WHEEL NUT TIGHTENING
Wheel Nut Care
It is the teams’ responsibility to ensure all pit
equipment used for wheel nut tightening is
correctly set to achieve the correct wheel nut
tightening torque. Wheel gun air pressure and
“gun on” time is also critical to this.
McLaren recommend the use of a Dino Paoli
DP 4000 MG UH wheel gun (available from
McLaren) set at a regulator pressure of 20 bar.
Wheel nut tightening
•
Wheel nut torque should be checked pre
session once the wheels are gunned in
place.
•
Wheel Seating – Care must be taken that
the wheel is seated squarely when
gunned up. An incorrectly seated wheel
is likely to quickly come loose once the
car begins to drive.
Lubrication
McLaren GT recommend that Dow Corning
Molykote 1000 spray
(www.lubricantsupplies.co.uk/molykote-
1000-spray-x-400ml-box-of-12.html) is
applied to the following parts, as part of
general race preparation:
•
Stub axle threads
•
Wheel nut threads
•
Wheel nut mating face
NOTE: Care must be taken to ensure that
Molykote spray does not reach brake
pads or discs.
Wheel and wheel nut bedding procedure
•
New wheels and wheel nuts should be
bedded using a wheel gun, tightening
and loosening the nut 15 - 20 times,
following which inspection should be
made to ensure a clear mating face, with
a good contact area has been achieved.
•
For the bedding procedure, ensure that
all areas covered above have been
adequately lubricated with Molykote
spray.
Drive peg maintenance
•
It is imperative that the condition of the
drive pegs in the wheels need to be
regularly inspected for any burrs or
damage.
