Argh, did I fry the starter motor?

I replaced all the fuel filters. But I forgot to fill the new main filter with diesel. Well, no big deal. I figured, after a few cranks it would get going.

Well, it cranked and started on the first try, but died shortly after. I expected that, so after a few more cranks it almost started. But, the cranks started getting weaker and weaker, and eventually it wouldn't crank. I was planning on replacing the battery soon, because the previous owner had a generic no-name battery in there that didn't look too good in the first place. Well, I went with a friend to pick up a new battery. No go. Couldn't even hear the starter motor going. Currently the new battery is hooked up to a charger (I am somewhat optimistic) and I'll try it later tonight.

I'm HOPING that the starter is not fried. If so, how much $$$ is a new or rebuilt, and is it something that a DIYer with Mercedes diesel experience could do?

speedy300dTurbo,

I hope your starter didn't die, but if it did try FastLane. I got a rebuilt one from them a year ago. I bought the heavy duty one for the 300D instead of the listed light duty one for a 240D (I put it in a 240D). Anyway, they are rebuilt by Bosch and that means it is they likely have been remanufactured with new windings and insulation, which are the things that Diesels wear out from lots of cranking. A new solenoid, bearings and so on may also be needed, but it is the windings that uniquely suffer on a Diesel, from just the event you did, or the repeated starting attempts in cold weather that is also typical.

All those Amperes heat the windings which destroys the insulation over time. In general the rating of the motor is not a continuous duty rating, and when you use it in a continuous fashion, you over load it and it quickly heats up. So it is important for a Diesel to have new windings and new insulation as part of the starter rebuild process, or it will just fail again.

So, get the biggest, most powerful motor that fits your car. Is this for the W124 body? It might take the unit from the 350SD/SDL, which should be good enough to start the 3.0 in-line 6 or 2.5 liter 5 with no problems for a long time to come.

Never did the job on a W124 so I don't know how hard it is. On a W123 it is a struggle, but definitely a DIY'r job. Good Luck, Jim

speedy,

you are supposed to fill the new fuel filter with redline or injector cleaner or something of that nature.

There is a primer pump that you can pump up the lines. you could even crack the injector lines with a wrench and pump til you see fluid, then it should surely start.

Starters are pretty hard to wear out. Maybe you left the car in drive or something.

My brother starter has been making noise too, w124 diesel 150000 miles...

Let me know if you do the starter and tell me how hard it is,


Austin

Speedy,
I doubt you have a problem other than a bad battery. I recently needed to get my 603 going on a cool (55 degree) day without benefit of glow plugs. I cranked 3 full one minute intervals with a 30 sec. cooldown in between without any apparant damage to my starter. You can crank for quite a while but be sure to let it cool down periodically if you do. By the way, my car started. Useful to know if you ever blow the glowplug fuse like I did.

The W124 diesels don't have a manual fuel priming pump.

Most likely cause is that your new battery has been sitting in the store for some time and is discharged. Charging should bring you back into operation, I hope.

For the benefit of "next time" at least fill the new spin-on filter with diesel fuel or LubroMoly Diesel Purge which is mostly diesel fuel.

Good Luck,

If charging the new battery doesn't work, check the safety swith -- try neutral rather than park. If it works, you need a new safety switch (I think it is on the tranny) -- long cranking can sometimes fry them.

And check that new battery for electrolyte! If it is dry, take it back, ditto for it it won't take a charge.

you know how to replace shifterbushings, well follow the rear arm down and where it hooks to the shaft, well there is a plastic piece that goes into the neutral safety switch that is where it is.

Where is the neutral safety switch located on this car?
