1957 Mercedes-Benz 300SL Engine Test

Posted by admin on August 30th, 2009 and filed under test only |

After final embly of the 300SL engine, it is time to bench test. No only is this fun, but it checks for oil leaks, oil pressure, engine temp, timing, etc. The final run-up was only to about 3000 RPM since there was no load on the engine.

    Saw my first one in Germany the year it came out. It was a red one. Top was down and the driver was a nice looking blonde lady. I’ve always remembered the car and, as I was only then 23, the blonde too !!!

    3-pt star motor gets a 5 star rebuild. Sounds smooth and powerful like an aircraft engine, I bet that SL flies now!

    Recently had the rare opportunity to check out that motor underhood a beauty 61 300SL roadster in a shop. The mech said convertibles are actually rarer than gullwings surprisingly.

    Forgive my ignorance, didn’t Merc bring the 8cylinder out in a road going car? A true work of art, it gives me goose flesh everytime I even see a picture of one. A great pity Merc didn’t make more of them

    Easy, the 6 cylinder 300SL does NOT have desmodromic valve train. The 8 cylinder racing 300SLR DOES have desmo valve train.
    The 6 cyl method of valve adjustment is very conventional for the time, an adjusting screw that acts on the top of the valve and a jam nut to secure it. For more info on this subject go to Wikipedia and type in desmodromic. Thanks for watching and for the comment.

    Very nice work, but how can you fail to mention the desmo valvetrain?

    I rec’d another msg from you, more detailed and responded to it. If you did not get that response thru YouTube, let me know. The short answer is I think the dif noise you hear is normal for a 50 year old race car, which is what the GW is, in which you sit about 16 inches away from the rear axle.

    Thank you. I wish the video work was better, not so jerky and better lighting. It was my first effort. It took a great deal of editing. You Tube allows 10 min or 100MB of video. I did 9 min of vid and was way over the 100MB limit. There was a great deal more info and running of the engine in that 9 min clip. So then I had to severely edit to get under the 100MB limit. The orig clip was more fluid and followed the engine run from start to finish. With no load, I only went to 3500 RPM.
