Hydraulic leaking at the centre of your EC300D during swing, or controls acting erratically when slewing? A worn 14534535 central swivel joint seal allows hydraulic oil to cross-circuit between the upper and lower body passages, causing control confusion and system pressure loss during simultaneous travel and work operation. RITO supplies this precision swivel joint to restore isolated, leak-free hydraulic communication between the upper and lower structures.

In Stock14534535 Center Swivel Joint (Rotary Union) for Volvo EC300D, EC300DL, EC350D and EC360B excavators. The swivel joint allows hydraulic oil to flow continuously between the upper and lower structure circuits as the upper body rotates on the slew ring. Precision-lapped seal faces and PTFE composite ring seals maintain low-friction, leak-free operation across the full 360-degree rotation range under EC300D circuit pressures.

Multi-channel PTFE composite seal rings maintain low-friction, leak-free sealing at each hydraulic passage during continuous upper structure rotation under EC300D circuit pressures.
Seal bore lapped to OEM tolerance for correct seal ring radial clearance, preventing the cross-circuit leakage that causes control confusion during simultaneous travel and slewing.
Seal ring geometry and material selected for continuous 360-degree rotation at EC300D swing speed without overheating or deforming under long-duration swing operations.
14534535 covers EC300D, EC300DL, EC350D and EC360B, addressing the Volvo 30-36 tonne excavator range in one part number.
FAQ
Q: What are the symptoms of a failing 14534535 swivel joint on EC300D?
A: Travel motor slow or unresponsive during slewing, hydraulic oil appears at the centre pin area, functions that depend on lower body hydraulic supply (travel, blade) lose pressure during rotation, and oil analysis shows cross-contamination between upper and lower body circuits.
Q: Can I replace the swivel joint seals without replacing the full 14534535 assembly?
A: Seal kits are available for minor leakage. However, if the seal bore or shaft shows scoring from a previous seal failure, the damaged surfaces will cut the new seals within hours. Replace the full assembly when bore surface quality is in doubt.
Q: How many hydraulic circuits does the 14534535 swivel joint serve on EC300D?
A: The EC300D swivel joint typically handles travel forward, travel reverse, blade and case-drain circuits. Refer to the Volvo EC300D hydraulic schematic for the exact circuit assignment and port identification for your serial number range.
Q: How to confirm 14534535 fits my EC300D?
A: Match existing swivel joint part number 14534535 and confirm machine is EC300D, EC300DL, EC350D or EC360B. Provide machine serial number to our team for cross-reference.
Q: What quality options are available?
A: We provide original, OEM and high-quality aftermarket versions with stable supply capability.
