from slow to whoa! I little things I learned... - PeachParts Mercedes-Benz Forum

I just got done with my yearly maintenance on the ol girl before the winter really hits. Did a valve adjustment, glow plugs, fluids, and filters. I finally tried to tighten up all of my turbo/throttle linkage along with the bowden cable (complete with broken adjuster

).

Reason for the adjustment is because after putting the valve cover/linkage back together, my shifts were way too high. Looking at the linkage, it looked like I wasn't getting full movement. Tinkered with it a bit, trying one piece at a time to see where it was getting bound up. Seems like I found the right combo. I never really thought it was that slow before, but the difference is night and day. made drawings with measurements for the future. Dare to say it could possibly be considered "somewhat fast" now.

And I also figured out a couple of things for myself that seem like common sense now.

....when doing valves, don't release the locknut so much, as it just makes it that more difficult to tighten up after making the adjustment; which shouldn't be that far off if done yearly.

....getting that valve cover off.....I like to take off the oil cap, and grab it from there, and the turbo linkage bracket on top...

....two sets of wrenches for the valves. One short, one long handled.

...I love this car. It needs so much cosmetically, but it runs so nice..

I don't have the specs on your model, but the linkages really really need to be adjusted to the FSM not just to feel....

300SD W126 Throttle Linkage Specs

Specs^^

My latest 300SD has the most power. I can do 0-60 in about 12.5 seconds up hill. It is all stock and no ALDA adjustments. Trans shifts very well and the engine compression is excellent. Even on the highway, it always seems to have power to pass, etc. My first 300SD still needs some adjustments.
