9.
Attach a hydraulic pump to either of the two G1/4 - 19
BSPP Fitting hydraulic ports found on the Mount Nut. They
contain pipe plugs and are located on the face and OD of
the nut 180° apart.
10. Actuate hydraulic pump until Starting Position Pressure
(Table 1) is attained.
11. Install a magnetic base indicator or displacement gauge.
•
Displacement Gauge: Install gauge in hydraulic port on
face of Mount Nut. Follow instructions included with
gauge for proper installation.
•
Magnetic Base Indicator: Place on the shaft with the
anvil on face of inner unit as shown in Figure 2.
12. Zero the Indicator.
13. Actuate hydraulic pump until indicator indicates movement
as shown in the final position column of Table 1.
Periodically check the dismount nut to ensure that it is still
loose during the mounting process.
NOTE: If hydraulic pressure reaches 345 bar prior to
attaining Final Position, abort procedure by releasing
pressure to hydraulic nut. Check to ensure Dismount
Nut is still loose. If not, rotate it counter clockwise 1
full rotation and repeat Step 13.

14. Remove Indicator from shaft or displacement gauge from
mount nut.
15. Release pressure to hydraulic pump and rotate Mount
Nut clockwise until snug. This forces the hydraulic
fluid back into the pump. Failure to complete this step
may result in the locknut loosening during operation
after it is tightened.
16. Remove hydraulic attachment from Mount Nut and insert
supplied pipe plug.
17. Using a spanner or drift and hammer, drive the Mount Nut
clockwise until the lock clip can be inserted into one of the
adapter slots and aligned with the drilled and tapped lock
clip holes.
N OTE: Always tighten, never loosen, the Mount Nut.
18. Insert lock clip and tighten lock clip bolts.
19. Using a barring rod, rotate Dismount Nut clockwise until
snug.
20. Align one of the set screws with the slot in the adapter.
Rotate the dismount nut COUNTER CLOCKWISE if
necessary until a set screw engages the slot.
21. Tighten that set screw to 135 Nm (99 ft-lbs.)
22. Place the stabilizing ring over Mount Nut.
23. Install the lubricatable auxiliary seals onto the Mount and
Dismount Nuts. Ensure all burrs or sharp edges are filed off
the shaft, so that the o-rings in the seals are not damaged.
Install the Expansion (Float) Bearing
1.
Follow the same steps as outlined for the Non-Expansion
bearing.
2.
Skip Step 22 since t he stabilizing ring is not needed.
