Check with your local trans shop. It is a "standard part" for the NV125. If you check the round tag on the "$2k box" you can take that number to a trans shop and they can order then chain for you.

Hello all !
I am with the same problem here about my transfer case NV 125
I am in Canada, tried to speak with my local transmission shop, they told me that they not sure if they can get the chain and bearings for me for this type of transfer case and sent me to the BMW dealer.
Maybe some one can point me to any US supplier who may have the kit for this type of the transfer case. Basically I am looking for the chain, bearings (looks like my ones are dead) and the kit of sealents.

I would apreciate any help on this.
Sorry for my English :dunno: (French Canadiene)
