Getting the starter out of a 1983 300D is a real PITA. I changed the one in my 240D last year and it took about 30 minutes. I fought this one for 4 hours and I finally got the old one out, but am waiting for the new one from fastlane.

I used ken300d's method where you use about 2 or 3 feet of extensions, a universal joint, and the 10 mm allen socket. I quickly broke two universal joints trying to get the top bolt out. I ended up using an impact wrench universal joint, an 18 inch breaker bar with a 2 foot pipe on it, and my 200 lbs of fat arse to break it loose. At one point, I even tried heating the bolt head but gave that up when the old oil around the bellhousing started to catch fire.

I've read on this board where people recommend used loctite (red, I think) to keep the starter bolts from coming loose. I'm a bit worried about doing that considering how hard it was to get this one out. If I ever have to take this one out again, I don't want it to be this hard.

Any suggestions?

It's an aluminum housing and a steel bolt, you don't need Locktite! Without antiseize, the last thing you need to worry about is the bolt coming out!

Just tighten to correct torque, I've never heard of one coming loose.

I had one come loose. I think I just didnt get it tight enough. It was all the way out but It didnt come out. I just tightened it up and havent had any problems since then. I know exactly where you are coming from on 300 starters. I put 3 on in a weekend once. I removed one, put a rebuilt one on, it didnt work, found a used one, it didnt work, found another used one and it worked...for awhile, I ended up buying one from Autozone and had to replace it once but it was free the second time. So how many extensions did you use to get the top bolt out? I use a 10" with wobble headplus another 10 then a 6" wobble then put allen head socket on. I havent done this job in awhile nut it is probably the second worst I have done besides oil cooler lines.

That job is a real drag.
The allen head socket is the only saving grace.
Getting it out of the hole is a PITA big time.
I must say, though, now that I have done it twice, it does get somewhat easier...

I'm not going to use anything on the large starter bolts but I am going to use a very little red loctite on the 2 small 10 mm bolts that hold the front bracket on the starter and then on the 2 10mm that go into the block from that bracket. On this car, the 10 mms that go into the block had backed out about 5 full turns so the front of the starter really didn't have any support.

I believe I used the 10 mm bit, the air hammer universal joint, 2 3 inch extensions, 2 10 inch extensions (all 3/8s) then a 3/8 to 1/2 adapter, then a 6 inch 1/2 inch extension, then the 18 inch breaker bar, and 2 foot pipe.

I've wrenched on MB diesels for 15 years now (300sdl, 240d, 300d), and the upper starter bolt is the toughest job I've had.

Man, don't tell me this, I'm about due a starter..

I tried to get mine out once and broke a swivel socket. I gave up and just took it to the dealer. Cost me $435.
