OPERATION
When the engine is running, the oil is pumped through
the inlet chamber (5) along the upper and lower side
of the crescent to the pressure chamber (6) of the
housing. The meshing of the teeth prevents oil flowing
from the delivery side to the intake side. An external
gear (3), eccentrically mounted in the pump housing,
is located on the internal gear (4) which is connected
to the drive flange. The crescent (1) drives the exter-
nal wheel.
DISASSEMBLY
1. Remove the pump gears (1 and 2) from the pump
housing.
