Installation Procedure


    Object Number: 206451  Size: SH
  1. Install a new gasket to the ether capsule so the gasket rests at the bottom of the capsule neck.
  2. Only use one gasket. Spread a light film of clean oil on the gasket.

  3. Turn the new ether capsule in a clockwise rotation until the capsule contacts the gasket in order to install the new ether capsule.
  4. Important: 

       • Ensure that the capsule has been threaded in the control valve correctly and tightened properly.
       • The gasket may inhibit observation of leakage caused by an improperly installed capsule.

  5. Tighten the ether capsule another half turn (180 degrees). Do not overtighten the ether capsule.
  6. Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

  7. Tighten the ether capsule bracket clamp.
  8. Tighten
    Tighten the ether capsule bracket clamp to 2 N·m (18 lb in).
