What is the direct replacement for my engine?

There are many variables that come into play when replacing an existing engine with a new one (shaft extension, mounting base, overall fit, etc.).

PLEASE NOTE: The engines listed in this catalog are meant to fit a wide variety of equipment and may NOT necessarily be the exact engine you have currently on your equipment or the one that you are planning on purchasing.

Not every engine we manufacture is shown in the replacement catalog, but one of the "service replacement engines" listed may fit your application. Be certain to measure your current engine/equipment and compare these measurements to the specifications listed in the catalog to determine the best replacement for your current engine.

However, comparing an engine in this catalog to one with a similar horsepower and engine name will provide a general idea of the specification.

If you determine that a replacement for your engine is not possible and you would like to repair the current one, your engine's Illustrated Parts List is available for download from our website. Please visit our Operator's Manuals & Illustrated Parts Lists page and enter your engine numbers into the search fields.

To purchase parts online, visit our website’s Repair Parts section. This area of our site has all the engine parts (starter motor, crankshaft, piston, etc.) which are sold directly through Briggs & Stratton.

A good source for engine specifications and technical servicing information would be a Briggs & Stratton Repair Manual. The correct Repair Manual for your model engine is often listed in your engine's Illustrated Parts List.

Other helpful maintenance and instructional guides such as our Small Engine Care & Repair Manual - #274041 can also be ordered through this area.

In any case, since Briggs & Stratton does not sell engines factory direct, and to ensure that your replacement engine will fit and perform properly with your existing application, please consult a local Briggs & Stratton Authorized Dealer.

For your convenience, we offer three easy ways to locate your nearest Briggs & Stratton Authorized Dealers:

Use our website's Service Center Locator.

Call the Briggs & Stratton Automated Hotline at (800) 233-3723. This hotline is available 24 hours a day / 7 days a week and features voice recognition technology to assist you in finding the Briggs & Stratton Authorized Dealers in your area.

Engines are available for online purchase through Parts Nationwide.

Engine Power Rating Information

The gross power rating for individual gas engine models is labeled in accordance with SAE (Society of Automotive Engineers) code J1940 (Small Engine Power & Torque Rating Procedure), and rating performance has been obtained and corrected in accordance with SAE J1995 (Revision 2002-05). Torque values are derived at 3060 RPM; horsepower values are derived at 3600 RPM. Actual gross engine power will be lower and is affected by, among other things, ambient operating conditions and engine-to-engine variability. Given both the wide array of products on which engines are placed and the variety of environmental issues applicable to operating the equipment, the gas engine will not develop the rated gross power when used in a given piece of power equipment (actual "on-site" or net horsepower). This difference is due to a variety of factors including, but not limited to, accessories (air cleaner, exhaust, charging, cooling, carburetor, fuel pump, etc.), application limitations, ambient operating conditions (temperature, humidity, altitude), and engine-to-engine variability. Due to manufacturing and capacity limitations, Briggs & Stratton may substitute an engine of higher rated power for this Series engine.
