I bought a new timing chain years ago, but never installed it. Instead, I decided to install an offset woodruff key at the cam gear:
Greatly saved the time and trouble it takes to replace the chain, which will eventually stretch anyway. By using the offset key, I can retain my broken-in/pre-stretched chain, and keep proper cam timing, probably indefinitely. And, because the keys are available in 1-degree increments from 2- to 5-degree offsets, you can set the cam timing to within a gnat's ass.

Kinda quiet on our MB e-list.
I finally got some time to do the MB 15K service on my '85 300D: Oil
change, all filters, adjust valves, check timing chain, and a diesel purge.
The valves were spot on, so just a check no adjustment, the timing chain
was 5* off, which can start causing timing issues, though not an
emergency according to Kent at Mercedes Source. I'll plan to replace the
chain next year.
Anyone change a timing chain yet?

I noticed the 'Accelerator Linkage Mount,' on the firewall, was loose
inside and the inner ball was crumbling, so I glued it back together for
now, and ordered a new one from FCP Euro. I called the Mb Classic
center, and heard that MB discontinued this part, though there's still
some for sale out there. If yours is questionable, you might want to
replace it.
