This center joint seal kit is essential for maintaining the integrity of the excavator's center joint, preventing hydraulic fluid leakage and contamination ingress. It is manufactured to meet precise OEM sealing standards, offering superior resilience and longevity compared to worn or damaged seals. Operators may observe hydraulic fluid leaks around the slew ring area, sluggish or jerky swing function, or a loss of hydraulic power when this seal kit fails.

Cross-reference part number with serial number before ordering to confirm fitment. Keep original parts until new ones are confirmed correct. Record part numbers replaced for future reference.
Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.
The first sign of a failing center joint seal kit is often visible hydraulic fluid leakage around the slew bearing or tower. If ignored, this leakage can worsen, leading to a gradual loss of swing performance or erratic movement. The most severe consequence is significant hydraulic fluid loss, potential contamination of the hydraulic system, and damage to the slew bearing components.
Carefully clean all sealing surfaces and grooves before installing the new seals to ensure proper seating and prevent leaks. Avoid using sharp tools that could scratch or nick the new seals during installation.
When replacing the center joint seal kit, inspect the slew bearing for wear and ensure the hydraulic fluid is clean and at the correct level.
