Putting a Kubota D600 in my 782
 

I am in the planning stages of my repower. I have a Jacobson reel king with a D600. I was looking at different pics of the diesels on here. I assume they are all clockwise rotation? I seen a 1772 with the radiator near the dash and a 782D with the radiator near the grill. I assume they just have a different fan (either a puller or a pusher). My question is on a 782D the fan is where the PTO should be so is the PTO on the other end.

In the Jacobson the fan is on the front of the engine and the hydro pump is on the other end after the flywheel. Which means when I put it in my 782 the front of the engine will be facing the dash like the 1772. Any pictures or comments would help!

Like this.

Superduty5.9 the PTO actually sits in between the fan and the motor. I believe they only did that on the clyclops tractors. I've heard that configuration has overheating issues.

My fan is at the front of the engine and I could mount my PTO at the rear of the engine, so my setup would have to be like the 1772 to make it work.

Can you post just one pic of your actual D600. On the 782D the radiator, fan and electric PTO are all at the front of the tractor.

But the accessories (water pump, alternator) are on the front of the engine, which in the 782d, and 1782 sit facing the rear of the tractor. It is just the fan and rad that changed positions.

Okay, so this shot is the actual D600 being transplanted?

Yes, it is. So with my setup the fan and radiator will go against the dash. Is there a Cub specific fan adapter to put it on the end of the PTO? Does anybody have any pics of the front like a 782D? Thanks everybody for the help. I need to get it straight in my head so I can proceed!:bigthink:

Just to clarify things, on the 782D the radiator is on the front of the tractor. The 1772 diesel also has the radiator at the front of the tractor. The pics of the tractor you're showing must be a 1782. The next style after the 1772 moved the rad to the rear by the dash. So the 782D, 882, 1512, 1572, and 1772 rads were front mounted. I don't currently have any good pics of the front of my 782. Hopefully someone else will post 'em or else I can grab some for ya. Could get some of the 1772 as well if needed.

The flywheel end will have to go towards the front of the 782. Your hydro will need to drive from what would be the front of the engine. Cub had an adapter that bolted to the flywheel for the PTO and it has a pulley to run the fan in the diesel powered tractors. Cub also had an adapter that bolts to the front of the crank shaft pulley to attach the drive shaft for the hydro. I'm sure some of the guys can post pics of diesel cubs for you.

I thought there were only 5 Cub diesels 782,882,1512,1572 and 1772. So a 1782 is also a diesel?

If the Cub specific adapters for the fan and PTO are hard to find or expensive, do any of you see a problem if I mount it like the above pic with the fan and radiator next to the dash? Thanks guys I appreciate the help!

Yep,
The 1782 was a diesel. Built '90-'96. Had the D640 that was in the 1772. On this model, they switched the rad to the rear. They did have cooling issues. Couldn't imagine driving around on a 90* day with a hot rad right on your feet :biggrin2:.

Kubota BX tractors have the fan and radiator mounted just behind the control tower as does the 1782 so as long as the radiator is nice and clean it should work. The Cub 2182 with the Kubota gas engine also has the radiator mounted the same way and the one I have only gets up to 160-165. Maybe someone with a 1782 will chime in on this one.

Just because of the design of the 782 compared to the 1782, you'll have an easier time getting the radiator mounted and getting enough air through it if you put the radiator up front where it is in the diesel tractors in that series. The 1782 has cutouts with screens in the side panels to draw in air...adding those to 782 side panels would look pretty awful IMO.

I have the design in a PDF for the crank shaft to drive shaft adapter. Check out the Cub Cadet parts web site for what your looking for as far as the radiator setup. Good source of info.

This will be a neat project! :beerchug:



Here's a picture of my 1512...if it helps at all. :biggrin2:

A pic of my 982, even tho it's a Super it's the same amount of room in the engine compartment as the 782D.

Man, DWayne...you just made me realize my engine needs a bath! :biggrin2:

I hated to post that pic, I hadn't cleaned it up in a couple of weeks. :biggrin2:

I had a Kubota G6200 with the engine mounted like this, and it worked fine with the radiator in the back. No overheating issues.

Yes, but your hood is also vented for good air flow, 782's side panels aren't vented.

That is nasty, you better get the wax out pronto:biggrin2:

Yes, but it has holes in the dash/hood to let air in. A 782 does not, factory.


Nice Kubota, by the way! :beerchug:

Didn't see DWayne's post....:OhOh:

Unless I can come up with some rare parts it looks like it will be radiator against dash. I could put the radiator behind the grill but the fan would still be on the other end of the engine. Cub diesels rarely get parted out and a lot of NOS pieces are already gone. I'm not a machinist but I can fabricate. Any more ideas? Thanks

electic fan??

Only problem going electric on the fan is the Bota alternator is pretty anemic. I remember Matt G talking about that issue.

guys, sorry to but in but.. will a D950 fit a 82 series

Guys I'm out of ideas. I WILL make this work just need to figure some things out. So what, on a 782D where the fan is in front there is another pulley behind the PTO that drives the fan? The fan is mounted to a jack-shaft?

Let me go out and see if I can get some clear pics of the fan set up.

OK here we go. Another thing to think about is, if the radiator is by the steering column where will you put your battery or fuel tank?

Not much room back there:

Thanks DX3 for the pics. I'm starting to understand more now. Just curious is the 782D's crank a keyed 1" shaft?

It's a stub shaft that bolts on to the flywheel. It's probably 1" but I don't know for sure...never had mine off.

Any of that fan stuff could be made with steel plate and angle iron, some pillow blocks for the fan shaft, etc. Nothing overly complex about it.

I had to replace the fan bearings in my 882. I used a Grainger part #1L041. That is a .75" shaft with a 1.625" OD. Rich Patton was parting a diesel last fall but the parts may be gone by now. Like Matt said, you could fab up a piece of steel and use pillow block bearings. The blade is still avialable from Kubota but the bracket was Cub and NLA. I don't think it would be too hard to make one. Here are some pics when I did mine.

That is one thing I like about my 1782 is that it has a full-sized battery

Wondering if a high amp maybe 105 GM alternator would work and allow me to run electric fan and PTO? Isn't a factory 782D alt around 30-40 amp?

I was planning on using an elecric fan setup when i start my diesel swap. Ive got a temp switch so that it cycles on and off depending on coolant temp

Hey Todd

How did you manage to beat up that radiator? Texting while mowing again?:biggrin2:

kubota d600 fan
 

I want to move the fan and radiater to flywheel end of kubota d600 engine. looking for any thoughts and help on this project. :bigthink:

So has the OP made any progress on his diesel swap? I have a d600 out of a woods that I am think about doing the same thing with. Someone mentioned a pdf of the stub shaft above. Would they be willing to share?
