Horstman MDC

I haven't kept up on Horstman model numbers, the last Horstman clutch I ran was a wet clutch, 3 disc 4 spring model. There were no provisions for bolting weights on the levers in those days. We could go from a KT100 3 hole engine to a pipe engine just by adjusting the spring pressure. We set the 3 hole can at 8300 and the pipe engine at 10,300. It didn't take all that much adjusting of the spring height.
 
3/16 x1/2 I used 10/32 also with washers
With locking nuts .
You could use metric equivalent .
Both with bully disc's .

We've got the weight kits in stock if you need.
As for the number of weight washers that you will use, depends on the springs, spring height, class/engine and peak torque that you are trying to engage the clutch at.
