Davenport Washington | I have a 1973 4230 that needs an engine it has the 404 non turbo engine. I want to swap a 404 turbo out of a combine I have that runs great. I have a couple of questions, can I use a radiator from a 4430, the radiator needs replaced anyway? If I can use the 4430 radiator the I could use the air box and piping from the 4430 to make everything pretty simple.
I know I need to change the oil pan and would need to change the thermostat housing, and going to replace the water pump as well.
I am looking for advice or tips from those who have done this before. TIA

Nc Ks. | I thought the 359 was only used in the 4030 and 4230s all had the 404. |

Davenport Washington | I guess I was wrong with 359 but it is a non turbo motor with the rotory pump and looks alot different then the 404 I have out of the combine |

east central illinois | Pretty sure it's a 404 |

| All 4230s had the 404 engine.
Your simplest swap would be to take just the long block from the combine. I think you'll find the combine engine used different manifolds than the 4430, so you would need more than just the air pipe(s) from the 4430.
I'm a little confused by your mention of the 4430. Do you have a donor tractor also? Buying all the odd bits that you would need could get spendy, though I question the wisdom of buying a used radiator. Pretty sure the 4430 used a different (bigger) air filter. Is there room in your 4230 for a bigger can?
FWIW, lots of 4230s got turboed back in the day, and didn't need upgraded rads, as long as you didn't work 'em too hard. Boosting the horsepower might cause more problems under the seat than it solves under the hood... |

Davenport Washington | I need a new radiator so I was just wondering if one from a 4430 would work it would be new. The 4430 radiator and air filter housing make routing for the air inlet using the 4430 piping easy and look factory. I don't have a donor 4430 but can get the needed parts. The exhaust I just need the 90 degree elbow and muffler, need a new one anyway.

Nc Ks. | 4430's had a bigger radiator than 4230. And all 30 series had too small of radiator for their size if you were pulling them on a hot day. I think your best bet would be to either use the block out of the combine and go back the way it was built, or if you need more power, just find a bigger tractor. I think you are asking for a lot of work and headaches otherwise. |

| On the Yesterday'sTractors site, in the John Deere forum is a guy who goes by the user name Tim S. I bet he'll have answers to all your questions. |

EC IL | Wouldnt the 4430 radiator be too tall & too wide to fit under your 4230 hood? |

Marion,ks | X2 on the radiator size, the fuel tank is smaller and shorter on a 4230 than a 4430 they are totally different . You would be better off to just replace te current radiator, swap motors and use the tractor like a 4230 rather than a 4430. |

| i have done the swap only i just used the manifolds off of the combine with the blower -- all used stuff.everything went well until i went to put the 4430 piping fromthe air filter to the blower.there was a big difference.the piping was bigger wouldn't fit.here is the trick-take the rubber connection from the blower inlet(90 deg. bend)then cut the pipe at the 4230 at radiator and re route the inlet air to the blower.also the thermostat housings need to be reversed to clear blower.you will find there is not nearly as much room under the hood as on a 4430.the 4430 has a horizontal air filter(i think)and larger.i had to cut a 1/4 in. radius to get the exaust ell thru the hood.ordered a new muffler and clamp from shoup.have to get your oil supply from the oil filter housing (tophole outside) --hose w/fitting. i done the swap 3 years ago so far no problems.sure took the flat spot out of the power range .it will hang in longer before dropping down on the quad range.like others said watch the heat gauge--short on radiator.good luck dogbone |

Davenport Washington | I have the complete combine engine just trying to figure out the intake piping, I havent started this project yet just trying to gather up some info. Thanks |

Jackson County, AL | Don't know if it helps but ours needed the same thing and we went with doing an in-frame ourselves. Parts and machine shop work came to ~$1600 IIRC. |

Keymar, Maryland | put a 404 out of 6600 in a 4020 plate behind water pump had countersunt screws& combine motor did not had to swap plates several other minor changes little tighter fit going back in but bought 6600 for 1200.00 worth the trouble |

|
Keymar, Maryland | our 4020 had a 4520 motor in it when we bought it with turbo transfered everything over to new one , radiator proabably to big in size ours is border line big enough for this motor with turbo we mainly run it on our mixer runs great |
