Carbpn Fibre Tailshaft Balancing

[some_cs_student]

Hi,

So I've installed a carbon fibre tailshaft and it appears to be not balanced correctly.

The vibration occurs at anything over 80km/h and then gets worse, 100km/h is not very drivable

It is an ACPT shaft and was not part of the group buy.

The seller is offering some assistance as the shaft was checked and supposedly ok before I received it.

RE Customs installed the shaft.

Is there anything obvious that could go wrong in the install? From what I can see you just bolt it in...

Also, does anyone know where I can get the shaft balanced in Victoria?

Thanks,

Gareth

I take it you've read the ACPT thread (GB section)

There were a few places in there i think that did it.

End of the day though, they were not repairable I think...

Hope you get it sorted dude...

Yes, that is what worries me

I have now read the thread and finally the seller has replied to me. He did get it checked in Adeleide and they advised it was balanced, so I'm getting RE Customs to take another look on Tuesday at it, and check the balance if possible. The seller has offerred to look at the quote for getting it re-balanced. RE did have some issues with 4 bolts been two long, so I'm hoping it's a minor install issue or something a tiny bit out and it can be fixed.

On the positive side the driveline clunk / sound my skyline always had is gone and the acceleration is smooth, until I hit 80km/h

Also I appeared to have spelt carbon incorrectly while at work (too much multi-tasking)

Futher research shows that the picture of the shaft is from the group buy, its in fact the same image sly33 had when he bought the shaft. I haven't checked the serial numbers to confirm if its the same shaft yet. RE Customs will confirm if the balance can be fixed or not, I did notice one person did manage to get it fixed so I can only hope I can get it balanced and working.

Or that the modifications RE Customs had to do to the bolts to get it in went wrong, which is unlikely.

Confirmed to be a group buy shaft, serial numbers match with Sly33's shaft. I'll do another test drive today and take it to RE customs on Tuesday.

So....where did you purchase it from?

curious if this one shaft has been floating around for 2 years with no-one able to get it to work?

I hope not!

kn6gtr who appears to have bought it from Sly33. It was claimed to be brand new and it appeared to be completely unused. In fact it would make sense that it was never used if the mechanic had to cut the bolts because they were too long to fit!

At this stage I'm going to ask RE customs to get it balanced and just hope it works, I'll update the thread on Tuesday evening.

Shaft is not fixable, now attempting to organise a refund with the seller.

that was sort of my impression from the group buy way back - sorry to hear

Yes, I wouldn't have bought it if I knew it was from the group buy. Seller did say he will provide a refund but I'm waiting for the money to actually be in my bank account.

Until then I'll be checking for progress updates with him pretty soon
