Action
If the robot is going to work in a water jet applica-
tion cell:
Apply Mercasol 3106 on the support shaft axis 2.
• Apply Mercasol 3106 on both sides of the
thrust washer, all around the bearing and on
surface on the shaft.
Push the shaft in by hand.
Refit the thrust washer to the shaft.
Apply the press device, axis 2 shaft against the
shaft.
Tighten the M16 nut.
Fit both the hydraulic pump and the glycerin pump
to the press device.
Set the indicator on the press device to zero.
Press in the shaft with the hydraulic cylinder by
setting the pressure of the hydraulic pump to ap-
proximately 35-55 MPa and the pressure of the
glycerin pump to 55 MPa.
Increase the pressure of the both pumps alternately
until the correct value is reached with the indicator
on the press tool.
When a correct value is reached, release the
pressure from the glycerin pump first, then from
the hydraulic pump (approximately 1/2 minute
after), in order to avoid movement of the shaft.
Remove the press device, axis 2 shaft.
Apply grease to the location of the shaft where the
bearing is to be mounted.
