WASHER CUPPED (Crown CR73837-4)

CR73837-4: A cupped washer that is cupped can fail to maintain proper clamping force under vibration. This aftermarket replacement part references Crown as the OE maker and carries the cross-reference number CR73837-4. The washer's cupped shape provides a spring-like action to compensate for thermal expansion or slight loosening. When a cupped washer loses its tension, fasteners may back out, leading to component separation or misalignment. In high-vibration environments, a worn cupped washer can allow gradual loosening of critical bolted joints. Verify the serial number or application, then call (562) 693-7748. This part is a hardware washer category item.
