5.4.2.4 Lubricate the bearings with oil
WARNING:
Risk of explosive hazard and premature failure from sparks and heat generation.
Ensure bearings are properly lubricated prior to startup.
NOTICE:
Do not expose an idle pump to freezing conditions. Drain all liquid that will freeze that is inside
the pump and any auxiliary equipment. Failure to do so can cause liquid to freeze and damage
the pump. Note that different liquids freeze at different temperatures. Some pump designs do
not drain completely and may require flushing with a liquid that doesn't freeze.
Ring oil-lubricated pumps are supplied with an oiler that maintains a constant oil level in the bearing
housing.
1.
Fill the oil reservoir in the bearing frame:
a) Fill the bearing chamber through the main body of the Watchdog until it reaches the optimum
fluid level visible in the bullseye sight.
b) Fill the watchdog reservoir using a funnel.
c)
Verify o-ring is on the Watchdog oiler spout.
d) Place your thumb over the reservoir spout. Invert and insert the spout into the internal threaded
boss on the main body.
e) Tighten reservoir. Do not over-tighten.
f)
Verify that proper oil level is maintained per the following diagram.
NOTICE:
Do not fill the oil reservoir of the bearing frame through the plug at the top.
2.
Check that the oil level is correct. The correct oil level is centered in the bullseye sight glass, when
the pump is not in operation. During operation, bullseye sight gives a false oil level reading. Shown
is general schematic. Oil level is below outer race of bearing.
