I would like to change my 3020G over to a diesel. Needs an overhaul. Any engine application that will fit other than the standard 3020 block? We have a Worthington Tractor near but they tell me they rarely get a good one in.Thanks.

Check with Cummins about putting in a retrofit engine. They have kits for some tractors. Call these folks: Kinze (Jim Spaid) in Iowa-319-668-1300. Steve Mallicoat at Cummins Great Plains-319-366-7537.

Oh, by all means, if you really want to completely ruin the value of your tractor, put a Cum-A-Part in it!! A Cummins conversion will only cost you about what you could buy a good complete 3020 diesel for, or even more. The above post is the dumbest thing I've heard on this board yet!!

It can be done. If it is an old style, you can install a 219 or 239 non-turbo JD engine. If it is a console model you can use a 239T or 276T engine. The 239T should run 80-85hp the 276T should run 100+ HP. For either application you will need a 2510 Hyd. pump mounting bracket, A 4030 bellhousing adapter plate, and do a little bit of adapting for the rear frame to bellhousing bolts. A shorter tack cable(attaches to bellhousing instead of the side of the block) and some adapting to throttle linkage. You will also need a second battery box and associated cables. This may not keep the "correct police" happy but it makes a real good running little tractor with a much wider power band than the original 3020 diesel engine. A trip to your local salvage yard should fix you up with the needed pieces.

I saw a kit advertised to do this, don't remember where. It was about $3000, and did not include the engine. What flywheel, clutch, and PTO arrangement do you use?

It will cost less $$$ and be less grief to sell the gas 3020 to a collector purchase a diesel.

Hello
A 3020 is a collector JD model? If so great as I have one and plan on selling in fall.
What are some of the prices on them? Have a cab on it and would like to get the most out of it.
thanks
jack

G Taylor, he probably just wants the fun of changing his engine to a different one. Is is HIS tractor. Not everyone wants a worn out 3020 gas for a collector tractor. He might put on an alternator just to offend everyone& I hope he does.

The two cylinders were 20+ years old when collecting took off in the early 80's.The 20 series New Generation are all 30+ years old now. Everyone wishes they had purchased two cylinders when they were just old junk, history will repeat it's self again with tractors too. Does it every generation with cars as well. While a typical worn out 3020 or 4020 gas makes OPEC giggle with delight they can be repaired/set-up. Turn the manifold heat on, use a 195F thermostat, properly rebuilt carb/float-needle & upgraded ignition. Then tune the timing & mixture on a dyno for as advanced & lean as possible without detonation or missing from idle to full load. The early oil-bath aircleaners are almost always 1/2 plugged too. A properly done alternator conversion is one thing, the typical blotched job with burned wiring & hours of frustration are the norm. Isn't worth trying to save a few bucks just to risk a amature's electrical mess instead of rebuilding the generator.
