CYLINDER ASSEMBLY (Crown CR121717-7)

A worn cylinder assembly can cause erratic movement or loss of holding force in the equipment it serves. This aftermarket replacement part references Crown as the OE maker and carries the cross-reference number CR121717-7. The cylinder assembly converts fluid pressure into linear mechanical motion to push or pull a connected component. A common failure consequence is internal leakage, which reduces the ability to maintain position under load. During a service check, a cylinder with external scoring or seal wear may indicate imminent performance loss. Verify the serial number or application, then call (562) 693-7748.
