Re the pensioners. The are rubber faced so you should expect a pair of grooves in then as the tensioner works by bearing on the chain rollers not the side links. I would expect the tensioner to exhibit tram lines very soon after the engine is first started, and it shows the tensioner is working.

I know a few like that
Really interesting stuff Ian.
Like I said in the "other" thread, I was definitely told by a renowned specialist to avoid German. I can see where the improved quality of the German chain would help the engine in this critical area. I would have expected maybe swapping them out every 30-40k miles when the guides and tensioner shoes are worn.
BUT one interesting thought based on info here, prestretched, pretensioned whatever, surely in this state the only give that the tensioner would have would be as the tramlines develop until such point as the rollers are in contact with the tensioner shoe as Matt suggested and makes sense. Therefore if the chain will stretch no further then the tensioner should last as long as the chain?!? The same would go for the guides I guess.
I am hanging onto my 33k mile old guides and renold tensioners. have a nasty feeling that 21st century items might not last that long!Stags and Range Rover Classics - I must be a loonyComment

I posted pics of iwis and rolon chains a while back here http://www.stag.org.uk/forum/showthr...is+inside+link post 65 iff you want to compare.Mine came from LD parts so sure they are genuine Iwis.

Just looked down the filler hole at my chains. They are LD Parts boxed IWIS chains (IIRC the box even had a hologram sealing sticker?). They certainly don't have those rough "punched out of a steel plate" edges - they are smooth; exactly as the LD parts photo. They are a bit wider than the chains I removed.The answer isn't 42, it's 1/137Comment
