ACTION REQUIRED
The affected engines listed above should be inspected for 6I-2406 tubes assemblies of improper material. The 6I-2406 tube as is used on cylinders 2, 4, 6, 7, 9, and 11 on the G3612 and cylinders 2, 4, 6, 8, 9, 11, 13, and 15 on the G3616. The prechamber fuel lines on these cylinders should be tested with a strong magnet. If the magnet "sticks" to the tube as, the line should be replaced with a new 6I-2406 tube from the parts system. If the magnet does not "stick", the tube should not be replaced.
