The Multiquip JDM801821 Fan Belt Sth Trowel is a genuine OEM component designed for the STX55J6 hydrostatic ride-on power trowel. Sourced directly from Multiquip, this belt is manufactured to the exact specifications required by the STX55J6, ensuring the cooling system operates as intended. If you are servicing or restoring a Whiteman STX-series ride-on trowel, the JDM801821 is the correct OEM replacement to reach for.
Key Features
- Genuine OEM Construction: — Manufactured to the exact tensile strength and dimensional profile required by the STX55J6 engine cooling circuit — no guesswork on belt stretch or cross-section.
- Direct-Fit Installation: — Designed to drop onto existing pulleys without pulley adjustment or bracket modification, matching the original belt path of the STX55J6.
- STX55J6 Fitment Confirmed: — Verified for the Whiteman STX55J6 super-sized hydrostatic ride-on trowel series, so you can order with confidence.
- Consistent Cooling Performance: — A correctly tensioned, properly sized fan belt maintains steady airflow across the engine, preventing overheating during extended finishing runs on large slabs.
- OEM Part Number Assurance: — Part number JDM801821 is the exact Multiquip catalog reference, eliminating cross-reference errors when ordering for fleet maintenance or repair.
The fan belt on a ride-on trowel drives the engine cooling fan, maintaining airflow to keep operating temperatures within a safe range during continuous use. A worn, cracked, or snapped belt reduces or eliminates that airflow, which can cause the engine to overheat rapidly — particularly during long finishing passes on large pours. Replacing the belt at the first sign of fraying or glazing keeps the engine protected and the machine running through demanding schedules.
