Hi, read recently questions about how do I know if I have a revised timing chain tensioner fitted? Below is a photo of three tensioners the first one is the original with just a hex head the other two are revised items which are ok . It's a bit tricky to locate where this is but all you can see of it on your engine is the head of the tensioner obviously on the cam chain side of the motor about a third of the way down and more to the front of the engine.
It's still possible to have a knackered chain though even if a new tensioner has been fitted!
Hope this helps :thumbup:

Are the second and the third one interchangeable? Which dimension is the 25mil one?

Hi I would have thought so as they fit into the same housing looks like the thread size are the same.

Is it not the depth of thread the difference looking at 2 and 3. If this is the case then, NO.

1 and 2 have 20mm thread depth, 3 has 25mm depth, therefore threading only to 20mm will leave 5mm difference.

Don't interchange and risk damage without thoroughly checking with your dealer ( not that dealer! ).

good thread though.... get it... thread... oh never mind. :crazy:

:lol: Laugh and the whole world laughs with you.... or is that at you? :eusa-think:
