Chevy NP246 Transfer Case OT Question

Hi All -

I put a set of seals in the transfer case from my 2006 Chevy Suburban - and I can't remember what the story is on these collars sticking out on two of the bolt holes that hold the two halves of the transfer case together. There is one on each opposing end of the transfer case.

Did I mess around and let them slide out slightly while it was apart? Or do they take a special bolt or set of washers?? The other 10-12 bolts just snug up like normal.

From most of the info I can find on the internet, it seems like most/many of these transfer cases just have regular bolts at these locations, so I am puzzled as to why this one has that collar protruding out.


Thanks for any advice,
Howard

That is probably a locating ring that needs to be in (flush) to place the cover concentric with the housing. The remaining bolts do not position the cover because their holes are clearance holes. (this is a guess from many other assemblies, not that transfer case) Jim
 
It's been a while since I've worked on those, but as I recall they are simply hollow alignment dowels.

I would try to carefully tap them into place before tightening the other bolts.

HOPEFULLY will go back in place without chewing into the edge of the hole.
 
Yes - thanks a lot, fellows! You were right. They were alignment bushings that slipped out.

I just didn't want to mess something up going back with this.


Thanks a lot,
Howard
