chainwheel thrust washer

[stev60]

Because of excessive noise from clutch have found that the thrust wosher and collets were missing, managed to get collets but not the thrust, can some one give me a description of one, is it possible to make one or something that could replace it

Model 51 A7 six spring clutch it looks to me, like its just a spacer, but must apply some sort of pressure

Hi Stev
The thrust washer has a recess on the inner side that retain the collets in place
Be careful a smaller one is fitted to C11G and C12 models

 They originally came in three different thicknesses, but not sure where that measurement applies;
I think you won't have much choice of thickness.
I have a profile drawing of one somewhere

 67-3276       (0.122"- 0.126")
 67-3277       (0.138"- 0.140")
 67-3278       (0.148"- 0.150")

The Collets/ 'Thrust washer abutment Ring' /halves is # 67-3251.

They could be made from the right material if you got stuck.

Looking a bit dumb here, I do have the thrust wosher, just the collets missing, I thought there may have been another part as there seems to be a a large amount of float on the sprocket, hopefully this will be taken up when collets are in place

.........hopefully this will be taken up when collets are in place

 Fair chance

spot on dutch, its working perfectly  no noise, no clunking gear change,
the float on the chain wheel is as it should be, when I put the new clutch plates in, I didnt go past the that thrust wosher,  but someone before me had , and left a few bits out, what im learning is there has always been someone doing something before you, its a good learning curve

G'day Steve.
Your lucky to escape without major damage. Without the collets the whole unit can float around like a "richard" in a shirt sleeve  .
 All previous owners should be hung drawn and quartered, then shot. I rebuild anything that looks like it had been touched by one.
Cheers

Possibly I should be included in the being shot mob, I should have gone that one step further, I actually didnt realise they were there, until the noise made me look again and noticed the excessive float on the chainwheel Il claim ignorance as a defence
