5.5 Motor Installation: X Motor Adapter Pumps
STEPS
1. To re-use a repaired motor, clean the threads on the shaft of any thread-
sealant residue.
2. Reinstall the pump shaft onto the threaded motor shaft until fully seated.
Rotate the pump shaft to make sure it runs true. Run-out should be less than
0.03 inch (0.76 mm) for every 10 inches of pump shaft length.
3. Loosen the pump shaft from the motor shaft, apply thread sealant to the
threads, and tighten the shaft again until fully seated. Use standard strength
thread sealant on single-phase motors, and a high-strength thread sealant on
three-phase motors.
4. Install the motor adapter onto the motor and install and tighten the four bolts
into the motor.
5. Position the seal holder into the motor adapter, using Vaseline or grease on
the O-ring as a lubricant. Replace the O-ring if damaged.
6. Install a new mechanical seal stationary seat, using Vaseline, grease, or water
as a lubricant on the rubber portion.
7. Install the rotary portion of the mechanical seal using a small amount of
Vaseline lubricant on the round body of the shaft, and also on the face of the
ceramic seat face where the carbon wear ring contacts it.
