Question and Answers

Q:

slipping belt pftl51232

A:

Thank You for choosing Sears PartsDirect.com. Glad to help out. Im looking at your model number pftl51232 and it is rare that the walking belt will stretch enough that the rear adjuster will not tighten the belt enough keep it from slipping. I would recommend that you remove the motor cover, carefully start the treadmill, and then step on the belt. Watch in the area of the front roller. If the front roller keeps turning, the walking belt has to be replaced. If the front roller and the roller pulley stop, you have to adjust the drive belt. 

To adjust the drive belt loosen the motor mount bolts move the motor to tighten the belt. Hold the motor so the belt is tight and have someone tighten the mounting bolts. Now carefully test the operation to ensure the belt is tight enough.

The instructions for replacing the belt on a treadmill have never been printed. There are so many models with different variations it would be very difficult to do. Technicians are taught the basics at training sessions and are expected to adapt to the model they are working on.

Basically you disconnect the power to the treadmill and remove the motor hood. Remove the drive belt from the motor and front roller.

Remove the side rails and the rear end caps. Remove the walking board.

Remove the adjusting bolts for the rear roller and remove both front and rear rollers.

Slide the walking belt off the right side of the rollers.

Reverse these instructions for installation of new belt.

If you do not feel confident repairing this problem yourself, then you can have it repaired at your home by a Sears technician. Here is a link for the website.
