3.1.3.2.  Place both spacers of the matched pair of bearing spacers (23) on the 

thrust bearing.  Heat a new radial bearing (13A) to 150-175 degrees F 
and place it on the shaft against the inner bearing spacer with the wide 
face of the inner race facing away from the matched pair of bearing 
spacers (23). 

 
 

4.  HYDROSTATIC PRESSURE TEST 

4.1.  Hydrostatic pressure tests can not be performed on assembled pumps because of possible seal 

damage.  Hydrostatic pressure test, if desired, can be performed on the manifold, rotor and/or rotor 
cover. 

 

4.2.  Manifold - Hydrostatic test suction to 1-1/2 times the maximum inlet pressure.  Test outlet to 1-1/2 

times the maximum discharge pressure shown on pump performance curves.  Hold test for 10 
minutes. 

 

4.3.  Rotor and rotor cover.  Hydrostatic pressure test to 1-1/2 times the maximum inlet pressure.  Hold 

test for 10 minutes. 

 
 

5.  ROTOR ASSEMBLY BALANCING 

5.1.  If rotor has been removed or any rotating components, i.e., shaft, rotor or rotor cover replaced, the 

rotor assembly must be dynamically balanced in accordance with section 5.5. 

 

5.2.  Rotor cover installation.  Lubricate and install o-ring (6)  on the lip of the rotor (3).  Lubricate the o-

ring bore in the rotor cover which engages the o-ring.  Place the rotor cover on the rotor.  Be sure all 
holes in the periphery of the rotor cover line up with the tapped holes in the rotor, as the hole pattern 
is not symmetrical.  Make sure rotor capscrews are installed in same location from which they were 
removed.  Tighten evenly the sixteen rotor cover capscrews (7) to draw the rotor cover down.  It is 
important that the rotor cover does not cock, as the o-ring might be damaged.  Torque the 
capscrews to 100 ft. lbs. 

 

5.3.  Completely fill rotor cavity with liquid of required specific gravity.  Seal off.   

 

5.4.  Position half key in shaft. 

 

5.5. 

Two plane dynamic balance using surface A and B shown on figure 2.5.  Trim balance to 1/2 of the 
out of balance by drilling as indicated on figure 2.5.  Balance to within the following limits at 975 to 
1000 RPM: 

Caution:

 

Sufficient guarding should be used when balancing the rotating assembly. 

 

.15 in .oz max. 

 

5.6.  Drain rotor assembly. 

 

5.7.  Remove rotor cover (3) to prepare for next assembly step.  See section 2.9.4.
