Installation Guidance:
Turn off the generator, disconnect the spark-plug lead, and allow the engine to cool before beginning service. Follow the generator service manual for accessing the gasket’s installation location.
Remove the old gasket carefully without damaging the mating surfaces. Clean and inspect both surfaces before installing the replacement. Use sealant only if specified by Generac, and tighten all fasteners in the required sequence and to the correct torque.
After completing the repair, inspect the serviced area for leakage or other signs of an improper seal.
Verify the generator’s complete model and serial numbers, the gasket’s installation location, and the original part number before ordering.
