1. Rough Alignment
• Vertical: Place scale or straightedge on highest hub and
raise or lower the movable shaft to within 0,5 mm of the
stationary hub.
• Horizontal: Place scale or straightedge on hub nearest to
you and adjust the movable shaft to within 0,5 mm
of the stationary hub.
2. Correct Obvious Soft Foot
Loosen all the bolts and nd any obviously loose shim packs.
Add shims as needed to make a snug t.
3. Follow Tightening Sequence
Follow the same sequence throughout the alignment
process, and tighten in 3 passes: snug rst, 50% on second
pass, completely tight on the third pass. (View sequence on
next page)

4. Make a Final Soft Foot Correction
Loosen one bolt at a time and check for soft foot with a
0,05 mm shim or feeler gauge. Correct any foot with 0,05
mm or more of soft foot, then tighten the bolt before
proceeding to the next foot.

indicate the direction of adjustment.
5. Continue to adjust the movable machine, watching
the live readings, until both the angle and offset are
within tolerance.
6. Tighten the bolts using the tightening sequence
established in Pre-Alignment.
7. Some machines move laterally when tightening the
bolts. Make sure that the displayed values remain in
tolerance as you tighten the bolts.
