Check your Nuts.....

[Graham]

Like most men i regularly check my nuts, you know the big ones at the back that hold the rear wheel hubs on.

In fact as its a race car they get checked after every meeting, and they are drilled and have a split pin fitted.

So imagine the senario after a very fraught second race at Anglesey on sunday when I walk around the car in parc ferme to discover the n/s nut is only held on by 2 turns that will explain the interesting handling then!!!


So just for my piece of mind chaps if you wouldnt all mind checking your nuts.....


p.s.

the spooky thing is on the way there we almost got collected on the motorway by a car avoiding a transit that had just lost a wheel

those split pins can be a bit misleading. I checked mine once, and the split pin just fell away as I touched it. The bolt had sheared it, though it looked like it was still held in place. I had to get a man with a very big pole (ooh errr!) to tighten it up properly for me. I now rely on a paint mark to keep an eye on it.

Apparently TVR saved a whole 60p per car by not having the fecking nuts handed !!!!



Cheers Guys...

Graham, I assume it was the N/S nut that came loose?
Any idea what happened to the split pin?
Interested because my N/S nut is drilled and pinned and I thought I was safe!!
Torquing your nuts to 250lbft......now that would make your eyes water!!

Yep N/s Nut. the pin must have sheared and fallen out.

The best solution seems to be pinned, locktighted and a paint mark across to visually spot movement.

The car gets a full nut and bolt check after every run as it does tend to shake its self apart!!!!! and we still missed it, so what its like on a road car that might get checked once a year i hate to think..

Pinning is fine but the fit must be precise so as not to eventually shear. Better to use a taper pin but this requires a tapered reamer to do it.
