D722...what's it worth, will it fit? - Page 2

Another thing that makes me think it's the same physical size as the D600/D640 is they are all three cylinders. If they were gonna make a larger block, they just added a fourth cylinder. My B3300 has basically the same engine, but it's a 4 cylinder. 2012 model and same engine block design, with one extra cylinder, as the Kubotas from our CC era, say 1984. Kubota also made a 2 cylinder model as well. So, I'd say it is the same size. Nuff rambling. Disclaimer: I don't work for Kubota or makes these engines so buy with caution.

Or, procure the deal Todd, and ship it my way.

I found this. Looks like the crankshaft is the same for all 3.

That page is kind of misleading/confusing. I agree that it appears that the 600, 640 and 722 use the same crank..... however over on the left hand side it doesn't list the engine size on every line. The cranks below the first line of the section marked 600 are definitely not for 600CC motors.

That's not a good way to measure. Like was mentioned earlier, when you get above the 722 the physical size changes. Kubota makes 3 cylinders that are pretty large. The D1100 is a 3cyl and it's a bigger block. They also make 4 cylinders that are smaller in CC's than the biggest 3cyl. So, going by cylinder count is not a good way to judge.

I think I may pass on it. Here is the last I have heard out of him. "It spins over and it's trying to fire up. It sounds like it needs glow plugs"...ya maybe, or injectors or a pump. I'll keep working on him but if I don't hear it run it could get expensive real fast.

Sam Mac · #14 01-22-2015, 06:49 PM

Or he has no idea how to test it.

As you know it needs a fuel pump, power to the glow plugs a fuel tank with a filter and a return line and power for the starter. When I setup that D600 you bought from me it was a bit involved setting it up to run on the bench. Had to manually preheat the glow plugs and control the fuel pump.

Sams right. Most people can't figure out how to make something run out of the machine. That's how I got the D600 I have. Kid took it out of a machine that ran, then couldn't figure out how to make it run.

Here's a though.... I traded a running V twin Kohler for mine. Maybe the guy would be interested in something of value for trade....

Ya got me thinkin on it Sam. If he'll come off the price I may take a shot at it. What do you guys think its worth not running?

Todd

Looking at the pics it looks like it's in decent condition. If it was me I'd wave $600.00 in front of him. Yeah I know it's a gamble. Should be worth that to a rebuilder for a core if it won't run. I'll go for it if you can pick it up. I'll re-power one of my 2182's with it.

I have a d722 and a d600 in my shop. I will try and take some measurements tomorrow or Saturday. I am planning on installing my 722 with a turbo in a 982 that is sitting in the shop waiting patiently.

Oak · #19 01-22-2015, 11:13 PM

Well, I offered $600 he came back at $650. Maybe I should of offered $500.

He's going to give me a call tomorrow so maybe we will work out a deal. If it runs good, I'm cool with that.

Hence my little disclaimer.

I didn't realize they made larger 3 cylinders. Was going more by the pics of the D722. Never seen one in person. Once FarmFresh measures both of his, we'll have an acurate answer and not my guestimate. I'll have to measure the block in the B3300. It's a 4 cylinder but can't remember the actual number off the top of my head.

Learned something new today.

Hindsight is 20/20 Todd.

I still think you're getting a good deal. If you peruse Epay, most on there are $800+ with alot over $1000. Not saying they are getting that much for them, but............
Should be pretty cool in the 982.
