Sorry is this has been covered before, but the 4 spring clutch on my 66 Hornet is knackered beyond all hope.

Assuming I could find a *complete* later type 3 spring, could I use that for a direct replacement of the earlier 4 spring type?

I had the same thing going on with my 65 Rocket. Ed at EV Engineering put together a complete 3 spring clutch for me for a reasonable price and I added a new SRM alloy pressure plate. A world of difference, much lighter lever and I only get a false neutral if I'm being sloppy.

It works but you must replace the chainwheel along with the rest of the clutch. I'm assuming that's what JW means by "complete clutch".

If the 4 spring centre is still good you can modify it to work with a 3 spring chain wheel, map make a nice 4 spring alloy pressure plate as well as the three. I use this set up with extra plates and 4 heavy springs to cope with the power of my 883 motor. So the 4 spring versions can be used to good effect when you need the extra clamping force.

I replaced everything. I ran around in circles with it for sometime,replacing the most worn out bits, but being 50 yrs. old it all had too much wear to really work as it should. A worn part has a tendency to bitch up a new part it comes in contact with. My hub center had too much wear also or I probably would have done something like Mark did.

'map make a nice 4 spring alloy pressure plate as well as the three.' as do SRM, a worthwhile investment.

It seems that these days, bet kits are similar in price to replacing complete clutches, maybe worth looking at.
Some blokes used Trident clutches on 'em too.
I used a 4 spring when racing, better than the 3 spring by a mile. Not just spring weight but method of construction/operation.
You still can't beat Surflex plates either.
