DISMOUNT PROCEDURE
1.
Remove lock clip from the Mount nut and loosen the set
screw on dismount nut.
2.
Remove lubricatable auxiliary seal from OD of Mount and
Dismount Nuts. Be careful not to damage the two O-rings
in bore of seal. Remove weight from shaft.
3.
Scribe a line on the Adapter face and Mount Nut.
4.
Incorporating a spanner or drift and hammer, rotate the
Mount Nut counter clockwise two full rotations. The Mount
Nut must remain loose during the dismounting procedure,
but should never be removed. Without loosening the
mount nut, the mount nut piston will make contact with the
bearing unit as it travels down the adapter. (See Figure 3)
This will not allow the bearing to move down the adapter
and loosen from the shaft properly.
5.
Using a spanner or barring rod, rotate the Dismount Nut
clockwise until snug. This allows the dismount nut piston
to be in full contact with the bearing unit so that when the
dismount nut is pressurized with hydraulic fluid, the piston
will push the bearing unit down the adapter and properly
loosen from the shaft.

NOTE: Once the bearing is properly mounted, ensure the
anti-rotation plug is positioned so that it is aligned with the
machined groove in the cab housing.

Attach the hydraulic pump to either of two supplied G1/4
- 19 BSPP hydraulic ports found on Dismount Nut. The
hydraulic ports contain pipe plugs and are located on the
face and OD of the nut 180° apart.
Actuate the hydraulic pump until the pressure reading rises
for initial break away load then decreases to zero. This will
require repeated actuation of the pump. Once the pressure
reaches zero, the bearing has been fully dismounted.
Periodically check the mount nut to ensure that it is loose
during the dismounting process.
NOTE: If hydraulic pressure reaches 345 bar, abort
procedure by releasing pressure to the hydraulic
pump. Check to ensure the Mount Nut is still loose.
If not, rotate it counter clockwise 1 full rotation and
repeat Step 5.
Release pressure to the hydraulic pump and rotate
Dismount Nut in the clockwise position until snug. This
forces the hydraulic fluid back into the pump.
