Smile New to me 77' 240D

Hey yall! This is my first diesel MD. So far i love this little girl. I picked it up for basically nothing but there is almost zero rust. The only spot i see is a small spot on a jacking point. But it is just surface. At 246k miles it seems decent.

Now for the issues she has with the automatic transmission. It only starts in nuturel, park does not "lock", and it wont go in reverse. It does however drive amazing at 75mph. I took a 3hr road trip the day i got it. Other than maybe glowplug upgrades and eventually new injectors i think it is perfect.

Here are a few pics and videos:

Both extremes of linkage movement cannot be reached is worth checking out. Could be just a bushing. Get under the car and have a look. See if you can move it into park as a test.

Make sure you make provisions the car cannot roll.

Would driving it up ramps, blocking the rear tires, and e-brake suffice?

Yes. Sounds like you just need new bushings in the shift levers underneath the car. They are plastic - about $20 shipped.

Good luck.

Thumbs up Good score!

Well, couldn't get it started today so i went ahead and cjanged the fuel filters and got it primed or so I think. It wasn't wanting to prime so i pulled the fuel up to the primary filter and got it primed. Battery was to low after trying to get it started. I will try in the am as well as test the glowplugs which i believe are original. Fuel is dark gray/greenish blue color, which i believe is probably algae growth. I found the previous filter full of black sand. When i get some more coins i will drop the tank and have it steam cleaned then re-sealed. If i cant get it running i will crack the injectors and see if fuel spray out while trying to start it.


Edit: checked the blade fues and it is good. Been searching the forums for answers and not posting questions lol

As mentioned the transmission issue may be a bushing issue.

Part #11 is 115 992 03 10.

Part # 14 & 17 are 115 267 12 50.

Clean the fuel system, maybe with a bio-cide, and the glow plug update is a good idea.

The cable to the linkage atop the cam cover is your cruise control device.

Your vacuum connections need replacement.

If you haven't yet, replace the fuel jumper lines.

Looks like a decent example.

Keep us posted.

Well, it is still a no go. I had to manually pull fuel into the primary via a hand pump then connected it back in. I then proceeded to use the priming pump to get fuel into the system. I repeated 4 times until I got pressure in. Oh an it is the black pump.

Thanks for the info. I will get the parts ordered and the bio-cide is on order, should be in by the end of the day or tomorrow morning.

I will get to work on the vacuum asap as well.

Jumper lines will also be replaced.

As for doing the valves, that is something I haven't done before by myself and I will probably take it to a shop or maybe a local can walk me through it, I am just very cautious with working on internals.

Is the whole pencil upgrade kit with push button worth it from Mercedes source? I have had a few people say some rather distasteful things about them and I was wondering if that was the general consensus.

Is this the proper upgrade for the faster starter?


1982 Mercedes 300DT Starter*123 Type; (300D, 300CD, 300TD); 126 Type; (300SD)*(Baltimore, Maryland, 604-50928, Very Good, $87.00 )

Slow down a little. You have to get the fuel system in shape so you can pull fuel up with the primer pump. If the primer pump is having hard time the lift pump will be as well.

First things first and one at a time. You have verified the shifter linkage bushings are shot? If the fuel tank needs more than just a good cleaning. Go buy one from a pick and pull. Usually these tanks do not need a reseal anyways. It is not that hard to pull the fuel tank filter and examine things. Especially the tank filter.

Yeah, I hear a clunk also, could be an injector issue or maybe valves out of adjustment.

Adjusting the valves seems intimidating at first, but once you do it a time or two, not a big deal. There are special wrenches available, or some folks make them. Just bent 14mm open ends. Thin is good too.

Replace the valve cover gasket as well.

That starter will work fine.

I have owned only cars with the new style glow plugs so can't comment on that.

Do you have a good and fully charged battery? Are the battery cables /ground strap clean and tight? The starter sounds slow to me but should be on the edge of starting the engine if there is no air in fuel with good injectors and good compression. I also hear a rhythmic dip in cranking rpm. Anyone else hear that and what's causing it?

Ok im having a mercedes shop do the valves for me while i watch and learn. Quite honestly i suspect valves are a major player right now. It is going to set me back $125 but at lest i know it is done right. I don't have the wrenches or feeler gauges. The self priming pump seems to be working ok for now. The battery was fully charges, but i will double check the grounding cable. I believe i found the coolant leak 100% using dye and a uv light seem to be passenger side, right below the thermostat housing that connects to a large rubber hose. It leaked quite a bit in my 15 minute drive. I will add some pics and take new pics tomorrow in the sun light.

The pics are so large, it's difficult to tell much of anything.

There is a very short radiator hose on the side from the t'stat housing, check that for leaks.
