What Does Briggs & Stratton 690970 Do?
The 690970 exhaust gasket seals the exhaust connection between the engine and the muffler or exhaust assembly. The gasket helps provide the required seal where hot exhaust gases leave the cylinder head and enter the exhaust system.
A damaged, missing or deteriorated exhaust gasket can allow exhaust gases to escape at the mounting flange instead of passing completely through the muffler system.
What Engines Use Briggs & Stratton 690970?
Briggs & Stratton identifies 690970 as fitting various Briggs & Stratton engine models. It is commonly found in parts diagrams for larger Briggs V-Twin engine configurations.
For example, Briggs & Stratton illustrated parts lists for engine models such as 40N777 and 44T977 identify reference number 883 as 690970 – Gasket, Exhaust.
Do not use only horsepower or equipment brand to determine fitment. A mower, tractor or generator may have been produced with several different engine configurations. Match the gasket using the Briggs & Stratton engine identification information.
Do Briggs V-Twin Engines Need One or Two 690970 Gaskets?
Many Briggs & Stratton V-Twin engines have two cylinder-head exhaust outlets and therefore require two exhaust gaskets. For example, Briggs illustrated parts lists for certain 40- and 44-series V-Twin engines specify a quantity of two for part 690970.
The quantity required depends on the engine configuration. Check the illustrated parts list for your exact Model, Type and Code before choosing the quantity to order.
690970 Replaces Briggs & Stratton 273485
Briggs & Stratton 273485 has been superseded by 690970. If an older engine parts manual or equipment diagram calls for exhaust gasket 273485, 690970 is the current Briggs & Stratton replacement.
Some Simplicity, Snapper, Murray and Craftsman equipment catalogs may instead show legacy numbers such as 1731214SM or 1731214. Those equipment-level references can also cross to Briggs & Stratton 690970 in applicable applications.
When Should an Exhaust Gasket Be Replaced?
The exhaust gasket should be inspected whenever the muffler or exhaust assembly is removed. Replacement may be appropriate if the existing gasket is damaged, compressed, burned, torn or no longer able to seal the exhaust flange correctly.
If an engine has an exhaust leak, inspect the gasket as well as the muffler, exhaust flange, mounting hardware and surrounding components. An exhaust leak does not automatically mean the gasket is the only component requiring attention.
How to Confirm 690970 Fitment
Briggs & Stratton identifies engine service parts by the engine's complete Model, Type and Code. Locate those numbers on the engine and use the corresponding illustrated parts list to confirm that reference 883 or the exhaust-gasket position specifies part number 690970.
