The Multiquip 43140-57 Fan Belt is a genuine OEM component designed for STXDF series ride-on power trowels.

DHS Equipment stocks this part to help you get your trowel back in operation without delay.
Key Features
- Genuine OEM Belt Construction — Manufactured to the original tension and profile spec, delivering the correct grip and flex characteristics required for the STXDF drive system.
- Direct Drop-In Replacement — Matches the original belt routing and pulley dimensions on the STXDF, so installation follows the same procedure as the factory belt.
- Confirmed STXDF Fitment — Verified for the STXDF super-sized hydrostatic dual-fuel ride-on trowel series.
- Sustains Engine Cooling and Auxiliary Drive — A worn or cracked fan belt can cause overheating or loss of driven accessories; replacing it on schedule keeps the engine operating within safe temperature range.
- Fuel System Safety Compliance — On dual-fuel (propane and gasoline) equipment like the STXDF, maintaining all drive and cooling components to OEM spec supports safe fuel system operation under load.
A fan belt transfers rotational power from the engine's crankshaft pulley to the cooling fan and any belt-driven accessories, keeping the engine at a safe operating temperature during sustained use. Over time, belts stretch, crack, or glaze, reducing tension and slipping under load — which can lead to overheating or complete loss of driven function. Replacing the belt with the correct OEM part ensures the proper tension profile and load rating are restored, protecting the engine and drivetrain of the machine.
