On the 617.952 Engines I think the enough of the Crank Dampener has to come off in order to pull out the Long Timing Chain Guide Rail Pin. If so that is extra Work.

Correct, if the tension rail is to be replaced. Cam sprocket comes off too. Replacing the lower slide rails also requires removal of the balancer. Both are easier to do with the water pump housing out. The job snowballs quickly when it expands beyond just replacing the chain and tensioner.

I had it done for $950 about 2 years ago from an Indy, including all parts.
I had read about the process a lot here, but decided to have him do it, per his expertise, better tools, and hearing about some mishaps when non experience folks have done it. Unfortunately, he retired and moved.

This is a good DIY on changing the Chain and all the related parts that CELL did a couple years ago.

The approximate cost depends on the hourly charge, and how much you want to replace.
Primarily the banana rail and chain were replaced on mine, but while I was at it I went ahead and had the tensioner, tensioner spring (separate on my 617 turbo), and corresponding gaskets replaced. This meant removal of the water pump, water pump housing, thermostat housing, and crank pulley to access the lower pin. You'll also need the tool to crimp the chain links (master link to ends of new chain) as well as the holding tool (if necessary) to hold down the chain to the sprocket so it won't fall off. Here's a photo documentary of what you could expect W123 timing chain replacement - photo references

Thanks for all. This guy is the best I have ever seen. Super anal and all,he has machine shop and has rebuilt probably 1000 617s as well as lambos ferrarris, bmw etc. We share a Hatteras sportfisher that I own and he finished the job, rebuilt the 6bta Cummins etc.
I'm just anal too and keep a mental balance sheet in my head so we are always about even. Thank you all again |
