@orangefj45 Twin Sticks, Hi/Lo Pops Into Neutral (1 Viewer)

[meatloaf]

So I took my 60 out for a ride after the NV4500 rebuild... I also rebuilt TC and installed Georg (@orangefj45) twin sticks and the hi/lo lever started popping into neutral, so I am having to slow down quite a bit or stop to push it back up. I get going and after a while it pops into neutral again. Could the threaded rod just need to be adjusted? or did I miss something when I rebuilt the TC?

Check installation of the hi/lo. Someone just had that issue locally and it was the twin sticks installed incorrectly.

Thanks @mattressking , what would I look for as far as incorrect installation?

Take a look at the small steel "block" that's now your H-N-L lever on top of the case. Make sure the angular cut is facing the right way. The "wider" portion should be at the front of the t-case, the "narrow" portion should be facing the rear.
I can post a pic later today if that helps.

Do you have pics of the setup before you installed it?

Take a look on this thread; first page, second post:

split case twin-stick kits!!!!!

I've been tinkering with this idea for quite some time now and have built a few prototypes. now I finally have a design that I'm happy with so i thought I'd start selling them. the kits come in two versions: 1) standard kit for single t-case setups. this kit is designed to be used with long and...

To rule out shifter linkage still applying pressure to the shift actuator on the transfer case, you could disconnect the linkage entirely at the transfer case and then take a test ride in 4 Lo to see if it still pops out. If it does, the problem is in the case, not the shifters.

@orangefj45 It looks like block is set correct

Thanks @OSS but that is what I was afraid of, I ran the truck in Lo for a few miles prior to switching to Hi and it hear did not pop out, once I went to the high gear it ran for about 3 miles with no issues and then it started popping up. I will re-run it in for low again when I get home from work. If it is the transfer case do I need to pull the whole thing out or just the back cover? What should I look for once I open the tc up?

On my transfer case when it used to jump out of Lo gear, the problem was the engagement teeth on the front output shaft and the corresponding notches in the hub sleeve. They had both rounded off a bit to prevent a secure engagement. I replaced them (in 1989) with new parts and it never jumped out of gear again. Also if the pocket bearing inside the rear output shaft that the front output shaft spins in is worn, it can cause the front output shaft to rock a little bit - causing it to lose grip on the hub sleeve. I repaced that too,

Jumping out of gear might be caused by something else too, but that is what was causing my problem.
Yes the transfer case has to be removed from the transmission entirely to replace the front output shaft
