W114 250 CE timing chain and tensioner replacement.

Dear all,

Today I replaced my timing chain and tensioner. 

I could only use the chain locking clips (circled in red) once while inserting the new chain while pulling the old one. After that, when I removed the clips, they bent too much, so I no longer trusted them for the final closing of the new chain. The old chain itself was about 5 mm longer than the new one.

For the old tensioner, I needed 3.0 kg to press the push pin in, and the new one 5.5 kg. 

Below are some photos with a detail of the one direction check valve (ball with holder). 

I have one question, although I don't think it's really critical. See the first picture: does anyone know the tightening torque for a, b, and c? I couldn't find them in the VdH flipbooks for my M114.980 engine. Thanks in advance, and enjoy the photos.


PS1: and i needed the Dremel tool to open the old original chain


 


Kind regards, Marc
