CARRIAGE" section, taking care that the central hole of the rim is mated correctly
with the step flange.
- secure the wheel on the flange, placing the clamps on the edge of the rim
correctly and fully tightening the screws which fix the clamps to the flange arms.
Note
Considering the coupling inaccuracies of this type of rim, it is essential to centre
the wheel on the flange with the greatest care to obtain good results.
The following parts are available:
- medium-sized two-sided cone for centring wheels with central hole:
• from Ø 160 to Ø 176 mm on small side;
• from Ø 200 to Ø 202 mm on large side;
- large two-sided cone for centring wheels with central hole:
• from Ø 220 to Ø 222 mm on small side;
• Ø 281 mm on large side;
- two-sided spacer for use with the cones above.
The procedure for centring a wheel using the parts described above must be
carried out as follows:
- fit the spacer on the balancing machine so that the smaller side is on the outside
if using the medium-sized cone, or the larger side on the outside if using the large
cone;
- fix the spacer to the flange of the balancing machine using the two screws
provided;
- fit the wheel on the balancing machine shaft as described in the USING THE LIFT
CARRIAGE section. Do not lower the lift!
- Then fit the cone on the shaft with the side suitable for the diameter of the rim
hole facing towards the rim itself;
- fit the ring-nut and tighten firmly to lock the wheel effectively in place;
- lower the lift.
Note
For accurate centring using the cones; it is of vital importance that the rim's central
hole is not misshapen!
The cones are used to balance the wheels of vans and off-road vehicles and car
wheels having central hole with diameter larger than that of the shaft (46 mm). The
following parts are available:
- single small cone for centring wheels with central hole from Ø 47.5 to Ø 64mm;
- medium-sized two-sided cone for centring wheels with central hole from Ø 60 to
Ø 115mm;
