DISMOUNT PROCEDURE

Remove lock clip from the Mount nut and loosen the set

screw on dismount nut.

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.

Scribe a line on the Adapter face and Mount Nut.

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.

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.

Non-Expansion Spacer

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.
