Finishing the clutch

Easy job first - degrease and clean the clutch cover. Chrome plate as suspected, with a nice little ding at the front, presumable from someone's boot. Maybe we can beat that out with a handle planishing hammer and a sandbag... maybe not...
Clutch sprocket, plain and friction plates. All jolly nice; friction plates are worn but not burnt. Plate thickness is 1.6 mm/16 SWG, about 1/16". Cork protrudes anywhere between 1/32" & 1/16", so they will need relining. Since they are easily accessible from the outside, and i have 101 things to do, this job will get put aside for a dark winter night.

An additional plain plate, by the way, kindly provided by AOMCC member  & 'Cheval de Fer' magazine editor John Mitchell. Several other parts provided by John are stashed away to appear in later posts.

Next up, clutch basket, repainted by moi, cleaned original needle roller cage and thrust washer, and original pressure plate. John Budgen (John Budgen) provided a new set of rollers.
Here's the centre, which may need to be replaced. I've recut the threads, but as we've seen the splines are not good, inside or out. John Mitchell has provided another. Spring lengths vary 1.625 - 1.64", but since I'm not sure what the factory limits are we will have to see whether this is OK.

I nice set of new set screws for the basket to sprocket flange, with a tab washer - all from John Budgen.
Clutch, assembled and ready for testing. Clutch nuts all ok, spring cups ok, all assembled using my clutch screwdriver, pictured in an earlier post.
