bor press with the spline ends of the shafts
facing down as shown in Figure 34. Press
on both shafts to remove them from the
gearbox until you hear a click. This will
be the sound of the snap ring falling into
the groove of the shaft behind the bearing
lock nut thread.
k) Pull the inner race of both rear bearings
out of the gearbox.
l) Remove the snap rings from the pump
shafts with the straight snap ring pliers.
Make sure to support the shafts so that
they do not fall and get damaged. The
front oil seals will come out of the gearbox
with the shafts.
m) Press the inner bearing races off both
pump shafts as shown in Figure 35. Note:
do not press on outer bearing cage. Set
pump shafts aside.
n) Remove the gears from the gearbox. The
outer races of both front and rear bearings
can now be tapped out of the gearbox with
a hammer and brass rod.

Note: For ease of installation , install the idle shaft first. If you are not sure about shaft location, the
drive shaft will always be located in the same bore on the gearbox. To locate the correct bore, stand
facing the gearbox with the gearbox cover on your left side. The drive shaft will be in the top bore posi-
tion.

Cover the coupling area of the drive shaft with tape, to protect it. Lightly oil the pumps shafts on the
step for the front bearings.
Assemble the bearings one
shaft at a time.
a) Heat the inner race of
the front bearings to
no more than 300°F
and quickly slide on the
shaft.
b) Let the inner races cool
and then use a piece of
0.0 mm shim stock to check if the bearing is properly seated against the step on both shafts.
c) If the inner race has moved, use a piece of mild steel pipe that only touches the inner race of the
bearing to seat the bearing cone against the shaft step. Slide the pipe over the shaft so it is seated
on the inner race of the bearing cone and use the Arbor press or a hammer to gently move the inner
race into place.
