CAT 166-1495 Pin Seal is a steel-faced rubber lip seal designed for greased linkage pin joints on Caterpillar equipment. It has a specified shaft diameter of 89.85 mm, bore diameter of 106 mm and height of 8 mm. The seal helps retain grease and reduce the entry of dirt and other contaminants into moving pin joints. Caterpillar lists this part for multiple excavator models, including the CAT 320, 330, 336 and 349 series. Final compatibility should be confirmed by machine serial number and parts diagram before ordering.
Excavator linkage pins operate under heavy loads and repeated movement. Grease helps protect the contact surfaces between pins and bushings, but dirt and abrasive particles can accelerate wear.
The CAT 166-1495 Pin Seal is designed to retain grease within the joint while limiting external contamination. During operation, controlled grease movement helps flush contaminants away from the sealing area.
A damaged or incorrectly fitted pin seal can allow grease loss and dirt entry, potentially increasing wear on linkage pins and bushings.
