6.Slide the liquid end assembly off of the pump shaft, taking care not to bend the pump shaft.

7.Remove the retaining ring and remove. The rotary head of the mechanical seal.

8.Remove the seal holder along with the stationary seal seat.

9.Remove the four (4) 3/8-16NC bolts that hold the motor adapter to the motor, and remove the motor adapter.

10.Remove the pump shaft assembly where it is screwed to the threaded motor shaft by first heating the joint area to loosen the thread-locking compound. Secure the motor shaft using a vise grip, and loosen the pump shaft assem- bly. An impeller may be used to grip the shaft, taking proper care not to dam- age the impeller. Or, use a vise grip and fabric rug to grip the splined shaft, taking care not to damage the splines.

11.The motor can now be serviced by a qualified service center, or replaced.

5.5Motor 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.
