Hi Guys, a friend of mine has recently bought a 2005 3.0L TD6. When setting of slowly we were hearing a slight nocking, after having it in the air we noticed several worn bushes and anti roll ling with slight play. After replacing these and getting used to the vehicle, we decided to give it some hammer.

When setting of fast from a stand still there were a awful banging which sounded like it were coming from the back, so we had it in the air again swinging from anything that can move. Nothing had any play, so we decided to get it a boot again. This thine it sounded like it were coming from the middle, so we got some wireless hearing devices and placed them around different parts, We finally narrowed it down to the transfer box.

We have removed the transfer box and opened it up to find the chain has a lot of slack. You can also see scoring marks on the case interior from where the chain has been banging.

Unfortunately I can not find a replacement chain from any where, this was on a Saturday afternoon so many places were closed.

I have seen a replacement on Ebay at the cost of £245 + £8 P&P, which they claim cannot be bought from the supplier. There are not real marking or numbers on the chain other then "morse HY-VO", there is nothing i can find on google other then information the P38.

Does anyone know the part number for the chain? Or know where i can get one cheaper?

The only other information I can find is it approx 1.7 inch wide, has 45 links and has 1 Blue link, the transfer box casing also has BMW NV225 stamped on it.

blue link is there to ensure its fitted the right way round ,id be surprised if lr supplied it as a part nowadays,you can get morse chains made up to size

Thanks for your reply James martin. I did manage to call several firms that did morse chains, but they said they did not make automotive chains.

The reason i mentioned the blue link is because some reserch I did yesterday on some BMW and other RR chains, they spacifically mentioned about some chains having one or two blue links.

I can find P38 chains all over, but why nothing for the L322?

p38 had a reconditioning program so spare part availability ,i presume l322 doent, just fit new,

They were never expected to last long enough to need a replacement chain.

Thanks for the replies, one has been sourced in the UK at less then half the price of the Ebay item.

I'd be very interested to hear how it goes, I have the same clunk when I throttle off and back on again and I did the same with a 6 way electronic stethoscope which tracked it down to the transfer box
I had a quick look around and was quoted £700 to refurb the TB not including any fitting but not done anything yet.
I guess it's the same unit on a 4.4 petrol ??
