The 9921504 spring washer is a specialized fastener component designed to provide continuous tension in bolted connections within the Elite 3000 sprayer. Unlike flat washers, a spring washer has a slight conical shape or split that creates a spring action when compressed. This action helps maintain clamping force by compensating for minor loosening due to vibration, thermal expansion, or settling of components. It is commonly used in areas subject to dynamic loads, such as motor mounts, pump assemblies, or cover fastenings. The washer is made from spring steel or other resilient materials to ensure long-lasting elasticity. Over time, spring washers can lose their tension due to fatigue, corrosion, or over-tightening. A worn or missing spring washer may allow fasteners to loosen, leading to increased vibration, noise, or component misalignment. Symptoms of a problem include visible loosening of bolts, rattling sounds, or signs of movement between assembled parts. Replacing a worn or missing spring washer with this genuine part restores the locking ability of the fastener. This simple component plays a crucial role in maintaining the integrity of the sprayer's assembly. Using the correct washer ensures that critical connections remain tight and reliable throughout operation.
