I have a 73 7HP ariens. It runs well, however it would be nice to have an engine with a stator on it for a light. I know the 8HP model that was made in 73/74 had this, however they were not all fitted with the stator. I have been unable to find a 8HP motor anyways. I haven't been trying really hard, but also have looked a little over the last couple years.

Is there a newer (just newer than the 10,000 series) tecumseh engine that would be pretty close to a drop in replacement that would have a stator? It can be more than 8HP as well.

Thanks for any input!

Most Tecumsehs with a stator are 8hp and larger. You have to use the "Other" set of mounting Holes that move the engine back a couple inches. Just did that on a 73-4 yesterday using a 9hp I pulled from a craftsman. Post Your Location, and maybe a member can help you out. Good Luck, those are nice Machines...BTW, Just for the record, I hate soccer.

HAha. THanks! I'm assuming, to make things easier, I would want to get a Tecumseh engine. Anything in particular I should be looking for on these other than the HP and stator feature I'm looking for?

You'll need one with the same size crank, 3/4" so you can use the same pulley and belt. You might have to modify the air box to get clearance for the chute crank.

That's no big deal. I appreciate the help! I am definitely capable to a pretty complicated "swap", but don't really want to take on anything too extensive as my time is a bit limited these days.

Another thing to consider is a Predator engine from Harbor Freight for $99....3/4 shaft, bolt holes and crank height the same. No stator, but get a battery powered light and you're in business.

Cran, Agreed with the Predator being a good option, but You forgot to mention Chute Crank Mods Needed for that swap.

What is the upper end for HP Rating on a Tecumseh before I'd run in to other issues w a swap due to size of the engine or shaft size?

My 1973 Ariens had an 8HP Tec on it that I repowered with a Predator 212. The crank for the chute had the 2 u joints, not the 1 piece rod found on the 7HP models. All I had to do for clearance was to bend ever so slightly the standoff for the chute rod for clearance. Works fine.

Here's a Typical Crank mod the way I do it on a Predator Swap. When Done with the Joints "In Phase", it cranks like Butter.

You need the one having the same crank size so that you can use the same belt and pulley.



Did you happen to read post #4 in this thread?

I think you could fit most any Tecumseh on it....they have only two bolt patterns and your machine is drilled for both....not difficult finding a 1 inch pulley for the bigger machines...Tractor Supply has a good selection I've used.

It appears getting a new pulley won't be an issue. I see tecumseh made the "winter" engine up to 13hp. Any reason to NOT to throw a 13hp motor on this thing?

13 is Overkill. 8-10 w/impeller seal is Plenty

I have a 24 inch Ariens with a 12 hp Tecumseh...tall chute, impeller kit and 3.5 inch drive pulley on the impeller. Overkill....but it throws to the moon and nothing slows it down. A 10 hp Tecumseh is a nice swap for that machine.

Haha. Awesome. I'll probably look for something 10 or more HP. If I'm going to put the work in, I'd like it to be completely unstoppable for a 24" width blower. It might be a little more work than I originally was thinking, but I'm feeling a bit inspired now.
