How to install a Dryer belt.
This pertains to Whirlpool, Kenmore, Roper and Kitchen-Aid dryers:

If you hear a loud bang while your dryer is working, and you notice that the drum has stopped turning, chances are the drivebelt has snapped. Fortunately, replacing the belt is a fairly straightforward operation that can be handled with a few simple tools. I'll show you how the job is done on a Whirlpool or a Sears Kenmore gas dryer. The procedure is much the same on an electric dryer.
First, unplug the dryer. Lift the lint-screen cover and pull out the lint screen (Fig. 1). If your dryer has a lint screen on the inside of the door, skip this step. Then remove the two screws that are under the cover (Fig. 2). To unlatch the dryer top, insert a thin-blade putty knife between the top and front panel, about 21/2 in. in from one corner (Fig. 3). Push in on the knife to release the locking clip, lift the corner, then release the clip on the other side. Swing the top up and lean it against the wall.
Next, move to the lower toe panel. Slip the putty knife between the lower panel and the door panel at one side and twist the knife to release the clip (Fig. 4). Then release the opposite clip and lift the panel up and off the hinge springs. To support the dryer drum while the belt is being replaced, place scrap wood under the front of the drum (Fig. 5).
Loosen the two screws at each side of the bottom of the front panel about 11/2 turns (Fig. 6). Move to the top of the panel and remove the screws from the inside of the cabinet that hold the front panel to the sides (Fig. 7). Slide the old belt off the drum.
Lean the front panel out slightly and allow the drum to rest on the scrap wood support. Drop the new dryer belt between the front panel and
the drum, and loop it over the drum (Fig. 8). Then, lift the drum slightly while pushing the front panel back into position.
Replace the screws at the top inside of the front panel, tighten the lower panel screws and remove the scrap wood from under the drum. Check to make sure that the rear drum seal fits properly over the lip on the rear bulkhead (Fig. 9). Position the new belt where the old belt was, with the grooved side of the belt facing down (Fig. 10).
Now, move to the motor area and pull out the old belt. To route the new belt around the idler and drive pulley, first pass the entire belt, doubled up, under the idler pulley. Then, push the idler belt toward the motor, slip the belt around the motor pulley and release the tension on the idler pulley (Fig. 11).
Open the dryer door and rotate the drum counterclockwise a few times to make sure the belt is tracking properly (Fig. 12). Lower the top and press down at each corner to engage the clips. Lift the lint-screen cover, replace the two screws and reinstall the lint screen. Finally, secure the lower front panel and turn on the dryer for a test run.
