Multiquip 11465021551 Flywheel Washer

The Multiquip 11465021551 Flywheel Washer is a genuine OEM component designed for MDR-9DYE ride-on trowels, MVH-304DSB and MVH-402DSB heavy-duty reversible plate compactors, and MRH-800DS and MRH800DS2 walk-behind rollers. As a direct OEM replacement, this washer meets the exact specifications set by Multiquip, ensuring the flywheel assembly seats and retains correctly without modification. Sourced directly through authorized Multiquip supply channels, part 11465021551 is the same component installed during original production. If you are servicing any of the compatible models listed, confirm your model code against the fitment data before ordering to ensure an exact match.

Key Features

• Genuine OEM Seating Geometry — Manufactured to the precise thickness and bore tolerances required for correct flywheel clamping load across all compatible models.
• Direct Drop-In Installation — Matches the original mounting interface on the flywheel assembly, seating flush without shimming or rework.
• Broad Model Coverage — Compatible with the MDR-9DYE ride-on trowel, MVH-304DSB and MVH-402DSB reversible plate compactors, and MRH-800DS and MRH800DS2 walk-behind rollers.
• Protects Flywheel Integrity — A correctly fitted washer distributes clamping force evenly across the flywheel hub; a worn or missing washer risks uneven loading, fastener loosening, and accelerated wear to the crankshaft interface.
• Authorized Multiquip Supply — Sold by DHS Equipment as a genuine OEM part, carrying the same part number used in Multiquip's own service documentation.

The flywheel washer sits between the flywheel fastener and the flywheel hub, distributing the clamping load of the retaining bolt evenly across the mating surface. This prevents the bolt from biting into or distorting the flywheel, keeping the assembly properly torqued and the flywheel running true on the crankshaft. When this washer is missing, damaged, or worn thin, the retaining bolt can lose its clamp load over time, leading to flywheel movement, ignition timing irregularities, and potential damage to the crankshaft taper or keyway.
