g.
Hold the outlet support plate (13) and flex side plate (12) together and assemble over the cam ring (14) and rotor
(16) with the scribe marks in-line. Hold the cartridge together to prevent movement and turn the assembly over
so the outlet support plate rests on a flat surface and the wood strip is on top. Remove the wood strip.
h.
Lubricate the exposed surface of the rotor and vanes with hydraulic fluid. Locate the scribe mark on the inlet
support plate (9) and flex side plate (12). Hold the inlet support plate and flex side plate together and assemble
over the cam ring (14) and rotor (16) with scribe marks in-line.
i.
Thread two socket head screws (8) into the cartridge until snug (hand-tight).
NOTE
The outside diameter of all components of the cartridge kit must be in-line with each other or
the cover cannot be installed.
j.
Install the cover (3) over the cartridge. Tap lightly on the cover with your hand until each part centers. Remove
the cover gently so as not to disturb alignment. Torque socket head screws (8) to 45 inch pounds and recheck kit
alignment with the cover. Repeat until cartridge kit is aligned.
k.
Check rotor (16) for binding by inserting your index finger through the shaft opening of the inlet support plate (9).
Hold the cartridge kit in a horizontal shaft position and lift the rotor with your finger. The rotor should move freely
back and forth within the cartridge. If the rotor binds, open the kit. Clean and stone all possible areas of bind,
then reassemble using the above procedure. The rotor MUST move freely within the cartridge when assembled.
I.
Assemble the basic pump. Clamp the body (23) in a vise as before. Lubricate the primary shaft seal (22) with
petroleum jelly and place in position with the body, garter spring up. Use a seal installation tool to prevent
damaging seal. Press the seal into the body until it bottoms out.
m.
If the bearing (19) was removed from the shaft (20), install the shaft (20) in the bearing (19) while supporting the
bearing inner race. Afterward, install small snap ring (18).
n.
Place the bearing spacer washer (21) over the shaft (20) against the front of the bearing (19). Lubricate the shaft
with petroleum jelly and carefully push the shaft through the seals (22) until the bearing and spacer are in
location in the body (23). Install the large snap ring (17) in the body snap ring groove behind the bearing.
o.
Install the square sealing ring (7) into the body (23). Install the o-ring (5) and back-up ring (6) on the hub of the
outlet support plate (13). Carefully install the cartridge into the body so one of the chamfers on the cam ring is
alined with the cover (3) inlet port. Lubricate and install the large o-ring (4) in the cover.
