I spoke with a MB dealer tech about a year ago (experienced guy who's about 60 years old or so) whos worked on lots of 61x's and 60x's and said that this is very true with the shark tooth sprockets.
I asked him if he recommended timing chain replacement and he said no, unless the sprockets are replaced. It makes sense. In my thinking, the best thing we can do is keep driving using the original chain unless it's been routinely changed every 100k or so (saving wear on the sprockets). But I could be wrong. Seems like I've read a few stories of people putting a new chain in to have it break within under 100k miles. Too bad there's not an easy solution. Quote:

I have no clue how many miles but my 1970 220D has never had the timing chain changed. I got the car from my dad and he had it for over 22 years. last tiime Pierre and I checked the chain was just fine. oil change every 3000 miles.

no records with my "old smokey" daily driver, but the stuck odo is over 360K... been driving it for 2 years... adjusted the valves last year and have not been able to start the car since... next time I work on it, I will evaluate stretch and many other factors and see if I can save the motor.
I have two ready and waiting to get swapped in if I can't...

According to the FSM MB recomends changing the chain on the 603 if its stretched more than 4 degree's.

I have 157K on my newly acquired 190D (2.2L) and not sure if its been changed or not. The PO's widow did not know, but she said the Mercedes tech said it was fine. How he knows, I have no idea. He had been servicing the car for years, so I guess he knows more about it than most.
I am going to go through the stacks of records and see what all has been done.

230K on mine.
I asked my indie who has about 35 years of MB experience, he said he's never seen one break in his career, and has only heard rumors.

It would be an extreme rarity for the chain to fail with all tensioner and guide components intact. |

The dealer mechanic I talked with (very good MB diesel guy with lots of experience - 60 years old and worked on lots of 123's) said the same thing the guy on page number 1 of this thread (member with user name phidauex) said about the shark toothed sprockets. And it makes perfect sense... if the sprocket has a different pitch than the new chain, due to wear on it's teeth, then the new chain will be likely to break. When things don't match up, something has to give and it's not going to be the sprockets. It will be the chain. But who actually changes the sprockets??? Wonder what that'd cost. I'm sure it'd not be a fun/easy job. Probably something that should be done if a rebuild is going to be tackled. It wouldn't make much sense to do a rebuild and have the chain pop less than 100k later.

The sprocket on the top is easy, the one of the bottom is damn near impossible. I just rolled a new chain on with some new guides and tensoner a few years ago and its fine.
Everything looked clean and good inside mine, no wear on the sprockets that I could see. At the rate that I drive my car 300k miles is at least 6 years away. Eventualy all the seals are going to be shot and leaking everywhere, so I'll probably rebuild it to get rid of the leaks before anything actualy lets go. Besides you 617 guys should be more concerned about your oil pump chain than the T chain. A few people on this forum have lost engines because of those. What it comes down to is that these engines are just getting plain old and tired. How much do you want to tear into a near 300k mile 25 year old engine? Its not worth it.
