oil seal - output shaft - transfer box - series - corteco

The Corteco transfer box output oil seal is an essential sealing component for Land Rover Series III 88 and 109 models. Installed on both the front and rear transfer box outputs, it prevents oil leaks while protecting internal drivetrain components. 

Manufactured by Corteco, a leading specialist in automotive sealing technology, this OEM-quality seal is designed to withstand transmission oil, temperature variations and continuous mechanical stress. 

Proper sealing is vital to maintain correct lubrication of bearings, shafts and gears within the transfer box. A worn or damaged seal can lead to oil seepage or leakage, increasing the risk of premature wear to transmission components.

Typical signs of failure include oil traces around the output flanges, gradual oil loss and contamination underneath the vehicle. Replacing the seal restores proper sealing performance and helps maintain the long-term reliability of the transfer box and drivetrain.
