Hi
The 99 I have just bought had an oil soaked clutch.There doesn't seem to be any leakage from the crankshaft seal, so I'm hoping the chaincase just had too much oil. I'm fitting a clutch operating rod seal just in case.
I changed the friction plates and cleaned the rest and it works fine now, except that it rattles when the clutch is disengaged. I guess this might be a sticking plate and I will investigate. I have noticed that there is about 1/16 ins runout on the clutch basket. Is that normal? Also, my 1959 parts list shows a different configuration of clutch, with a separate inner friction plate. On my clutch, there is a plain back plate bolted to the the rear of the clutch center, which drives friction pads, integral with the clutch basket. There are four other friction plates, with corresponding plain plates and an end plate. Although the bike was first registered in 1959, do I have an earlier clutch configuration?
Any help will be much appreciated.
Thanks
Graham

Many thanks Anna. I've just received a clutch center puller, so I'll do some more investigating over the weekend.
I tried keeping ATF in the chain cases of my other bikes with mixed success. I prefer the quick squirt with chain lube before a run approach these days. It might shorten the life of the clutch basket bearing over time but that bearing doesn't work very hard and doesn't see much heat.
I'm still a little confused over the clutch configuration I have. The drum (or basket) on my clutch has an integral rear web with friction pads inserted. The clutch in my 1959 parts CD has a separate bonded rear plate. Do I have a pre 1959 clutch?
Thanks again
Graham

hello graham in 1956 norton changed the clutch plate splines round from the friction plate spline to the centre hub and plane plates too the basket As it was For the 1954/55 Domies
then after 1956 the Friction plate splines was too the basket and plane ones too the hub then in 1959 they went back too 1955 way round so that confuessed every one so your its the right one for bike ? Hope this helps Anna J Dixon

Hello again Anna
I've just received a Pitman book from ebay and there is a picture of my clutch configuration and it's a Burman (friction plates splined to basket and 18 friction pads fitted to basket). Not sure if a 1959 Domie should have a Burman clutch but that's what I've got. The picture and description in the Pitman book indicates that I should have five friction plates and six plain plates. It seems I'm one short of each. Maybe that's contributing to the clutch is rattle when the clutch is disengaged?Methinks I could be starting a voyage of discovery with this bike?!
Thanks
Graham
