Checking and suppressing the residual unbal-
ance of the clamping means
In order to ensure good balance quality the residual
unbalance of the clamping means should not ex-
ceed 5 g if no wheel is clamped.
• Carry out a check run without wheel: Fully open out
the two driver segments (Fig. 12, Item 4) until the
pins engage; make sure they reach both the end
position!
Inputs to be entered for the check run:
– vehicle type: car
– distance: 200 mm
– diameter: 15"
– width: 3.5"
If the unbalance reading is 5 g or more, we recom-
mend that the adaptor unbalance be compensated
for in a compensation run.
Clamping motorcycle wheels
Refer to Figure 12.
• Open out the two driver segments (4) until they
engage. The wheel is driven by means of these
two segments.
• Push the wheel onto the centring cone of the
adaptor arbor, then push the counter cone (1) and
the distance sleeve (2) onto the arbor and tighten
with the clamping nut (3).
• Pull the locking bolt (5a) to disengage the driver
segment (4a), then move the segment slowly
inwards and fi t it on the tyre.
• Repeat the same action for driver segment in
position (4b).
Motorcycles centring sleeves
Different centring sleeves (Fig 12a, Item 1) can
be supplied for motorcycle wheels on which the
bearings are shielded by gaskets so that centring of
the wheel is impossible by the cones of the adaptor.
Delivery of all motorcycle wheel adaptors comprises
two centring sleeves having an outside diameter
of 17mm, two centring sleeves of 20 mm outside
diameter and two centring sleeves of 25 mm outside
diameter (for BMW).
For further special clamping means (e.g. for mono-
lever wheels) see the Accessory Price List.
