JC991/10121: A worn seal kit can lead to fluid leaks and reduced cylinder performance. The JCB catalog reference for this aftermarket replacement part is JC991/10121. This seal kit contains the seals and o-rings necessary to rebuild a boom cylinder. A common failure consequence of degraded seals is external oil leakage, which can create slippery surfaces. Keeping the seal kit in sound condition helps maintain consistent cylinder force during operation. Verify the serial number or application, then call (562) 693-7748.

Part number variants: JC991/10121, jc991/10121
