Topic: t-case question

[sof'indetermined]

it all started when my t case started making some f'ed up noises so i pulled it out this morning. before i got too deep into it  a buddy found me another one cheap so cool ill just swap them and then i can do dual cases when i can afford it in the near future. my problem is the new case is different then the old. it came out of an 86 4runner. (both are top shift by the way) everything is the same except the shift fork ends where they come out of the front of the case are different. the new ones wont go into the tranny right. i thought i remember reading something somewhere that talked about grinding off the end or something to make it fit. is this a good idea?? or is there another way i should go about this. thanks in advance for any help.

you mean both cases  are forward shift

sounds like you have a G54  and a w56  the difference is  the length of the  shifter rods,  you can  swap the rods from the bad case into the good case

yea thats what i decided to do. i have the rods out of the old case i just need to now disasemble the new one. thanks for the help. so top shift are the remote ones right?? i dont know what they are each called.

where could i find another pair of shift rods for when i do dual cases. it seems like that would be something no auto parts stores would stock. am i doomed to having to get another case?

[79coyotefrg]

no, you'll have to convert  the rear case to a top shift

these are top shift



forward shift has one of these on the top

and the shift rods  come out the front  and go into the transmission

Marlin has a kit  that changes  the forward shift  toa top shift,  since  you MUST  use a top shift in the rear

i cant find the  "topshift kit"  on the website,  but i'll pm one of the guys

Wait Glen, he said they are both top shift, and he stated that one was from a 1986 4Runner (which IS top shifting), so I believe the discrepancy is that 2nd generation Top Shift forks (1985-88) are slightly longer and of a different design than 1st generation Top Shift forks (1979-83).

These differences are noted in our Gear Drive Transfer Case Bible:

Type 1-A,B,C all have a "Short Low Range Shift Rod"
Type 3 has a "Long Low Range Shift Rod"

Also, the 1st gen 2WD/4WD shift rods uses an inner C-clip to retain its movement, whereas the 2nd gen 2WD/4WD shift rods use an external "hook" that protrudes out the front of the reduction housing.

Type 1-A,B,C all have a "C-Clip Retained 2WD/4WD Rod"
Type 3 has a "Hook Retained 2WD/4WD Rod"

Therefore, I believe he is referring to this hook, which would interfere with his 1983 L50/52 transmission. If so, then he needs to either swap out the Type 3 rod for a Type 1 rod, or he may grind it off as long as he does not put excessive pressure forward on the t/case level while in 2WD high range.

We don't have a forward shift conversion kit, because its never needed except for very rare situations, but it could just as easily be offered. We have an overwhelming supply of forward shift parts in stock, especially the 1st gen forward shift rods (Type 2,4)

  how did i miss that     everybody knows 86 runner was efi  and efi was a  w56 a or b

yea  its already 104*  with a 112* heat index,  i aint goin outside

[sof'indetermined [OP]]

thanks a lot guys and i feel a lot better cause i was sure the ones i have are both called top shift and i got all screwed up but now im good again and yes its that hook deal that sticks out. i originally thought i could grind it down but a whole lot would have to come off to clear the tranny and i havent decided it if matters but that hook on the later model one keeps it from going all the way in whereas the older has a c clip on the fork. i havent pulled apart the newer one but it does not look like it has that c clip to keep it from going too far and its really not super difficult to pull the cases apart anyways its more a matter of finding the time now. i dont have a day off til thursday so i have to be patient and wait to put it back together.

   i thought it was hot here at 85 the other day. today was more like 70 which is still a little warm by my standards.

Yes, the new hook style replaces the c-clip style.

Depending on how you use your rig, you could run the rod without the hook (or an early rod without the clip) if you be careful not to apply pressure forward on the handle while in 2WD. Without the hook, if you shift into 2WD and then kick the shift handle forward over and over while driving down the road, then the fork will contact the #3 housing and may possibly become bound or jammed into the housing. On the shaft the shift hub will just run into the rear case bearing which would polish it down a bit.

So you can run it without the hook, just be careful when you shift into 2WD that you do not go past 2WD (far forward).

well i swapped them over it fit just fine. no weird issues or anything. i think it would be better just to use the ones that fit if your like me and you have them to use than to have to be careful about it. its really easy to pull the t case apart. i had no book or anything i just pulled it apart. easy. no problems
