One thing you might have to be careful with high tensile bolts is that they might break with expansion?? Just a point...

M10 x 50mm x 1.5mm pitch. Some inconel bolts would be the go.

Lockwiring would help, but the nature of the beast is 1/8th of a turn to loosen its start. Also the location is, lts say, not really friendly to being able to get lockwire secured in there. i would be all for that too...

Jimmy, a group buy might be on

Yes, I was going to say the biggest problem with wiring is not the drilling, or the wire...it's the #@$&g location of the bolts! Definitely requires evolution of the species to produce a primate with opposable thumbs and wrists!

Maybe the method should be tested with Dave and Guy, at least initially, to see if it goes the distance long-term?

We have 6 solid hours on the track tomorrow in the polo so we will see how our new bolts hold up

[PeterHBne]

Which track?

well at least you can justify thrashing the living bejesus out of it tomorrow - all for a worthy cause - R&D

Shouldnt this problem be vw's problem?

And they do a full recall and replace them all....

[Jmac]

Yes they do but they still come loose mate!
Im trying to source some aircraft bolts at the moment. As i mentioned back in the piece we had the same thing in th 90s with turbo diesel Audis . There is som much expansion and contraction happening there. I know not an excuse as i dont think it happen to other makes, although i heard recently a customer had there xr6 ute turbo come loose!!!
Go figure. Gotta b a way

Hey Guy - what time? (i doubt you'll be in here this morn.....)

I might trot out for a look.

[DaveMack]

OK ... I'm pleased (& somewhat embarrassed ) to report that it is NOT my turbo making these horrible noises ... it's my aircon. Jimmymac had a look at it today and we went out for a test run. He says probably the "TX" valve or the compressor ... but at least it's not my turbo.

I'll still happily coordinate our documentation of loose turbo bolts and see what we can do about these in the long term ... so if anyone else out there is having these problems ... please post to this thread.

Cheers,
Dave

Firstly great to have met you Dave and dont be embarrassed about that noise mate, it is a scary noise if u havent heard it before. Anyway i have another idea about locking the bolts. What about a tab washer between the bolts??? This was an effective way of locking back in the day and we all know the oldies are the goodies!!! Meanwhile i have emailed my old foreman mate at Boeing to source some hight temp bolts!!!!
Keep yas posted!
