I know this is an old thread, but I am thinking of changing out my stock 76 transfer case with T-case saver to a 83 FJ60 split case.
I am running a NV4500 with a Advance Adapter.
What all do I need to consider?
Would the input splines to both cases be the same?
Would the split case bolt up to my Advance Adapter?
Would I need a longer rear drive shaft since I no longer would have the parking brake drum?
Would this swap be worth it?
Thanks for your help!!
Lots of considerations, Poser hit the nail on the head for some of the major ones.
Input splines go from 16 spline to 19 spline.
Split Tcase should bolt up (other than the spline differences.
You can get the Pbrake drum for the split tcase, I believe that George ( @orangefj45 ) has some right now. But you should assume there is going to be a length change.
Split tcases are very strong and quiet. I would much rather run one than a one piece case.
I frankly, don't get it. Your 3 speed transfer case I assume is working just fine so why do you want to complicate things by swapping out to a split case? You'll loose your parking brake and the low range in the split case is not quite as good as what you have now. Yes, it'll be a strength upgrade but your current case will last just fine if you brace it across the top and also the front output. The split case seems like an incredible amount of screwing around for very little end benefit, IMO
