4. Centring of the wheel with centring rings for specific vehicle
models from the back of the wheel, and securing with clamping cover
and toggle nut from the front of the wheel:
Select the correct centring ring (it must enter the machined centre hole
on the wheel exactly) and push it over the flange shaft. Carefully push
the centre hole of the wheel over the centring ring and at the same
time press the clamping cover over the flange shaft and against the
wheel. Tighten the toggle nut by hand to secure the wheel (see Fig. 4).
Do not use any tool such as a hammer.
5. Centring and securing the wheel with centring discs and a quick-
clamping ring nut from the front of the wheel:
Motor-vehicle wheels which do not have a machined centre hole can
be centred and secured with centring discs supplied for specific models.
Hold the wheel against the flange contact face and push the correct
centring disc over the flange shaft (with the centring pin leading) into
the attachment holes on the wheel. Tighten the toggle nut by hand to
secure the wheel (see Fig. 5). Do not use any tool such as a hammer.
6. Centring and securing the wheel with centring cones and a togg-
le nut from the front of the wheel:
This version is seldom needed. It is for wheels with low wall thickness
in the machined centre hole area. Hold the wheel against the flange
contact face and push a suitable centring cone (which must enter the
middle-centring hole on the wheel) over the flange shaft and into the
middle-centring hole. Tighten the wheel by hand with the toggle nut
(see Fig. 6). Do not use any tool such as a hammer.
