Getting ready to slide a 670HI into my 8050, and trying to decide how i want to install the torque limiter. I had the flywheel machined and have a new TL disc, spring, and plate from Agco. Read a few different places about stacking 2 Belleville springs and using 1/2" lockwashers on the bolts, is it a safe or "recommended" thing to do or should i just put it back as stock?

If everything is new and to specs, it really shouldn't need a double spring. Double springs won't slip, but can eventually tear out the center hub. I have occasionally taken the flywheel to be surfaced and have the shop change the recommended step dimension to about 10 to 15 thousands less.
