Just got this car two days ago Black 82 300D turbo diesel. straight body, clean interior, new tires, was running two weeks ago at 347,000 miles.
PO knows squat except it wont start...
For 500 bucks I figure its worth the gamble...

Day 1 trailer home, look it over, battery worn down from po and all the lookers tryin to start. pull fairly new batt and charge...

Day 2 hook up batt showing 12 volts, check grounds, gp relay reads 9.? volts, air filter clean, oil dirty, 1/2 tank diesel, see new fuel filters...give it a whirl.
Motor turns over, but slowly...with good batt I think probably a week or worn out starter/solenoid ?????

Day 3 was going to check wiring and maybe cleanup starter(quite a bit of oil n gunk down under), maybe go ahead and pull starter...
But two days worth of storms just blew in, so here i be...
My first MB, first diesel, so i could use any advice yall might toss my way.
Theres other issues i see need tending to, and probly more to come, but obviously i gotta get this thing turnin over right to tell much else?

Thanks guys I've learned a bunch just searchin the threads!!!

Accessing the starter was much easier from the top on my turbo 617. As was mentioned, you'll have to remove the air filter assembly, the battery tray, and the heat shield.

Loosen the transmission dip tube but there is no reason to drain the trans unless you are changing the fluid/filter. There was no way I could get an allen socket on the top bolt, so I cut an allen wrench off to get a fit. It would have been more helpful if I had bent it a little more acute. I had to use a pipe "extender" to break it.

I read of a good tip after I struggled with the top bolt. Cut a portion of an allen bolt off about 1-1/2" long and insert in bolt head. Then use a box wrench on the stub to break it. Then use a gear wrench to remove.

After replacing the starter, I found that the case on the old one was loose. I probably could have just tightened the case bolts and reused the old one. The PO had neglected to replace the block bracket bolts and I figure that was the cause of the loose case.

Anyway, there's nothing wrong with a new starter. Banging on a starter from underneath in a parking lot is less than dignified.
