This seal kit is designed to replace worn seals within the swing motor assembly of Volvo excavators, ensuring proper hydraulic pressure retention and preventing contamination. It is manufactured to meet stringent OEM standards, offering superior durability and sealing performance compared to degraded or damaged original seals. Operators may notice hydraulic fluid leaks around the swing motor or a loss of smooth rotation, which can escalate to reduced swing speed and control if left unaddressed.
Always verify with serial number before ordering.

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.
Visible hydraulic fluid leaks around the swing motor housing are the first indication of seal failure. If ignored, the leakage will worsen, leading to a gradual loss of swing speed and responsiveness. Continued operation with compromised seals can result in internal damage to the swing motor, requiring more extensive repairs.
Ensure the swing motor housing is completely clean and free of debris before beginning disassembly to prevent contamination. Avoid using sharp tools that could scratch or damage the seal grooves or the motor shaft during installation.
Inspect the swing motor shaft for wear or damage and clean the hydraulic fluid reservoir for any debris during this seal replacement.
