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.

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. Repair Manuals are available for purchase from a Briggs & Stratton authorized dealer.

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.

Engine power rating information

The gross power rating for individual petrol 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 petrol 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, carburettor, 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.
