ODU Connector Cleaning

The P-Port receptacle must be cleaned and lubricated on each of the system P-ports (P1 and P2 on the LPCA and P3 and P4 on the 32-channel table). Also, the coil connector must be cleaned and tested for proper fit to each P-port receptacle.

Procedure

    Notice Image
    • notice
    • Use only the cotton swabs provided with the P-Port Spindle Lubrication Kit to clean the spindle tip. Clean with a dry swab. Do not use alcohol or cleaning products when cleaning the spindle tip. Do not apply any lubricant to the spindle tip. Avoid bending any pin contact.
  1. Use the cotton swabs included in the P-Port Spindle Lubrication Kit to clean the spindle tip on the coil connector of each coil on site, removing all dirty lubricant and dust particles from the spindle tip, especially from the groove. (See the illustrations below.)

    2. Notice Image
    • notice
    • Make sure to inspect the lubricant expiration date prior to use. Do not use out of date material.
  2. Clean and lubricate all the system P-port connectors as shown below.
    note:

    Special lubricant (included in the P-Port Spindle Lubrication Kit) and cotton swabs are required for cleaning and lubricating the P-port receptacle on the scanner.

    Figure 5. Location of Pins in P-Port Receptacle

  3. During the cleaning process, inspect the receptacle contact surface and remove any debris.
  4. After all the P-Port connectors are cleaned and lubricated, cap and store the syringe with any unused portion in the original labeled packaging for future use. Assure the outer packaging is clean of lubricant, remove the protective gloves, and wash your hands to remove any lubricant residue.
  5. Cap and store the syringe with any unused portion in the original labeled packaging for future use.
  6. After the syringe is empty or has an expired date code, dispose of the syringe according to the SDS provided with the kit.

Coil Plug Connector Spindle Replacement

Follow this procedure to replace the spindle tip on the DVMR coil connector.

Procedure

    Notice Image
    • notice
    • The new spindle contains beryllium copper and is nickel plated. Wash your hands thoroughly after completing this procedure.
  1. Move the coil with the defective spindle to a suitable location outside of the Magnet Room.
  2. Confirm that all components (shown below) are included in the HDv P-Port Replacement Spindle Tip Kit.
    note:

    Counter Sunk Screw is 8 mm long and has a red coating. A hexagonal socket is required.

    Figure 6. Spindle Tip and M3 Counter Sunk Screw

  3. Place the unpopulated connector found in Spindle Tip Replacement Tool kit (5150668-33) into the coil plug connector, and rotate the handle clockwise to lock the position as shown.

    Figure 7. Placing Unpopulated Connector into Plug

    Figure 8. Rotating Unpopulated Connector to Lock in Position

  4. Using the T10 Torx or a 2 mm Allen wrench, loosen the screw on the unpopulated connector (as shown) with only one rotation counterclockwise.

    Figure 9. Loosening Screw on Unpopulated Connector

  5. Remove the unpopulated connector from the coil plug connector.
  6. Loosen and remove the screw from the plug using either the T10 Torx or a 2 mm Allen wrench as shown. Discard the screw.
    note:

    The screw from the plug must not be reused. If the screw is reused, it may loosen and the spindle may fall off.

    Figure 10. Removing Screw from Plug

  7. Replace the spindle tip and the counter sunk screw, and turn the screw using a 2 mm Allen wrench, but do not tighten.

    Figure 11. Spindle Tip and Screw Replaced

  8. Place the unpopulated connector into the plug again, and rotate the handle clockwise into the locked position as shown in Figure 7 and Figure 8.
  9. Hand tighten the screw, and turn it an additional 1/10 turn (1.24 Nm) with the 2 mm Allen wrench as shown.

    Figure 12. Tightening Screw in Unpopulated Connector

  10. Remove the blank P-port plug, and save the plug and Torx bit driver for future use.
  11. Dispose of the removed parts according to the SDS provided with the parts kit.

Finalization

Finalization

  1. Verify that all of the customer’s coils connect properly to all of the customer's system-side connectors.

  2. If you replaced a spindle, run the appropriate MCQA test for the repaired coil.
