Different Crank Pulley #s
Guys,
anyone knows why the C43 & E55 & E55K has a different part #s of the Crank Pulley....??
C43: "112 035 13 00" & optional with "14 00"
E55: "113 030 00 03"
E55K: "113 030 01 03"
* is the different #s related to the less weight or bigger size in dia.......??
ZAYED,,

Sure your right,, but why all of M113 sharing a same Crank Gear & Crank seal & Flywheel & Spacer washers, in the meantime Evosport & AMS
provides a Crank Pulley for all M113 V8 Engines, they not mentioned if there are any kind of difference between them.....!?>!?

Evosport does not offer a crank pulley for all M113 V8 engines but AMS does...

Really?? How much did they charge you if you don't mind me asking? I had asked about one when I purchased the UD pulley kit and they told me they didn't offer one, they never mentioned the possibility of a custom one...

Im sorry, i don’t remember the price,,, i think its around "$700-$800", but not soo sure,, one shop here in Dubai arrange that pulley for me
from Evosport, but i don’t know with whom he contact with, i well ask that shop within 2 days and see.........

I've blown and rebuilt at least 4 P-car engines while experimenting with what I now consider to be stupid HP tricks. Those expensive lessons have led me to the jaded position that I'm currently in. Regarding the damper, it appears I can make one of two assumptions.
- Either the powertrain engineers at MB are wrong, and any 113 damper would work.
- Or the powertrain engineers have properly tested the parts, correctly overridden the accountants and said that despite the manufacturing, stocking, and all the other related costs, three different parts must be made.

Agree with you,, that's the important point i always think about,, we have some or other ways to free Hps, but for example do an intake
system could gains 4-7 hp, less risky, under "$250-$280", you can do it your self easily, Pulley can gives you roughly 12hp, "$500-$700",
labor with NO warranty around "$150", more risky,,> many people could not have that knowledge to involve with a heart of Engine balancing,
just need some hps without thinking,, i don’t have any issue with Pulley mod., but in my opinion its not deserve to go with something even it
may gives you 1% headache, we may have some other ways to free hps with relaxing minds.........

All N/A M112/M113's harmonic balancers are physically interchangable BUT the m113 55's have a differenct harmonic frequency due to the longer stroke.
I WOUND'T be fitting a balancer of a different harmonic frequency, MB doesn't redesign parts without a good reason.

Search and look around. You can find plenty of horror stories with modified pulleys

I asked the shop yesterday, the guy said he made a special order from someone called Simon Atik, he knows about that ordered,, i agree
with you, many many horror stories about pulleys, that’s why i removed it after only 2 weeks used.......

pulleys and torsional resonance
The reason the engines use different crank shaft pulleys is actually related to the torsional resonance of the crankshaft itself.
Get it wrong and the crank will become over stressed at certain RPM's and fail prematurely.
MB know what they are doing which is why crank pulleys and the integrated harmonic dampers are frequently not interchangable between engines.
Further it's certainly NOT good engineering practice to have a 'one size fits all' approach like certain 'performance pulley' makers offer.

Same here I prefer having a piece of MB engineered thinking than something which can make you engine go bang

Hi everybody,
I have a few questions regarding the crank pulleys. My car has the M112 E26 engine and I have read somewhere on the forum that somebody used to make aluminum crank pulleys for the 320 models. What sort of gains would you realistically expect from using a much lighter crank pulley then the cast steel one? (not sure if it's cast steel)
I know somebody who has been working with metal all his life and I'm confident he could make me an aluminum crank shaft pulley.
My questions would be
-Should I even waste my time with thinking about something like this?
-Is any special "machining" or something required?
-If he fully copies the one that I have on the car right now and he makes one out of aluminum exactly the same, would that work?

I would not even think about this mod. Harmonic balancers serve a very specific purpose. Others have had good experiences, some of us don't trust them at all.
A member here was building a supercharged C55 and his lightweight AMS crank pulley came apart sitting in traffic and shredded the front of his engine. He abandoned the project.
