I'll try to get the specs later today or over the weekend. I don't have a heated garage so I haven't installed my blower. So the extra pulley is not installed yet. Am just too busy this morning to take pics and get the dimensions. I do plan to install the blower this weekend if the weather is warmer and plan to take step by step pics.Does anyone on here have the dimensions of the special mule drive pulley for the 3813/4213 snow thrower? I'll need the outer as well as the bearing id. Thanks!
You are correct. The pulley is a flat pulley. According to my manual it replaces the pulley on the right in the pic below because the pulley for the deck blade on the right is a V pulley when used for mowing.I'm pretty sure the special pulley is a flat pulley without a v groove. It runs along the back of the belt.
