I acquired a Ariens snowblower in great shape. Had a 212 predator motor. I mounted the motor but had no engine sheave pulley which is part number 02435700. So Iím stuck buying a used one for 50. But I actually want to buy 2 separate sheathes at tractor supply. It takes up less room on the shaft and I can find 2 with the right size diameter without using the step up. My issue is I really donít know anything about the sheathes. Anyone know what diameter and groove depth and all the technical stuff I need to buy 2 separate ones. Here is a pic if it helps.
