Then speed the belt up to 2 or 3 miles per hour, fine tuning the adjustment as needed. Let it run for a few minutes at the slowest speed to insure the belt stays centered. To move the belt to the right, tighten the left bolt a quarter turn at a time. To move the belt to the left, tighten the right side a quarter turn at a time. Start the treadmill at its slowest speed to insure the belt stays centered.

Tighten the walk belt evenly at the rear roller bolts until you can only lift up the walk belt on both sides, at the center of the belt, about two inches. Then reverse the procedure to reassemble.īe sure to lube the deck and center the walk belt before you tighten up the belt. Slide off the old walk belt, and slide on the new one. Once these are removed, you can then remove the deck and walk belt from the treadmill. Remove the four deck bolts along the edges on each side of the deck. Then remove the front roller, noting the position of the alignment bolt. The hidden part is that you need to remove the plastic labels to expose the other two screws in each side of the side rails (see images below). The two screws at the front end of each side rail are exposed after the motor cover is removed. Then you need to remove four screws in each side of the front sections of side rails to remove them. The rear section of the side rail slides off the tail end. The key thing to remember on this walk belt replacement is that the side rails come off in two sections. Then remove the rear roller bolts, and remove the rear roller. To do your own, first remove the end caps by removing the two screws underneath each cap. The old walk belt folded over onto itself a was destroyed. I replaced the walk belt on this Horizon CST3 Treadmill in Portland, Maine.
