2. Use a marker to make diagonal lines across the gear pump sections for
assembly purposes; refer to
IMPORTANT
Use caution when clamping gear pump in a vise to avoid distorting
any pump components.
3. Secure the front cover of the pump in a vise with the drive shaft pointing down.
4. Loosen the four (4) cap screws that secure the pump sections (P3) and (P4)
to the front cover.
5. Remove the pump from the vise and remove the fasteners.
Note:
Be careful to not drop parts or disengage gear mesh when separating
pump sections.
6. Support the pump assembly and gently tap the pump bodies with a soft face
hammer to loosen the pump sections.
IMPORTANT
Mark the relative positions of the gear teeth and the thrust plates so
they can be reassembled in the same position. Do not touch the gear
surfaces as residue on hands may be corrosive to gear finish.
7. Remove the thrust plates and the seals from each pump section. Before
removing each gear set, apply marking dye to the mating teeth to retain the
”timing”. Pump efficiency may be affected if the teeth are not installed in
the same position during assembly. Keep the parts for each pump section
together; do not mix parts between sections.
Inspecting the Gear Pump
If internal parts are found to be worn or damaged, gear pump replacement
is necessary.
1. Remove any nicks and burrs from all parts with emery cloth.
