7. grease the spherical housing with silicon waterproof grease;
8. place the track on the three spherical thrust bearings, making sure that the sphere is
properly positioned in its housing;
9. level and position the track by regulating the base washers and the spherical housing
plate;
10. regulate the height of the spherical housing plate so that the sphere is positioned in its
housing a little further than its maximum circumference (Fig. 4.15) but without touching
the bottom;
11. check the spherical housing is level, it is easier to perform this operation after removing
the linear scanner;
12. tighten the spherical housing plate tighten the nuts against the base washers, making sure
that the three washers do not rotate thus loosing the position obtained previously , and that
the fork is in the correct position, perpendicular to the axis of the track.
(WARNING: IN ORDER TO CONSERVE THE REFERENCE POSITION, THE
POSITION OF THE BASE WASHERS AND THE SPHERICAL HOUSING FIXED AT
THIS POINT MUST NOT BE MODIFIED FROM NOW ON)

position, centre shows the sphere position too high, right shows the sphere touching the

13. reposition the linear scanner on the three studs;
14. block the positioning fork M10 buffer screw with the lock nut and M10 washer, taking
care that the stud remains in the centre of the flange hole to permit the track to
elongate/contract due to thermal excursions. Use a marker pen (or a little resin or wax) to
mark the position of the nut with respect to the positioning fork so as to have a reference
for repositioning the linear scanner, since the nut cannot be moved after it has been fixed;
NOTE
: be especially careful when mounting the positioning sphere, which is fundamental when
repositioning the instrument. The spherical housing is countersunk to make the insertion of
the sphere easier, so the maximum circumference of the sphere should pass this
countersinking without touching the bottom of the spherical housing, to ensure the
reference is high precision. Regulate the height of the spherical housing plate until this is
achieved.
