The lack of "typical" old Mercedes diesel engines noises is amazing. Just quiet enough to hear some other rotating tensioner or belt or pulley periodic noise... time to follow that path... the fact that old mechanic machines can run so smoothly is impressive...
Brings back fond memories of driving my uncle's 1980 240D when I was 16.....love that engine sound
great running of the engine, great result, great series of a "dead" 300D
unbelievable - thank you fpr the video
Really nice. Many years ago our local airport transfer company had a 1990 S124 300D non turbo. At 5 years old it had almost 200000 miles on the clock. I was always amazed at how it just started with what seemed like 1/4 turn of the starter. Hot or cold, no cranking required!
I have an s124 300tdt with 342k miles, and thats exactly how mine still starts, as soon as you bump the key its going.
Even though I'm basically a huge Volvo enthusiast, i really enjoy all your awesome videos about these old diesels! I remember the engines from my childhood in the 80's when almost all taxis were Mercedes diesels here in Denmark. I was just fascinated by the sound and the looks of the cars. I later became a semi truck mechanic and later had some years working on buses, before becoming a Locomotive engineer, and I also drove big locomotives with EMD V16 diesels. I just love the sound of a well built diesel engine and still get excited when you fire one up in your videos. As my teacher at the technical college said: the sound of a diesel is music to your ears. I agree. Thank you.
Thanks Kent, I appreciate the long videos. Particularly the "Kent's Garage" series from 2015/2016 or so, an enjoyable activity on a rainy autumn Saturday that I still occasionally review--they have resulted in more than a few Mercedessource purchases! Even though I don't even own a diesel, and probably never will, there is always something to learn.
This just puts a big smile on my face. So much more reliable than moderne cars with too much electronics
It truly runs like a butter! This injector rebuild is on my worklist next on my -83 mercedes w123 NA 300D 4-speed manual. I did order many useful products from your website alongside those new nozzles little while ago! Those look like very nice quality and cannot wait to see how nicely my good ol mercedes run with those after done! Even with old injectors it runs way better after i adjusted injection pump timing. Its currently driven 262 000 miles / 421 648 km. I have done basic maintenance and month ago also diesel purge, that helped with running and power significantly. I have learned so so much from you Kent, thank you! Greetings from Finland!
Outstanding Kent.... Spence series is right there with Digbby's
Kent, your attention to detail is terrific and to pass on your knowledge like this (so well documented) will keep these older cars on the road. It takes a lot of worry out of ownership and maintenance. Thank you.
Kent, I like your videos before I even start them because I’ve never been let down. Thanks. You rock
Received my glow plug chamber reamer kit today!! 2 day shipping across the entire country! Meticulously packaged- so excited to try it out. Thanks Kent!!
My 300cd runs well, but at 315k, it’s time for new injectors. I bought the Monark nozzles from Kent awhile back. This will be a winter project.
Good material as always. These mechanical injectors are beside MB used also in BMW and VW/Audi diesel engines. Worst ones I have take apart are the ones that have had water in or they have been clogged up from decades of sitting. Very easy to break them and ruin the shim and nozzle when you don't know what your doing. Bad injectors are just always one thing out of many why the German diesel engines will start to not run right. Just a personal experience. Old spence dose sound like a new car, hard to believe how different it is from what it started with.
Looks like a car one would buy now!!
That series reminds me so much of my apprenticeship sometime in the late 1990s when I learned to rebuild BMW pre-chamber diesels M21 and M51. No in-line injection pumps on these, though, but distributor injection pumps (if that's the right English term). I'd really love to get my fingers dirty now 🙂Thanks so much Ken for those videos.
Love it, and thanks for sharing 🙏
Fabulous. Cheers from BC Canada
Like Doc Hudson said in Cars: "Music, sweet sweet music."
Amazing sound
Great video
Good information
healthy benz .. i love itt
I use to have an 84 non turbo 300D, it would start instantly without glow plugs, very impressive
This man really legend 🙏❤️🌹
She was purring like a kitten after those injectors were rebuilt, thats a nice strong engine.
Great car!
big brother yu d best mechanic in da world o
Thanks Kent, as usually great movie and love to watch and follow. I learnt to watch out for a small o-ring at oil filter which I do not recall seeing in my engine. Can you indicate after how many seconds oil pressure should be raising up on the gauge at dashboard when starting cold engine after some days / weeks sitting still?

Kent - is there any chance of you selling a shim kit for NA OM606 engines? These seem to be nearly impossible to find, and it is making injectors for that engine much harder to service. Please let us know!
I have been working on this for a while. I have a tool that will hold the shim while you sand it down while it rotates against a belt sander to get the proper thickness. I know of no source for various size shim kits. I used this technique grinding valve shims for an Alfa Romeo 55 years ago.
@@Mercedessource Looking forward to hearing more about it in the future!
What is the diameter of the shims?

Что делать если корпус форсунки не откручивается? Он прикипел , как в таком случае открутить ее?
Извините, я не говорю по-русски. Пожалуйста, используйте Google Translate и конвертируйте на английский язык перед публикацией.
@@Mercedessource What should I do if the injector body is stuck and won’t come off?
@@Mercedessource I can’t take it apart and change noizle
You will have to use heat. Get it in a strong vise. Apply heat to the bottom section with a torch and use a socket and long breaker bar to break it loose.
I have just one problem with watching your videos....... and that is me wanting to buy an old Merc diesel just for you to tinker with
