Hey all, the local head tech that works on my car just told me that he learned that Mitsu apparently has released an updated timing chain. Im wondering if anyone else has heard of this? A part number would be awesome as im getting ready to swap my chain for a new one before spring.

Ive been following that thread, but they make no mention of an updated chain with a new part number. My friend told me he will look into it when he goes back to work on Monday, if I get a new part number ill post it here.

It's in that thread man. New part # 1140A073. Apparently the part is so new that dealerships don't recognize that part # yet. But whenever guys got new chains, it had that part # on the box.

I just spent some time talking with some dealerships about this part number situation...

More info on the part numbers for anyone ordering a chain:


MN183891 is the original chain. Not only that, but it seems that most dealerships you call will order this part by default because it's what shows up in their inventory database and they will say there's no record of that part having been superceded (recently updated).

1140A073 is the new chain. If you give a dealership this number, they will not find it in their inventory database (at least the ones I talked to didn't). They had to go look this up in the actual Mitsubishi parts catalog upon being provided with the last 8 of the VIN#. The new chain is also about 20-30 bucks more expensive (list $134.14)

Is this a recall of some sort or just an update?

It is only a update now on the part but who knows if a year from now that could change. on the cam install you can do it with out taking the timing cover off but I would say to go on and do it right and replace the chain. I have another one that i have to replace the chain in next week.

Yeah I would do just that, the chains from the pre 2010 models are stretching and causing alot of damage, that's why I never bounce off the rev limiter, I don't use the two step launch and I check the oil at least twice a week as its rumored it could be down to poor lubrication, although Irmerm's chain stretched through wear and usage, one day it was driving fine...the next day it wouldn't even start.

I'm dreading this happening to me...:confused2:

Is everyone going to swap theirs out for this now? I just got my AMS crate motor and I think they have installed and timed the motor with the old style (brand new) chain. I was just going to drop the motor straight in but now I wonder if the chain really requires to be updated.
