I tore my transfer case apart today thinking I had a broken chain or shift fork problems and I found this (see pics) I am not sure where this steel rod is meant to be and I dont know how it broke but it did in 4 places! I also have a bunch of broken roller bearings and washers. where the crap did this thing go and what is it

any idea what part that is according to that diagram, thanks for that by the way.

it looks like the shift rod #71 but its not, this is smaller in diameter

if it helps anybody this case has the dodge rear half SYE done by the PO I dont see where this rod is apart of that but just throwing it out there.
 
Not sure about the rod but those bearings are PC 22. Not sure if you can get them in a rebuild kit or not. There should be 62 IIRC two rows of 31. I helped my brother rebuild his fixed yoke 208 and the only rod was for the shift forks and I can clearly see yours in the picture.:dunno: This is def a puzzling one:thinking:.

if you look in the first picture that I posted you can see the shift rod still in place before I disassembled it, also the broken rod in question is sitting to the right of the case.

I did see from that diagram that my annulis(sp) has some problems it came out in pieces and has some cracks

That is what the rods are. They are the shafts for the planetaries that ride in that shell with the sun gear in the middle. It gives you your reduction in Low.

PC-11 should be one assembly with the planetaries sandwitched between those 2 plates. You can see that yours is apart and I can see the gears in the background. I guess when you put it in low it moved the sunshell enough to let those shafts out and off the gears. That is the only way I can see them getting out and into the case:confused:.

Wheres Marv , he has a box full of pieces on his patio . Maybe he can shed some light on it .

To be honest its been since 2004 when mine was apart for the input swap .
 
doh
I should have realized that they were all the same length and broke the sameway. its 4 seperate rods not one rod broke 4 times.
I knew something was not right with the planatery set. but it has been so long since I had one apart. you guys are awesome thanks
 
To my knowledge the planetary is the week link in the 208. I would suggest swapping it out with a 241 but you already have an SYE so it would only net you 2 more planetaries over the 208.

I wonder if it has something to do with his 350 TBI , and sm465 ?

The automatic guys in AZ aren't shattering those . And Marv has a 208 feeding another 208 .

I was just saying that with everything in the 208 the planetary is the weakest part. For some reason that sticks in my head from on here. I beat on mine pretty good and have broke a front driveshaft and have not hurt the 208 so Idunno:dunno:.

That exactly what happened to a 400 208 that I tore down,it looked like the welds failed that hold the pins and the parts got jammed up in the drum and split it.
You can see in this picture that thoses 208 planet sets are not hi quality compared to the 241

If I'm seeing it right, yeah, six idlers is better than four.:D
