The 1/2 in. NPT connection (551E) remains plugged because it is not required in the oil-mist sys-
tem.
2.
On the thrust housing, replace the 1/4 in. NPT plug (133H) with an oil-mist fitting. Replace the 1/2
in. NPT plug (551E) with a 1/2 in. to 1/4 in. bushing and insert an oil-mist fitting provided by the oil-
mist system manufacturer.
3.
For pure-oil mist, connect the drain lines (408A) to the outlet connections. This is not required for
purge-oil mist.
5.5.7 Lubricate the bearings with pressurized lubrication
Pressurized lubrication requires a separate lubrication oil skid to provide cool, clean oil to the bearing
housings. The lubrication oil skid shall be in operation to ensure oil flow into the bearings prior to pump
operation. The pump may have been supplied with orifices or valves to control inlet flow to each bearing.
Refer to the General Arrangement drawing for additional detail.
1.
Prepare the lubrication oil skid according to the manufacturer's instructions.
2.
Connect the lubrication oil skid supply lines to the bearing housing connections as shown in
31: Oil feed location on page 51
3.
Connect the bearing housing drain piping back to the lubrication oil skid as shown in
.
