Repair chain NP203 transfer case

[kikkegek]

he guys,

I opened up my transfercase looking for a noise I cant track down.

I found a loose needle in the chain. see loose pin in top of photo?












The case was converted by the PO to parttime operation. So in LO and HI the chain does not move/turn.

Is there any way I can re-lock that pin? dont wanna fully rebuild the case if I dont have too.

Open to all options.

I did some research on the chain. I dont really think spotwelding would be a repair option. I guess replace the TC or chain.

did find some info on the chain, there are two models:

and found some info on a forum on the type of chain to use:

they used 2 different size chains in the np203 and if you go by what New Process says then they break down like this:


1973 - 1978 --> 3/8 Pitch x 2-1/2 W x 98 Pitches
1978 - 1979 --> 1/2 Pitch x 2 W x 72 Pitches


Here are some part numbers:

2 1/2" chain

Cloyes 10-005c

2" chain
Motive Gear 13433
