Quick question.... What model engines cross parts

[vidio1]

Will an exhaust manifold from a D722 fit a D1105 ?

Your best bet would be to ask a dealer. I asked my dealer the same question about a D722 and a D902. Those two are the same exhaust manifold, but I don't know about the one you are asking about. My dealer even printed the assembly diagram for me, for free.

No not even close.

There is also several different intakes for the D1105, so it would help to know what one you need.
What is it going in or what is it out of?

Re: Quick question

I had the crazy idea to turbocharge my tractor. After I saw a couple of posts on here with write ups I thought I'd start scrounging for parts.

It has a D1105 which was also offered as a turbo version in some equipment. With what little info I can find between them, it seems like there were only minor differences between the 2.

I've been keeping an eye out on EBay for factory manifolds. The hard part seems to be finding the cast iron part that connects between the turbo exhaust and exhaust tubing.

I've found odds an ends I'm looking for, but usually they're for a D722, that's why I was asking.

I've seen the D1105 listed as a 05 series and the D722 as a super mini but wasn't sure what that meant.

Are these engine classes like a small block chevy or big block chevy where most hard parts are interchangeable?

Thanks for the replies.

Yes kind of, most of the Super mini series parts will interchange with other super mini's, and most 05 series will interchange with other 05's.

To add a turbo to it, you don't need to change the exhaust manifold, just add the adapter to it to go from the square to rectangle of the turbo. I've seen the adapters on EBay.

While I've got someone answering my silly questions, thank you for that by the way, how is my injection adjusted? I've seen pics people posted that included a cap being removed, adjustments made and a nut retightened. I've also read about shims being removed to increase fuel volume.

Others will correct me if I'm wrong.... but I think you have it backward. The capped adjustment you're referring to turns up/increases movement of the rack allowing for more fueling or something to that effect. The shims are how you "time" when the IP sends fuel into the cylinders.

Yes you have it mostly right.

On most Kubota engines, there is 2 capped adjustments one is a fuel rack adjustment, the other is a govener adjustment, get the 2 off enough and you will shell a motor pretty quick.

The shims under the injection pump are for setting timing.

OK, thanks for that. I'll have to dig into a service manual before I start this project.
