Hidden spoke placement
9.3 Correction of measured unbalance
•
Press the START key.
The measuring run is carried out.
During measurement one middle segment is read out on each
of the digital displays
(Fig. 58)
.
After measurement the machine stops automatically, the wheel
is braked down to standstill and the display is as shown in
Fig. 59
.
This shows the unbalance measured in each correction plane
and the direction towards the correction position on the direc-
tion indicator.
How to fit adhesive weights on the left side of the rim disc
•
Clean the wheel before attaching the adhesive weights.
•
Fit adhesive weights on the left side of the rim as de-
scribed in § 8.2.
How to fit a hidden adhesive weight
•
Rotate the wheel so that a spoke is at 12:00 o’clock
(Fig. 60, arrow)
.
•
In this position press the key for balancing mode
(Fig. 56, item 1).
The divided amount of unbalance of the behind-the-
spokes placement is read out for the first adhesive
weight in the right correction plane
(Fig. 61)
; in the
example 15 g.
Note
The small arrow on the left-hand side in
Fig. 61
indicates the
shortest way to index the position of the other adhesive weight.
•
Index the wheel to the exact position for correction in the
first correction position and hold the wheel in this posi
-
tion with the main shaft lock.
•
Clean the wheel before attaching the adhesive weights.
•
Attach a weight in the position (in the example 15 g,
Fig. 61
).
The divided amount of unbalance of the behind-the-
spokes placement is read out for the second adhesive
weight in the right correction plane
(Fig. 62)
; in the
example 5 g.
•
Fit the second weight behind the spoke in the same way.
To return to the undivided reading of unbalance for left and
right correction plane (Fig. 59):
•
Briefly press the key for balancing mode (Fig. 56, item
1). The unbalances for left and right correction plane
are read out. The behind-the-spokes placement mode
is still active as long as Alu 2, Alu 2P, Alu 3 or Alu 3P
are set.
To leave the behind-the-spokes placement mode and reset
the electronic unit to the conventional balancing mode:
•
Press and hold the key for balancing mode. Rotate the
wheel to set a balancing mode other than Alu 2, Alu 2P
or Alu 3, Alu 3P.
or
•
In the reading “Wheel data” press twice the key for bal-
ancing mode and set number of spokes to 0.
