Standard ALU programmes (ALU 1, 2, 3, 4, 5)
The standard ALU programmes allow for the various modes of application of the weights
(Fig. 15) and supply correct unbalance values maintaining the settings of the rated geo-
metric alloy wheel data.
- Press the
illuminates.
- Press the
programme desired (the corresponding balancing planes are highlighted on the rim
shown on the display).
- Set the rated geometric data.
If the values of the diameter and of the distance between the balancing planes, recalcu-
lated on a statistical basis starting from the rated geometric data of the wheel, exceed
the normally accepted interval stated in the TECHNICAL DATA section, the "A Alu" mes-
sage is displayed.
- Proceed as described for dynamic balancing.
- For the application of the balancing weights, refer to the paragraph "SELECTION OF
ADHESIVE WEIGHTS APPLICATION POSITION".
IMPORTANT: in ALU1 and ALU2 programmes the unbalance displayed by the machine
on the outer side refers to the adhesive weight centre of gravity at the shaft assembly
bearing flange, see figure 16e.
Some slight residual unbalances may remain at the end of the test spin due to the
considerable difference in shape that may be found on rims having the same rated di-
mensions. Therefore modify the value and position the previously applied weights for
accurate wheel balancing.
Motorcycle wheels can be balanced in:
- Dynamic mode; when the wheel width is such (over 3 inches) to generate significant
unbalance components which cannot be eliminated with static balancing (the recom-
mended procedure).
