Cat 165749/Cat Pm 102 Drum Throat Seal

CAT 165749 drum throat seal is an original sealing element used in the drum section of Caterpillar PM series asphalt milling machines. While it prevents oil and grease from leaking out of the drum throat, it also prevents dust, asphalt particles and foreign materials from entering. In this way, it extends the life of the bearings and drum components and contributes to the trouble-free operation of the system.

Manufactured from durable rubber and composite material, the throat seal is resistant to high temperatures, pressure and friction in severe job site conditions. Since it is designed in original dimensions, it is fully compatible with Caterpillar drums. Replacing it at regular maintenance intervals ensures high performance and long service life.

This part is a critical sealing component for reliability in the drum system of milling machines.
