Vertical Alignment
MotoMount must be at a vertical position to check the vertical alignment.
Fig. 4-29: Vertical Position - Drive Bushing on Bottom
The vertical alignment is checked by measuring the gap between the
mounting fixture and mounting block. The measurement of this gap must
not change more than 1 mm after the headstock is rotated 180 degrees.
To align MotoMount vertically, proceed as follows:
1. Jog the positioner to vertical position until the drive bushing is at the
bottom.
2. Using calipers, measure the alignment gap.
3. Rotate the positioner 180 degrees until the drive bushing is at the top.
4. Measure the alignment gap at the second position. If the gaps are
different by more than 1 mm, the vertical alignment must be adjusted.
Use the following procedure:
• Calculate the average gap between the two positions by adding both
measurements together and dividing by two.
• If the first measurement (with drive bushing at the bottom) is
greater
than
the second measurement, the
headstock must be raised
until
the gap is at the average gap value. Raise the headstock by making
equal clockwise turns on the headstock leveling bolts.

NOTE
It is important to measure the alignment gap at the same
location. This will ensure a proper alignment.
