I have a Nordic Track C1800 Model NTL9902.0. Do you have directions that I can print out? I have the user's manual but it does not show how to change the belt. I brought a new belt because it was slipping when I walked on it. maybe I didn't really need a new one. Do you have suggestions? We already tried to tighten.
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.
