• New bearings
• Exxon Polyrex EM grease
Exxon Polyrex EM grease is the only recommended grease. Do not use any other
grease.
• Grease gun
• Hardware removal tools

1. Grease cup
2. Breather vent
3. Drain plug
4. Miscellaneous plugs
Thoroughly clean out the bearing housing before regreasing the bearings. Ensure all
dust, debris, or other contaminants are removed.
1. Seal the bearing housing, ensure all miscellaneous plugs are fastened into place
excluding the grease drain located underneath the bearing housing. This will ensure
proper filling of the bearing cavity and also keep foreign debris from entering the
bearing housing.
2. Insert the breather vent into the top of the bearing housing.
3. Insert the grease cup into the top of the bearing housing.
4. Using a grease gun, inject Exxon Polyrex EM grease into the grease cup. Stop adding
grease when it exits the drain plug located underneath the bearing housing.
5. Run the pump for 30-60 minutes to remove excess grease from the bearing cavity.
6. Insert the drain plug beneath the bearing housing.
WARNING:
Do not over-grease the bearings. Too much grease may overheat the
bearings and cause property damage.
Oil lubrication
Oil lubrication is maintained with Trico
®
constant level oilers which are monitored with
sight glasses mounted to the side of the bearing housing. The standard Trico
®
oiler
requires venting at the top of the bearing housing. See section 6.2 for more information
on monitoring the oil level with a sight glass. The following figure demonstrates the
standard oil lubrication setup.
