Gots me a half ton travelall with 44's front and rear. Well, its so rusty that the rust outline resembles a travelall. My 800 is running 196,T-18,twin stick D20, stock axles F/R.

I'm thinking spring over with the 44's, high steer, mini spools F/R, power steering. (yes I have the 196 power steering bracket) The only trade off I can think of is going from 4.27's to 3.73's. I dont think I'll make enough HP to bust a 44 shaft, yet. Anything else I should think about, consider, forget?

Don't forget to swap the motor while you're working on it:flipoff2:

The t-18 wont fit anything but a 152. I have the twisted bellhousing thats really short. Early 196's had that 15* lean to one side.

The T-all has a 727 with the divorced 205. I really pride myself on staying all IH. Couple of the NW binders guys can back me up on that one. My 73 scout II with full size IH junk under it, works well and looks good too. Not that it matters or anything.:rolleyes:

T-18 WILL fit the 196!!! Even if you get a 196 out of a SII it is an easy fix to make up for the slant---small wedge under carb. If it doesn't I have no idea what 4 speed I took out beofre I put in the "short-shaft" T-19. As long as it is a short shaft T-18 it will fit behind the 196---unless you moved the motor forward to V-8 position whereas you can use any tranny you want due to the extra room between motor and firewall.
Why go mini-spools---just go with full spools(stronger)

Get the PS box out of a 78/79 Ford F250/350 2 WD truck---fits in the place of the stock manual box with minor mods. That box with a boosted SII pump easily turns 38's with one finger on pavement. The PS bracket isn't going to do you much good. The space under the hood varies greatly between the SII, where the bracket came from, and your 800. I just used the SII PS bracket as a base to build off of.

Depending on the tires you use you will need to do a R&P change. With 3.73's your final crawl ratio will be 29.84:1 and that is not taking into consideration tires over 33" tall. With your 196 you will want a final crawl of AT LEAST 70:1---trust me!!! I love the 196 and that seems to be the magic number--anything less just won't do.

It has a 196 already, like my first post said:flipoff2: The ONLY other engine I would consider the tranny fitting is the weak 152. I think I can use the scout II pump bracket with a little work.

I like mini spools cuz I can install them in under an hour per locker, thier cheap, and they work.

My crawl ratio would be 6.1x2.03x3.73=46.18. Roughly

You need gears, or a supply of new clutches. My auto is at 36.5 with the 3.73's will be 44.6 when I go to 4.56

Are you using a T-18 out of a Ford cause there ain't no T-18 short shaft IH tranny with a 1st gear of 6.1:1. More like 4.02:1 for a short shaft T-18. Unless you converted an IH truck 2wd T-18 to 4wd and swapped in the short shaft which I don't think is possible.
Like I said 29:1

You need gears dan, the 196 even more. Close ratio t-18, and just a D20 does not make a good wheeling combo, even with a V-8 with crappy gears.

ever wonder why they put 4.27's in a 26" tired 80/800 with the 4-banger???

what tires you plan on putt'n on this thing?

35's in the end, with some trimming.

I have a 63 scout 80 with the t-90 (3.33 1st) ,D18 t-case (2.43 low), 4.27 axle gears. My 800 is WAY slower in 1st/low than my 80. Just an observation. Maybe the 196 idles slower.

I dont think your entirely correct about the 18's either. The throw into first gear is very long. The shifter misses the dash by about 2 inches in 1st. Close ratio 18's first gear is 'closer' to the rest of the pattern. The thing about IH's, they came in so many variations you cant be positive about anything.;) Also, I didnt buy this rig new and I dont have the line setting ticket so anything is possible. It could be a t-18 with t-98 guts for all I know.

I can be very positive about IH T-18's in 800's. A lot of variations is true but not with motor/ tranny combos. A 196 in an 800 either CAME WITH a T-90 or a T-18---if it has 4 forward gears it is a T-18. Stock SII T-18's or T-19's will not fit--no way no how, assuming the motor is in its stock placement and you still have that 12'' space behind the grill until the radiator bulkhead starts.

Whatever you do you will not be able to run 35's with 3.73 gears and that driveline!!!!! I run 196's exclusively and love them when properly geared down---otherwise they are piss poor and a joke. A friend ran 33's with a 196, T-18, D20 and 4.56 and he is desperately trying to lower his crawl.

Don't believe swapping in T-98 guts works--maybe swapping in Ford T-18 wide gears.


Figure out what you have, pull your head out and gear it right the first time---or don't , get pissed about the low power of a 196, swap in a V-8 and sell me the 4 banger.

I love not having any power. Thats the whole love affair with IH's. I'v been running a worn out 152/t-90/spicer18/4.27's and 31's for a while now and have gotton used to the second gear down shift at the slightest incline.

Like I said before, I'm an IH purist. I'm not gonna run ford guts. Do they make 7.17's for Dana 44's? If I wanted that much more gearing I'd put spicer 18 gears in the 20 or mount a 205 from a travelall or PU behind the T-case or both or maybe a klune or a mr. scout box.

Maybe I'll find a way to mount 2 T18's together, a couple of Spicer 18's and some IH corporates that came from a duece and a half:flipoff2: Then I'll run some 28" boggers and go even slower. :flipoff2: :D Good times

Also, I was under the impression that T-18's and T- 98's were the same tranny except for the output and gearing variations. The shifters and top covers are the same anyway. :goofball:
