Hi there. Anyhow I have a excavator that's around a 1995 model. Has a D1105 engine in it. It has very low compression will not start. I have a friend who has a 2007 toro groundmaster with a d1105 in it. My question is will a 2007 D1105 exchange with a 1995 D1105. Engines do look different. But I'm wondering if the blocks are the same. Where I can exchange parts from the two. Posted 2 pics of the motors
Will a 2007 D1105 engine replace a 1995 D1105 engine

Yep they are the same engine, just external parts have been changed.
You should be able to swap over all the parts that you need between the two.
You might not need to change some, one example, like the front gear case cover has an oil fill where the other has the oil fill on the valve cover, if you need the one with the valve cover fill, just swap the valve cover and forget about the gear case cover swap.
If you have to change the oil pan, check the pick up tube to make sure it's the same, or swap it too.

Thank you for the reply and advice. I will drive the 700 miles to go buy the engine now. Appreciate you for this!!!
My advice comes from doing several engine/transmission swaps from different years of cars, a couple swaps from stick shifts to automatics and making them like factory because I had the donor car.
FIRST, Take your time! Don't take everything apart at once on both engines and end up with part mix-ups. Get ALL the parts you might need from the donor, even if you are not sure you will need them.
I would listen to the "New" engine FIRST to make sure it doesn't have any issues or leaks. On diesels, I remove the oil cap on the valve cover at hot idle and see if there is any blow by smoke. A little bit is normal. his tells you the condition of the compression rings on the pistons.

I would rebuild the 95 engine. Make sure you keep all he big parts.... The lil 3 cyl kubotas are easy to do. You can probably rebuild the 95 for less than $700
They might be the same...or they might not.
A D1105 has a lot of different variations. The basic short block is basically the same. But in some cases that's where the similarities end.
Similarly, I'm looking at a K008 mini-excavator, with a D722 engine. It makes ~10hp, and is governed to 2050 RPM. But a D722 in my G1900 turns 3500 RPM on the governor and makes about 18hp. BIG difference; if I were to put the G1900 engine on the excavator, it's possible that the hydraulic fluid would be overheated, wheel motors turning too fast, way too much fluid volume, fuel usage goes way up, the little radiator may or may not be able to cool the engine with elevated RPM, the engine turns too fast-among a bunch of other issues.
If at all possible, just rebuild what you have. If not possible, swap all the governor and fuel injection pump parts from the excavator to the toro engine, and be sure to re-time the injection via shimming. Not hard, but slightly tedious-or it "can" be anyway.
I've known guys who've bought D1105's from excavator and then put it into an RTV1100....to find out that it only will go about 10 mph and take forever to get there, because the governor is different. All that work, just to yank it back apart...and on an RTV1100, it's not an easy task to have to do!

Hey if you can rebuild a 3 cylinder Kubota for $700 I'll send over a truck load...let me know when they are done.
The last 3 cylinder Kubota that I rebuilt I had around $1400 in parts and machine work, and that was from a running core, this didn't include any of my labor time to do any work and that would have been in the $2k range.

I also took what lugbolt is saying and factored that into my saying that it should work.
I guess i could have asked more questions, like exact models of each, but on average the Mini Excavators and Toro Groundsmasters of each of their eras both share the same running parameters.
One thing to not is that I think the Toro is running a turbo on their engine where the Original is not.
I personally would swap it over to be a turbo engine over the stock natural aspiration.
2 motor models that are particularly problematic in swaps are the D722 and the D902 as they varied a lot from model to model, and as Lugbolt said there are a ton of other parameters that can change with these motors.
If the OP runs into swap issues, I would like to hear about it, and would help him work through it.

I have the toro hear at home already. Also I pulled the engine from the toro already. Gonna pull engine from the excavator soon. See what all I have to change. I think the excavator engine is a 3000 rpm and it says on a tag 21 horse power. I think the newer toro has few more horse power then 21. The toro is a 2007 toro groundmaster 3100D. Will upload some pics
The switch over is done. It went very smooth. I only had to change few items out. From old motor to new motor. It's running very nice now. Thank you all for y'all help.

Granted it has been a few years since I last did one.... maybe prices have risen that much. Not much to em was the point. Before I drove 700 miles and bought one that MIGHT work.... I would tear down what I had and go that route. If the crank is good and there is no hole in the block... they're pretty simple machines. That's why they are so good.Hey if you can rebuild a 3 cylinder Kubota for $700 I'll send over a truck load...let me know when they are done.
