AT THE TRACK
WHEEL NUT TIGHTENING
5.5
Retaining pin maintenance
•
It’s likely that the wheel nut retaining
mechanism will require periodic
maintenance. As part of general event
preparation, inspection should be made
to ensure that the locking pins operate
freely. As required, the mechanism
should be stripped and cleaned
removing any burrs on the pins which
may be present.
Wheel rim maintenance
•
New wheel rims need to be bedded in, in
a similar fashion to new wheel nuts.
Inspection should be made to ensure
that a clear witness mark can be seen,
around the full circumference of wheel
rim/nut contact surface. Ensure the
surface is lubricated with Molykote spray
(see above) during bedding.
•
The mounting face on the inside of the
wheel rims should be inspected to
ensure that it remains flat.
• Should the wheel be prevented from
sitting flat onto the brake disc bell, the
wheel will not remain tight once the car
runs on track.
Wheel gun maintenance
•
Between events it’s recommended that
wheel guns are maintained correctly.
• It is important that wheel guns are
regularly checked against a calibrated
torque wrench to ensure that the
correct clamp load is being achieved.
