ROTATING COMPONENT REPLACEMENT
5.1. ROTOR
REMOVAL
5.1.1
Remove the six socket head cap screws (83) which secure the rotor (3) to
the driveshaft.
5.1.2
Mark the driveshaft (5) and the rotor (3) so that they may be reassembled
with the same relative positions for balance considerations. Thread two
cap screws evenly into the two tapped jackscrew holes in the driveshaft
flange until the driveshaft is released from the rotor.
5.2. ROTOR
INSTALLATION
Be sure the rotor plug (133) and the o-ring (134) are in place in the rotor
(3). Heat the driveshaft bore in the rotor (3) to 140°-160° F max. Check
the temperature with a heat stick. Insert the driveshaft aligning the before
disassembly alignment marks and driveshaft flange holes with the holes in
the rotor. Install the six socket head cap screws (83). Do not tighten the
screws until the driveshaft and the rotor have reached the same
temperature, then torque to 100 ft. lbs.
6.
HYDROSTATIC PRESSURE TEST
Hydrostatic pressure test cannot be performed on a fully assembled pump because of possible
seal damage. Parts are hydrostatic pressure tested at the factory.
7.
BALANCING (Rotor Assembly)
Note: ALL ROTATING COMPONENTS MUST BE THOROUGHLY CLEAN BEFORE
ROTOR ASSEMBLY BALANCING IS DONE.
THIS SECTION PRESUMES THAT THE SHAFT (5) HAS ALREADY BEEN
ASSEMBLED TO THE ROTOR (3) PER
SECTION 5.2.
7.1
Rotor cover installation:
Lubricate and install the o-ring (6) on the lip of the rotor (3).
Lubricate the o-ring bore in the rotor cover (4) 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 cap screws are installed in same location from which they were removed.
Tighten twenty rotor cover cap screws (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 cap
screws to 68 ft. lbs.
7.2 Completely fill rotor cavity with liquid of required specific gravity. Seal off.
7.3 Position half key in shaft and securely tape to shaft.
