Crank Hub Spun On New Bedplate Design

CloudVIII · 09-07-2017, 11:26 PM

I wanted to inform the community I have had a crank hub spin on new bedplate design.

Initial failure was a full engine replacement by dealer in June with the new bedplate design. (JB4 only)

This time new engine crank hub slipped and timing jumped 60 degrees. (Pic attached) It happened while on the dyno (570hp/638tq) in August.
Mods this time were JB4, DP, Meth and drop in filters.

To reset timing cost me $6k for parts and labour including exhaust vanos failure and install of Vargas Crank Bolt Capture. (Testing this now with Pure Stage 2 turbos)

I am a sucker for punishment.

Additional car details are F80 August 2015 build, DCT, May 2017 New Bedplate design Engine.

Bedplate redesign may have helped but is not the solution.

I thought the new bedplate design did not happen until Dec 2015 Builds?

If yours is August 2015 , then it is not the new bedplate design.

I had the new engine with the new bedplate design installed in June.

Did they tell you how it spun? Did the bolt back out?

They believe the friction disk slipped. No idea for sure though.

Dang. Sorry to hear that.
Even with the new bed plate design.
My front hub has spun twice. New friction disc update but with original bedplate design.
My local shop recently received their clients F10 M5 engine built from Steve Dinan's new shop SD AutoTech.
My repair shop is currently removing my S55 engine to send to Steve Dinan for full build. They are keying the crank and upgrading pistons, connecting rods, cams, etc.

Cost? That definitely sounds like the better option for someone who is facing factory rebuild costs

There are various options.
I can not disclose that at this time but he has a website with their contact information.

anyone seen a 6mt car with the new bedplate spin?

apexit · 09-27-2017, 02:46 PM

Possible that they used an older bedplate engine when they replaced yours?

Nope it has the bedplate long block part number.

The 6-spds rarely ever spun their crank hubs without it being because of a miss shift and massive overrev. I think out of literally thousand upon thousands of M3/4's their been ONE verified case of a none money shifted 6-spd crank hub failure. And zero failures at stock power level with no misshift so I doubt you'll ever hear of the new bedplate design in 6-spd failing. ps: VTT already has a solution that hasn't failed for this yet. Same with maximum PSI, and TPG...

Are you referring to my old 02/16 MT M4?

Sadly and reluctantly I honestly wouldn't feel safe with any S55 at this point as I feel like its only a matter of time...

Yes, yours and a highly modded upgraded turbo car too. Regardless thou, no need for that sad attitude! We have *several* very promising and affordable solutions to that problem that have been holding up fine at 700+whp now..

parabmw · 10-01-2017, 12:45 PM

If this was so pervasive why wouldnt bmw fix it by now? Especially if the fix was relatively cheap.
The warranty claims as well as public image would become an issue.

Because it's not pervasive at all on stock or even near-stock engines?

hdubf80 · 10-05-2017, 12:41 AM

Will BMW ever put out a recall for this issue? This has been going on long enough and a class action suit needs to be brought up against them IMO.

There have been very few cases actually confirmed on here. Why do you think BMW needs to recall vehicles

This. It seems this really only happens on tuned cars. Part of the reason I'm not running BM3 right now. It's just not worth the hassle for 75HP and TQ.

I ran stage 1 JB4 for the alpha testing back when the car first came out for almost 20k miles. I'm talking routine 150mph pulls near daily over that time frame. Sounds like luck of the draw I guess
