9. Tighten the tailstock bearing gland nut to the tailstock adapter shaft per the
bearing manufacture’s literature.
10. Remove the hoisting straps.

Tooling Fixture Installation (regular)
1. Jog the headstock until MotoMount is horizontal. The tooling mounting
holes and locating pin must be pointing up.
WARNING!
Make certain servo power is OFF for the remainder of the
installation, or serious operator injury and/or equipment damage
may result.
2. Use a suitable lifting device to position the tooling above the headstock
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.
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 (.039 in.) after the headstock is rotated 180 degrees. To
check MotoMount’s horizontal alignment, proceed as follows:
1. Jog the positioner until MotoMount is horizontal.
NOTE:
The alignment procedure may be easier if the weld ground cable is removed.
2. Using calipers, measure the alignment gap.
NOTE:
It is important to measure the alignment gap at the same location. This will ensure proper
alignment.
3. Rotate the positioner 180 degrees.
4. Measure the alignment gap at the second position. If the gaps differ by more
than 1 mm (.039 in.), the horizontal alignment must be adjusted. Use the
following procedure to adjust horizontal alignment:
a) Calculate the average gap between the two positions, by adding both
measurements together and dividing by two.
b) Loosen the bearing mounting bolts and move the tailstock bearing hous-
ing towards the direction of the larger gap until the gap is at the average
value.
