The Multiquip 502339880 Engine Mounting Plate is a genuine OEM component designed for the MDR-9GH ride-on power trowel. Sourced directly from Multiquip, this plate ensures the engine is secured to the machine frame exactly as the manufacturer intended, maintaining proper alignment between the engine and drivetrain. If you're servicing or rebuilding an MDR-9GH, replacing a damaged or cracked mounting plate with the correct OEM part is critical to keeping all downstream components in proper working order.
Key Features
- Genuine OEM Construction — Manufactured to Multiquip's exact material and dimensional standards, ensuring the structural integrity required to hold an engine securely under sustained vibration loads.
- Direct-Fit Replacement — Bolt holes, mounting surfaces, and profile match the original MDR-9GH frame interface, allowing straightforward installation without modification.
- Confirmed MDR-9GH Fitment — Engineered specifically for the MDR-9GH ride-on power trowel, eliminating guesswork when ordering a replacement.
- Maintains Engine Alignment — A correctly fitted mounting plate keeps the engine positioned precisely relative to the trowel's drive system, preventing premature wear on belts, couplings, and bearings.
- Structural Durability — Built to withstand the continuous stress and vibration inherent in ride-on trowel operation, resisting flex and fatigue over extended service life.
The engine mounting plate is the structural interface between the engine and the machine's main frame. It holds the engine in a fixed, precise position so that power is transferred cleanly to the trowel's drive components without misalignment. When a mounting plate becomes cracked, warped, or stripped at its fastener points, the engine can shift under load — causing vibration, accelerated wear on connected components, and potential engine damage. Replacing a compromised plate promptly keeps the MDR-9GH operating with the stability and control that ride-on finishing work demands.
