Action
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.
Press in the new bearing with the press tool, axis
2 bearing.
Refit the protection washer and the retaining ring.
Refit the protection plug.
Proceed with the refitting procedure of the lower
arm, detailed in section Replacement of complete
lower arm on page 264.
Action
Clean the shaft with isopropanol and lubricate it
