fj62 t-case Vac to manual shift (the answer using all toyota parts)

lowtideride · 03-23-07, 08:02 PM

Well Im not at home so I can't give ya the part numbers but when I get thru the door I'll post them up.

Heres the deal, its almost too simple. You use 2 seals from an 85 fj60 case. Also the linkage from an fj60 case works as well. It even bolts right into the shaft its self and the only other thing left to do is make linkage for the hi-low shift...

Easy as Pie...

Pics are of both seals and linkage...

bump for 62 guys to see...

Can you provide a bit more information? This sounds interesting but I'm not "getting it" from the photos.

TIA!

lowtideride · 03-24-07, 10:22 AM

You take off the vac shift assembly and there will be a hole where the 2wd-4wd drive shaft comes out of. You slip the seal over the shaft and seat it in the "hole". Then you slip the booty over the shaft and pull it around the first seal just like on the 85 cases. You then can bolt up the stock linkage from an fj60 t-case.

Sweet, glad you finally took the time to figure it out. I knew it seemed rediculous to tear down the case to change it over. Nice work.

Thanks, now I get it. Well done, thanks for the explanation.

hell ya

cheap mod

Turtle60 · 03-24-07, 08:23 PM

Do you need the ball/bolt/detent thing to hold it in gear? I see where the hole that would hold the ball bearing detent to hold it in gear is not tapped. Does it click in and stay in gear without it? This sure would be a great improvement for my rig.

I'm pretty sure you need to add the detent ball .which also means you need to add the detents in the shaft itself. You do have to pull the case apart to do this properly.

Well Its been staying gear for me...ill report if it pops out of 4wd or not.

Lowtide,
Nice job bro!
Ive heard mention of this, but I havent talked to anyone who has done it.
So the x fer needs to come out of the rig to do this mod?
I like this idea...I see a lot of threads on the 4wd not engauging/ disengauging!

Thanks for sharing!

No need to take the t-case out for this at all. Unbolt the 4 bolts hold on the vac shift...install seals. bolt on linkage.....maybe 15 minutes..

My whole drivetrain were out of the rig for that picture

Winslow · 03-25-07, 10:40 PM

my 87 HJ60 is in the same boat, which a x-fer case like the 62. No vac. left. I've got the FJ60 lever, but have not tried it yet. I'm very excited. Crawling under the truck for 4wd kinda sucks, especially when its snowing! I look forward to part numbers for the seals.

greenfox · 03-25-07, 11:11 PM

I f remember correctly the 62 case has the detent ball in it.

DaveWest5150 · 03-26-07, 09:03 AM

guys, he's not changing to the 6o linkage rod, thats what you find when you take the vac. shift stuff off. in that case the 2/4wheel drive "switch" is acting like a detent.... not right, but it works

euclid · 03-27-07, 09:18 AM

Good tech. Thanks al.

FAQ'd

orangefj45 · 04-24-07, 09:37 AM

good info al!!!!

i'd definetly drill and tap the case for the detent setup. fwiw, the detent ball, spring and cap are the same as for the 2-4wd engagement. and they're fairly cheap from the dealer.

Good deal, More good info. Im planning on this around the bend ( when time permits)...

orangefj45 · 04-24-07, 09:43 AM

finding the proper tap might be more of a challenge but that's what the internet is for, ain't it?!

Does anyone know what the threads are on that bolt?

Will any year stock linkage work or just the later '85 and on?

I think 15mm x 1.5 based on further reading in FAQ:

You can obtain one of those taps here:

Hey Al when you did this mod, did the new xfer case shifter fit through the same hole in the hump? or did you have to cut it a bit??

also did it pop out of gear ever without the detent ball and cap??

and what are the part numbers??

thanks

tonkota · 07-14-08, 11:12 AM

In the first picture, you have a manual trans so

for that

. I still have the autobox. Is there a mounting boss for the linkage on the automatic?

Oh, and great job and thanks for the information. :thumbsup:

orangefj45 · 07-14-08, 10:19 PM

modifying/changing the high-low lever in the vehicle would be a pita but can be done.
i'm about to do a swap like this and can post some more pics and info if anybody needs it.

thanks again for posting this. it's what boards like thie one should be all about!

I hate to be the bearer of bad news but that won't work.

Here's why it won't work.

1 The vac transfer shaft is way shorter than the manual transfer shaft and this puts your whole 4wd stick and linkage on totally the wrong angle. It will sit way too far forward at the stick.

2 The Hi-Lo lever is in totally the wrong position on the vac transfer and will never work unless modified. And you cannot just fit a man transfer lever as the flat on the shaft is in the wrong place.

3 The vac transfer has no detent to hold 2wd or 4wd.
You MUST have a detent or you will have an unsafe system.

There are a couple of other mods that need doing as well to get the thing working right.

I've done this modification without going inside the transfer, and I can tell you it took a lot more than just throwing in a seal, bolting on all the manual shift mechanism and off you go!

why don't you elaborate some then?! coming on here and critizising the original post without supporting your statement with details does'nt help anybody out.........

Bomar · 07-15-08, 08:58 AM

GM60

Tell us how it is done. I will tell you lowtideride has done alot of great work on some rigs.

lowtideride · 07-15-08, 09:04 AM

Jesus,

re-read the first post in this thread before ranting.

I said it as clear as day. You can use the linkage for the 2-4 but you have to make new linkage for hi-low. The t-case shifter linkage I used bolted right up, there was no problem there so I don't know why you had such a hard time, maybe a different year linkage.

Again, this has been covered above that use of a detent ball is a good idea. So why are you still harping over it.

Wonder why I never come on here anymore.
