MFactory DCT SMFW (6 and 8 bolt)

[Dagumpf]

So I have a N54 E93 DCT (Euro). Had a high rpm misfire issue, so replaced the DMFW with the MFactor SMFW, which solved the misfire issue. All been fine for a few months, and I could live with the chatter noise, but now THIS clunking noise has started, only happens at a very specific rpm around 700rpm. Any thoughts?

Yikes. That has been added to my list of car noises I don't want.

Sounds like you've got some construction work going on.

Any way to put in a scope and look to see if something is coming loose?

Ah shit, now I know where I lost my jackhammer! Tranny coming out for an inspection.

Hope it’s not what @Begood69 had with his mfactory gear

This is how i upgraded. No chatting and swap m8 (12.9 grade) for m10 (18.2 grade) screws. It should hold.

I just ordered one of these a couple days ago for a 335is. So now I have 2 questions after reading this.

- Are those M8 bolts going to be an issue? I'd rather upgrade those right out of the box if there has been failures.
- Looks like putting new stock trans bushings is the way to go if you don't want to incur more noise after install of the SMFW?

Also, anyone who has ordered direct from MFactory, about how long did it take to get to you?

There has also been some posts and videos I have seen where there is mention that if you do not pre-load the center driveshaft bearing, toward the engine, it will cause vibration and noise after you work on the DCT or make changes. Also, I've seen someone complain about a bunch of noise to find out they put that bearing in upside down.

Humm, I did preload the bearing 1/4" twords the engine based on a video I watched. Since then I have had a vibration between 15-25 mph. I have a Guibo (which I thought was the issue) on the way as well as a new center bearing. I guess it would be good to find out if it needs pre-load.

Anyone know what the torque is supposed to be for the bolts that attach the flange to the FW? This came with zero instructions.
