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.). To ensure you’re replacing your engine correctly, read our guide below.

Information regarding your direct engine replacement is available in our Replacement Engine Catalog (MS-5568). Our engine replacement catalog shows all of the service replacement engines and provides the measurements of the engines, specification information, mounting pattern and other valuable dimensions, numbers, etc.

PLEASE NOTE: Engine mounting hardware is NOT included with new replacement engines. If replacing an engine on an existing application, reusing the current mounting hardware is recommended. If the engine is to be installed on a new application, self-tapping mounting bolts are generally needed as engine mounting holes are blank. The engines listed in our catalogs are meant to fit a wide variety of equipment and may NOT necessarily be the exact engine you currently have on your equipment.

For additional information regarding mounting bolts and torque values, please review our Engine Mounting Hardware PDF.

Service replacement engine specifications for our vertical shaft models are available through the links below. These PDF files for vertical shaft replacement engines provide the measurements of the engine, specification information, and other valuable dimensions, numbers, etc. that will assist you in seeking a replacement engine.


What are the specifications for horizontal shaft replacement engines?

Service replacement engine specifications for our horizontal shaft models are available through the links below. These PDF files for horizontal shaft replacement engines provide the measurements of the engine, specification information, and other valuable dimensions, numbers, etc. that will assist you in seeking a replacement engine.


Engine Replacement Assistance

Engines are available for online purchase through Outdoor Power Direct, but if you are unsure which replacement engine can be used for your equipment, or would like to know if you can upgrade your existing engine, please feel free to ask questions by contacting Briggs & Stratton customer service.

Information Needed for Engine Replacement Assistance:

In order to assist you with locating a replacement engine and short block, include as many engine specifications as you can:

  • If replacing a Briggs & Stratton manufactured engine, provide the engine's complete, STAMPED Engine Model, Type, and Code numbers.
  • If not a Briggs & Stratton manufactured engine, provide the engine brand, power rating, and model number. (ex. Tecumseh 10 HP Model HMSK 22-22222d).
  • Equipment information including brand name, type and model numbers (ex. John Deere Model 316 lawn tractor).

If you need to modify the engine’s existing electrical system to match a replacement engine, view our Electrical schematic/wiring diagrams FAQ.

Contact Your Local Briggs & Stratton Dealer

Since we do not sell factory direct, and do not know if any of the above engines will fit or need modifications without examining the equipment, please locate and consult a Briggs & Stratton Authorized Dealer near you or by calling 800-444-7774.
