7. Centring and mounting of light-truck wheel with centring
cones and quick-clamping ring nut from rim front and
wheel spacers from reverse side of rim:
Since offsets of light-truck wheel rims are very large, the
wheel spacer is inserted between the flange mounting sur-
face and the reverse side of the rim.
Centring and mounting are carried out as described under
Item 6 (see Figure 7).
8. Centring with self-adjusting centring spreader sleeves from
the rim back and fastening with clamping cap or pressure
ring and quick-clamping ring nut from rim front:
Optimum centring for all rims with machined centre bore.
Push coil spring over flange shaft.
Push basic sleeve into appropriate spreader sleeve (specific
type for car) and press it onto the flange shaft. The bulge
on the spreader sleeve must be at the front.
Push the centre bore of the wheel rim carefully over the
spreader sleeve and simultaneously press clamping cap or
pressure ring over flange shaft against rim.
Tighten wheel by hand at quick-clamping ring nut.
Do not use tools such as a hammer.
During tightening, the spreader sleeves will always adjust
without play, with the result that tolerances between the
clamping centre shaft and the cylindrically machined rim
centre bore will be absolutely zeroed during centring (see
Figure 8).
