1. Disassemble the coupling:
a) Check that all components are clean and no foreign matter is lodged in any of the machined
recesses or registers.
b) Insert the driver key into the drive shaft keyway and slide the driver hub onto the drive shaft.
c) Position the hub so that the threaded shaft end is exposed enough to allow for the mounting of
threaded sleeves on the shaft end.
To ease the assembly, you can temporarily secure the hub in this position using tape or a rope.
d) Screw the threaded ring onto the driver shaft until the ring extends beyond the shaft end between
0.06 in. and 0.09 in. (1.52 mm and 2.29 mm).
This ensures that the driver and pumpshaft ends will not contact each other when the coupling is
completely assembled.
2. Insert the pump key into the pumpshaft keyway and slide the pump hub onto the pumpshaft.
Position the hub so that the threaded shaft end is exposed.
3. Screw the threaded ring onto the pumpshaft until the ring extends beyond the shaft end between 0.06
in. and 0.09 in. (1.52 mm and 2.29 mm).
4. Slide the pump hub towards the threaded ring until the threaded ring is fully seated in its register in
the hub.
