2.3 Pressure Lubrication System
The pressure lubrication system, incorporating the oil pump for the F-series pumps, is shown in Figure
15: In this system, filtered oil is supplied to the pump through the suction filter (1) and is discharged
from the pump into the manifold block (2) and nozzle (3A). Oil is distributed into the main bearing oil
line (4) and the crosshead compartment oil distributor (4A) located above the crosshead compartment.
The crosshead compartment oil distributor (4A) distributes oil to the crosshead, crosshead bearings
and extension rods.
A pressure gauge (5) is mounted on the back wall of the frame to show oil pressure being maintained
in the oil distributor. The oil pressure will, of course, vary with the speed of the main pump, however if
a sudden pressure drop or increase occurs, refer to the section on maintenance of lubrication system
for possible cause.
