Install o-ring (24) in the flange
plate. Use heavy grease to hold
the o-ring in the groove while the
plate slides down over the shafts.
Refer to Step 32 and use the same
precautions in the final assembly
of the flange plate. (Figure 65)
Install washers (26) and nuts (23).
Tighten two opposite nuts. Use a
10" wrench to check the shaft for
binding. It should turn with 5 to
7 pounds-feet of torque applied.
(Figure 66)
If the shaft will not turn properly,
disassemble the pump and examine it
for burrs or foreign material caus-
ing build-up or interference with
the parts. Also check for the
isolation plate with the radius
edge not being in the bottom of the
gear bore.
