Upper Gear Seal SIERRA 18-2918

Compatible Engines

The SIERRA 18-2918 upper gear seal is a critical component ensuring the tightness of the drive system. Due to the lack of a specific list of compatible models in the source data, compatibility must be verified by the manufacturer's catalog number (18-2918) or OE number. If you have any doubts, we recommend contacting our customer support.

Installation and Operation

Replacing the seal is a simple but crucial step to prevent water from entering the gear housing. Thoroughly clean the contact surfaces of any remnants of the old seal and dirt. Careful tightening of the screws prevents leaks and extends the lifespan of the component.
