Action
Inspect the o-ring.
Note
Replace if damaged.
Put some grease on the o-ring and fit it in
the oil hose groove.
Attach two guide pins in opposite holes of
the gearbox.
One of the guide pins shall be fitted in the
hole closest to the guiding pin.
Before fitting the gearbox, make sure that
the guiding pin and the oil canal will match
the holes in the frame.
Use caution and lift the gearbox onto the
guide pins.
Attach the 16 of the 18 attachment screws
that will secure the gearbox to the base.
Tip
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.
