Question about Kenmore 74602 Gas Dryer
If the model number you listed this question under is correct, changing the drive belt involves the following steps (skip down to step 6 for instructions on how to route the belt on the belt tensioner and motor pulley):
1. UNPLUG the dryer and remove the lint screen.
2. Remove the two screws that were under the lint screen and lift the top panel.
3. Unplug the door switch connector plug and any ground wire that may be installed on the casing.
4. Locate the two screws that hold the front panel in place. There should be one screw on each side in the cabinet interior.
5. With the door shut, lean against the front panel and remove the two screws that hold it in place. Once the screws are removed, grasp the front panel at the top center and lift straight up to remove.
You should now have complete access to the dryer interior. Release the belt tension, by pushing the idler pulley (tensioner) to the right (away from the belt) and remove the old belt from around the drum.
If the belt has broken, this may sometimes cause the idler pulley (tensioner) to come loose. This is normal with no tension on the pulley to hold it in place. To install a new belt and re-install the pulley, follow these steps:
6. Loop the drive belt around the dryer drum with the groove side facing the drum. (Try to line the belt up with the wear marks already on the drum from the previous belt).
7. With the tensioner in your left hand, insert the clip end of the idler pulley into the grooves on the dryer bottom casing with the idler wheel pointing to your left. (The grooves are directly in front of the drive motor.)
8. While holding the tensioner in place, insert the belt UNDER the wheel with your right hand and push the wheel to the RIGHT while pulling the belt over the drive motor pulley.
If this does not explain it well enough, you can also verify by going to repairclinic.com. Click on the Repair Help link and look for the "Dryer Belt Diagrams" link under the Special Features section on the next page. Look for WHIRLPOOL and refer to diagram H (This model is manufactured by Whirlpool).
Replacement parts (if required) can be ordered on line at any of the following websites:
The part number for a replacement belt is 341241. All these sites offer great service with competitive pricing, so shop and compare. The first three sites I have listed also include helpful exploded view diagrams that can help you locate and properly identify the parts you may need. you can view a diagram of the belt and tensioner under the "Cabinet Parts" section.
NOTE: If you still have the Teflon glide type tensioner, Whirlpool recommends you replace it with a conventional roller type idler pulley. The Teflon type tensioners caused premature wear to the drive belt. The part number is 691366.
Once you have the belt installed, re-install the dryer front panel by holding it as you did previously. Line up the holes on the inside bottom edge of the front panel with the small mounting cleats on the front edge of the side panels. This can be done by yourself, but an assistant may make it easier. Once you have the front panel in place, lean against it to hold it in place and install the mounting screws.
NOTE: Don't forget to reconnect the grounding wire and door switch connector plug. Without the door switch connected, the dryer will not run.
Lower the top panel back in place and reinstall the two screws.
NOTE: Placing a piece of duct tape over the dryer vent chute will help safeguard against dropping anything down in the blower fan assembly. If you drop any screws down the chute, you will need to remove the dryer back panel to retrieve them. If you have any questions about this repair, please post back and let me know. I hope this helps you.

Before servicing the vehicle, refer to the Precautions Section.
Remove or disconnect the following:
Negative battery cable
Right-hand front wheel
Right-hand wheel well side cover
Accessory drive belts
Water pump pulley
Timing belt upper cover
Turn the crankshaft pulley so cylinder No. 1 is at Top Dead Center (TDC). Align the pulley groove with the timing mark "T" of the timing belt cover.
Remove or disconnect the following:
Lower timing belt cover
Timing belt tensioner
Timing belt To install:Align the timing marks of the camshaft and crankshaft sprockets to ensure the No. 1 cylinder is at TDC.Temporarily install the timing belt tensioner.Install the timing belt over the crankshaft sprocket, then inside the idler pulley, over the camshaft sprocket and then inside the timing belt tensioner.Apply tension to the timing belt by turning the tensioner in the clockwise direction so there is no slack in the belt on the tension side.Tighten the tensioner mounting bolts to 20 ft. lbs. (27 Nm).Check the timing belt tension as follows:
1.6L (VIN 3) engine: Push the tension side of the belt in horizontally with a moderate force, the timing belt cog end is approximately 1/2 of the tensioner mounting bolt head radius away from the bolt head center.
2.0L engine: Push the tension side of the belt in horizontally with a moderate force, the timing belt cog end sags approximately 0.16-0.24 inches (4-6 mm).
Turn the crankshaft two turns in the clockwise direction and realign the crankshaft sprocket and camshaft sprocket timing marks.
