The Multiquip 1983997010 Fan Belt D640B is a genuine OEM component designed for D640B series equipment. Sourced directly from Multiquip, this belt is manufactured to the exact specifications required for proper cooling system operation on the D640B. DHS Equipment stocks this part to help you get the right component the first time, with no guesswork on fitment or compatibility.
Key Features
- Genuine OEM Belt Construction — Manufactured to the precise length, width, and tension profile required for correct operation on the D640B — not a generic belt cut to approximate size.
- Direct-Fit Replacement — Engineered to seat correctly on the D640B pulley configuration, ensuring proper belt tracking and tension from installation.
- D640B Compatibility — Confirmed fitment for D640B equipment; reference part number 1983997010 when ordering to ensure an exact match.
- Cooling System Performance — A correctly tensioned fan belt keeps the cooling fan spinning at the right speed; a worn or slipping belt can lead to overheating and unplanned downtime.
- OEM Durability — Built from materials selected to withstand the heat cycling and load demands of the D640B's drive system, delivering a service life consistent with the original component.
The fan belt transfers rotational power from the engine to the cooling fan, maintaining consistent airflow across the radiator to regulate engine temperature during operation. Over time, belts stretch, crack, or glaze, reducing their grip on the pulleys and causing the fan to spin slower than intended — or not at all. Replacing a worn fan belt with the correct OEM part restores proper cooling performance and helps protect the engine from heat-related damage.
