Looking at Non running 1987 300SDL
so this belongs to my great aunt and she says if i can get it running its mine. it hasn't run in maybe three years. it currently doesn't have an alternator, so that might be the problem.
i ordered a rebuilt alternator from Phil at fastlane and a serpentine belt as the old one is AWOL. new alternator pulley as well. ordered all new filters, fuel and oil. what am i missing and what should i check before cranking this baby

With a good battery you can get it started without an alternator and belt. Did she tell you why she stopped driving it? You really want that information if possible. It may have just been because a new alternator was required.
Just do not run it very long without the belt as the waterpump is not circulating. It does not hurt to run this heat sensitive engine at an idle for a couple of minutes. Normally coolant circulation is not present until the engine warms to operating temperature. You may want to inspect inside the air cleaner. Just to verify a rodent has not built a nest in there. Roll the engine over for a bit without starting to get the oil on dried out internal parts. This may require disabling the engines ability to start with someone holding the shutoff lever on the injection pump. As soon as the oil pressure registers you have pre lubed. A little oil in the combustion chambers with the glow plugs out will help pre lube things as well. Leave the glow plugs out perhaps to blow that oil out and help the engine to roll over easily for the pre lube. That way the injection stop lever will not have to be held down either.

Barry has got it covered... I would also add changing the oil before cranking it as all the oil has made it to the pan by now and probably has collected water by now.
I would also add the step of spinning the turbo to make sure it is free. Then with the glow plugs out cranking it over to pre-lube it would be the best thing...

you wont be able to run a car for long without a alternator since the battery wont be recharging. If you plan to buy just make sure you dont have drive far.

You can run an old mercedes diesel for a lonnng time with no charging system. I figured out I could run the headlights on my 91 ECOdiesel for 2 hours before the battery would get low enough to not hold the full cutoff switch open. On a benz with the vacuum shutoff it'll just keep going and going and going...

With no belt though the water pump is disabled as well remember. I agree you could drive the car for several days easily with no headlights with a bad alternator though. The engine consumes no electrical current at all for practical purposes once running.

looks like a few people are forgetting something capacity called reserve capacity and how much components that are constantly on draw. The engine does consume electricity with the electronic diesel system, abs system, then when you factor in items such as wipers, radio, headlights, airbags, climate control. Most of those items you could go without depending on the conditions however you cant go without the eds system since the engine will not run at all. You can But I wouldnt drive the car since the waterpump wouldnt be working causing overheating.

The 603-powered Mercedes and previous will run indefinately without electricity, only idle-control will be lost which is not a big deal since the A/C won't be slowing the engine.
Electric fans would be helpful if the clutch fan failed, ... Anyway, yes the water pump is the only problem, get the belt on and you're golden. If the criteria is to get it running, run the fuel line from a fuel can directly to the intake side of the fuel filter, if it's got enough battery it should start and run. Then it's yours, you can figure out the details.

I would put in a fresh battery and install the alternator and belt. The drain out the oil and put fresh oil and oil filter on her. Then change out both fuel filters and pre-fill them with some diesel purge or biodiesel. After you have changed out the filters you can pick up some fresh diesel and put the diesel hose inside a clean can to get it going. After you get everything up and running your going to need to drain the diesel tank, there is no telling how much water and fungus is in that tank.
Good luck

okay, im not going to drive this thing anywhere without the belt or alternator. which is why i ordered them as stated in the original post. along with all the filters.
so thanks for all the facts about how diesels can run without electricity, but that does not answer my question. so drain the diesel and get fresh, good idea, will do change oil, already bought some 10W-40 for the job as well as a Purolator filter. new battery is a great idea. ill go get one tomorrow before i head over. couldn't find an new airfilter for the car, but will check and clean the old one to the best of my abilities. crank engine with stop lever held, another good idea. and free the turbo. any last calls, im going over there tomorrow

I'd say keep things simple and cheap to see if it will crank. I'd borrow a good 12V battery. Disconnect the old battery and attach the loaner with jumper cables (old one could have a short so that's why I'd take it out of the picture). Have fresh diesel in a container. Disconnect the inlet hose and stick it in your fresh diesel. See if it will crank. If it does you have something worth saving. Don't let it run but a few seconds. Then start spending the money on filters, oil changes, etc. If the engine is siezed, evaluate finding a replacement engine? Hijackers, good idea to at least read the original post before replying to the last post of a thread. Let's try to stay focused on helping the original poster, please.

Most diesel motor oil is not 10-40 though, its 15-40 , Did you get the right oil? It'll take two jugs. Be sure to prefill the fuel filter as you dont want to excessively crank it to start.

The 603 filter doesn't pre-fill, it just dumps to the crankcase.
I think I 'd just hook up temporary fuel and crank it, see if it fires. If so, then worry about changing fluids and filters.
