The Multiquip 43140-68 Radiator Lower Isolator Mounts are a genuine OEM component designed for STXDF series ride-on power trowels. Sourced directly from Multiquip, these mounts deliver the exact material grade, durometer, and dimensional profile specified for the STXDF platform. As a genuine OEM part, 43140-68 ensures the radiator is seated and isolated exactly as engineered, maintaining correct positioning and vibration absorption throughout the machine's service life. If your STXDF is showing signs of radiator movement, coolant line stress, or excessive vibration transfer at the radiator mounting points, replacing the lower isolator mounts is a direct and cost-effective fix.
Key Features
- Genuine OEM Material Specification — Manufactured to Multiquip's exact compound and durometer rating for isolator mounts, ensuring correct compression behavior under engine and blade vibration loads.
- Direct-Mount Replacement — Engineered to drop into the existing lower radiator mounting positions on STXDF trowels without modification to the mounting hardware or radiator bracket.
- STXDF Series Fitment — Confirmed fit for STXDF dual-fuel ride-on power trowels; verify your model and serial number before ordering.
- Vibration Isolation Integrity — Properly functioning isolator mounts absorb engine and operational vibration before it transfers to the radiator core and coolant lines, protecting against premature fatigue cracking.
- Coolant System Protection — Worn or collapsed lower mounts allow radiator movement that stresses inlet and outlet hose connections, increasing the risk of coolant leaks during operation.
Radiator lower isolator mounts are rubber or elastomeric cushions positioned at the base of the radiator to absorb vibration and prevent direct metal-to-metal contact between the radiator and the machine frame. On a ride-on trowel like the STXDF, where engine vibration and blade rotation create constant dynamic loads, these mounts play a critical role in protecting the radiator core and connected coolant lines from stress fatigue. When isolator mounts degrade — hardening, cracking, or collapsing — the radiator loses its cushioned support, leading to increased vibration transmission, hose wear, and potential coolant system damage over time.
