Hey.

I am new to IH's and I have a question about an IH pickup I found. From what info I was able to gather by looking at it and by looking on the Net, it's a '66 D1200. Does that make sense?

It is 8-lug, and I think 3/4 ton. Looks like Dana 44 front, and I think it should be Dana 60 rear, but instead it looks like a GM 14-bolt. Any guess what gears it could have?

It also has the 345 engine, and has a PTO winch on the front. This thing has been sitting for at least two years (that's the first time I saw it) but does not have much rust, so I thought I might try to pick it up.

It is a 4-speed manual. Any idea what trans that might be? What about the T-case?

Thanks!!!
Richard

if its a 66 it would be a C-series. More rounded look and round taillights.
D-series started in 69, square look and square gauges in the dash.

would be a T-98 Tranny.

Gears are anybodies guess, even more so w/ a GM 14.
Sure its not a IH corprate???

If it's a "round" 1966, then it shouldn't have 8-lug axles. 5 on 5.5 1/2T, or 6-lug BUDD for the 3/4T.

If it has 8-lug axles, then it could very well be a Chevy '44 and 14-bolt.. or who knows what. Could be as simple as axles swapped from a 69-75 IH..

Trans should be a T98 wide-ratio non-sync 1st with R being right and forward.

T'case could be a NP201 or NP202.. I don't know just when they phased in the NP205. They're all divorced.

Go back a little earlier and you could end up with a Rockwell divorced 'case, too.

This truck is definitely round. I read in the door jamb (I think, it has been a while) that it was a '66.

It is also definitely 8-lug, so maybe someone swapped in some axles.

About the T-98 trans - is first gear a granny gear? Do you know the ratio?

About the T-case, I know NP205, but I have no experience with NP201 or 202. What are they like? Comparable to NP205?

Thanks again!!!

NP201 or NP202 are the grandaddys of the NP205.

The NP205 was the cheapened weaker offspring.

:D :D :D

SWEET! That's what I like to hear!

If I can get this truck, I'm sure you guys will be hearing more from me in the future.

Thanks for the info!
Richard

There is some miss info hear a 66 D1200 is correct 69 would be 1200D (notice the move of the letter and both are 3/4) would be a NP 202, stronger then the 205. The 202 has a low of 1.925-1. The tranny would be the T-98 with 1st of 6.398.

If it has the stock axels it should be a HD 44 up front and a 60 in the back and it also should have a 6-bolt pattern witch is unique to IH and the drums are very hard to find. I head they were available from Napa but that was a while back and they were expensive but from the sounds of somebody converted to 8 lug pattern you can convert to disk from parts from other trucks or you can find a 74/75 IH truck and directly swap (strait bolt in) axels for the disk brakes.
The IH SV motors (266,304,345,392) are built way different from ford/gmc these motors were designed for dump truck and they moved tones of weight from the get go. If you look, the 345 has more torque at lower RPMs than a Chevy 350 or ford 351 and dodge what ever. They have no timing chine it is direct gear and remember to time off no 8
Max RPM is about 3800 but I have heard about tacking it to 4000 with no problems.
At 4400 RPM the valves float. With these motors you don’t need to mash it just depress it a little more. Fell free to ask any more questions

good luck with the beast

Thank you!!!
