Hi Kubotaman, here is a link to the post. It does not give much detail other than to tell that he did the mod. The little little jeep he put it in is pretty cool. It would take some pretty big ambition/kajones to do the mod, I mean that is some pretty one off prototype heavy modding going on. I would really like to see it. If you have a large supply of engines, I guess it would not be so bad. My first thought was do we have enough oil pump capacity, especially for our engines. There is quite a bit of extra oil load, with added turbo, wet vacuum pump, then the oil squirters.

Repowered my jeep with kubota turbodiesel - OrangeTractorTalks - Everything Kubota

 

I got home middle of the week. I am back at it. just a small update. For the serpentine pulley, I opted for a big washer plate welded to the hubcity splined adapter on the front, and it has 3 holes drilled to pick up the 3 already tapped holes in the Harmonic balancer. Then I drilled the crankshaft nose, to tap the crank nose for 1/4-28. So far it seems ok.

 

baby steps today. I am about 90% done with the accessories, at least I hope. I still need to sort out a tensioner for the the AC comp, or a idler pulley tensioner for it, but the alignment on the AC compressor came out OK I think. I will have to give it a test run to make sure.
Now I can get back to work on finishing the trans adapter

 

appreciate the process shared as it would too help me in going out with it .. now the time i am following and trying it

 

Looks good!

 

I started back into the trans adapter plate. It does not look like much, but I got the hollow dowels installed, and all but 3 of the trans side bolts finished. I re-checked my centers and all look ok. My mill is too small to get all the transmission mount holes done in one set up that is why I stopped. I am also measuring and recording where all the holes are. The CAD drawing I got was not correct for my bellhousing.
When I take it apart tomorrow I will try and get some better pics of the process.
I need to start shopping for a intercooler, and planning motor mounts

 

pretty full day in the shop today. The adapter plate is finished, I need to get some longer bolts for the adapter to the block, and I need to weld the little dowel pins I made into the steel bellhousing plate.
Then I guess tomorrow I will start on the flywheel
It is coming along

Looks great! Won't be long now!

 

hey FTE, Thanks for the support. I did not think about my adapter thickness being too fat for the bolt heads to not hit the flywheel. I am at 3/8 steel plate where everybody else is 1/4" I believe. That extra 1/8th is going to cause my bolt heads on the adapter to hit the flywheel. I needed new longer bolts anyway, but now I need to do some extra work somewhere.
Lots of choices for where to remove the extra metal. new countersunk screws seems like the second least amount of metal to remove.
Shaving the heads off the new longer regular bolts and using locktite instead of the lock washers is probably the least amount of metal to move?
I wanted to leave the flywheel as thick as possible, that was the thinking behind the thicker trans adapter. So facing both sides of the flywheel does not sound like much fun. However maybe it could work out if the Kubota flywheel lip is thin enough to let me just get the trans side of the flywheel to flat, then take the rest of the needed metal off the engine side.
Well it helped to think about this while writing at least. I need to get that measurement from the Kub flywheel lip.

Now a question. for flywheel reduction. Which would be better to turn it on the lathe or face it on a mill?

On a good note. I will not have to reduce the diameter of my flywheel as the jeep is a fair amount larger than the Kubota, So I will just have to reduce the thickness.

Also for anyone working on a Kubota project's accessory drives. Sam at Lenards Diesel " parts-barn.com, now seems to have a 2 groove v-drive crank pulley to fit on the V-2203 crank nose, at least that is what it looks like

Well if my previous math was correct. I should have plenty of flywheel shaving (.68") that taking a 1/8th off the engine side will be no big deal, I just have to make sure I get it flat on both sides now

---AutoMerged DoublePost---

ok scratch removing a full 1/8 from the engine side of the flywheel that would eat into the starter ring gear. But I can get little bit from back there. I have not measured yet, but it looks like about .08-.06 or so
I just need to do it and stop writing about it
