Proform 349566 Drive Roller/Pulley

Proform 349566 Drive Roller/Pulley supports belt movement within the treadmill drive system, transferring motor rotation to the walking belt while wear can affect tracking and smooth operation.

This part fixes the following symptoms:

• Walking belt moves unevenly during treadmill operation.

• Belt slips while the treadmill is under load.

• Grinding or squealing sounds come from the drive area.

• Drive roller rotation feels irregular during use.

• Belt movement becomes less consistent at different speeds.

Belt Slippage

Quick Check: Observe whether the walking belt loses movement while weight is applied.

Fix Suggestion: Set the drive roller alignment correctly and verify belt tension.

Prevention Tip: Keep the drive area clean and maintain recommended belt tension.

Irregular Roller Rotation

Quick Check: Rotate the roller manually and note resistance or uneven movement.

Fix Suggestion: Address pulley alignment and examine the roller mounting points for wear.

Prevention Tip: Avoid operating the treadmill with excessive belt tension.

Drive Area Noise

Quick Check: Listen closely near the drive roller while the treadmill runs slowly.

Fix Suggestion: Remove debris around the pulley and correct any alignment issues.

Prevention Tip: Periodically examine the drive area for buildup and unusual movement.

Walking Belt Tracking Issues

Quick Check: Watch whether the belt shifts toward either side during operation.

Fix Suggestion: Center the belt and verify the drive roller sits squarely.

Prevention Tip: Keep the roller and belt surfaces free from accumulated debris.

Customer Experience: A customer noticed smoother belt movement and reduced drive-area noise after correcting the roller alignment and addressing pulley-related fatigue.
