5. See Figure 6-19. Inspect the gasket around the antenna of the new
magnetron, making sure it is smooth and free of debris.
6. Carefully insert the antenna through the hole in the wave guide.
7. Make sure the magnetron gasket is sealed evenly on the flange, then
secure the magnetron to the wave guide with the four nuts, washers,
and screws. Tighten the nuts to 1.9 NSm (17-in. lb).
8. Install one new black insulating sleeve (shipped with the magnetrons)
over the X1and HV cables. Install the other new sleeve over the X2
cable.
9. Use the screws removed in step 3 to connect the X2 secondary cable to
the magnetron F terminal pigtail. Connect the X1 secondary cable and
the 20 AWG HV cable with ferrite to the FA terminal pigtail.
10. Pull the black insulation sleeves over the terminals so that they are
completely covered. Secure the top and bottom of the sleeves with
cable ties.
Filament Transformer Replacement
NOTE: To replace both filament transformers, order two filament
transformer kits. The filament transformer kit contains one transformer, one
ferrite, two insulation sleeves, and four cable ties for the sleeves.
1. Follow steps 1−5 under Preparation on page 6-13.
2. See Figure 6-18. Cut the four ties securing the black HV insulation
sleeves to the HV cables at the magnetron. Slide the sleeves down to
expose the ring-tongue terminal connections.
3. Remove the two terminal screws and disconnect the cables from the
magnetron pigtails. Remove the sleeves and discard them. Save the
screws for re-use.
4. Remove the transformer bracket from the wave guide assembly.
