14. PICK-UP REPLACEMENT AND ADJUSTMENT
To replace the pick-ups, follow this procedure:
- Disconnect the connection of the pair of pickups from the
MBUGRF
board (D fig. 3);
- loosen the pick-up pre-load springs completely (A, Fig. 10);
Fig. 10
- Unscrew the two M10 dowels and replace the pick-ups (B, Fig. 10) with the new ones;
- assemble the new pair of pick-ups, ensuring that the spheres are correctly positioned inside the appropriate niches, and that the pick-up
marked with the letter I (internal) is assembled on the right and the one with the letter E (external) is on the left (assuming you will work from
in front of the machine);
- tighten the fixing dowels so that the pick-ups are slightly rubbed;
- tighten the locknuts as far as the blocking point, then unscrew them slightly (by about one side of the hexagon) so that the Belleville washers
are working.
