Does anyone know why the snowblower motor and or shaft/ stator seems to elongate creating a space between the motor mount and the spinning rotor? The rotor can be pushed back down but it works back up and the gap can get quite large.
Thinking ahead 
Was there another snow blower near by? 
Lmao 
Good one! Made me laugh out loud. 
Hi there, if you have concerns about this, please feel free to submit a support ticket along with pictures or videos showing the issue. Our support team will help further investigate it for you.
I experienced this issue with my first Yarbo snowblower. I am trying to problem solve a DIY solution to prevent it happening again.
It seems to me to be and internal second stage motor issue. An internal part is damaged by heat created by hard use allowing excessive movement.
I am wondering if an external shaft bearing, between the motor and the pulley, might prevent movement.
Another suggestion is a means of improving the motor’s heat tolerance or heat dissipation, lengthening its lifespan.
An actual physical “stop”, above the motor, might stop the movement.
