Toro 524 Snow Blower Category

Original Model: Hs50-67074B or H50-65440M

This engine has a 1" x 3" shaft. If you purchase one of the stepped shaft engines with the sleeve, you must make sure that your pulley does not have a key built into the pulley. If your key stock is built into your pulley, the sleeve will not work for you. In this case, you could possibly buy another pulley with no key stock on it. The shaft would be 3/16" shorter but this should not pose a problem.

General Disclaimer

While we may have sold many engines listed above to be used for a Toro 524 Snow Blower Category, we are NOT claiming these are exact replacements unless the product notes explicitly say so. Many original equipment engines may no longer be in production because of obsolescence or EPA regulations, so in some cases there may not be an exact replacement available. Our intention here is to show that other customers have utilized these in the equipment shown, but may have had to make some modifications to do so. If we know of any required changes, we will list those, however, some adapting during installation should be expected.
