617 starter in a 616
 

Has anyone ever replaced the starter in a OM616 with the starter from a OM617A? I remember someone talking about it a number of years ago but I cant seem to find the thread now. I almost got stranded at work last night because I decided to drive the 240D to work and was there till 8 and it was much colder than I was expecting so I had issues getting the car started. Most of the issues are due to me not preforming a valve adjustment last summer when I should have :rolleyes: but the starter began making noises like the bendix was failing right when I finally got it going. I am already planning on a valve adjustment before I drive it again since it is way overdue and thinking about finally taking the plunge and upgrading to the pencil glow plugs. I never had these issues living in the south so now I know how all you northerners feel with your winter starting issues;)

Long story short would installing a turbo starter in the NA motor help with starting since they are more powerful?

Yes.

same part number... 240/300/300A... only different part is on the CA 85...

The resisitance is one cylinder at a time so same size cylinders equals same starter, unless superceded. I have about four spares so if you need one I can supply.

they seldom wear out though.;)

And when they do it's a whopping $15 for new brushes and a new carrier.

Was it making that whirling sound?

Turbo starters are different than NA starters. However, I think most parts places only carry the turbo starters nowadays. If you dig deep enough you can find a different number for the NA starters. There was a thread on the topic about 5 years ago.
When I replaced the starter in my 77 NA with 58k on it with a turbo starter, it definitely spun faster.

I tried to replace the starter on my '77 with a turbo and found that the nose was too long.

Interesting. Mine went right in . Was your engine a 617 or a 616?

240D vs 300TD Starter
 

Here is a thread on the same subject.

Yes it was. What does that mean?

I will read through the posted thread as well.

You might want to put a little more thought into that theory. A four-cylinder engine has one piston on the compression stroke at a time. An engine with more than four cylinders has more than one piston on some phase of the compression stroke simultaneously with at least one other piston.

You are correct, but we don`t know what engine Tom was refering to. He may be refering to the 616?


Iam wondering if when we buy a new to us rebuilt starter from what ever source we get it from, which one do we actually recieve? 616 or 617???
or are what is in the inventory a mix, or are they all 617 starters now???

All I know is back when I was driving my 190c fintail, I bought a 220b fintail for parts. I was going to switch the starter figuring that the 220 starter would be more powerful due to the larger displacement. When I started to put in in the car i found the 190 starter was actually noticibly larger than the 220 starter. I always figured it was because of the bigger pistons. I guess a six would have two or more in various stages of compression too by your theory.

So maybe you better tell the MB engineers to think more.;)

Yes, they will interchange.

That said, I had an old salt dealer tech tell me that there was a slight difference in an early 616/617 and a late 616/617 starter such that they would bolt in place but were different such that one combination, early on late or late on early would put it in a slight bind.

I have never confirmed this to be true, but I thought I would pass it along.
