So the early 33 clutches did not have a cork lining like the 45`s - Just metal to metal cone surfaces?
It makes no engineering sense - to me - that this cone clutch worked without some clutch lining
Yes as we know the cone clutch is one of the cheapest clutches to produce so why not make it cheaper again and have metal to metal contact.
The Qualcast Royal Blade from memory has no lining on the cone clutch just metal to metal contact ,I've looked at a Qualcast Royal Blade cone clutch before but haven't seen the SB 33 apart from this Forum.
I can think of a few examples where this type of cone clutch does not have a replaceable clutch lining eg.synchro rings used for automotive gearboxes ,LSD differentials used in many vehicles but these two examples are in a wet environment.
The cone LS Differentials are metal to metal contact.
