I am going to be replacing my t-case with one that someone on here is selling to me. My exsisting is an 87, im not sure of the year on the one I am getting. Are there any differences between the 2 or will this work fine with any year fj60? If there are differences, what can I do to correct them and make it work? Thanks for any help.

Why not rebuild the '87 ?
Answer to Q: Yes, there could be differences. The easiest is to ensure the T'case you're getting is a 5/85 - 7/87 .... around 6/86 IIRC, they switched to a 38mm idler shaft, vs a 34mm for the earlier. The 5/85 to '87 will bolt up, though.
4/85 and earlier may have other differences, but since you have the long bolts (into tranny, through t'case) you could probably use an earlier one, but I can't remember if that's the ONLY difference.
Again, the best thing to do would be to rebuild your '87, if it's re-buildable. It's not too difficult, and you got to take it apart to get it off so why not ?

I was going to rebuild, but a member on here that is a couple hours away from me has one that is complete and in good condition and he is selling to me for 100.00. Kind of hard to spend double that to rebuild mine. I have said this before but I will ask again. Why does the t case need to be torn down to replace. Do you have to open it in order to bolt it to the trans, then put other half back on, then bolt together?

Yes-basically the only way to reach some of the bolts holding the two together is to split the case. You'll understand immediately once you dig into it.
That's why a case rebuild is not big deal-you end up doing all the work anyway!
Check the bearings carefully on the new case and replace any that are suspect. Also check carefully for wear on the input shaft(tranny output shaft).

Is there any way to tell what year t case he has with out having to open it up?
Cruiserdrew
On the way there
Not exactly, but you can tell if it's pre 4/86 or after by the size of the idler shaft sticking out the back!
34mm = Pre 4/86
38mm = 4/86+
If it has a 38mm shaft and a vacuum 4WD shifter its from an FJ62.

Do you agree that they are still interchangeble? It would seem so. Are the output shafts splined the same, and the trans hookup the same?
even if you buy a used case, you will have to take it apart to install it.....
It will not bolt on to your trans w/o being taken apart.
I'd rebuild what is already there.

Just rebuild yours.
1. you know what you have will work.
2. You got to COMPLETELY disassemble the case to remove and reattach.
3. You always need to have a #3
Just rebuild yours other peoples stuff always sucks anyway!

Not to be a pedant about this, but I've noticed a bunch of threads where you ask the question - get an answer, then ask the same question 3 more different ways...
It would help you greatly, if you don't already have the FSM, to simply download it and read the relevant sections first, then ask questions.
It will make the answers much clearer to you and your questions more precise.
I'm just sayin...

If your tranny has the spacer on the back of the gearbox the older t-case's will not fit. If the t-case is bolted direct to the tranny (no spacer) its the older style. The first pic is my older t-case bolted to a 4 speed and the other one with half the newer style transfer case is my H55 with the spacer.
One thing I found as I combined parts for my 5 speed install, the main transfer gear has the same splines older or newer but the gear teeth from an older case is a different size that will not fit a new case.
The seal surface between the gearbox and t-case is part of the tranfer gear on a newer style case and on older cases it's a seperate piece from the gear.
If the used t-case is off the tranny, take a pic of the side that bolts to the tranny and I or someone else can tell you if its the older style that may or may not fit your 87.

Here are 2 pics of the one I will hopefuly be buying. I know a lot of people are telling me to just rebuild mine but it really is not worth it at this point. The front output shaft is broken and all output shaft bearings destroyed, so not only would I need a rebuild kit, I would need a new output shaft. Then I would have to take the case to a machine shop to have the bearings pressed. Now we are looking at a half day gone. For 100 bucks I dont think I will beat this deal (if it works). As far as posting this question several times, I havent posted this before. I guess having two post about t-cases means I'm asking the same question. this post really is to see what the differences are between the cases and how to identify the differences between different year cases.

That case has an extra adapter plate on the front of it.
I can't tell for sure, but the case for sale is at least an 84. In 83 and down, the output flanges were square, then in 84 went to round.
I'd be very curious about the adapter plate. Did the case have a Marlin box in front of it at one time? Do you know it's history?
What ever case you use, you should rebuild. That way you know the condition. You may go to all the work of a tear down and swap, only to find it has whiney bearings or is also in need of service.
Looking past that unusual "adapter/spacer" it looks like it is the newer style case. It has the deeper recess for the bearing on the input shaft. Would need to see it without that plate to be absolutely certain. Does your tranny have the factory 3 1/2" spacer on the back of it?
I don't know if you could trust the size of the flange as a date indicator considering that plate thats on it. Flanges are easily switched. But take Cruiserdrews advice to heart and rebuild it now. Not hard to do and the case is already apart for the install. Your halfway there.
FJ40jim mentions date stamps but my 1982 case has a number that is not a date and my 1988 case has the date written in a really odd way "8 H 88 2"

thanks for your help. i will see if he can send me a pic without that plate. I will def rebuild it before puting it in. I just really want to be sure that it will bolt up.

The standard Toyota date system on engines, carbs, fuel pumps, cylinder heads, etc is: Y M DD.
For some reason ASCO doesnt use the standard format.
They number the T-cases: Y M serial.
So a 8 H is a 1988 August, 882nd case built that month.
There should be a sticky for this info.
