5.2.7 Lubrication
The bearing housing shall be filled with proper
lubricating oil prior to start up. If the pump will be
started after a longer storage period, the bearing
housing should be first flushed and cleaned with
gasoline. It is not necessary to remove the
preservation oil as this will mix up thoroughly with the
lubrication oil.
Lubrication is provided by the pumping effect of the
rotating ball bearings. Maintaining the correct oil level
(middle of the oil sight glass) ensures that the lower
ball bearing is covered with oil.
For recommended lubricating oils refer to the
lubrication table 5.2.6
5.2.8 Oil change
After first start up, the oil shall be changed after 200
service hours.
Every further oil change shall take place after about
2000 service hours or at least every 6 month.
To change the oil, use the following procedure:
a) Remove the reservoir (for some type of oilers you
must loose a fixing screw or lock nut, refer to
section 5.2.3 Oil level).
b) Open the oil drain on the bearing housing to remove
the oil.
c) Close the oil drain and fill in Oil through the oiler until
the oil level reaches the bottom of the sight glass.
d) Fill the reservoir and put it quickly to the body of the
oiler. Observe the level in the reservoir. It will
decrease until the required oil level is reached
(middle of the sight glass). Ensure that enough oil
remains in the reservoir.
e) If necessary, the oil level can be adjusted by refering
to section 5.2.3 Oil level.
5.2.9 Oil level
The correct oil level is in the middle of the oil sight glass
and shall be checked when pump is not in operation.
Periodically check if the lubricating oil is mixed with any
condensed water. Careful opening of the oil drain
during a stop of the pump will show any water.
Use a spirit level to check the horizontal
alignment of the bearing housing.
A too high oil level will result in higher bearing
temperatures and therefore poorer lubrication.
5.2.9.1 Adjusting of ADAMS Constant Level Oiler
This design of Constant Oiler prevents the flooding of
the bearing by means of the positive setting in the
Oiler, thus maintaining the correct oil level at all
times. When these Oilers are used on Ball or Roller
bearings, the installation is the same as described
below, excepting that the oil level in the bearing
should never cover more than maximum above inside
diameter of the outer race at its lowest point.
If the pump is fitted with a Constant Level
Oiler type "ADAMS", no adjustment of the oil level is
possible.
