How do you adjust the belt for a Weslo Cadence 815 treadmill?

On the rear of walking deck you have the left and right feet. Down the deck is at 0 degree incline, fold them up and you have a 3 degree incline.. You have no incline motor on this model.

Installing An Icon Fitness Treadmill Belt- No Exposed Roller Bolts

You can save yourself a great deal of time by following these instructions as opposed to those of the manufacturer. Please contact us if you need any further help. UNPLUG THE TREADMILL BEFORE DOING ANY REPAIR!

Step #1- Before unfolding the treadmill, disconnect the lift shock from the ball joint. Most have a small retainer clip that can be pulled with a small flathead screwdriver and then the shock can be removed from the ball stud.

Step #2- Unfold the treadmill and then remove the three wiring connectors for the incline motor and then one of the incline motor mounting bolts.

Step #3- There are two shoulder bolts that hold the entire motor tray in place. These are at the back of the motor area and must be removed to gain access to the front roller bolts. Remove the two shoulder bolts and then you can pull the motor tray slightly forward or backward to gain access to the roller bolts.

Step #4- Follow the replacement instructions included with the walking belt.

Step #5- Reverse the process of step one, two, and three to reassemble the treadmill.

There are Allen bolts on both sides of the bottom on the front (away from the console) of the treadmill. Turn one one way and the other the other way to adjust the belt. If this does not work, your belt is probably worn and stretched and needs to be replaced. See Treadmill Parts to order a new one.

lift the sides of the w/belt the hieght should be 2-3 inches. if more to loose,tighten it up. still have a issue take hood off and check the motor belt. if you find a bunch of black dust. your belt is worn or on its way out.PS you can find the belt on the web.

Check that the plastic end cap has not broken first. If it is OK, adjustment should be simple.
Start the machine running. With the allen key provided (3/16) simply tighten (clockwise) the left hand rear roller adjustment screw about 1/4 turn and observe the belt. If it is way off, you might need to turn 1/2. Let the belt do a couple revolutions before adjusting more. A very small adjustment id usually needed to straighten the belt. If it is way off, there may be a more serious problem..

Find the allen key that came with the machine. If you don't have it, you will need a 3/16" allen key to adjust the roller.
If the belt is pulling to the right, adjust the right screw by turning it clockwise 1/4 turn with the belt moving. You may need to do this more than once. Between adjustments, watch the belt closely to see how much it moves to the left.
Unless something dramatic has happened to the frame or some other part, the amount of adjustment should not be too great..

When you purchased the treadmill it came with an allen wrench to assemble the machine. That is the adjustment tool.
Inspect the rear plastic cap (the adjustment bolts are there) make sure it is not damaged. If the plastic is broken, it will need to be replaced. This job is not easy. If it is not broken, adjust the belt as follows..
If the belt is already rubbing, locate the adjustment screw at the back of the treadmill on the side that is rubbing.Adjust that screw tuning it 1/2 turn clockwise. Move the belt manually 3 full rotations.. If it is still rubbing, turn another 1/4 turn. Again move the belt manually 3 rotations. Once the rubbing stops, run the machine slowly and watch the belt from the back of the machine..

The only lube required is between the walking belt and the deck. You can get the lube from iconfitness.com. Lift the walking belt and squirt some on the deck from each side, underneath the belt in the area where you usually walk. Walk on it for a few minutes to spread the lube around.

I believe under the motor shroud on the circuit board their should be 2 pots 1 adjusts torque 2. adjusts speed try adjusting them and see if that take care of the problem if not. worse case it might be the drive motor.
