5. Installation Instructions (Setup)

Safety First: Always disconnect the dryer from its power supply before attempting any repairs. Wear appropriate safety gear, such as gloves.

General Steps:

1. Access Dryer Components: Carefully remove the back and top panels of your dryer to gain access to the drum, belt, and pulley system.
2. Remove Old Parts: Identify and remove the worn-out drum support rollers, idler pulley, and dryer belt. Note their original positions and how they are assembled.
3. Install New Rollers: Replace the old drum support rollers with the new WPW10314173 rollers. Applying a small amount of grease to the roller shafts can help reduce noise and ensure smooth operation.
4. Install New Idler Pulley: Replace the old idler pulley with the new 279640 or W10837240 assembly. Ensure it is securely mounted and provides proper tension.
5. Install New Belt: Carefully route the new 661570V dryer belt around the drum and the motor pulley, ensuring it is correctly seated on the idler pulley.
6. Reassemble Dryer: Once all new parts are installed and checked for proper alignment, reattach the back and top panels.
7. Test Operation: Reconnect the dryer to power and run a test cycle to ensure proper function and absence of unusual noises.

6. Maintenance

To ensure the longevity and optimal performance of your dryer and its new components, consider the following maintenance tips:

• Regular Lint Trap Cleaning: Clean the lint trap before or after every load to prevent lint buildup, which can restrict airflow and strain dryer components.
• Vent Cleaning: Periodically clean the dryer vent system to remove accumulated lint and debris. This improves efficiency and reduces fire hazards.
• Component Inspection: Every few years, or if you notice any changes in dryer performance, inspect the drum rollers, belt, and idler pulley for signs of wear, cracks, or damage.
• Lubrication: If accessible, apply a small amount of high-temperature grease to the roller shafts during inspections to maintain smooth rotation and prevent squealing.

7. Troubleshooting

If you encounter issues after installing the repair kit, refer to the following common problems and solutions:

Dryer Still Noisy After Repair:

• Check Roller Lubrication: Ensure that the new drum rollers were properly lubricated during installation. Insufficient lubrication can lead to squealing.
• Inspect Idler Pulley: Verify the idler pulley is installed correctly and is not loose or damaged. A wobbly pulley can cause noise.
• Belt Alignment: Ensure the dryer belt is correctly aligned on the drum and pulleys.

Dryer Drum Not Tumbling:

• Belt Installation: Double-check that the dryer belt is properly installed and tensioned by the idler pulley.
• Motor Function: If the belt is correctly installed, the issue might be with the dryer motor or a related electrical component.

Belt Does Not Fit:

• Verify Dimensions: The 661570V belt in this kit is 93 1/2 inches long, 0.3 inches wide, with 4 ribs and 3 grooves. Compare these specifications with your original belt or dryer's requirements. Some dryer models may require a different belt.

Plastic Components Seem Brittle:

• Handle with Care: The tri-rings and other plastic components should be handled gently during installation to prevent cracking.
• Inspect for Defects: Before installation, inspect all parts for any manufacturing defects.
