M104 Crank pulley bolt torque

Car: 1995 C280, Engine: M104

I need the torque value for the bolt holding the vibration damper to the crankshaft. I can't find any reference to this for the M104 on my CD (plenty on M111, 112 and 113) and I haven't found it with the search either.

That is Job 03-3420 on the 124 CD . For 124/202 chassis.
Might be the same on your CD .

Arthur, thank you once again.

The documents on the W202 CD carry the WIS naming convention, so 03-3420 is something like AR03.30-P-1600C (which happens to be the procedure for the M111).

I have checked every PDF on the CD and can't find the M104.

I am surprised by the 400Nm. My M103 paper manual calls for 300Nm and with the M104 being an evolution of the M103 I thought it would be pretty close. The M111 is also 300Nm. The M112/113 isn't a good reference because they call for a combination of 200Nm followed by 95 degrees of further rotation. Anyway, it shows that assuming something can be dangerous.

I am going to have to borrow a torque wrench to do this one. My Snap-On 1/2" drive tops out at 338Nm.

Yeah...the 124 CD does specify 104 engine, with the difference being in which version crank washer set-up is used. They also mention lubing the bolt threads and washer/s..

There is quite a bit of difference 103/104..

You want a wrnech that has a 350 Nm as a center range to be accurate.

That is very surprising, as all C280/202 chassis used the 104 HFM/SFI engine...

Arthur - Maybe I should be a bit clearer - I can't find this particular procedure for the M104 on the CD.

But I do agree with you - it is very surprising. STARtekinfo lists is a later version of the CD - P/N P-2700-202-06. Mine is P-2700-202-03. Maybe the later CD has the procedure.

That is what I was referring to...one would think it would certainly be in the CD for 202 chassis.

In the 124 CD , it is Under Engine/Front cover jobs.
And also surprisingly, it did in fact mention for 124/202/129 chassis..which I found odd in a 124 CD...but I attribute that to the fact that all those chassis use some form of the 104 engine..[ which is why they mention both washer types]

Arthur - I went through the CD again and there is virtually nothing on the M104. I think that may be because M-B publishes the following two manuals for the M104:

P/N QL-6516-2599-02 Engine M104
S-2599-093 Engine Manual M104

Anyway, I know the procedure and have the tools (flywheel lock, pullers, seal arbor and a borrowed 400 ft/lb torque wrench). It is just the torque value that I was missing and I wasn't comfortable transposing the specs for the other engines to the M104.

If you weigh a little under 200, just get an 18" breaker bar and stand on the end

If he weighted 200 lbs and wanted 400ft/lbs of torque , he would have to
have a 24" breaker bar...

T= Force X Length. [ @ 90 degrees]

Gee, thanks for the Statics 101 refresher. Only the required torque is not quite 300 ft-lbs, per your original post.
