The Multiquip 21060 is a genuine OEM Cooling Fan designed for Whiteman ride-on hydrostatic power trowels and Mayco concrete pump models. This direct OEM replacement is confirmed to fit the STXD6i, HTXD6i, STX55Y6, and STX55J6 trowel series as well as the C30HDN, C30HDNI, C30HDNI Precision, and C30HDNI Zenith concrete pumps. Sourcing a genuine Multiquip part ensures the correct dimensional fit and airflow performance your machine depends on. Keep part number 21060 on hand as a service spare to avoid unplanned downtime on the pour or finishing deck.
Key Features
- Genuine OEM Airflow Specification — Manufactured to Multiquip's original blade pitch and diameter spec, delivering the designed cubic-feet-per-minute airflow to keep engine and hydraulic temperatures in check.
- Drop-In Replacement — Matches the original mounting bolt pattern and hub bore so it installs on the same shaft and fasteners as the factory fan with no rework.
- Broad Fitment Across Two Equipment Families — Verified for STXD6i, HTXD6i, STX55Y6, and STX55J6 ride-on trowels and C30HDN, C30HDNI, C30HDNI Precision, and C30HDNI Zenith concrete pumps.
- Sustained Operating Temperature Control — A correctly functioning cooling fan prevents heat soak during extended pours or finishing passes; a worn or cracked fan blade disrupts airflow and risks engine overtemp shutdowns.
- Thermal Safety Compliance — Proper engine cooling is critical on enclosed-deck ride-on trowels and pump units where restricted airflow can accelerate component wear and trigger thermal protection systems.
A cooling fan draws air across the engine's cylinder fins or radiator to dissipate heat generated during operation. On ride-on power trowels and concrete pumps that run at sustained high loads, consistent airflow is essential to keeping oil viscosity stable and preventing premature wear on internal engine components. When a cooling fan becomes cracked, bent, or detaches from the hub, airflow drops sharply and the engine can overheat — potentially causing an automatic shutdown mid-pour or accelerating long-term engine wear.
