Today I removed my camcovers, alternator mounting bracket, plugs and leads and then removed the chain tensioner.
I had an original chain so ground the ends off a link with my Dremel and then connected and pulled through a new M-B genuine chain (Chain and tensioner purchased from the Classic Centre, Irvine, California).
As I do not own an M-B valve spring compressor I could not remove the cam followers to disconnect the Right Hand Cam so carefully using the "three Vice-Grip Method" I slowly fed through the chain turning the motor over with a 22 mm spanner on the end of the power steering pulley as recomended by Styria.
I own the necessary 50mm socket but it would probably have required removing the fan to use it and the power steering nut was perfectly adequate after the belt tension had been set to specifications (using a Crikit).
I found religeon a few times when the Right cam would go down the back of the cam and cause the sprocket to jump forward with a lurch but I never jumped a tooth and was greatly relieved when the first link came around and slotted into exactly the correct adjacent sprocket to the other end - just required the master link to be fitted and the spring clip fitted.
End result was 16 degrees of chain stretch is now 2 degrees.
I have not fitted the tensioner as I need a new sealing ring and I 'll see what is in the local shops tomorrow but have ordered one at the agents.
I also have a package coming from AutohausAZ and this includes a selection of offset keys.
The Right and left cams appear to be in perfect alignment so I am assuming 2 degrees of advance to the RH sprocket will correct all - we will see.
I have taken photos of the whole procedure and am happy to make a pictorial of them if anyone is interested.
