The Multiquip 501011150 Conical Spring Washer is a genuine OEM component designed for MDR-9D, MDR-9GH, and MDR-9DYE power trowels. As an authentic Multiquip part, it is manufactured to the same specifications as the original, ensuring a correct fit within the trowel assembly. This washer is a direct replacement for the original component used in these ride-on trowel models, making it straightforward to source and install. Keeping the correct hardware in place is essential to maintaining proper tension and load distribution throughout the machine.
Key Features
- Genuine OEM Construction — Manufactured to original Multiquip specifications, delivering the correct spring rate and cone geometry this trowel assembly demands.
- Drop-In Hardware Replacement — Matches the original fastener profile exactly, seating correctly without rework or shimming.
- Confirmed Fitment — Verified for MDR-9D, MDR-9GH, and MDR-9DYE power trowels; check your model code before ordering.
- Consistent Clamping Force — Maintains the preload and tension required to keep critical trowel components secure under continuous vibration and load cycling.
- Prevents Fastener Loosening — A worn or missing conical spring washer allows fasteners to back off during operation, risking component misalignment and accelerated wear on surrounding hardware.
A conical spring washer — also known as a Belleville washer — functions by using its domed shape to apply a continuous spring force against a fastener or mating surface. This constant tension prevents bolts and assemblies from loosening under vibration, which is a persistent force in power trowel operation. When a conical spring washer loses its shape, cracks, or goes missing, fasteners can back off during use, leading to loose assemblies, uneven blade pressure, and damage to adjacent components.
