3HAC052853-001 Revision: M

Secure the cross roller bearing to the frame

in two steps;

Tighten the 18 attachment screws

crosswise to 100 Nm.

Tighten the screws crosswise to 300

Use a torque converter between the screw

and the torque wrench, to facilitate the

tightening of the screws.

Use caution when attaching the screws that

secure the gearbox.

If a screw is dropped, it will probably end

up in the recess underneath the gearbox

and be very difficult to reach. Using a

magnet will probably be the only way to get

hold of the lost screw.

Fit the attachment screws that hold the

gearbox to the frame. Do not tighten yet.

This procedure is best done with two per-

sons working together:

Person one: working under the base,

holding the torque wrench in place,

making sure the bit is correctly fitted.

Person two: working beside the ro-

bot, working with the torque wrench.

Remove the guide pins and attach the re-

maining screws.
