CCW Wheel Leaking Air
My left rear CCW wheel is leaking at the wheel seam. I noticed it at the last minute before leaving for a DE and my shop used a dunk tank to identify the issue was with the wheel not the tire. They tried some silicon which helped somewhat on saturday, but I had to sitch out wheels to run on Sunday.
Anyway..Can any shop rebuild the wheel and fix the issue or should I be looking for a specialty house...who does this stuff?? I'd rather not send it too far since i'd like to have it back and ready for a DE on the 17th.
Thanks
Jeff

Call CCW and talk to them about it, they are very helpful. They shipped me out a new wheel half last year and it was pretty easy to do myself (takes a while with all of the freaking bolts). They'll also do it for you if you want to pay the shipping both ways. I doubt they'd charge you for the actual work.

Darren, does CCW use sealing gaskets (or o-rings)?

Then Jeff it's easy to do. Just take a razor blade and cut out all of the existing silicone sealer and apply new. I use the heavy duty silicone that has some body to it and on my tire machine run a thin bead that I can press deep into the groove. I continue with a wider bead on top of that, and then a final bead smoothed out to a flat finish. You can do it with the wheel bolted to a front hub too. Or if you want to drive to Ambler, I can do it and remount the tire for a nominal fee.

Jeff,
Call CCW and ask them what silicon product to use. Radial Tire uses a rubberised silcon material that they swear by, and I suspect CCS might have a preferred material too. Also ask them for torque spec for the screws. If you are having it done or doing it yourself, you'll need to follow Larry's advice. Might add a step to clean the area with brake clean or other no-residue solvent before resealing them.

It's a little tougher than it seems, but very doable. I painted my centers last year by tearing them all apart. I couldn;t break the silicone bead so i ended up loosening the bolts and having the tire shop do it. Once apart it was a good cleaning, siliconing and reassembling.
I'd call them first just to make sure though.

There is a whole tutorial on doing it on CCW's site. It's pretty much verbatim to Larry's explanation if you don't disassemble the wheel. As long as nothing is bent it isn't hard to do at all. Here is the link, it's 3 short videos..

He was released from hospital today. No broken bones, and no neurological problems. Remarkable really.
The Finn was taken to the Hospital General de Catalunya in Sant Cugat del Valles immediately following the crash, where CT scans confirmed he had no head injuries and no broken bones. He was kept in overnight for observation, but further tests and scans on Monday morning all went positively and showed no problems.
“I have a slight headache and a stiff neck, but apart from that I am feeling well and in good spirits,” said Kovalainen. “My focus is on getting better as soon as possible so I can pass the FIA medical inspection required to allow me to race in Turkey.
“I don’t remember anything from the accident or what happened afterwards but would obviously like to thank all the circuit emergency staff, the FIA medical team at the track and the doctors at the hospital for all their efforts in looking after me. Also thank you for all the messages I have received - they all mean a lot.”
McLaren have established that Kovalainen’s speed was approximately 240km/h when his front-left tyre deflated and about 130km/h when he hit the tyre barrier. He experienced a 27g deceleration. The team suspect a wheel-rim failure was to blame, but have yet to establish the exact cause.
