11.Prepare lifting equipment to install the bearing housing. Screw in lifting eyebolts into
the top of the bearing housing. Lift the bearing housing and place it around the shaft.
Align housing flange with lower casing.
12.Screw the bearing housing into the lower casing. Thread in the jacking screws for
future use and to prevent thread corrosion.
13.Insert grease cup into the top of the bearing housing.
14.Insert drain plug into the bottom of the bearing housing.
Note: If using oil lubrication, see Oil lubrication for bearings assembly on page 91 for
the alternative assembly process.
15.Plug remaining openings of the bearing housing unless vibration and temperature
sensors will be installed at the end of the pump assembly.
16.Slide bearing gland, gasket and bearing seal ring against the bearing housing. Tighten
the bearing gland bolts.
Important: Do not tighten bearing seal ring set screws until the inboard bearing
housing assembly is fixed to the pump. Tightening the seal ring set screws requires the
shaft to be rotated. Rotating the shaft with unbalanced loading can cause property
damage.
17.Fasten the outboard bearing gland (end cap) with its gasket to the bearing housing.
18.Repeat steps 1-16 for the inboard bearing housing.
Note: Omit steps 6, 9 and 10.
19.Repeat steps 1-3 for the inboard bearing gland and seal ring. Install the bearing gland
assembly onto the inboard face of the inboard bearing housing.
