£ Grease the shaft sealing ring part 7
with some oil and push it into the
housing of the Z axis (part 3) from
the outside.
£ Some remains may have gathered
in the holes due to the surface treat-
ment of the housing which may
cause that the shaft sealing ring is
difficult to mount. If required regrind
the hole with a fine abrasive cloth.
Illustr.: 4-48: Assemble shaft sealing ring
£ Insert the pulley (part 1) into the
housing. Here some oil should be
applied on the shaft release of the
pulley in order that the sealing lips of
the shaft sealing ring will not be
damaged.
Illustr.: 4-49: Insert pulley
£ Screw the pulley with the fork
wrench onto the spindle in order to
be able to mark out the hole to fix
the housing.
£ Mark out the holes with a pen on the
lathe back.
