Chain Tensioners for 1999 996 M96


Recommended Posts

Ok, called a few dealers and here's what I found out.

56 (replaced 55) does not show up as being superseded by 57.

Only 54 shows up as being replaced by 57.

I guess when I get my hands on 57 next week I'll share whatever info I can about it.

FYI the dealer could not find 57 in his version of PET either - had to go into Polaris for super session/availability inquiry.

Please share your findings. I am looking at replacing my tensioners as well in my 2000 C2 Cab and your experience would be helpful.

Well, here you go -57 arrived today and here it is. Basically it looks exactly the same as the old one.

Perhaps there will be a TSB or more likely it will just show up in PET with the next update.

The only difference from the three tensioners is the one for cylinders 4-6, it has a much flatter head and a allen key to it.
