Hi,
I am wondering if anyone else has solved an issue I have with the rear rub/drum/wheel fixing??
When competing in sevens there is often a requirement for using washers to prevent wheel loss due to pulling over the standard conical nuts. From my assessment of the standard configuration this it would seem that actually the conical nuts do multiple jobs (maybe why they can fail dramatically when highly stressed).
1) They hold the wheel to the drum
2) The cone on the inside of the nut also acts to hold the drum radially centered on the wheel stud (so that torque is not only transferred by the drum screws)
3) Finally the tip of the cone also reaches into the hub outer where the hole is also a larger diameter than the stud so allowing some movement when loose, locating the back of the hub to the front and the drum.
This means that with my tuned engine I am currently eating my way through drum retaining screws and probabaly will eventually have a failure due to this?
Cheers
David
