Bearing preservation - generators with sleeve bearings
and self-contained ring oil lubrication.
1. Remove oil drain port plug and drain oil from the bearing (refer
to the specific generator outline drawing for drain location).
2. Identify the sleeve bearing casing oil inlet port on one side of the
bearing (refer to the specific generator outline drawing for oil
inlet location).
3. Attach a manual pump filled with Daubert Nox-Rust® VCI-10
oil. Flush 2 gallons of the preservative through the oil inlet port
for 1 minute at 2 GPM flow.
4. Drain the bearing casing after flushing and reinstall the oil drain
port plugs. Repeat this procedure for each bearing.
5. Repeat the flushing procedure every 12 months.
Bearing preservation - generators with sleeve bearings
and external lubrication system.
1. Disconnect external lubrication system following the
manufactures recommendations.
2. Identify the sleeve bearing casing oil inlet port on one side of
the bearing and the drain port beneath the bearing casing (refer
to the specific generator outline drawing for oil inlet and drain
locations).
3. Attach a manual pump filled with Nox-Rust® VCI-10 oil. Flush
2 gallons of the preservative through the oil inlet port for 1
minute at 2 GPM flow. Drain the bearing casing after flushing
and reinstall the drain and oil plugs. Repeat this procedure for
each bearing.
4. Repeat flushing procedure every 12 months.
Remove generator from storage
When the generator is taken out of storage, check the insulation
resistance on all windings. See page 31.
Clean the shaft of anti-corrosion agent.
NOTE:
It should not be necessary to open
the bearing for cleaning the remaining
preservative before starting the generator,
however, it is recommended to verify the
compatibility of the Nox-Rust® VCI-10
oil with the specific oil used to lubricate
the bearings.
CAUTION:
Before using this
product, the operator must carefully read
the MSDS sheet to ensure that the process
is carried out safely for the operator and
the environment.
