3. Apply light oil or grease film to both sides of the hardened steel washer. This is very important, since
it will significantly reduce the rubber stresses around the metal bushings when torquing down the cap
screws. Place the supplied hardened washers under the cap screw heads and torque the screws
down to the torque rating in the assembly instructions supplied with the coupling. Keep the surfaces
between the steel bushing in the elastomeric element, the hardened washer and the cap screw head
free from dirt.
4. Check to see if element is centered between shaft ends. If element is centered, using the loctite
supplied with the coupling, lock all set screws (must have loctite, supplied with the coupling, applied
to set screws) to 50 ft-lbs. If element is not centered, unlock the set screws and slide coupling to
center element between shaft ends and then, using the loctite supplied with the coupling, lock all set
screws to 50 ft-lbs.
Rotating machinery can cause personal injury or death. Do not operate unit
with either the coupling guard or the collar removed. All bolts and screws must
be properly tightened.
