Are you going to use the New T'case you got ? The different size idler is fine, if that's what you're worried about.

Just inspect the bearings/components as you reassemble. If you don't want to buy gaskets, reuse the old gaskets and smear liberally with gray or orange permatex RTV.

If you find a suspect bearing, you can buy individually. The numbers on the bearing are standardized, so you can take it to a local store. Don't buy a Chinese bearing, if you need one - buy Japanese or American. Timkens will be a good value.

Since you never said what was the problem with your original t'case, or if the new one is ready to use, I can't really be much more help than that.

my concern was that the case i bought would not work due to being one from the earlier years. someone had said something about gear teeth not being the same. My case has a broken front output shaft and all the front bearings are gone. The one i bought seems to be in great shape other than its a pre 85 and it might not work. I am really hoping it can just bolt right up. Thats really all im trying to find out, is if a case from an 83 can bolt up to an 87. one member didnt think so. Sorry for poor grammar. Writing this on my phone at work.

If anyone has an idea as to how i can make this work please let me know. I really need to make what i have work without buying a 300 dollar rebuild kit.

Not even new gaskets?

This is a lot of work to go through to save a few $$$.

At least consider replacing the idler shaft and it's o-rings and bearings, and look very carefully at the output shaft bearings as well. Rebuild kits are typically in the $200 range from Mudrak or Cruiseroutfitters.

Do things once correctly or plan on doing them twice.

I agree with Andrew, but if you don't have the $, you don't have it. If you inspect components and they look good, chances are it will work for many years. You may get some leaks and perhaps some noise, but it'll go...

The earlier T'case should work. You will have to use the long bolts from your '87 t'case to bolt the new t'case to the tranny. You will not be able to mix and match gears or bearings between the two cases.

Don't know why that adapter plate is there, but start the process and take pix and post if you get stuck. You may want to post some pix of the tcase after you remove the adapter to see if there's been any mods to it.

Incidentally, the front output shaft for your '87 t'case is around $200 for Japanese aftermarket ( I had to buy one ) and a rebuild it is around $200, so with shipping you're prolly looking at around $450 shipped for parts for your '87 case -- that's if nothing else is junk.

Holy smokes! That bolt is a pain to get off'. I still have not gotten the bolt off that is on my exsisting t-case. I had a 4 ft breaker bar and was actually moving the motor, and the bolt will not budge. I guess I will have to put some heat to it tomorrow. Anyways, here are a couple pics of the case I am trying to use. You can see the mounting plate that was on there as well.

 

[Spike Strip]

At the very least, you're gonna want to put a new seal here.

That Nut on the output shaft is staked, so you'll have to pry up the stake notches and hold the flange with something. You can make a SST by using a some flat stock and drilling holes to fit over the studs.

 

[Spike Strip]

That case looks fine, too, btw... Wadda the guts look like ?

The front half of that case looks to be the correct one for your tranny (4 speed with a spacer). Regardless of the idler size where the bearing on your tranny output shaft enters the tcase it looks to be correct. Also that small recess below the opening is actually for a small funnel associated with 5 speeds. You won't find it on early tcase's. What you may find on your old one is a hole for a bolt (right about where that arrow is) This bolt has been eliminated on 5speed and auto tcase's.

Check to make sure someone didn't mix and match on you. Make sure the idler shaft holes are the same size in both halves of the "new to you" tcase.

About that nut. Make yourself a plate that bolts to the flange. Unstake the nut (tap a small chisel into the notches to spread that part of the nut that has been pounded in) Put your wrench on the nut, make sure the plate is jammed against some thing and smack the wrench with a dead blow mallet. The nut will come right off. It is only torqued to about 94 ft lbs (Toyota specs) By the way you will need the plate/tool to re assemble the tcase it will also work on your differential flanges.

I sent you a message with my email and ph#

Thank you Spike and KYnot. Igot that little piece bent up and will see what I can build to hold that flange still and get the bolt off tonight. I cant tell you what a relief it is to hear that this case should work. Spike, thanks for the heads up on getting a seal for that opening. I am going to order a complete gasket set, so I will add a seal to the shopping cart. The internals look great. Everything really seems to be in very good shape.

 

[csd4682]

I forgot to ask. Does anyone have a clue as to what that plate was for?

 

[Spike Strip]

An adapter plate to bolt it up to a different transmission.

To what I wonder, that would have a 19 spline output.

You better check the number of splines on the input and make sure the splines are correct. Who knows what sort of a frankencase that is. Where did it come from?

Does that front output shaft not look right to you? How many splines should it have?

 

[Spike Strip]

So how you coming with it?

 

[csd4682]

Got the old one completly off late last night. Everything looks like it will line up just fine. The only thing that gave me a scare, was the case I bought didnt have the pto gear. I did a little research on SOR, and that is actually the only gear in the t-case that is interchangable between years. What a relief, I can just use the one I have. There is one hole in the front of the case that I do not have on my new one. Kynot had mentioned that it may have that. Im not sure what needs to be done about not having it. I am ordering all new gaskets and seals tomorrow morning. I am siked that everything is looking like it will work. Thank you guys for all the great info. I will keep everyone posted.

 

[Spike Strip]

That hole would normally take another bolt into a 'brige' across the middle of the 'spacer'...

When you go H55, you block off that hole in the t'case shell ... Don't remember if it's a blind hole or into the case itself...

Anyone ?

You have to block off that one hole. I used a plumbing plug and locktite. I posted pics way back when.

 

[Spike Strip]

Drew, he's asking the opposite: He's got a case without the hole, but the 4 spd/ spacer with that extra bolt hole in the spacer... What happens if he just leaves it out?

Missed that. It should be fine, but I don't actually know.

Thanks for the correction.

I would think that not having the bolt will not have any effect. The fact that the H55 and the auto tranny both eliminate that bolt would indicate that the bolt is not that critical. I would think that the spacer on a 4 speed is pretty much the same as the spacer around my 5th gear, the difference being that web.

And that bolt is not present on early tcases either as a bolt would run into the bearings on a non spacer tranny.

About that pto gear, if the tcase has a longer spacer you do not have to use it. When I tore down my diesel tcase, I found that it did not have a pto gear. The gear was replaced with a longer spacer (by Toyota, not an afterthought). But remember you can't just remove the pto gear you have to use the longer spacer that will account for the gap left by having no gear.

I will just use the gear rather than trying to find a spacer. It is the same part used from 1980-1990 according to SOR.
So if there is no bolt going into the tranny due to not having that hole, you dont think that it will cause any leaking issues
