Official Thread: Report Here if you Spun your Crank Timing Gear Hub.

[kitesurfer]

Guys,

I'm sure you have seen the scary post from a vendor about a potential weak link in the S55 which has to do with the timing chain HUB on the crank shaft. If not here is the thread:
http://f80.bimmerpost.com/forums/sho....php?t=1163531

The vendor makes it seem as though this is a prevalent issue with Tuned and higher power cars and may even occur in stock vehicles.

I'm sure forum members would like to know how real of an issue this may be and if its happened to any forum members. Please report here if you have experienced this issue with you car

[Mandi90TT]

Yeah, I'd like to see if anyone has had this happen to them, as well (other than vendors). Given the high labor time (6-8 hours, I think) to install this fix, it's not an easy decision

[rr006rbc]

I'm not entirely sure it's a known and common enough failure to warrant the repair. Honesty it could lead to premature failure of other items while performing this repair. The only time I've seen this happen is when a 6MT M4 hit about 11k RPM on a wrong shift from 5th to 2nd.

This is not some made up issue, as you start to see more modified cars you will see this arise more often. This piece is designed as a preventative maintenance, if you choose not to, totally your choice, what we have done is recognized an issue based on our own experience, and that of others we have worked closely with, and created a solution for it.

If anyone has any questions regarding this topic feel free to ask I will do my best to address them.

We appreciate you post however this is much the same information you have posted in you thread offering an aftermarket crank hub part for sale...... The purpose of this thread is not to debate weather or not this an issue ... but rather a place for forum members who have experienced this problem first hand to come forward and report it to share with the community.
So Far there have been ZERO reports of this problem....lets see if that changes

Yup! you're right.

[JasonTPG]

Both DCT and 6-speed

[Warranty P]

So still ZERO reported cases? Looks like nothing to worry about.

[AustinY 2208]

In my opinion don’t worry about it because Engineers think very well before they design such engine. We think to much, just enjoy
and drive.

What about the engineers that designed the S65?

[Racer20]

Check the other thread. Someone just reported it happening to a JB4 stage 1 car. It could also be the cause of all the "drivetrain malfunctions" that have popped up with no clear root cause.

Read the entire thread and you'll see that all the tuners on the forum have reported multiple instances of it in that thread as well.

The Forum Member you mention in the other thread is alexontwowheels his car is at the dealer being diagnosed at this point he "thought" if may be the timing hub issue. I had already asked him to report in this thread if that turns out to be the case.
So as it stands currently ZERO direct reports from forum members.
From what I have seen Most All of the Drivetrain Malfunctions reported by Members in other threads have been due to Over Rev / Money Shifts

[AustinY 2208]

No report?

[BuLoOoSki]

Well, I have to say I'm glad that there are no reports. I particularly started to worry when TPG claimed that this seems to be an issue regardless of whether you are modified or not.

Interesting development indeed...

[Alexschmalex]

Hey all, as Kitesurfer mentioned, I believe this happened on my M4. I hit a hard downshift from 3rd to 2nd, the car went into limp mode with the motor still running. I parked it on the side of the highway, shut it off, and it wouldn't restart. It went to the dealer and they reported the timing had spun off nearly 180 degrees. I found the other thread that has now been disabled (weird!). I also talked to the guys at Pure Turbo's that had the same thing happen, they got the repair done under warranty.

The shop is about to do the work to re-time the motor and I would actually like to install that preventative measure when they do it. BUT, with that post going down, and the very good point that with this in place something else major could fail, I'm actually wondering if I should just keep it stock.

I'd really appreciate anyones insights and thoughts on this.

Not that odd, seeing they do not appear to be a site sponsor.

Did you overrev the motor on the downshift any report of that from the dealer? I assume the work is being performed by a dealership are they covering under warranty?

If there was no over-rev and you infact did spin the crank-timing-hub....I would definatley see about getting the part installed the company who makes it is TPG Tuning out of PA

[Bowser330]

What does "hit a hard downshift" mean? Over rev?

Simple - they posted a thread about a product they sell, and they are not site sponsors.
