Repair chain NP203 transfer case

[kikkegek]

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:

Motive Gear 11428

Cloyes 10-005c

2" chain
Motive Gear 13433
