Motor belt keeps falling off - Sport & Outdoor - Others

It is possible that the motor belt may have become misaligned due to the fall. Check to see if the belt is aligned properly on the motor pulley. If it is not, realign the belt and try running the treadmill again. If the problem persists, you may need to replace the motor belt.

Hello, How old is the belt? It is possible that you might need a new belt. Just like a rubberband, it can stretch and with age, it starts losing it's elasticity. If that's the case, then the belt would fall off.
I would check with the manufacture to see if they have replacement belts. They can't be that expensive and it would be worth a try.
Hope this helps.

Best wishes.

I have a Hoover canister vacuum it works great.
I think you have the right idea. Good Luck!

remove the lower pulley (crank pulley and balancer assembly)
and inspect it. if any problems replace it.

It sounds like you either have a loose walk belt or a slipping front drive pully. The walk belt shoould be tightened so that you can pull up on the edge of the belt about 2 inches. If that is OK, pull the motor cover, start the treadmill and walk trying to stop the belt with you feet. Watch the drive belt this time (the small one going from the drive motor to the front drive roller), if this belt stops, you need to tighten motor, or replace if it is older/wornout. If the drive belt keeps turning fine, watch the front roller and see if the pully connected to the drive belt keeps turning while the roller connected to the walk belt stops, if so you need a new front drive roller.


Hope this helps

Your unit has likely one of 2 problems. It most likely needs a new motor belt installed. The micro V belt can be ordered from ICON for about $20. The other possibility is the walking belt tension is too loose. Lift up the edge of the walking belt firmly in the middle and you should be 2-3 inches above the walking board. Don't overtighten the rear roller screws to increase the tension beacause it will make the motor work harder and if it is a worn motor belt, the extra tightening won't make much of a difference.

Gravity holds the motor in place and the weight of the motor keeps the belt taut. If your belt is rubbing because the motor is too low, your belt may be too long. Have you replaced it recently? Also check that the bolts holding the motor to the motor mounting plate are tight. If the motor is shifting in use, that's not good...

Assuming this is a Delta 36-444, the manual is here. See pages 10-14 for motor setup instructions to make sure yours is setup properly.

Safety note: as with any power tool, unplug it before you start working on it.

If you need more help, please ask. If this answer was useful, give it a thumbs up.

spin all the pulleys by hand with belt off, make sure none are seized.

Couple of things to check:

is there any sign of wear or stretch on the belt? (even if you can't see anything, you might want to try replacing the belt if there's no sign of a cause anywhere else)

are you putting the belt back onto the correct part of the spindle (adjust until the belt rides along the cetreline of the wheel on the back of the drum when you turn it by hand)?

are the motor spindle and the wheel on the back of the drum in line with one another (check the motor is properly on it's mountings)?

is the motor spindle complete (I have seen one with the last half inch broken off, making the belt fall off the end)?

is there any damage to the wheel on the back of the drum (look in particular for cracks in the spokes where they meet the hub casting)?
