Installation and Maintenance

Replacing the seal is an operation that should not be taken lightly. We recommend regular inspection of the seal condition, especially after the winter season. Before installation, ensure the shaft is clean and free of scratches that could damage the new seal. Tightening precisely according to the engine manufacturer's recommendations will prevent early failures.
