It's 1 7/16" keyway, NON TAPERED.

I can post some pics soon. I'm yanking the running motor out of the skid steer this weekend or early next week, once I've got a replacement ordered.

I think mine is tapered... But I'll re-check to be sure.. Why are you replacing it?

Although the HP may be close, the Wisconsin being a large displacement engine puts out way more torque. Don't shop by HP, shop by torque and you'll see that your replacement engine is way undersized.

That makes sense.

The Subaru/robin engines look promising. The VH4D at 1800 RPM makes 65 foot lbs peak torque. The Subaru EH90 makes over 80 foot lbs at 2000 rpm. It makes 30HP by 2500 RPM, and 35hp by 3k..

I think that repowering with a lighter engine could cause balance issues for a skid steer.

Possibly.. I could always go with a water cooled engine.

justme: Two issues, the charging system is flaky. I think it produces like 2 volts. I have a good magneto on the spare engine, but I can't swap it while the engine is in the machine because the hydraulic cooler is in the way. If I'm going to drain the system, remove the tank, etc I might as well remove the engine.

Second issue is.. or Was the starter, but I replaced that this afternoon. It was cranking very slow, until today when it stopped cranking at all.
Replacing a starter while laying on a bed of fresh horse manure.. So back to one issue.

I like the machine, it's size, how it drives. I just want a motor I can beat on for hours and hours and not worry about a cool down period or any of that nonsense. The spare motor I have has low compression, most likely from years of just shutting it off the second I was done with it. So I'd like to re-power it with a modern engine that will start in the middle of the winter, run lighting and a few fans (i.e 30 amp charging system), etc.

You need to find out the RPM rating for the hyd's. as the Wisconsin will run slower than most other engines.

Well, idle to 2800 RPM. That's the range of the Wisconsin. The machine has a foot throttle. I was playing with it today and, you really need to use the foot throttle. If I hold the throttle at say 2800 and do things the hydraulics are just way to fast. You can't slowly inch forward or back.

I had one of these machines, briefly. Spent a lot of time getting it work ready and still sold it. I think a modern engine would be great, the Wisconsin engine in mine had relatively low compression and seemed to like to run hot after awhile.

I did some research on a replacement engine, the Wisconsin is still built but I think it runs around $4000. That's why mine got sold.

Yeah, the wisconsin is the big down side to these machines. The CL40 (ford branded) is basically the same frame/hydraulics as my 30 and it uses a 4 cyl water cooled ford engine (picture attached). What is interesting is that the CL40 doesn't use a foot throttle, which makes me wonder if the valves are a little different or if I'm just used to moving the sticks and then adding power.
