1. Clean the casing fit and install the casing gasket (400) on the seal chamber and stuffing-
box cover.
2. Install the back pull-out assembly in the casing.
Figure 29: Install back pull-out assembly
3. Install and then hand-tighten the casing bolts (370).
Refer to the bolt torque values for information on how to tighten the casing bolts.
4. Install and tighten the casing jackscrews.
NOTICE:
Do not overtighten the casing jackscrews. Doing so may result in equipment damage.
5. Turn the shaft by hand in order to make sure that it moves freely.
The shaft seal can cause a slight resistance, but there must not be any metal-to-metal
contact.
6. Reinstall the shims under the frame foot and tighten the frame foot to the baseplate.
Make sure that you use the proper shim. Mount a dial indicator in order to measure the
distance between the top of the frame and the baseplate. Make sure that the distance does
not change as you tighten the frame-foot bolts.
7. Replace the auxiliary piping.
8. Fill the pump with the proper lubricant. See Lubricating-oil requirements.
9. Reinstall the coupling guard.
See Install the coupling guard for more information.
NOTICE:
When a cartridge mechanical seal is used, ensure that the set screws in the seal locking ring
are tightened and that the centering clips have been removed prior to startup. This prevents
seal or shaft sleeve damage by ensuring that the seal is properly installed and centered on the
sleeve.
Post-assembly checks
Perform these checks after you assemble the pump, then continue with pump startup:
• Rotate the shaft by hand in order to make sure that it rotates easily and smoothly and that
there is no rubbing.
• Open the isolation valves and check the pump for leaks.
