Good to know skyrydr2. Instead of messing with the mechanical pump I will just install the electric one. Looking at the Kubota garden tractor parts diagrams, they all use an electric pump with the tank mounted under the seat. The mechanical pumps only seem to be used in the tractor models with the fuel tank mounted above the engine. I am not going to second guess the OEM design on the fuel system! My D722 has the pump block off plate, so I will just swap the pump and plate between the engines.

Had a chance to catch up in this thread. Great repower and I hope you get your fuel issues straightened out.

Yesterday I finally got to work on the Case again. Got it all wired, got the muffler installed, and mounted and hooked up the electric fuel pump. Had it running on its own for a few minutes and everything works as it should. I have one small fuel leak at a splice in the line to fix, and still have to hook up the throttle and shut down cables and find space for the air cleaner.

I hope we will get to see a video of it running soon. Sounds like a great build.

Had to work on a different project yesterday, but I did start the Case a couple of times to "test" how it starts (aka, I wanted to hear it run!) and it fires right up easy. I can only fit a lawn and garden battery in it, so 300 cca is all I have but it seems to be enough. I don't really plan to see much use for it in the winter, but it will be parked inside year round. Still looking at block heaters and will probably install one by winter.

I wanted to use a small round canister air filter for the engine (from a Kubota RTV) but there just is not enough room for it under the hood, and with the loader it can't hang out the side. Think I am going to try to make an air cleaner from a Kohler K series work.

I will get pictures soon, but other than the muffler and some wires running around it doesn't look much different. And a video will be posted once I can get it out of the shop and run it around some.

Seems like the air filters and batteries are always the hardest things to find a place for. I try to keep the intake for the air filter in front of the radiator or out of the engine compartment.

Here are some current pics.  I think I figured out the air filter this morning using a bunch of 1.25" PVC elbows.  Hoping to seal up the fuel leaks this Sunday and take it out of the shop for a test run.  Still have to make a couple of wire swivels to hook up the throttle and fuel shut off cables.  Really close now.

Here is a video of it running. Everything is finished. Of course it started to rain just as I was ready to take it out of the shop, so this afternoon I will get a video of it outside.

Slick!  I see it must still be cold up there, with that heater going.

Thanks for the photos and video. Really enjoyed them. 

Before I forget, looks like you used some plastic or nylon fittings in your upper radiator hose. Keep and eye on those after your engine comes up to operating temps. I haven't had very good luck with those as they tended to buckle under the hose clamps when they get hot. Started using long radius copper sweat fittings with good luck. 

Your engine sure sounds nice and I didn't see a puff of smoke out of her. Should last you a long time. Your loader is really quick. Kind of wish mine was a little faster. 

You do nice work.

Thanks guys. It is still in the high 30's a lot of mornings here, so the heater is needed.

Cvans- those plastic elbows are the one thing I don't like out of the whole engine swap. I plan to change to something in metal soon.

No new video, didn't have anyone to run the camera. I did run it a couple times outside for about 15 minutes each time. Temp runs right at a constant 170 degrees. This diesel has more power at a fast idle than the Onan had wide open - feels more like 20hp than 13hp! Very happy with the swap and I would do it again in a heartbeat. Now I wish it would dry up around here so I can start working it for real. I may have to start on building the three point hitch for it until then.
