Tooling Fixture Installation (regular)
1. Jog the headstock until MotoMount is horizontal. The tooling mounting
holes and locating pin must be pointing up.
2. Use a suitable lifting device to position the tooling above the headstock
assembly.
3. Slowly lower one side of the tooling fixture onto the headstock using
the locating pin.
4. Install the M12 tool mounting bolts and washers onto the headstock
(customer-supplied grade 8.8 bolts), and torque the bolts to 76 N•m
(56 lbf-ft).

Final Alignment Check
The MotoMount system helps reduce the load on bearings due to tooling
fixture misalignment with the headstock and tailstock. However, optimum
performance is achieved when the alignment is as close as possible.
Horizontal and vertical misalignment is possible. Both the horizontal and
vertical alignment procedures require the measurement of the same gap
on the MotoMount drive components. A tooling fixture must be installed to
align the system.
4.4.6.1
Horizontal Alignment
Check the horizontal alignment by measuring the gap (see Figure 4-23)
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 check MotoMount’s horizontal alignment, proceed as
follows:
1. Jog the positioner until MotoMount is horizontal.
2. Using calipers, measure the alignment gap.
3. Rotate the positioner 180 degrees.
4. Measure the alignment gap at the second position. If the gaps differ by
more than 1 mm, the horizontal alignment must be adjusted. Use the
following procedure to adjust horizontal alignment:
• Calculate the average gap between the two positions, by adding both
measurements together and dividing by two.
WARNING
Make certain servo power is OFF for the remainder of the installation,
or serious operator injury and/or equipment damage may result.
NOTE
The alignment procedure may be easier if the weld ground
cable is removed.
NOTE
It is important to measure the alignment gap at the same
location. This will ensure proper alignment.
