Replace Drive Motor Nordictrack Commercial 2450 Treadmill (No Unnecessary Dialogue)

[@philipjolley1015]

how do you tension the motor belt?

Thats the real question

[@benschmaus4976]

I was curious what the symptoms could be on a motor that has not quite failed but maybe is on its way out. For example on my 2450 recently if you set the speed to 4.0mph it seems the motor speed might fluctuate slightly slower for some time and then speed back up. Not always but sometimes or in one case to get a 4.0mph pace I needed to have it at 4.8mph. But maybe the incorrect voltage is going to the motor to cause this and maybe the speed sensor is the case.

Depending on the age, it might not have a speed sensor, yet the speed is still adjustable. If you're getting speed fluctuation, it's most likely an issue with the controller sending erratic voltage to the motor.

@@gitfit875 Its really subtle - like one day it was for a consistent 10 minutes then it returned back to normal speed - then once it was normal speed then slowed for the rest of the duration of use ~40min - I had to up the speed to 4.8mph to get it to go at the 4.0mph pace. Its 4 years old and only has ~950 miles on it.

Can you show us how to remove the motor brushes on this motor?

[@gitfit875]

That's a great idea! I just brought in a 2450 that's in rough shape, going to totally rebuild the thing, I'll replace the brushes on the motor while I'm at it.
