Belt/Idler Pulley Assembly ...

Product details
This replacement belt and idler pulley assembly fits Sharp uprights EC3620 and EC3720, also referenced to model 7831 and part #F691*. The idler pulley maintains tension on the drive belt so power transfers cleanly to the brush roll.
A worn idler pulley or a stretched belt lets the belt slip, which slows the brush roll and can leave carpet under-agitated. Noise or a slipping roll point to a tired assembly. A fresh set restores steady tension and full brush speed.
- Fits: Sharp EC3620, EC3720, model 7831
- Part: belt and idler pulley assembly, also #F691*
- Benefit: steady belt tension and brush drive
- Tip: inspect the belt whenever you service the pulley
The assembly installs onto its mounting as a direct-fit replacement. Confirm your Sharp model before ordering to keep the brush roll driving at full speed.
