The collar ring is held in position on the motor shaft with set screws. These set screws
must be tightened to the proper torque to ensure that the collar does not slip as a result
of pump rotor weight and pump hydraulic thrust.
Place a small amount of Loctite 222MS on each setscrew before installing them into the
motor collar.
Table 1: Collar setting distance
This table describes the collar setting distance, set screw size, and set screw torque for TC
and IEC motors.
