Np208

Does an NP 208 seal itself or do i need to make one to go between the adapter and the tcase. I know its a stupid question but i just want to make sure.

alright. Thank you.

I also have anther question. There seems to be a breather hole on top of the case. The one that was behind my 700r4 has a metal tube coming out of it but my 32 spline dosent. Could i tap the hole and then fit it with a nipple that i can add a longer breather tube to it?

Are you talking about the hole in the top of the tail housing? If so I don't see why you couldn't tap it and and run a hose from the fitting.

Yes i was. When i was at the parts store i was like what the hell and tried it anyway. Worked out good. I got everything back together tonight only to find out that the front output is leaking, but thats an easy fix.

Jimmy Ho just gettin started
same thing happened on mine... turned out to be a bad shift fork in the 'case...not too hard to fix, but i'd do it before driving around too much... it would always pop out at the worst possible time until it eventually wouldn't go back into gear.

Most np208's had nylon buttons on the shift forks, these will wear/disintegrate, leaving you less than completly in the selected gear.



This one may be more legible -



You can get a replacement fork from BJ's offroad for about $40.

Before you go and tear into the case, there are several things you need to check first.

1. Make sure that the shifter linkage is adjusted properly. To do this, put the shifter in 4HI. Then put the t-case in 4 HI. You should be able to change gears by hand. The t-case shift arm all the way forward is 2HI. Move it back one to 4 HI. Loosen the retaining nuts at the cab selector, make sure that the arm is not bound up, then tighten down the nuts again. Also, you want to make sure that the shift link rod is not bent.



2. On the side of the case you will find a bolt head. It's located near the shifter arm. This is the shift lever detent. They are notorious for getting packed up with goo/mud, having a broken spring, or being rounded off. Remove the retaining bolt, pull the spring, and the detent should come out with it. Check for wear and/or crap. Use a lil brake cleaner to tidy it up. Replace any broken/worn parts. Reinstall.



As for the seals, they may leak a lil in the beginning until the seal material swells a bit. Make sure you check the rubber star seals that go around the output shafts right behind the retaining nuts. If no leaks, don't upset them.

When you bolt up the t-case to the adapter, use a good amount of RTV. Paper gaskets aren't even good enough to wipe your butt in this application. RTV is your friend. A healthy bead on the outer and inner edges of the adapter and you'll be good to go.

Hope this helps.

Manny

How hard is to change the shift forks out?

Or would it be easier to change out the output?

Can i use shift forks from a tcase i know is good?

That requires taking the t-case apart. You have to split the case halves, lift the assembly partially out of the case, remove the shift forks, inspect, replace the plastics if necessary, then reassemble. Not a big deal, just a lil time consuming. Like I said before, you should check the other things before you go there.

BB, google "241 slip yoke eliminator" and you will see a few vendors who sell a SYE for the 241 have 'how-to' articles on taking the t-case apart. The 241 is very similar to the 208 and the articles will give you a good idea of what is involved with dissassembly.

It's a pretty easy fix. There are little nylon bushings that go on the end of the fork. The last time I did it, I bought the bushings from the Chevy house. You can do it while it's in the truck, but would be easier if you had it out and weren't laying on your back under the truck.

I don't remember the cost, it's been four or five years since I had to replace them. I know it wasn't much though. I can't confirm they are the same as a 241.

zukidave will become famous soon enough
I'd suggest if it's the first time you've opened
a t-case then do it on the bench not in the truck.
for me it's easer to do them in the truck but then
I've done a bunch of sye's

Yeah im not going to try and do it in the truck. I have to pull the case anyway because i took a gamble on seal between the adapter and transmission and lost so its going to have to come out anyway. Thanks for the tips guys.
