Outdoor Power Equipment (Lawn Mowers, Snow Blowers, Chain Saws and more) Discussions

In January of 2006 I purchased a Ariens 7524e with a Tecumseh OH195SP-73503C engine.   Last winter one of the oil plugs backed out while I was clearing my driveway and the engine siezed.  The engine is toast.  the body of the Snowblower is in excellent condition so I am trying to find a replacement engine for the blower.  The problem is this engine has the PTO.  Does anyone know of a replacement engine that can be fitted to the body without doing too much fiddling.

Thanks

I found a Techumseh engine for you. It is a OH195SA-72525 7 HP snow king at SMALL ENGINE WAREHOUSE. It does not have a fuel tank.They have 26 engines $260. They also have a OH195SA-72536  7hp snow king  ,same thing with a fuel tank $259, they have 460 in stock. They also have a OH195SA-19566 7hp snow king 160 in stock $239  Free shipping.  I hope this helps

I have an old compact 922022 that I was in the process of fitting a 5 HP MTD Tecumseh engine on that also has the reverse PTO.

I then got a good deal on a larger full size blower so stuck that in the back of my shed unfinished.

This thread brought up some ideas about me trying to reverse the transmission and converting it to a Harbor Freight 6.5 and keeping it as a backup blower.

I was looking at the transmission, and noticed the wheel axle and friction disk axles are mated with gears with essentially means they spin in opposite directs as well.

This got me thinking of pulling the 2 gears out and replacing them with sprockets and some chain.  This will make them both spin the same direction and negate the reversed PTO on the original engine.
I will also need to change the pulley from the friction wheel as it was the oldstyle dual 1/4" belts, but that is no problem.  Will also need to add 2 little guides to the top sprocket since it floats on the hex shaft.

I am not sure how your transmission is set up, but this might be an easy way for you to reverse your transmission direction and allow a normal engine to be used.

The problem with reversing the drive would be that the unit is set up to run from the 2:1 reduction reverse cam PTO. If you flipped the drive and ran from the main PTO you'd be running behind the unit as the axle RPM's would be doubled.

Shryp: The double speed may not be a show stopper.  You could set the friction disk to be as close as possible to the center of the drive plate and that would be 1.  You could crawl along at the expense of chewing off the friction disk but  even at an increased rate would take many years before it had an effect.  2 would be faster than normal 1 but with the 6.5 GX200 you’d have enough power to clear at a faster rate.  Your machine is only 22 inches not much to load into the impeller.  For massive storms  and nasty EOD you could just take a smaller cut.  For the rest of the driveway with freshly fallen snow 2 would be slightly faster than a normal 1 and not much of an issue    

   Also, to offset the speed increase you could go with a pulley change. 

 

PeteF: I think you mean the crank case cover.   Are you sure you have all the bolts out?

You can try a rubber hammer with lots of light blows on the side going from back to front.

 

Sometimes industrial razor blades work.  Those are like the old shaving blades but not so great for shaving.  Wedge it in and lightly tap it in further.  Do that at a number of places over and over. 

 

I have blades I got a flea market that were for some industrial application.  They are super sharp and very thin.  If the razor blades do not work I use those.  Worse case you could use a thin knife but only go in a short distance in many places over and over.  Eventually all the slight movements add up and the case break free. 

 

One of those motors bus708 listed might.  I only got google hits on one.  It seems to be in the same family as yours so may work.

Yes, I know about the speed change.  I was already thinking of a friction wheel adjustment to compensate and also the smallest engine pulley and largest drive pulley I could get.
Same for the sprockets, smallest  and largest .  This one is actually a 24" model.  Had an H60 engine that was locking up.  The cam PTO was freezing up in the front sump.
I had an H70 that had the crank/flywheel heavily messed up by what I can only guess was a botched points job and switched the cam/sump over and got the H60 running.
This project is not a priority since I already have a 924026 8/24 to use this year and a backup Toro 38035 35/21 that already has the 6.5 clone on it from last winter.

I should probably just dump it, but It seems to be better constructed than the Toro as well as using a lot of the same pieces as the bigger Ariens.  It is also 3" wider which I found annoying on the Toro.

I posted the idea I was thinking of more for PeteF than for myself as I am in no hurry right now.

Thanks the international cargo to Finland for an engine is about 790-1200 USD ! Crazy! and all because of aircargosafety things for a non used engine...
