Final Drive Cover Gasket

     

Final Drive Cover Gasket  – There are two styles of this gasket.  One is double layered as shown in the picture.  Note the vent passage is only present on one layer.  This is the gasket to use with a sheet metal final drive.  The other style is only single layered but somewhat thicker.  This is fine for an aluminum final drive cover. 

 

As recommended below I use  Aviation Form-A-Gasket.  Once the cover is installed I blow a couple of puffs of high pressure air through the fill hole until I can hear air coming out of the vent.   Careful not to blow the seals out side of the final drive.

 

To ensure a good seal, coat the gasket with Permatex Aviation FORM-A-GASKET Item 80019.
