The end cap can now be lifted off the pump; however,
be certain that the valve plate does not fall and become
damaged. If the valve plate tends to lift off with the end
cap, hold it in place on the end cap and remove both
parts together. If the valve plate remains on the bearing
plate, remove it at this time.
CAUTION
All surfaces exposed are critical and caution must
be used to avoid damage.
Note that the end cap is sealed to the housing with both
a gasket and an O-ring.
The end cap is actually an assembly consisting of a
tapered bearing race which is a slip fit in the end cap
and the valve plate locating pin. These parts should be
removed from the end cap. There may or may not be a
shim located under the bearing race which should be
removed.
The pump valve plate has two (2) tapered slots, one (1)
at the top and one (1). at the bottom of the plate.
These slots are on opposite ports for different shaft
rotations.
The valve plate on the left in the picture is for Left Hand
(CCW) rotation. The valve plate on the right is for Right
Hand (CW) rotation
.
