1974 450SL -mechanical door lock problem

My mechanical door locks work well -from the inside of the car, at least. I cannot unlock either doors from the outside, using my key. It looks as if the key doesn't travel far enough do disengage them.) I'm thinking there must be some problem with adjustment of the two long arms that travel from the lock mechanism to the interior door locking lever? This problem is driving me a little batty.

The vacuum locks don't work, either, but I'm thinking that's a separate problem to be resolved AFTER the mechanical locking issue.

82 300SD Blower Motor Success Story

Installed new blower motor brushes today on my w126 '82 300sd -mine were worn down to nubs n(car has almost 400k on it) and I think the little brush springs had nothing to push against due to wear, Interestingly, I was able to operate blower with direct current from battery outside of the car on a vice but I think there was enough resistance in the car via internal wiring to prevent blower from operating. Car all cool -thanks Kent!

83' 300 SD Help with oil coolant line removal?

Lower coolant line leaking at the radiator. Got the two lines unscrewed at both ends and the clamp removed. Is it possible to remove these lines without lifting the left side of the engine and removing the motor mount?
If the mount must be unbolted, is it possible to remove just the screws that attach the motor mount arm to the engine and then just the motor up to slide the lines over the arm and under the engine?

300D 2.5 1991

n/a

300D 2,5 1991.

I have purchased a thermostat from Mercedessource and have flushed the cooling system. My service manual states that the thermostat body and thermostat for a turbo model must have a green mark. The Behr thermostat I removed has a green centre pin. The replacement one does not. What does the green pin on the thermostat mean. Also you show somewhere how to drill modify a new thermostat. Can you post a link to this.
Thanks in advance.

79 W123 300D- compression check w/o radiator in place?

Have a blown radiator which I pulled- How do I do an engine compression check to rule out cracked head or blown head gasket w/o the rad in place? Doesn't make sense to reinstall the radiator (-it's blown) or install a new rad just to test. Any ideas will be welcome as none of the mechanics down here seem to have any clue...

83 300D Turbodiesel - Strong vibration under load

I recently purchased this 83, 123 chassis Turbodiesel about 3 months ago. It has 160K miles and has been very well maintained. I recently replaced the injectors, glow plugs, adjusted the valves twice, with three weeks between adjustments, and the compression currently checks out at 340,380,380,380,380. I got quite a bit of benefit from doing a diesel purge, banjo cleanout, and ALDA adjustment. All of my efforts are aimed at bringing this car as close to optimal operations as possible.
