Mount the two hubs with provision for pins on each end of the floating shaft. The hub faces should be flush with the ends of the jackshaft.

Mount the other two hubs on the shafts of the driver and the driven equipment such that after assembly, the gap between metal to metal on each pair of hubs would be between 3/16" to 1/4".

Tighten the setscrews on the hubs.

Press in the Bushings into the holes. Do not use any lubricant.

Position the jackshaft so that the threaded holes of the hubs line up with the bores of the bushings on the opposite hubs.

Apply a few drops of Loctite 242 or equivalent thread locking compound on the threaded portion of the pins and insert them from the back of the hubs torquing them down to 35 ft-lb torque.

Align the driver and driven shafts to specifications provided by the equipment manufacturer. Laser or Dial Indicator alignment is recommended to get the best coupling performance.

Check the setting dimensions again to insure that the metal to metal gap on each side of the floating shaft is between 3/16" to 1/4".

Put the Coupling/Drive shaft guard back in place.

Start unit and check for any unusual sound or vibration.

Take vibration readings and record the same for future reference.
