Apply a light coating of
grease to the new
section seals and place
them into the machined
grooves on both sides
of the gear housing.
Check the section seals
for proper fit.
Locate the orientation
mark on the gear
housing and line it up
with the mark on the
shaft end cover. Slide the
gear housing over gear
set. Make sure the gear
housing rests tightly
against shaft end cover.
Be careful not to pinch
the section seal. Squirt
clean, hydraulic oil over
the gear shaft and the
idler gear to provide initial
lubrication when the
pump is started.
Insert the pocket seals
into the thrust plate and
install onto the port end
cover following the
previous instructions in
steps 8 & 9. Then place
port end cover over the
gear journals. The
orientation mark on port
end cover must line up
with the mark on the gear
housing. Also, be sure
bearing bore holding the
ring seal goes over the
drive gear journal. Apply
pressure to the casting
with your hand or tap
lightly with a soft-faced
hammer until the port
end cover rests tightly
against the gear housing.
Thread the four, cap
screws with the
washers into the shaft
end cover and tighten
them in a cross-corner
pattern. Rotate the gear
shaft of the pump with a
6” wrench to make
certain there is no
binding in the pump.
After the cap screws
are tightened, make
certain there is no
internal binding of the
gear set by rotating
the gear shaft, then
tighten the cap screws
in a cross-corner
pattern to a final
torque of 2400 in. lbs.
(200 ft. lbs.).
