Action
Check the protection tube for damages.
Especially check the surface for the radial
sealing. See figure!
Replace if damaged.
Note
A sleeve is mounted on the protection tube
to ensure that the radial sealing seals prop-
erly against the tube.
Fit guide pins in opposite holes in the base.
Tip
Lubricate the guide pins with some grease
to make the gearbox slide better.
Wipe clean the contact surfaces on the base
and the surfaces of the protection tube from
