Bearing Oil Lubrication Recommendations
There are three plugs located in the bearing housing as shown in
Figure 12 below. To determine if the
bearings are properly lubricated, remove the level plug. If oil is not visible, remove the fill plug and fill
the bearing housing until oil is visible through the level plug hole. Replace both plugs.
For proper lubrication and maintenance, use the following guidelines:
1. Use Lubriplate FMO 2400 AW gear oil or equivalent food grade oil in the bearing housing.
2. Check the oil level weekly. Be sure that all plugs are fully tightened when installing to prevent
water or other foreign matter from entering the bearing housing.
3. Change the oil every 5000 hours of operation for ambient temperature pumpage. Change the oil
every 2000 hours of operation for pumpage above 150°F.
4. Fill the bearing housing with oil only to the level hole, as overfilling may cause the bearings to fail
prematurely.
