Oil volume requirements for sleeve/Kingsbury type bearings
The sleeve/Kingsbury type bearing is a pressurized lubrication system where oil is flowed into
the bearing. This system does not have an oil sump. The system requires a flow rate of 0.5
gpm (0.12 m
3 /hr) for the sleeve bearing and 1.0 gpm (0.23 m 3 /hr) for the Kingsbury bearing at
15 psi (100 kPA).
Lubricating-oil requirements
Oil quality requirements
Use a high-quality turbine oil with rust and oxidation inhibitors with rated viscosity shown below
at 100°F (38°C).
Oil requirements based on temperature
For the majority of operating conditions, bearing temperatures run between 120°F (49°C) and 180°F
(82°C), and you can use an oil of ISO viscosity grade 68 at 100°F (38°C). If temperatures exceed 180°F
(82°C), refer to the table for temperature requirements.

Lubricate the bearings with oil
NOTICE:
Do not expose an idle pump to freezing conditions. Drain all liquid that is inside the pump and
the cooling coils. Failure to do so can cause liquid to freeze and damage the pump.
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.
