So you really need to know the thread pitch of the end that s in the case already.
This ^^^^ a regular bolt won't work, I guess I should say it's not a regular bolt, it might work if you buy the proper thread for the t case side and have enough room to feed it thru the trans and into the case. IIRC there were a few of the nuts that were tight to get to, so i'm not sure feeding a bolt thru would be any fun. I sent you a pm.

+1

On my 1995 YJ, they are 3/8-16 on the end that goes into the transfer case and 3/8-24 on the nut end. Use loctite when reassembling these.

I doubt you will be able to find these at your hardware store. Try a Jeep Parts dealer or online.

Here's a picture showing the double nut technique that you will need for the studs.

You would need to swap in your electronic speedo gear and sender from your old tcase. You need the sender housing that the plug goes into, as well as the speedo gear. You will also need to make sure you "clock" the speedo gear correctly depending on how many teeth it has.

http://www.jeepforum.com/forum/f9/cl...sensor-428357/

The above link is for a TJ, but the principal is the same. Find the range on the sender housing that correlates with how many teeth the speedo you are using has... Make sure that range is pointing down, or 6'oclock upon installing, otherwise your spedometer will not work.

The length of the gear isn't specific to the transfercase, it is specific to the type of speed sensor "housign" you have... My stock YJ speedo housing was about 1.5 to 2" longer than the one that was normally used on later model electronic speedo YJ's... I had to pick up a new speedo gear "housing" from a local jeep shop used. The original housing used a very long speedo gear, the new one used a much shorter speedo gear. The color only designates how many teeth it has, but you can manually count them.

Why cant you use the speedo "housing" and gear that you were using before? The differences in speedo length are an issue with respect to the part the plug goes into more than the transfercase...

I'm at work at the moment, I apologise. Here is a writeup on how to post pictures. This option is free:

http://www.jeepforum.com/forum/f22/h...pforum-658070/

Otherwise I'll try to email you when I get home.

I'm not sure I am understanding your issue though. There are 3 parts associated w/the sending of speed to your spedometer.

1. The housing that the gauge plugs into,
2. The speedo gear...
3. The wire/plug or cable/wire/plug depending on whether you have electric/mechanical hybrid, or all electrical.

Does your jeep use the cable/electronic hybrid? Or all electrical?

If all electrical, then you have to use the "housing" from an all electric setup, the speedo between the two types of housings will interchange if the housings both require speedos of the same length. Why can't you just use the one that was on your busted transfercase?

As for the difference in lengths, some part #1's and Part #2's listed above were longer than others. The issue is with part #1 as to which gear is correct. If the part #1 you are wanting to use houses the longer speedo, you need the longer speedo, likewise, if you have the shorter housing, you need to use the shorter speedo....


All of the housings described above, will fit an NP231 case... So in essense, you should just be able to swap over the speedo housing, and gear, from your original transfercase, onto the new case.
