Hm, well i got the 5''er at tractor supply, but the set screw in it started chewing up the shaft and without it always walks off of it. And the shaft goes from about 3/8 to 5/8, and I am assuming a combine pulley has a 1'' or larger shaft. I was considering cutting the bore out and bolting it in, but I dont want to ruin this one incase I need the super low gearing. Really wish this thing just had a regular shaft, ive been searching for one of these taperd pulleys forever.
Also I was wondering about the limited slip and brakes, is there anyway to conver this to a true 2 wheel drive? And I am putting a dual piston hydraulic brake setup on it, but the little disc is so tiny the caliper wont fit, Would a disc on the axle work with the limited slip setup or just stop one side?
