John Deere 4020 Gets 7700 Combine Power Plant

[@haroldswick9962]

Great project. My Uncle built 24 tractors during the depression. Farmer's couldnt get or afford power in those days. Your vid

[@haroldswick9962]

ei shows the dedication and intelligence of farmers. Thanks.

I have a 1971 model 4320 tractor that has a engine out of a 6600 combine installed in it. I bought it that way, would of loved to seen the transfer. It runs 140 hp on the dyno.

[@matthewdavis9979]

That’s totally worth the whole video to hear it run at the end

[@andrewssoundsofthepast110]

Thanks we really like it every start is a smile

I bought a 1967 4020 myself this summer.

[@brandoncarlson4039]

i plan on doing this exact project with my '70 4020 gas, wiht the engine out of a 7720 combine.. Great insight on how to start the project. once you get the cheat sheet you will have to get it to me ha

[@andrewssoundsofthepast110]

Seems to me a 70 gas 4020 would be very low production numbers

Nice job as always Andrew. Thanks for sharing

Sounds like a 7700! I think it’s the in-line pump that makes them start like that.

Any ways i have a customer that is going to be dropping off a 4020 with a bad motor and he has the motor from a 6600 that he wants me to put the 6600 motor in the 4020. What i wanna know is what did you do about the water pump fan ? and how much do you take of on the crank pulley and what ales do i need to do to make it fit. As for the bad motor me and my cousin are going to overhaul it and keep it in till we get a tractor in with a bad motor and change it out with the motor that we overhaul

Some questions on the radiator fit. I'm currently fitting a 7700 Turbo engine in a early 4020 Diesel that threw a rod and wrecked 90% of the original motor. I'm at the point where I'm checking the radiator fit. The combine w/p shaft comes out right against the rad core. Did you have to shorten the shaft and water pump hub?. Also the lower radiator hose connection to modified crank pulley is very tight...hose will rub...did you have to alter the lower rad connection?

[@andrewssoundsofthepast110]

On this one the water pump pulley doesn’t collide bugg t if heard of guys pushing then on but just remember your belt needs to line up with on fog the grooved. I believe the front. As the lower water pipe dad did have it moved out like a half inch. My 4010 didn’t need moved

[@greatnorthernn-3154]

@@andrewssoundsofthepast110 The water pump variation I have has a longer than normal pulley hub and shaft. I'll have to shorten both by 3/4" or so. Thanks for the radiator tip...if the lower connection were tipped to the outside the hose would clear. That's a very professional job done on your tractor. The one here will end up non turbo with the fuel cut back to 90 HP or so. It's main job will be to pull a Rowse D-9 mower in the summer.
