How Do I Find My Direct Engine Replacement Specifications?

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, make sure to read our guide below with relevant catalogs to find the right engine replacement specifications.

PLEASE NOTE: The engines listed in our catalogs 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 replacement engine that you are planning on purchasing. However, comparing an engine our catalogs to one with a similar horsepower and engine name will provide a general idea of the engine specifications.

What is the direct replacement for my engine?

Vertical Shaft Replacement Engines

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. This catalog contains only our most commonly used "multi-purpose" engines.

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.

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