Extractor Magnet Alignment

  1. Carefully raise the magnet assembly by hand. To do this, pull up on the magnet holder while turning the white gear manually. Raise the magnets until the top of the magnets are even with the top of the heaters on the Gort board (Heater Block) sub-assembly.

  2. Insert the magnet alignment tool between the Gort Board Heaters and the Magnets. Ensure that you are using the correct tool number according to the magnet assembly version (3-magnet or 12-magnet).

    If aligning the newer style assembly, DO NOT STRIKE any of the 12 magnets, as it may cause them to become loose from their fixtures).

  3. Slide the alignment tool to each end of the magnet sub assembly and try lifting it out.
    • If there is no frictional resistance, the magnets are too far from the heat blocks.
    • If the magnet alignment tool could not fit in, the magnets are too close from the heat blocks.

  4. To adjust the gap between the magnet and the heat blocks, loosen the 8 screws by ½ turn, with the 3/32 inch Allen wrench. There are 4 Allen screws on each side, as shown in picture below.

  5. By moving the magnet, adjust the gap between the magnets and the heat blocks until the tool fits snuggly and only a slight bit of resistance is felt when lifting the tool.
  6. When finish adjusting the gap, tighten the eight Allen head screws.
  7. Gently raise the magnets until they touch the bottom of the rear part of the alignment tool
  8. Check to see that the magnet assembly is level with the Gort heater blocks.
  9. Check the entire length of the Magnet Assembly by moving the alignment tool from one end of the assembly to the other. If the alignment tool touches the magnet assembly on both sides then they are leveled.
    • If there is a gap on one side, the magnets need to be rotated slightly.

  10. To rotate the magnet assembly, take out the Phillips screws to remove the back plate of the extractor module.

    If the back plate cannot be removed, move the magnet assembly down until you have access to the Allen screws.

    1. Loosen the four Allen screws on the back of the magnet sub assembly by ½ turn and adjust the angle. There is only around 1/16 inch of play. After the magnet level is adjusted, tighten the screws and reinstall the extractor back plate.

    1. Slide the alignment tool to each end of the magnet sub assembly and try lifting it out. If there is no frictional resistance, the magnets are too far from the heat blocks.
    2. Loosen by ½ turn the eight Allen screws shown (four on each side).

    3. Moving the alignment tool to the left and right sides of the magnets, adjust the gap between the magnets and the heat blocks until the tool fits snuggly, i.e., with only slight resistance when lifting the tool. Verify that the magnets are in line with the GORT board heaters and are not tilted, using a level.
    4. Tighten the eight Allen screws.
  11. After aligning both extractor magnets, re-assemble the instrument.
  12. Run the init.script from Script-O-Matic to ensure the magnets are working properly.
