So I measured my timing chain on my 2011 Countryman and it is at 66.8mm. Does anyone have the part number for the new replacement tensioner? I also pulled the valve cover all is good down there.
Thanks

 

11317607551 This is the most common latest version but you really should check yourself on realoem.com You have not specified which Countryman or where you are in the world. 68+mm is the limit for complete replacement so well inside safe zone.

 

i thought 78mm was the shortest they have and also the faulty one. 82mm is the latest one in the market.

 

Thanks for the replies.

 

68mm is the tolerance using the measuring tool in place of the tensioner, tells you how stretched the chain is.
