How It’s Used
The exhaust gasket is installed between the exhaust manifold and the muffler or cylinder head during engine assembly or repair:
-
Safety First: Turn off the engine and disconnect the spark plug wire to prevent accidental starting.
-
Access Exhaust Area: Remove any engine shrouds, shields, or components necessary to reach the exhaust mounting points.
-
Remove Old Gasket: Loosen and remove exhaust manifold/muffler bolts and carefully remove the old gasket.
-
Clean Sealing Surfaces: Clean both mating surfaces of carbon, rust, and old gasket material to ensure a smooth sealing surface.
-
Install New Gasket: Position the Briggs & Stratton 594365 Exhaust Gasket between the mating surfaces with correct orientation.
-
Reassemble Components: Reinstall exhaust manifold/muffler fasteners and torque to manufacturer-specified values.
-
Verify Operation: Reconnect the spark plug wire and start the engine; check for exhaust leaks and ensure normal engine sound.
Proper gasket installation helps ensure quiet, efficient engine operation and prolongs exhaust component life.
Suggested Maintenance
-
Inspect the exhaust gasket whenever the exhaust system is serviced
-
Replace the gasket if cracked, brittle, or showing signs of leakage
-
Ensure mating surfaces are clean and free of corrosion before installation
-
Check for exhaust leaks if engine sound becomes louder or uneven
-
Replace adjacent exhaust hardware if worn or damaged
