Repair Information
– Series 2 Variable Displacement Pump
Lubricate and install the
input shaft into the rotat-
ing group and swashplate
assembly. (see Figure 78)
Lubricate and install the
rear bearing on the shaft
and bearing assembly.
Support the shaft assem-
bly in a slightly raised po-
sition. Next use a hydrau-
lic press to press the rear
bearing cone on the shaft.
The bearing cone must be
firmly seated against the machined shoulder of the pump shaft.
NOTE: The bearing cone may also be heated for installation.
(see Figure 79)
In preparation of install-
ing the swashplate and
rotating group into the
pump housing it helps to
retain the two hold down
arms. To do this, install
two heavy rubber bands
across both arms. (see
Figure 80)
Lubricate and install the
slide block on the
swashplate. Before in-
stalling, apply a small
amount of petroleum jelly
to the back side of the
slide. This will help to re-
tain the slide block in po-
sition during assembly
into the pump housing.
(see Figure 81)
To help in the assembly of
the swashplate and rotat-
ing group into the pump
housing, reinstall the
bearing puller on the rear
bearing. The bearing
puller can now be used as
a handle to assemble the swashplate, rotating group and shaft
assembly into the pump housing. (see Figure 82)
VERY CAREFULLY pick up the
entire assembly and install it
into the pump housing. Install
by aligning the two notches lo-
cated in the swashplate with the
two clocking links and the
swashplate side with the notch
in the servo piston. IMPOR-
TANT: The swashplate assem-
bly must be firmly seated on the swashplate bearings. (see Figure
83)
Install the lower clocking link re-
taining plug. Torque plugs to
125 ft. lbs. [169,5 Nm]. (see
Figure 84)
Remove the bearing puller and
two rubber bands from the
swashplate assembly. (see Fig-
ure 85)
In preparation of zeroing in the
swashplate, first place a paral-
lel bars across the face of the
pump housing. Make sure
these bars are resting firmly on
the housing face. Next using a
depth micrometer, measure the
distance from the parallel bar to
the face of the swashplate.
Make note of this dimension.
(see Figure 86)
With the first dimension noted,
move the depth micrometer to
the opposite side of the swash-
plate and measure the distance
from the parallel bars to the face
of the swashplate. Again make
note of this dimension. With the
two dimensions noted, turn the
face of the depth micrometer so
that the zero position is right in between the two noted dimensions.
