Attached The tank to a gear reduced motor, filled with soap, water and a 1000 bb’s. Rinsed and refilled a few times.
Adapter plate(s) as well as hub finished, then drilled and cut 1/4” plate for exhaust flanges.
Back in one more time, then started to work on the cable bracket so it clears the engine cover.

It is 22hp net, 27 or 28 gross.
The 3 cylinder diesel only had one 1-1/4” exhaust pipe, wonder if that’s why they had head/over heating problems?
I used two stainless “J” bends, as well as most of the original pipe to mate the new engine to the muffler.
You can also see the alteration in the shift cable bracket, the bend was cut off and flipped over to reinforce the other side.

Will the different torque and RPM curve be a problem for the clutch?

That was my first thought, I found this.
Another site listed “Torque RPM” at 2800 rpm, not sure if they were trying to say “peak torque” or not though.
Peak HP on both are at the governed 3600 rpm, peak torque on the Honda is at 2500 rpm though. So they are not the same. Not sure if the 300 RPM difference will be a deal breaker.

I blocked off the air box intake from the fan and epoxied a tube into the top of the air box, so I could connect it to the factory air intake up on the back of the roll bar vs sucking air from under the bed. Using both the original mule air cleaner element and the Honda element.
The diesel mules have two radiators, one up front and another under the seat. I built a 12 volt air compressor for our gas mule and wanted to do the same with this one but decided to use the space (and existing mounts) to mount an oil cooler and full size oil filter. This doubles the oil capacity and I can get better filters for less than the little Honda ones and a much easier location to change. Lift the seat and it’s all right there. The oil cooler/fan also had a thermostat, I connected it using a relay no longer needed for the old diesel engine.
Here you can see the air intake tube, added exhaust, pipe, flange, heat shield and the flipped/reversed section that makes up the cable bracket.
Its been too many years since I drove this one with the 3 cylinder diesel. It was when it was new and my take away at the time was that the diesel was quite loud compared to the gas one we already had. The Honda is noticeably quieter and more powerful than the Kawasaki gas twin mule we have but that one has more than 5300 hrs on it, so not a very fair comparison.
