Failure Symptoms

Early indicators of a failing Rotocoil Assembly include jerky or inconsistent hydraulic movements. If left unaddressed, the affected hydraulic functions may become completely unresponsive or leak internally. Continued operation risks damage to other hydraulic components due to improper fluid control.

Installation Tip

Carefully inspect the valve bore for any scoring or damage before installing the new Rotocoil Assembly. Avoid forcing the assembly into place, as this can damage the precision-machined surfaces.

Service Note

Inspect the hydraulic control valve spool and seals for wear, and consider replacing the hydraulic filter element when servicing the Rotocoil Assembly.
