Ariens ST824 Snow Blower Category

Original Model: Tecumseh 8hp HM80-155316L

This has a 1" x 2-1/4" shaft on it. The newer OHV engines are wider than the original L-head engine but should fit. If you purchase an engine with the 3/4" diameter shaft, you will need to purchase the sleeve-34-1x220 to take the shaft up to 1" diameter. If you purchase one of our engines with the step shafts, you will have to purchase a sleeve-78-1x220 to make the shaft a 1" diameter shaft. If your key stock is built into your pulley, this sleeve will not work for you.

General Disclaimer

While we may have sold many engines listed above to be used for a Ariens ST824 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.
