POWER LOCK INSTALLATION, REMOVAL & REUSABILITY
Installation
1. Verify that the saft and the inner surface of the hub are clean and lightly oiled.
2. Remove the bolths and clean all contact surfaces. Lightly coat the bolts including their surfaces
with oil or grease.
3. Tighten the bolts part way, and then preliminarily assemble the product.
Note: Pre-assemble by keeping the phases
of the slit and the traps for removal out of
synch.
4. Mount the hub on the shaft, and then lightly push the "Power-lock" shaft-hub locking device to
the end of the hub. When the hub does not smoothly slide onto the shaft, eithter loosen the bolts
or lightly tap on the hub until it is fixed into place.
Note: Do not hit the product with a hammer. This will severely damage the product and possibly
lead to accidents.
5. Determine the position of the hub along the shaft circumference and length. Using a torque
wrench, tighten one bolt to approximately quarter of the specified torque M
and then tighten the one diagonally across in the same manner. Repeat for the other bolts.
6. Using the torque wrench, tighten the bolts to one-half the specified torque M
tightening procedure in step 5.
7. Bring up to full tightening torque M
8. Tighten each bolt to full torque M
completely tightened.
Notes: A torque wrench must be used to tighten the locking bolts. Be sure to follow
the above instructions to tighten the bolts to the specified torque. Hand-tightening or
tightening with wrench other than a torque wrench result in incomplete installation, and lead
to accidents.
