out as it could be a PO fitted washer !!
but you can see why i was getting confused! :-)

yep there was a PO washer installed covering the seal up. it took some prising but it's off
the seal underneath is completely knackered and rock hard, now comes the fun bit of getting that out!
I notice you can buy new kits on ebay for around 30-40 bucks i might have to order one of those as mine's a little bit chewed up.

Cool, mystery solved B)

Your housing doesn't look that bad from here :)

If you get a proper O ring for the shaft and are able to pull that seal out safely I think you'll be alright.

You might try smearing a little Permatex black where the seal meets the wall of the housing and press it in.

Then again it would be a drag to have to mess with it any more so it's your call.


Good luck

old seal came out easily when i heated up the housing
fitted new and went for a test ride and not leaking yet :-)

buy the way the old girl (the bike not wife) won the peoples choice at a local classic bike show last week !!
Off to another show tomo but it's much larger and i feel there will be a fair amount of competition so just viewing not entering.
Thanks for all the advice guys (especially the nail polish!!)
