ZJYXLB00066 — For Volvo Excavator Ec240B Adjust Cylinder Seal Kit

This is an adjust cylinder seal kit designed to maintain hydraulic pressure within the adjust cylinder of Volvo excavators, typically used for track or blade adjustment. It is manufactured to meet stringent OEM material and dimensional standards, preventing internal and external fluid leaks, unlike a worn or damaged seal. Operators may experience slow or uncontrolled movement of the adjustable component, or visible hydraulic fluid leaks from the cylinder rod when this seal kit fails.

Failure Symptoms

Initial signs of failure include a gradual loss of position holding for the adjustable component (e.g., track tension drift) or a slight external fluid leak. If ignored, the cylinder may lose its ability to maintain pressure, leading to uncontrolled movement or complete loss of adjustment function. Continued operation can result in significant hydraulic fluid loss and potential damage to the cylinder rod.

Installation Tip

Carefully clean the cylinder bore and rod, ensuring no dirt or debris is present that could damage the new seals during installation. Lubricate all seals with clean hydraulic fluid before insertion to prevent tearing.

Service Note

Inspect the cylinder rod for any signs of wear or damage, and check the hydraulic fluid level and condition before reassembling the adjust cylinder.
