5.1Motor Bearing Lubrication

Motors up to 3 Hp typically have sealed bearings. Motors of 5, 7.5, and 10 Hp may or may not have sealed bearings. For these larger motors, lubrication intervals vary between manufacturers but generally lubrication every 2000 hours is required. Consult Your Local Motor Distributor For Lubrication Advice, or the motor information supplied with your pump.

5.2Motor Removal: XB and XC Motor Adapter Pumps

STEPS

1.Disconnect the motor electrical power.

2.Remove the wiring to the motor.

3.Remove the piping from the pump.

4.Remove the pump mounting bolts, and place the pump on a work bench.

5.Remove the cone-point set screw from the shaft coupler, which is located through either side port in the motor adapter adjacent to the inlet housing. Do not remove the two knurled cup-point set screws securing the shaft coupler to the motor shaft at this time.

6.Remove the four (4) 5/16-18NC bolts that hold the pump liquid end to the motor adapter.

7.Slide the liquid end assembly away from the motor adapter 1/4- to 1/2-inch (6 - 13 mm).

8.Use two (2) flat-blade screwdrivers or small pry bars to remove the seal hold- er from the motor adapter along with the pump shaft (Figure 4.5, Removal of Pump Liquid-End from Motor Adapter). Remove the liquid-end assembly including the pump shaft as a unit.

9.Remove the four (4) 1/2-12NC bolts that hold the motor adapter to the motor and remove the motor adapter.

10.Loosen the two set screws that hold the shaft coupler to the motor shaft, and remove the shaft coupler. The motor may now be serviced by a qualified ven- dor or replaced (Figure 4.6, Removal of Mechanical Seal Holder from Motor Adapter).
