BI-Performance

We are finally now offering a repair service to your M113K cranks if it has been damaged due to incorrect installs, and or defective pulleys.

The damaged crank is corrected back to within MB tolerances, and at the same time, we have a full keyway cut the entire length of the snout

The program works like this, you send in your damaged crank as a core exchange, and we send you one of our B.I.P. units for the cost of $795.

Let us know if you have any questions, and this is our first unit that is available for sale that came out of Craig's E55.

Thanks again for your business, and continued support, regards B.I.P.

Tech-Tune

Thanks for having this available, hopefully you'll never need to sell one. (sorry if that came out wrong)

Great thing to offer after several of us have damaged cranks in the past.

Cool!

Although to be honest if my crank snout ever got damaged i would probably burn the car to the ground and blame it on the leaky fuel situation that MB doesn't want to fix!

Very Nice . I like the .0005 clearance fit. You can Heat it lightly ,150* F and still get it index properly. As usual Nice Job Craig!

Very nice offering.

Thanks Pat, really appreciate that coming from a master like yourself. Did you get my email about all that driveline data I sent you for the track

Except that the crank is larger than the pulley so it wouldn't fit. I have one of those calipers and they aren't too accurate so it's all cool...lol

Just spit on it and push harder. It'll go.

C_DirtyTwo

it works, I've done it.













oh, not with the crank pulley though

Nice nice. Do you also provide straightening and welding services to go with it?
Just curious, hope to never find out.

Ronan Mc Cabe

Got to see and feel the new crank first hand this morning, some really nice workmanship, looks just like factory

GT-ER

I'd like to do this if I even get the change to tear down my engine. Looks fantastic.

BI-Performance

When you refer to straightning and welding, we are assuming you are talking about the crank snout PearlPower?

To answer that question, yes when the snout is machined, material can be taken off, and added back to a certain limit. The adding back of material is done so by welding the snout and turning it down, followed by micro polishing the snout, and journals. This process is repeated until the snout circumferance/diameter is within MB factory spec.

So an out of round snout (bent, ovaled) can be fixed, obviously depending on severity

BI-Performance

Still available, $750 plus ship.

IM__FIT e55

My 06 e55 had a 168mm crank pulley installed. The pulley spun and the bolt eventually backed out. Do you guys still have the renewed machined cranks? I'm kind of losing hope with this damn motor. 70k miles on it btw.

Please let me know via pm or email. Cost and all. @ Downtownairnyc@gmail.com
