4. Loosen the four (4) cap screws that secure pump as-
sembly.
5. Remove pump from vise and remove fasteners.
6. Support the pump assembly and gently tap the pump
case with a soft face hammer to loosen the pump sec-
tions. Be careful to not drop parts or disengage gear
mesh.
IMPORTANT: Mark the relative positions of the gear
teeth and the wear plates so they can be reassem-
bled in the same position. Do not touch the gear sur-
faces as residue on hands may be corrosive to gear
finish.
7. Remove the wear plates and seals from each pump
section. Before removing each gear set, apply marking
dye to mating teeth to retain ”timing”. Pump efficiency
may be affected if the teeth are not installed in the same
position during assembly. Discard removed seals.
8. Turn front flange over, with seal side up.
IMPORTANT: Make sure to not damage the front
flange counter bore when removing the seal from
the front flange.
9. Carefully remove retaining ring and shaft seal from
the front flange. Discard seal.
10.Clean all parts. Check all components for burrs,
scoring, nicks and other damage.
11.Replace the entire pump assembly if parts are ex-
cessively worn or scored.
Assembly (Fig. 39.1)
1. Lubricate O--ring, pressure seals, back--up gaskets
and wear plate grooves with a thin coat of petroleum jelly
to hold them in position during gear pump assembly. Lu-
bricate all other internal parts freely with clean hydraulic
oil.
NOTE: Pressure seals and back--up gaskets fit in
grooves machined into wear plates. The O--ring seal fits
in groove machined in body face.
2. Assemble pump starting at front cover end.
3. After pump has been assembled, tighten cap screws
by hand. Rotate the drive shaft to check for binding. Pro-
tect the shaft if using a pliers.
4. Tighten the four (4) cap screws evenly in a crossing
pattern to a torque of 33 ft--lb (45 N--m).
