Timing chain guide removal tool
« on: 23 August 2019, 11:11 AM »
Along with everything else I'm probably going to replace my timing chain and rails on principle.  I have reason to believe that there is some stretch.  My impression is that the output of the M100 engine is very sensitive to chain stretch.  This thing looks like it would be handy:

I note that the product description doesn't include the M100 engine, though it's hard to believe that there's something unique about the M100's chain rail design.  Has anybody used it or something similar?  Any recommendations or thoughts? Thanks,
-Dave

Dave maybe I am missing something here (won't be the first time ;D) but in my experience you do not need this tool on the M100.  Rather you join the new chain with a new master link, super simple.  To pull the pins for the guides you use a pin puller, which looks like this:

Daniel, you're not missing anything.  It is I that is missing things.  :o   I guess the slide-hammer thing is doing about the same thing but with all sorts of unneeded variants.  Thank you, gentlemen.

Sidebar comment - My engine will be coming out this morning.  I failed to REMOVE the engine shocks, just unbolted from the bottom.  Big mistake.  Anyway, in the course of all this I'll be repainting &/or replating all the odd bits, radiator, AC cooler and oil tank.  The only thing really worth mentioning here is the oil tank.  The shape is irregular and there are a couple places that dirt can collect.  They can't be seen and are pretty inaccessable to hose junk out. In 2 places there were caked dirt globs about 1/2 thick. The dirt holds moisture and slowly attacks the tank.  Fortunately mine just has surface rust, but it would just be a matter of time before the tank leaked.  Maybe this is old news to other 6.9 owners.  But if you haven't inspected the oil tank it seems like a prudent thing to do.

Less serious but more entertaining, the aux fan, ac cooler and radiator yielded an incredible insect collection.  For some reason there were hundreds of yellow jacket wasps!

Yes you can buy a removal tool but it is very easy to fabricate a slide hammer. The one I made worked really well even though at the beginning I doubted it.
