Can the belt tension be adjusted?
1 answer-
StrongwayExpert12· 2 years ago
The belt will stretch after using it a while; however, the spring below the motor will help the belt stay taut according to the natural stretch, so it does not require manual adjustments unless the spring is damaged.

Can this motor be replaced with an off-the-shelf motor if this fan goes out of production and is no longer available
1 answer-
StrongwayExpert12· 4 years ago
The motor can be replaced, but it needs to be done at a Northern Tool service center because it requires welding. The motor needs to be welded to the frame structure.
