Snowblower (536.886191) impeller and auger turn even when handle not engaged, chewing up auger belts

I have a 8.5 HP 26-inch Craftsman 2-stage snowblower (536.886191).


When I start it, the impeller and auger are spinning, even with the lever not down.


I changed the auger drive belt and adjusted the pulley wheel position so there is no tension when not engaged, and the proper tension when engaged.


This ends up causing my belt to fail because it gets really hot from the belt guide that hits the bottom wheel when the auger lever is not engaged. Everything seems to work fine when the auger lever is despressed, but I think the source of my belt problems is occurring when the auger lever is NOT depressed.


Aren't both the impeller and auger supposed to stop turning when the auger lever is not depressed?


What part(s) might be failing to stop the auger and impeller when the lever is not engaged?

Thank you for your question.

I can understand your dilemma with the belt driving the auger when not engaged.

You are correct in that the auger drive should not be turning with out the lever engaged.

Looking at the diagram I am wondering if the return spring on the idler drive belt assemble is not pulling the pulley away from the belt far enough in the non-driving position.

If you have the parts diagram I believe it is part key# 145. It is the spring you have to overcome when activating the auger with the handle.

I would also check the idler pulley adjustment position. There should be different locations for the idler pulley to set in.

I think you are looking in the right area and I am confident you will resolve this issue.

Thank you for using Manage My Life.

Thanks - though that answer had to do with the auger NOT turning - mine is turning, and won't stop.
