Pro-Tips for Replacing your CX1023E Filter:

System Flush: Before installing the new WG9725230042, thoroughly flush the hydraulic clutch line to remove old, contaminated fluid which can damage new seals.
Air Line Inspection: Check the pneumatic supply lines for any moisture or oil carryover from the air compressor. A clean air supply is vital for the servo’s internal valves.
Bleeding the System: Once mounted, bleed the hydraulic circuit starting from the master cylinder down to the servo to ensure zero air bubbles are trapped.
Seal Check: Ensure the push-rod is correctly aligned with the clutch release fork to avoid side-loading the internal piston.
