I picked up a 11 HP Yardman snowblower and I was planning on putting the motor on my Ariens ST 8\24 that has a Tecumseh 8hp HM100 on it.

The 11 HP motor is a Tecumseh Snow King OHV. It looks like the it will mount on the Ariens without a problem but, it has 2 drive shafts where the 8 hp that only has 1.

Do you know if it is possible to make it work on the Ariens with 2 drive shafts?

My mistake, it is a 924XXX, it is an ST 824. The shaff is to long and i tried to grind it this morning and it looks like it would take many hours.

So, I spoke to a local machine shop and they can turn the shaft down to 1 inch for about $50.

Now, my next challenge is to pull the motor apart and get the crank out and bring it to the machine shop. I have never torn down a motor that far. How difficult is it?

Any things to be aware of or look out for?

Replacing the pulleys would be easier. 

 

Second to that you could sell the 11.5 and dump the money into a new Chinese GX Honda clone 11hp OHV which can be had for $239.  The crank will be 1 inch with a ¼ key.  It would bolt right on with the only other mod being the belt cover.  There’s even a place to hook up your throttle cable from the dash if the 924 is an older model.

 

If you go for pulling the crank then it’s a lot of work and you should at least put in new rings and lap the valves.  You have not done that so would have to at least come up with a valve grinding tool $5-10, compound  $4, gaskets ~$10, valve spring compressor $10, ring compressor and expander ~$25 but rings can be removed  and installed without these with care $15, and new rings ~$50.  Possibly these won’t be available locally so include a few shipping charges.     Given the machining cost, rings, other parts and a few tools you’ll probably spend $150 to get the job done. 

    

You’ll have to spend a few hours watching some UTube videos on rebuilding and surf for guidebooks on rebuilding an OHV.
