This seal kit is designed to replace worn seals within the swing motor assembly of Volvo excavators and feller bunchers. It ensures proper sealing to prevent hydraulic fluid leakage and maintain optimal motor performance, crucial for smooth and precise boom, stick, and bucket movements. A failed seal kit will typically manifest as visible hydraulic fluid leaks around the swing motor housing and a noticeable decrease in swing speed or responsiveness.
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 sign of a failing seal kit. If left unaddressed, the leakage will increase, potentially leading to a loss of hydraulic pressure and reduced swing performance. Continued operation with a compromised seal can lead to internal motor damage and costly repairs.
Ensure the swing motor housing is completely clean before disassembly to prevent dirt ingress. Avoid using sharp tools that could scratch the seal mating surfaces during installation.
Inspect the swing motor shaft for wear or damage and clean the hydraulic fluid reservoir and lines.
