The procedure below details how to refit the lower arm shaft.
10. Increase the pressure of the both pumps alternately
11. When a correct value is reached, release the
12. Remove the press device, axis 2 shaft.

Action
1. Clean the shaft with isopropanol and lubricate it
with glycerin.
2. If the robot is going to work in a water jet application
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.
3. Push the shaft in by hand.
4. Refit the thrust washer to the shaft.
5. Apply the press device, axis 2 shaft against the
shaft.
6. Tighten the M16 nut.
7. Fit both the hydraulic pump and the glycerin pump
to the press device.
8. Set the indicator on the press device to zero.
9. Press in the shaft with the hydraulic cylinder by
setting the pressure of the hydraulic pump to
approximately 35-55 MPa and the pressure of the
glycerin pump to 55 MPa.
until the correct value is reached with the indicator
on the press tool.
pressure from the glycerin pump first, then from the
hydraulic pump (approximately 1/2 minute after), in
order to avoid movement of the shaft.
