STEP 1
7.1. Clean dirt and burrs from shafts and hub bores.
7.2. Be sure the keys fit shafts properly.
7.3. Position both hubs on the shaft without tightening the
setscrews.
7.4. Use a half element to set proper hub spacing.
7.5. When the hubs are properly spaced, tighten
the setscrews.
7.6. When using tapered bushings, follow bushing
manufacturer’s instructions.
STEP 2
7.7. Mount first half element to the hubs using cap screws
provided.
7.8. Rotate the shaft 180 degrees and secure second half
element.
7.9. If shaft cannot be rotated, mount half elements at 90
degrees.
STEP 3
7.10. Tighten all cap screws to the torques specified in Table
3.
7.11. Align equipment.
7.12. Install proper guarding prior to equipment start-up.
