Exmark 3290-465 Belleville Washer

Product Description

The EXMARK 3290-465 is a Belleville washer designed for use in Exmark outdoor power equipment. Also known as a conical spring washer, a Belleville washer provides axial load and maintains tension in bolted assemblies under vibration, thermal cycling, or dynamic loading conditions. This type of fastener component is commonly serviced by equipment technicians and small-engine mechanics performing drivetrain, blade, or deck assembly work on commercial and residential mowing equipment.

This washer is intended for use in Exmark lawn and garden equipment where a Belleville-style spring washer is specified by the manufacturer. It is a direct OEM replacement part suited for maintenance and repair applications where the original washer has fatigued, deformed, or lost its spring load capacity.

Installation Notes

Installation of this washer is typically performed by a qualified equipment technician during scheduled maintenance or component replacement. Disengage all blades, shut down the engine, and disconnect the spark plug wire before servicing any fastener assembly. Ensure the washer is oriented correctly per the equipment service manual, as Belleville washers are direction-sensitive.
