SECTION SIX - LUBRICATION
6.1 OIL RING LUBRICATION
6.1.1 Recommended Lubricant
The recommended bearing bracket oil is ISO VG 68 non-detergent oil. Turbine quality oil is preferred. This oil
may be used during break-in and normal operation.
6.1.2. Method of Application
Customer must fill bearing bracket before startup. The bearing bracket is supplied with a sight glass and a
constant level oiler. Fill the bearing bracket with oil according to the quantities specified in next section.
Start pouring oil into the bearing housing through the breather connection located at the top of the bearing
housing, leaving an amount equal to the capacity of constant level oiler bottle apart. Place the breather back on
its position. To finish this process, remove the constant level oiler bottle, fill it and place it back on its position.
The correct level is observed between the low and high marks on oil sight glass.
Adjust the oil in accordance with directions enclosed within the oiler glass to maintain the oil at the sight glass
level mark.
·
Oil level should be determined by using sight glass in bearing bracket. Oil
level in constant level oiler does not correspond to oil level in bearing
bracket.
·
Ruhrpumpen takes every precaution during our assembly process and
subsequent final assembly audits to ensure no Bearing Housing oil leaks exist
prior to shipment. Oil can leak past the labyrinth seal in an “overfill”
condition. Refer to the filling instructions for additional information
