NOTE: the generator ring and star have been marked
with a dot on each, the ring and star can be placed with
these marks up or down but both marks should be on
the same side.
2. For easier assembly, rotate the generator outer
ring to fully engage with the inner star. The fully
engaged side of the generator should point
towards the designed input rotation (CW or CCW
as noted on the housing).
NOTE: The designed input rotation is stamped on the
back side of the housing and also next to the generator
on the inside.
3. Freely lubricate the generator with clean hydraulic
fluid to provide lubrication at start-up.
4. The charge pump plate has a small arrow cast into
the outer face of the plate.
5. At assembly, this arrow must face toward the input
rotation designated in the housing.
NOTE: All applications are clockwise rotation (CW).
NOTE: High pressure charge pump - generator and
plate is a matched set and is not sold separately. Class
II generator and plate are not a matched set.
6. Aligning the rotation arrow with the input rotation,
install the pump plate over the generator.
7. Install the four cap screws in the pump plate finger

the pump journal, engaging the drive pins with the
inner star of the generator.
10.Rotate the pump rotor assembly several times to
center the pump plate on the generator.
