1959 Domi 99 clutch configuration

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

Hello graham the 1959 clutch its the as four friction plates splined to the hub and four plain ones to the drum , The out of round ,And the Rattleing maybe the bearings that the drum runs on , As for oil for the clutch I use Automatic transsmition fluid, To get good seal you need to see if the two halfs of the clutch cases are level and are not bent anywhere ,And once this is done use black Lockite RVT On the inner case rubber band ,On the inside of the band only and for the out side of the rubber band Use a water proof Grease allway round the outside of the rubber band Then fit the outer case then the washer and the big nut do up the big nut untill you have two threds showing that will be OK then fit you footrests ,then top up with the ATF job done ?

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

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
