<-=- Club Bevel Heaven -=->

I am looking for a complete dry clutch unit for my bosch engine track bike.
Please PM me if you can assist

Very nice....$2800...ouch!

Unless you have 100+ bhp you can use this one.
more money ver for the restof it...

Thanks for the responses so far, the Smith japanese link looks promising, I will do further review, yes that seems expensive, but have you priced a Mario Sassi unit? A bit more than that in OZ $$.
As for the Nova straight cuts, I already have them fitted in the engine, I did that thinking things would be fine, well, the answer is no to that.
I dont know exactly how much HP my engine is putting out but its enough and a dry clutch is what I have to find.
Only issue with Smiths unit I see is that you would have to take the cover off is you wanted to inspect plates and if heaven forbid you decked it, its still a one piece cover.
So no one has a decent 2nd hand unit no longer used??

Does anyone know if you can fit a modern Ducaticlutch to the smith or the novakit?

Thanks

JUst a suggestion,and I may be wrong:A dry clutch is great of course,but,the cost and hassle are big issues. How about:forgo the dry clutch.Go with stiffer springs,or washers (under!) the springs,and,go to a lighter oil,in case you are using the bad old 50Wt we used to use. Also of course,the clutch may slip/drag erraticallly if all the splines are not in great shape.The recipe above fixed clutch slip problems for me with a pretty strong 750.

WARNING: possible oil discussion.

Ray - what was the bad old 50W that you used to use and what is the spec of the lighter oil that you now favour?

And is that a round case 750 that you referred to?

Thanks
Steve

Yes,a round case. We used just that,50wt. Probably Castrol,but it doesn't really matter. Now it seems to be the consensus that cavitation and fill-in (fall-in) at the pump,crank flywheel oil "drag" etc were problems not justified by any questionable lubricity advantage. I don't know.I do know that getting that kind of oil out of the plates of a wet clutch can be an issue. For example,we used to fix slipping Norton clutches by just glass beading the bronze discs and going to a very light oil in the primary,and not too much of it.As for shimming the springs,I had a heck of a time finding suitable washers.but our A-number-one parts man got them somewhere.

What thickness washers did you use??

Cheers

Thsat was a long time ago! What we wound up with 450 springs,and the washers underneath the washer cup. The dimensions were tricky in terms of outside diameter,to get them to fit in. Thickness was about 2mm or more,but I never measured them.It was a fairly stiff clutch pull.

Ray ..I've got a V2 NOS Dry Clutch ...I think it could be used for a Bosch bevel. 2100.00 plus shipping regards Bill

I fouled up. That recipe I posted used springs from a 450. Cobwebs in the mind,after 30+ years...
