assembly and torquing of all hardware. This may be
purchased as part number C126758, 50ml bottle.
Note 2 – 4 of the hi-tensile bolts and/or nuts, that are
used to connect the driveshaft to the drive disc and
that connect the driveshaft to the pump companion
flange, will require a “crow’s foot” wrench attached
to a standard torque wrench in order to apply the
required tightening torque. A standard socket will
not work due to close proximity of the bolts and/or
nuts with the driveshaft yoke. The tightening torque
values listed for these bolts and/or nuts have been
corrected for using a “crow’s foot” adapter which
extends the standard torque wrench’s length.
Note 3 – For the high torque required for these nuts it
is recommended that a boxed end crows foot be used.
The following steps describe the proper way to check
alignment. A small pocket scale or ruler with
millimeter markings is recommended to make all
measurements.
A)
To check the Horizontal Parallel Offset, the
driveshaft must be in the proper orientation.
1.
Rotate the shaft so the reference “AB” on the
flywheel adapter disc or the circumference of
the drive shaft flange (against the flywheel
adapter disc) is in the 12 o’clock position
shown on
figure #7a.
2.
Measure from the face of the flywheel
adapter disc to point E. (Point E is on the
bearing bore as shown in
Figure #7a
). This
measurement must be:

123.5 ± 1.5mm
SC2160A
142.5 ± 1.5mm
SC2390 / SC2390A
Figure #7a
B)
With the driveshaft in
the same
orientation as
the previous step (Step A), check the
Horizontal Angular alignment of the shafts.
1.
Measure from the mating surface of the
companion hub to point G shown on
figure #7b. (Point G is the furthermost
point on the bearing bore). This
measurement must be equal to the
measurement at point E + 0.5 mm.
Figure #7b
C)
To check the Vertical Parallel Offset, the
driveshaft must be re-orientated.
1.
Rotate the shaft 90
○
so the reference
“CD” on the flywheel adapter disc or the
circumference of the drive shaft flange
(against the flywheel) is in the position
shown on
Figure#7c.
2. Measure from the face of the flywheel
adapter disc to point H. (Point H is the
furthermost point on the bearing bore
diameter). The measurement must be:
