Is it possible to replace a gas engine on an old tractor for a diesel?

[2manyrocks]

Hey guys/gals I been thinking about getting another tractor (changing implements is too hard... LOLOLOLOL ). Thinking of the older non computerized models but reallly like the power/reliability of diesel (and power steering). So I'm thinking, could I get an older gas model and convert it to diesel? Would the transmission bolt up? Is it just swap the motors if it all bolts up or is there other things to consider?

I know the make/model would help but at this time I am just on the look out for a good tractor with a bad motor in the 30-45 ish hp range. I have liked Ford's, MF, IH etc but I am open to other american made tractors.

So as a starter... I have an old 47 8N has a gas motor not running. I think its rated for 6 volts. Was planning to sell it and get something more heftier and had power steering. Is it possible to convert that over to diesel?

I don't own one, but there are some posts here saying that the Kujke engine used on TYM/Branson tractors is still a mechanical diesel engine if that is really what you are looking for. I'm not saying it's an engine that will fit into an 8n. I'm just saying the Kujke engine apparently hasn't been ruined with a lot of electronics.

Anything is possible, if you have the money and resources.
I have learned over the years that when you buy a piece of equipment, try to buy one with features that are as close to exactly what you want as possible.

This eliminates additional expenses of conversion and helps minimize regrets of not buying exactly what you wanted.

As for the OP, I would sell and buy the diesel model you want, unless the currently owned gas version has sentimental value. Trying to retrofit a modern and non-brand matched diesel into an older tractor sounds like a difficult and long term project.

Is it possible "absolutely" if you have the time to do the research, locate and buy parts, equipment to fabricate what you can't source and finally money.

Once you start a project like this if you document what you are doing and post with pictures you are in the right place to get plenty of help. The scope and breadth of the folks on this site is amazing.

It’s possible sure but almost definitely not worth it. If the goal was a winter tinkering project that’s one thing but if the goal was saving money you’d be way ahead to just buy a tractor that’s already diesel.
