The Multiquip 502302440 Gear 57 is a genuine OEM replacement designed for MDR-9DYE, MDR-9GH, and MDR-9D series power trowels. Sourced directly from Multiquip, this gear is manufactured to the exact specifications of the original component, ensuring proper mesh, tooth profile, and dimensional accuracy for a drop-in installation. Confirmed fitment covers the MDR-9DYE, MDR-9GH, and MDR-9D models, making 502302440 the correct part number to reference when ordering for these machines.
Key Features
- Exact-Specification Tooth Profile — Manufactured to OEM tolerances, ensuring correct gear mesh and load transfer within the trowel drivetrain.
- Genuine Multiquip OEM Component — Sourced directly from Multiquip, this is the same gear supplied in original production units — not an approximation.
- Direct Installation Fit — Engineered to align with existing mounting points and mating gears without modification, matching the original gear geometry.
- Confirmed Fitment — Compatible with MDR-9DYE, MDR-9GH, and MDR-9D power trowels; use part number 502302440 to verify fit before ordering.
- Protects Drivetrain Integrity — A correctly spec'd gear maintains smooth power transmission to the trowel blades; a worn or damaged gear causes blade speed inconsistency and accelerated wear on mating components.
The Gear 57 is a precision drivetrain component within the power trowel's gearbox assembly, responsible for transmitting rotational force from the engine to the finishing blades. It works in mesh with adjacent gears to maintain consistent blade speed and torque, which directly affects the quality and uniformity of the concrete finish. When this gear wears down or loses tooth integrity, operators will notice irregular blade rotation, increased vibration, or complete loss of drive — making timely replacement critical to keeping the trowel performing at spec.
