The Multiquip 502303370 is a genuine OEM Gear Shaft designed for MDR-9DYE, MDR-9GH, and MDR-9D series ride-on power trowels. As a direct OEM replacement, this part is sourced from Multiquip and manufactured to the same specifications as the original component installed at the factory. Confirm your model code against the fitment list before ordering to ensure this is the correct Gear Shaft for your machine.
Key Features
- OEM-Grade Material Integrity — Manufactured to the same material hardness and dimensional tolerances as the original, ensuring the shaft withstands the rotational loads and torque demands of ride-on trowel gearbox operation.
- Drop-In Replacement — Engineered to the original shaft geometry and spline profile, allowing this part to seat and engage within the gearbox assembly without reworking the housing or adjacent components.
- Confirmed Fitment — Compatible with MDR-9DYE, MDR-9GH, and MDR-9D ride-on power trowels; always cross-reference your model code before placing your order.
- Sustained Power Transmission — A correctly functioning gear shaft maintains consistent torque transfer to the trowel blade rotor assemblies, keeping finish quality and blade pitch response where they need to be on the slab.
- Genuine Multiquip OEM Part — Supplied by an authorized Multiquip dealer, this is not a generic substitute — part number this part matches the original specification exactly.
The gear shaft is a core power-transmission component inside the trowel's gearbox, transferring rotational force from the drive system to the blade rotor assemblies. When this shaft is worn, cracked, or damaged, the machine will exhibit vibration, inconsistent blade response, or a complete loss of drive to one or more rotor heads — all of which compromise finish quality and safe operation on the slab. Replacing a worn gear shaft promptly restores the mechanical integrity of the gearbox and ensures full, even power delivery across all blade assemblies.
