I am interested in learning if the crank position sensor trigger wheels are all the same, different, etc on the following flywheels:

A) 1986 m103 300sel w126 (5-speed), one of the cars I own.

B) 1993 m104 3.2 300se w140 (weird short lives setup with electronic injection, but a rotor. LH Jetronic?)

C) 1995 m104 w124 car. Is this “Motronic”?

D) 2002 SLK m111 4-speed: this one has a setup that looks similar to this flywheel, with a gap for two of the trigger wheel teeth. I’m not sure of the number of teeth.



Maybe it’s 58 with a gap for 2. 60 sure makes a lot of sense for a 6 cylinder and a 360 degree circle.

Does anyone happen to know how many teeth are on each setup?

Do any setups use a magnet? Or do they all have just teeth on a trigger wheel?

The later motronic cars should have whats called a 60-1. Meaning that there would be 60 teeth if on e weren't missing. So it has 59 teeth and one large gap for the missing tooth. Not sure about the LH and earlier systems .

Not 60-2 like the one pictured above? The slk 2002 flywheel I saw was missing two teeth like the one pictured above.

The 111 has a 60-2 wheel. The 103 I'm certain is a 3 segment. The early LH 104 I'm fairly sure is also a 3 segment. I'm not really sure about the '95. A '96 would certainly be a 60-2

I’m trying to learn what a “3-segment” is.

I assume this is one:

Yep!

1995 M104 will have three segment with a magnet on like on the flex plate in previous pic. M103 doesn't have the magnet.

So it sounds like there’s basically two styles. I understand the early m119 have four segments, but it’s either a
- cyl/2 or a
- 60-2

Does that sound correct?

Oh. Where’s the magnet? Just one? Or one on each segment?

Just one. You can see the backwards J looking thing on the segment to the left in your pics of the flex plate above.

Ahh... thank you. I think I see it.

It sure seems like a window in the bell housing would be handy if you have a crank position sensor.

Over the past few days I think I have begun to understand better. At the time of the creation of this thread, a friend had an SLK 6-speed, and I (now) have:
- 1993 300se w140 m104 LH injection with cap and rotor and ignition module with crank position sensor, just like the m103 k-jet ignition it seems.
- 1992 300te m103
- 1986 300se m103 (euro)
- 1986 300sel 5-speed
- 1985 190e 2.3 4-cyl 5-speed (OD)

The first two cars are worthless, and could be cheap fun. The salvage title m104 in the w140 has only 115,000 miles I think, the reason I bought it. Unfortunately I believe it has ASR. The wagon seems to have a blown head gasket and would run until it warmed up. Clean title, and decent interior. The 1986 300se is probably the best body of them all, completely rust free. So even though I was originally thinking of putting the m104 into the wagon with a stick, or maybe just putting the 5-speed into the w140 as a test bed, I really don’t know what I’m thinking, just looking to make the 5-speed work with a straight six, preferably a powerful one. Blah blah.

The important thing that I discovered is that all my cars have no magnet on the flex disc / flywheel because they all have cap and rotors. If they don’t, a magnet is required, at least for the three tab style, probably the mid 90’s m119 four tab too I’d assume.

I’m not sure when they went to the later style with tons of teeth, but that’s what the 6-speed slk trans had when I looked at it.
