I think Leon is talking about Silicon Nitride. Have a look at this: http://en.wikipedia.org/wiki/Silicon_nitride I'll try it if there is a UK source? REgards, Mark

Sorry to say leon that it isnt the answer. I used the ceramic ball but to zero effect. Ed

Ed I have worked on countless numbers of these clutches, some drive me absolutely nuts others I have fitted and can't believe how well they work but as with all of them it is only a matter of time before they go to pot. I get them all working but it is a never ending battle of try this try that but with the Newby clutches I have fitted, adjust them and forget, smooth operation from the get go. Fit a new Indian clutch and you can expect all sorts of problems, but I eventually get them working and have my fingers crossed. The clutch on my Inter slips under acceleration but apart from that it is fine and I can even select neutral when stationary, so because of this I'm too scared to touch it, leave well enough alone till I really have to fix it

Norm: I bought my 1/4" ceramic ball bearing for just under $5 from this engineering / hobby parts store on Old Cleveland Rd Capalaba Brisbane.
There is a menu on the left, `ceramic bearings`. They stock everything you have ever wanted but were afraid to ask for.

Thanks everyone for all the suggestions. Connie now has a silky smooth, lightweight clutch which neither drags nor slips. Did several things: 1. Cut the pushrod into 3 pieces and reassembled with 1/4 steel balls (I reckoned point contact wouldn't allow much heat transfer) and loads of grease. 2. Practiced my forgotten metallurgy skills from Apprentice School hardening the rod ends too! 3. Shaved off a few bits of Cush drive rubber which were preventing the 'ring' sitting square (before installing the post sleeves). 4. Shimmed one of the posts to allow the pressure/spring retainer plate to sit square. 5. Flattened a slight bend in the final steel plate. My take-away lesson from this is that it IS possible to get a good clutch with minimal cost outlay, by taking time to 'blueprint' all components. Thanks again All! Stephen

Good to hear Stephen and they can all be set up to work well, it is keeping them that way that is the issue, getting caught up in heavy traffic will often cause problems, but good luck I hope it continues to work well
