8 HOLE SILICONE Gasket

Gasket is 1/8" thick

THE GASKET SURFACES MUST BE CLEAN AND DRY.

1.   Remove the valve cover and gasket in accordance with the Lycoming 

       procedure or in accordance with an acceptable procedure used 

       by the shop performing the installation.

2.    Clean the valve cover and the cylinder surfaces of all 

       residual material.

3.    Install P/N RG-67193-SP,  DRY.

4.    Replace the valve cover and torque the cover bolts to 25 in-lbs.

5.    Check the cover bolt torque after an engine run-up to 

       take off power or first flight and re-torque the bolts to 20 in-lbs.

       **CAUTION**     DO NOT OVERTIGHTEN.   

       It makes the gasket bulge out or squeeze out.

6.    Check the cover bolt torque annually, and re-torque 

       to 20 in-lbs, if necessary.

The gaskets are re-usable and the service life of the gasket is determined 

 by its physical condition on removal.     

If the gasket is still pliable and without cracks, tears, or deterioration, 

it may be re-used, otherwise discard.

TO REUSE GASKET:

1.   Wash briefly in hot soapy water and remove all traces of oil.
2.   Rinse completely and dry all surfaces of the gasket.
3.   Re-install using the above installation instructions.

Instructions come with the gaskets.
