Ariens 926039 repower

Long time lurker. Searched a few times and can't seem to find anything on this topic.

I've inherited an Ariens 926039. Currently with a Briggs 21m314 0121e. Which melted down 4 years ago.

Among other small issues. I need to get it running to figure out what else is wrong.

I'm finding new engines. (21m324 2470) With the 3/4 crank. The current engine has a 1" crank. Also has the Ariens double belt kit with the integrated key.

The other engine is a Briggs 2100 series. That has a 1 inch crank from what I've seen. But carries double the price tag.

Is there any good way to go from 1" to 3/4" with that integrated key.

I've been told the only way to do this is to put a 1 inch crank in the new engine. Seems wrong to rebuild a brand new engine.

Ariens has told me that both the double belt kits (700/800) are both only for 1 inch shafts as well.

"The pulleys we have are only for 1 inch shafts"

Thanks
-Scott

What about something like this? Then you could consider a 3/4 inch shaft engine.

He has a double pulley that has the key already in the pulley (It's all one piece) and the key doesn't fit into the key used in the smaller engine shafts.

Sno-Tek Modded, 15"X-Track tires (Now has same X-Track tires but 13"x4" for better fit), 254cc engine LED light and hand warmers.
Snapper 6/22 sold but not forgotten. Was my first.
Ariens ST1027LE workhorse and going strong.

I've looked at the eBay and Amazon adaptors. Issue is that the key is part of the pulley.

Predator is the last ditch play. That means finding pulleys, etc.

If I can coble this together using know items. I'd be ahead. Thinking potential resale.

I've seen this blower on CL with the newer generic 1650 snow engine. So it can be done. Can it be done without cracking open a new engine is the Crux. I've messaged that guy. Awaiting a response.

I'd be ok spending money on an offset adaptor if that would even work.

Hey Bird,
Just use new pulleys on a 3/4 shaft engine, Amazon has many available.
2AK27X3/4 is close to your original ariens pulley at 2.70 diameter,
2AK30X3/4 will speed up your impeller a little bit at 3.05 diameter.
Then look up a 3/8 single groove pulley with 3/4 bore for your transmission drive.
EBay has several sellers that can get you similar pulleys, you just have to inquire about pulley id & od availability.
Electric motor warehouse has them also, I've bought many from them and had no problems at all. http://www.electricmotorwarehouse.co...ley-2ak27x3-4/

Good luck on your quest !!!

Ariens 24" 910962 7HP

Further updating.

The 2100 arrived. Of course with damage. Oil drain bent up into shroud. And throttle button bent vertical. All easy fixes.

Now for my next question. How/what is the best way to bolt this sucker down?

I've got it started on 2 of the bolts. I had to pinch them in while pushing the engine down.
Issue is the other side won't seem to squeeze in enough to work for me.

The hardware is hard mounted to the base. I haven't taken off the trans pan to see how it mounts yet.

For those who have repowered a new-ish Ariens. Is I wise to open up the holes on the engine block to allow it to drop down. Keep fighting the mounting bolts get another person to pull them together while I push?

Or figure out how the bolts mount, remove the plates and drill new holes.

Some pics for reference.

As a consolation. I think the pulley setup will line up once it's sitting flat. Just some longer belts and gtg.
Thanks
-Scott
