HELP! - New Clutch fitted but NOT disengaging!
Discussion
I'm well hacked off and only effectively have 24 hours to sort this, or I may be returning to the UK in a boring car at the end of this week - so any help would be much appreciated.
Received new uprated Helix clutch and uprated slave to fit. First problem though was we discovered the supplier did not include the alignment tool that was meant to be included
Managed to eventually align things but without the tool we were unable to check it by pressing the clutch to see if the tool would spin, before inserting the gearbox. We therefore assumed it was all ok and put everything back.
HOWEVER one can select gears when the engine is not running (with or without the clutch depressed) but when engine is running cannot select any gear. The clutch is not disengaging.
I will ring Helix tomorrow to see if it is possible we organised plates incorrectly that would cause this (this is my first assumption since we had them in and out so many times trying to align them), but otherwise has anybody got any other ideas????
Bled a good 1.5litres through the system until there were no air bubbles.
The pedal feels great. Great rebound and a good feel depressing it.
There are no leaks anywhere on the system.
Thanks in advance for any experiences that might help me, Regards, John.

Session - thanks so much for your email. Have just finished on the phone with Helix and I strongly suspect that my clutch maybe from the same batch as yours. Am going to dismantle it and if on measuring the thickness of the plates they are over-spec then I too will be in the same boat as you. Hopefully it is something else but my instinct tells me not.
I too wanted to be at Millbrook with the car, leaving from France this Friday. If it is an out if spec clutch I will try fitting the old one again (since it was the slave that was the real problem), but it means the whole operation will then need to be done again once I have a corrected clutch!
Are you still going to be at Millbrook, in another car? If so and I am there we can have a rant together!

I can unfortunately confirm that my instinct was right. Following receiving the disc thicknesses spec, direct from Helix, and taking everything apart for a SECOND time I measured the discs and they are out of spec - simply too thick - no way they were going to disengage!
I've been "lucky" enough to be able to put back my old clutch in order to be able to get from France to the TVR meet this weekend since the new slave works fine and that was the key problem that needed fixing. That's hardly the point though as I will have to have all the work re-done for a 3rd time when TVR send me a working clutch!
My order was a disaster from the word go. More than one piece missing (including the lack of alignment tool which alone cost my mechanic a lot of time - twice!), one ARB bush sent instead of two - who at the end of the day would want one?!, exhaust bolts that were too short, and to finish off a clutch which is way out of spec. Thank christ the slave was 1) sent and 2) worked!
Thanks again to Session who pointed me in the right direction and my heart goes out to you because I know what this big meet at Millbrook means to lots of enthusiasts like me and him.
If anyone else has recently bought a Helix clutch from TVR parts and has not yet fitted. DON'T!! First find out if it is in spec. TVR ought to be contacting clients immediately that they have sold these to since there is known problem - I'd be interested to know if they are because ether sure as hell told me nothing yesterday when I called them to complain about the fact that they have forgotten to include the alignment tool.
Contact me if you need specs of what the discs should measure.

Sorry to hear of your continued woes JorEi. I have not yet had any satisfactory resolution of compensation either, so far, although positive noises are being made. I don't see why any of us should need to get into a conversation with Helix about compensation - we all bought them from TVR Parts - it is their problem to resolve.
I'm gutted to hear that your new thinner plates are not disengaging. I too was told by TVR Parts to hang on to the assembly and just send back the plates, so this is very concerning that they might have now tinkered with the assembly too. It is TVR Parts' responsibility to find out exactly what is going on and be up-front and honest with us all. I'm certain there is more to this than just that the plates were made too thick. It has already been said to me by TVR Parts that Helix had redesigned out a previous problem and that in doing so they created this latest problem.
Keep us updated JorEi and good luck.
