7. PUMP ASSEMBLY (continued)
CAUTION: BE SURE BEARING HOUSING/CASING MATING SURFACES ARE CLEAN AND FREE FROM BURRS, AS THIS WILL AFFECT THE ALIGNMENT OF THE ROTOR/CASING.
L.Attach the bearing cartridges to the lower casing using the appropriate dowel pins (158B).
M.Inspect the upper casing (3) to assure that the water passage is clean and free from foreign material. Apply a light coat of grease to the upper and lower casing mating surfaces and install a new casing gasket (157) on the lower casing, making sure the holes are aligned. Position the pins in the casing wearing rings to align with the slots in the lower casing. Lower the upper casing into position. Install the casing alignment pins and securely bolt the upper and lower casing together using the capscrews.
N.Install the packing (212), lantern rings (10), split glands (19) and gland nuts.
The pump assembly is now complete except for packing adjustment, which should be accomplished after the pump is installed, primed and started up. Refer to the maintenance section of this manual for specific packing adjustment instructions.
