6.6.14 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.

6.6.15 Install the back pull-out assembly (except HT 3196)

WARNING:

Lifting and handling heavy equipment poses a crush hazard. Use caution during lifting and
handling and wear appropriate Personal Protective Equipment (PPE, such as steel-toed shoes,
gloves, etc.) at all times. Seek assistance if necessary.

Clean the casing fit and install the casing gasket (351) on the seal chamber and stuffing-box cover.

Loosen the clamping bolts (370C) and jack bolts (370D) on the bearing housing.
