The Multiquip 42648-01 Heat Exchanger Fan is a genuine OEM component designed for MD80 and MD105 hydraulic ride-on power trowels. Sourced directly from Multiquip, this fan is engineered to the exact specifications required for proper hydraulic system cooling on MD-series machines. Confirmed fitment for MD80 and MD105 trowels means straightforward installation with no guesswork on compatibility.
Key Features
- Genuine OEM Blade Geometry — Manufactured to the exact pitch and diameter spec of the original, ensuring correct airflow volume across the heat exchanger core.
- Direct-Fit Replacement — Designed to mount directly to the existing heat exchanger assembly on MD-series trowels, matching original bolt pattern and shaft interface.
- Confirmed MD-Series Compatibility — Verified fitment for MD80 and MD105 hydraulic ride-on power trowels.
- Sustained Hydraulic Operating Temperatures — A correctly functioning heat exchanger fan keeps hydraulic fluid within its designed temperature range, protecting pumps, motors, and control valves from heat-related wear.
- Thermal Safety Relevance — Hydraulic overheating on a ride-on trowel can cause erratic blade control and unexpected drive response; replacing a degraded fan restores safe, predictable machine operation.
The heat exchanger fan draws or pushes air across the hydraulic oil cooler to dissipate heat generated by the trowel's hydrostatic drive and blade pitch control systems. On a ride-on power trowel like the MD80 and MD105, hydraulic fluid cycles continuously under load, and without adequate cooling the fluid temperature climbs rapidly, degrading viscosity and accelerating wear throughout the hydraulic circuit. A cracked, bent, or missing fan blade significantly reduces airflow efficiency, leading to overheating, sluggish blade response, and potential damage to hydraulic components.
