Oil lubrication
LF pumps with oil lubricated bearings are fitted with a transparent
reservoir, a constant-level oiler, that maintains the oil level about
the centerline of the bearing. See fig. 7.
• Follow a regular oil maintenance program. When necessary,
renew the oil supply in the reservoir of the constant-level oiler.
• Change the oil after the first 200 hours of operation. To change
the oil, remove the drain plug at the bottom of the bearing
cover and the filler plug, that also acts as a vent plug, at the
top of the bearing frame. After draining the oil, replace the
drain plug and refill the reservoir with an oil from the table List
of acceptable oil lubricants on page 12. After the first oil
change, the oil must be changed again at 2000 hours and then
at intervals of 8000 hours or once a year, thereafter.
