[W126 Coupe] Timing Chain

[samsisic at comcast.net]

Greetings, 

I am about to have the timing chain replaced on my 88, 560 SEC, 90,000 Miles... 

I have all the guide rails (upper and lower), tensioner pivot pin and bracket, Timing chain and gaskets. 

My mechanic is suggesting that the lower rails need not be replaced. According to him, this makes a 4 hour job into a 30 hour job. 

I also have a NOS water pump that I thought should be replaced while at it... My mechanic says this is not part of timing chain replacement and un-necessary if water pump is good. 

Any thoughts/suggestions...? 



Thank you, 

Sam
