The FAAC 4900605 Swivel Joint Kit is an OEM replacement part designed for FAAC 422 and S450H hydraulic swing gate operators. This part includes the swivel joint itself along with the nut and lock washer required for installation. Its purpose is to provide a pivoting connection within the jointed linkage or connection point inside the hydraulic cylinder/actuator, allowing controlled movement without binding.
Manufactured to FAAC’s original specifications, this swivel joint ensures that the mechanical linkage maintains proper alignment and sealing under normal gate operation. Over time, swivel joints may wear, leak, or allow excess play, which can degrade performance, cause leaks, or generate noise. Replacing worn swivel joints helps maintain smooth, quiet operation and prolongs the life of the operator.
Switch off all power to the operator and ensure hydraulic pressure is relieved before working on internal paddings or joints.
Remove covers or panels necessary to access the existing swivel joint.
Loosen and remove the old swivel joint, nut, and lock washer. Inspect the mating surfaces for wear, corrosion, or damage; clean if needed.
Fit the new FAAC 4900605 joint into its mounting point. Insert the nut and lock washer, ensuring they are seated properly and oriented as intended.
Tighten to the torque specification provided in FAAC’s parts manual. Do not overtighten (to avoid damaging threads or deforming parts) or undertighten (which could allow the joint to loosen).
Reinstall any removed parts / covers. Restore hydraulic pressure (if relevant) and power.
Cycle the gate open / closed several times, observing the new joint under load. Check for smooth motion, absence of play or wobble, and listen for unusual noise. Also check for leaks around the joint area if it interfaces with hydraulic components.
When replacing the swivel joint, inspect adjacent components (pins, linkages, mounting brackets) for wear; replacing one joint while others are worn may not fully solve issues.
Use anti-seize or appropriate lubricant on threads if recommended by FAAC, especially if exposed to moisture, to prevent seizure or corrosion.
Periodically re-check the joint tightness after some cycles (first few uses) to ensure the lock washer is doing its job.
Keep the joint clean; dirt, grit, or rust can accelerate wear or impair motion.
Store spare swivel joints in a clean, dry environment to avoid rust or corrosion before installation.
Genuine FAAC spare part, built to original FAAC specification.
Comes with locking washer and nut to ensure secure assembly and prevent loosening under vibration or movement.
Proper installation helps avoid excessive wear, leaks, or failure of mechanical connection that could cause malfunction.
Use only with compatible FAAC models (422, S450H) to maintain safety and performance
