Tightening
up the sleeved wheel nuts on a Dunlop composite wheel on an
MGBGTV8
Following a recent query from a V8 enthusiast on how best to
tighten up the sleeved wheel nuts on a Factory MGBGTV8 fitted
with the original Dunlop composite wheels, Victor Smith highlights
it is well worth drawing attention to a standard routine V8
enthusiasts have used for many years.
(Aug 2012)
The wheel nuts used with the Factory fitted Dunlop composite
wheels (alloy centres with chromed steel rims) are a sleeved
nut. Unlike the conical faced wheel nuts used with the standard
wheels fitted to the MGB models, the sleeved V8 wheel nuts do
not self centre when a Dunlop composite wheel is offered up
to the studs and the nuts tightened up. It is poor design feature
which can result in the wheels being slightly misalinged on
the studs leading to wheel balance problems.
So when refitting a Dunlop composite road wheel it is necessary
to centre the wheel on the studs using of two standard MGB conical
seating wheel nuts acting as slave nuts on opposite wheel
studs before tightening up two sleeved V8 wheel nuts on the
other two studs. As the conical seating of the wheel nut presses
onto the outer face of the stud hole in the wheel, it has the
action of centreing the V8 wheel on the studs. Once the
two V8 sleeved wheel nuts are on and tightened up, then you
undo the two slave nuts and replace them with the other two
V8 sleeved wheel nuts. They are tightened to the recommended
torque of 60 lbf ft.
You can get hold of a pair of conical seating wheel nuts very
easily – they are the type used on the standard MGB 1800
model, part number BHH1087.
If you have your wheels removed by a tyre fitter or by a garage
mechanic who is not an MG specialist familiar with the V8 model,
then
you will need to ensure the standard routine above is followed.

2003 on avoiding wheel nut damage. He has some good advice on
how to avoid damage to the chrome wheel nuts on a V8 by using
a Wall Drive Socket, sometimes called a Flank or Surface
Drive, which exerts pressure on the flats of the wheel nut instead
of the easily damaged corners. V8NOTE291 |
