The Multiquip 502403940 Chain Cover is a genuine OEM component designed for MDR-9DYE, MDR-9D, and MDR-9GH power trowels. Sourced directly from Multiquip, this part meets the same specifications as the original, ensuring a correct fit with no guesswork. It is a direct match for the units listed, making it a straightforward swap during scheduled maintenance or after damage to the existing cover.
Key Features
- Genuine OEM Construction — Manufactured to the original design spec, so material thickness and mounting geometry match the factory cover exactly.
- Direct Bolt-On Replacement — Engineered to align with existing mounting points on MDR-9 series trowels, using the same hardware and attachment configuration as the original.
- Confirmed Fitment — Compatible with MDR-9DYE, MDR-9D, and MDR-9GH power trowels; cross-reference part number 502403940 before ordering.
- Drive Chain Protection — Shields the drive chain from concrete splatter, debris, and impact that can accelerate wear on drivetrain components.
- Operator Safety — A properly fitted chain cover keeps rotating drivetrain components enclosed, reducing exposure risk during operation.
The chain cover on a power trowel encloses the drive chain that transfers power from the engine to the trowel blade assembly. By containing the chain, the cover protects it from abrasive debris, moisture, and concrete buildup that would otherwise accelerate wear and lead to premature chain failure. A cracked, broken, or missing cover not only exposes the drivetrain to damage but also creates a hazard for the operator, making timely replacement an important part of routine trowel upkeep.
