T/case and stuff (newbie question :-)


out of the lurking mode here I come :-)
Is there an easy way to recognize a '84 t/case?? Something unique like eg. mounts/hole[s], etc...???
If they are of identical shape to the later models, I guesss I could count the IN/OUT ratio. What that number would be for a '84 and older?? For '85 and younger?? I think I should do the counting in the LO range, since the difference would be more apparent, correct me if I'm wrong.

Are the '84 driveshafts identical to the later ones?

Are the '84 axles identical ot the later ones???

You guys are great, I've learned a lot from this board :-)

Re: T/case and stuff (newbie question :-)

Well I can helps with some of the ID, First off they will have a t-case emergancy brake drum off the back driveshaft,
the flanges will be smaller than a later one, the driveshafts are smaller diameter. I don't know the ratios.
But both hi and low are 12% lower than a later case.
The axles are also smaller, and the gears are lower but cannot be used in the later chunks. Hope this helps.

The alxes on my parts SJ410 are solid steel. They look like driveshafts. I've been thinking about using them on the Sami....one day...

Drive shafts and diffs are different. The drive shafts are small, thin solid shafts, with smaller flanges. The axles are smaller, narrow, and have 4.10:1 gearing.

All Identical.

84 T-case has the following:

4WD light switch on case(next to shifter)+drum brake+ 2.53 ratio in low 4WD.

Turn input flange 1 turn and the outputs will turn 2.5 times!
If it does you have an 84.

If it doesn't have the 4WD switch it's and 82-83.

If it doesn't have the 2.5 turns, it's just a plain old 86 and up.....

Pictures of an 84 are here http://cszukisite.homestead.com/tcase.html

(note the 4wd light switch)

As a passing note I have an 83 which also has 2.53 low but CANNOT be made into a GRS1. It is selling for $150USD+shipping(45 lbs).
