IH 403 Information

d282 · Nov 16, 2009

Hello- I am starting to look for an IH 403 diesel combine, but do not really know what to look for. I have read through some of the previous posts, and know that they had a d282, or d301. Did they make many diesels? Does the 301 use glowplugs? Did the 403 stay unchanged through the years of production, or were there updates? Is there anything to look for in particular if I find one for sale? (straw walkers crack, or front axle seal etc.)

Thanks for the help.

A 403 diesel is very rare. The later 403's had the 301 diesel which used glow plugs. The basic design of the machine remained unchanged though IH did offer hydrostatic drive transmissions in the mid to later model machines along with separater shields on the sides of the machine. If you are looking to buy one look at the grain tank and the grain pan above the transmission and see if the machine is rusted out there. If it is a hydro model check the hydro to see how stout the hydro is. Check the augers and belts for wear. Having one with a robot header control for soybeans is a plus. I run a late model hydro 403.

I don't remember ever selling a 403 diesel although the 301 glow plug engine was an option. Most we sold were LPG. All 403's were basicly the same except that hydrostatic drive was offered about half way through the production run. The 403 was a very good and reliable combine for its time. The "Rice Field Special" was especially good in comparison to other rice combines.

Don't forget the switch to hydrostatic power steering and the switch from flat belt to triple "V" belt machine drive system!

we have a403 diesel, or whats left of it. it was about middle of production. motor was taken off and run on a 715 until it threw rod.

I have seen some nice 715 dsl. combines with QT sell pretty cheap, ten years newer more capacity than a 403

1968 403 · Nov 17, 2009

Mine is a 'rice special' they were a heavier, little better made machine. The spike tooth does a very good job in soybeans and small grains.

Hi Steve-

How much of the combine is left? I still need to do some more
research, but I am wondering If I could buy the instrument dash
that has the glowplug indicators, and anything else that pertains
to a diesel, thinking converting a gas to diesel, but then that
may simply not be worth the hassle.

Thanks to all that have posted. I greatly appreciate your help.
This is a picture of my current project.

I did a gas to diesel conversion on a Gleaner F and it was a good experience.
I replaced the Chevy 292 with an Oldsmobile diesel 350 V8.
A diesel V8 in a 403 would be a neat setup!
The IH 6.9 diesel would be a perfect match.

d282, i think every thing is still in the cab. it has glass fuel filter on tank that is different than 715. if you decide to go that direction let me know.

1968 403 · Nov 18, 2009

A 403 should has just as much capacity as a 715. Cylinder and feeder width are the same. The cleaning system and straw walker area are the same. The only advantage a 715 might have would be a slight increase in horsepower.

yes they are same size. main differene was 715 had cylinder and fan speeds were easier to change.

1968 403 · Nov 19, 2009

Yes a 715 cylinder and fan speed was easier to adjust but they also had many more and heavier belts and pulleys. A 403 is very simple and easy to work on. They were a tough reliable machine.

Just a point of interest in the IH Windbreaker on your Farmall. There are a few new ones listed on ebay as a buy it now. That system brings back memories, heat and dust.

steve il · Nov 20, 2009

i agree with you. i was even told by a ih mechanic that he thought the chain drive cylinders on 403 would out work the 715 belt drive. late 403 with white cabs were good machines.we have part of one. ill post serial # next week.

Hi Steve- Could you tell me where you are at in IL? I am in central
Iowa, and am interested in your remaining diesel parts. (glow plug gauge, button, and fuel filter case etc.) I was thinking of a road
trip sometime this summer if it is not too terribly far. Thanks for
your responses.

im near Olney, thats southeast il. we will be going to Minnesota this spring. or you are welcome to come down. i enjoy talking red combines. we have used 101s on up to 1480s.

Hi Steve-

I have been looking at parts books and manuals, and would
need the back of the steering wheel column, (gauge and button)
fuel tank and supports, filter and lines up to the engine and fuel
shut-off cable. If it is possible to bring on your way to MN I
would be happy to meet you anywhere. I will leave my email
open if you would like to respond directly, or email me your
number and I will give you a call. I am hesitant to write my
number here due to some of the inappropriate posts lately.
Thanks for your help.

David i think you will need wiring harness also. theres heavy wires in it for glowplugs. i will have to make sure but i think it had electric shut off. also i checked the decals and on the rearend just below where it says 403, it says diesel in letters about 10 inchs long. dont know if theres enough left to show up in a picture or not. serial # is 13513. i checked some of our other parts combines and the # run 4500 up into 16000. im not very sharp on the computer.but i dont understand how you mean to contact you. the PM says under construction. i dont blame you for not wanting to post your #

Hi Steve-
If you look to the bottom right of my post, you will see either reply,
or email. My email is open, meaning you should be able to click on
send email and ytmag will email me your message with your
address, and then I can email you my phone number.
Thanks
David
