Reassembly
1) Before beginning to reassemble the pump, make sure all the pump parts and your work
area are clean. The clearances of the pump are very tight, and even small particles can
damage the pump or keep it from functioning properly. Carefully refer to the parts diagram to
ensure the proper selection and orientation of all parts.
2) Start by assembling the graphite and rotor. Locate the rear flange. Use the parts diagram
to verify that you have the correct flange, as the front and rear flange look similar. Insert the
long shaft end of the rotor through the hole in the center of the flange.
3) Hold the assembly with the shaft pointing straight down. Locate the two pins (these are
used in all 70-400 series pumps, and in only Viton versions of the 500-1000 series pumps).
Verify that they are both the same length. Using tweezers, insert the two pins into the center
of the rotor, perpendicular to each other. The flat sides of the pins should be touching each
other (070-400 series).
4) Locate the 4 vanes. Insert one vane in each slot of the rotor, being careful not to knock the
pins out. Make sure that the radiused or chamfered edge faces outward.
5) Locate the liner and place it over the rotor, either side facing up, but making sure that the
alignment pin notch matches the rear flange.
6) Now locate the front flange. Place the front flange over the top of this assembly using the
parts diagram to verify the orientation.
8) Now take the rotor/graphite assembly and put it with the front flange down on the base of
your arbor press. Center the shaft with the ram.
