NOTE You should have these parts before you start:

procon-bolt-on-56C-assembly

Mount the drive shaft coupling

Make sure motor is electrically disconnected and cannot accidentally turn on.
Mount the half of the coupling for the motor onto the motor shaft and tighten the set screw.
Insert the elastomer piece onto the motor piece.
Mount the half of the coupling for the pump onto
the pump shaft, but do not tighten the set screw
Make sure the coupling slides easily onto the pump
and the motor shaft, do not force it.
Make sure the shaft does not protrude into the
space occupied by the elastomer piece. Series 6 pumps require a shaft key.

Mount the motor adapter

Use four 3/8 inch dia. by 1 inch long bolts (16 threads/inch) and lock washers. Rotate the pump to orient the inlet/outlet ports.
Trial mount the pump onto the motor adapter while engaging the coupling pieces

Check to make sure the coupling is properly engaged

Tighten the set screw on the pump

Check your assembly

The elastomer coupling piece should have about 1/16 inch of play between the two metal pieces. If it does not, repeat steps 1-5 until corrected.

Fasten the pump to the adapter

Use three 1/4 inch dia. by 3/4 inch bolts (20 threads/inch) and lock washers. For series 6 pumps, use two 3/8 inch dia. by 1 inch bolts (16 threads/ inch).

Make sure the motor rotates correctly
