So like an idiot I tore down both transfer cases and a th350 at the same time

I found this in a bucket where I had dropped it while moving some parts. The bucket was clean at the beginning so I know it was recently dropped.

1/2” thick
About 1.4590” max outer diameter
0.9600 or 0.9595 ID

The outside is radiused and there is a slight wear line on one part of the outside

It does not appear to fit any NP205 shafts

It does not appear to fit any TH350 shafts.

Np203 shifter bushing? The 203
Is back together so I hate to start tearing it apart immediately.

I've stared at your pics several times but can't figure out what it is. The rounded outer surface is the confusing part for me, is there a chance that's the inner piece of a heim joint or something that coincidentally ended up mixed in.
 
Get it all back in and truck and drive around and see what breaks :rotfl:

I have no real value to add. Not sure what it could be, but based on wear line, would think that its inside a case somewhere

@tarussell any thoughts?

Damn, I don’t know ?
Could be a non original part used as a spacer in the 203 case but I can’t think of a shaft that small of diameter where it could have been used.

Was the 203 a full case when you took it apart or just the range box ?

As KTMOUTFRONT and NVRENUF and others have said I’m certain that part is not from the internals of a 203-RB , 205 or TH350 - been inside more of each of them than I can ever recall and there just ain’t no room for anything like that. It does look like the inside piece of a hiem joint though.

I found a bigger piece today, this is getting concerning. Re-assembly used to be one of my finer points.

I dry fit the 205 today and i don't have any slack in weird places, except maybe the idler, but it has all the pieces, probably needs another shim.

The 203 spins well and shifts ok. With the 205 in one piece, i can move it around now at least. I'm going to make some room so I can clean the 350 and inventory it. At least there I can match everything up to a Precision Transmission video.
 
Does the new piece seem like it’s related to or a part of the original piece?

Could possibly be part # 104 in the illustration.

Can’t be part-104 in the illustration - that shaft is larger than the I.D. of his mystery piece and it’s on the output shaft of the 203 and he’s only had the low range box portion torn down amongst all what has been worked on at this point.
I thought about that part as well until I considered the I.D. & O.D. of the related components and the whole case was not involved.
Also, part-104 should be one of the drive sleeves.

Mystery pieces search continues….



Any pics of the second larger piece ?

This was awesome. I had the 205 ready to go, and pulled the covers to put in gaskets, sealed it up, and now the input and rear output are locked up.
front was fine, minus locking up when it was in gear. So, somethings kinda wrong.
 
This is gonna call for several pictures upon disassembly.

This does not explain the foreign parts (that don’t belong in any of your cases) but as far as the input/output shafts binding up , could you have mis-installed a shift fork/collar ?
 
So it was good, then you pulled covers to put gaskets in and it locked up? Or it may have been locked up prior to the cover pull? Seems odd that just installing gaskets locked it up
