April 26, 2004 Crank Position Sensors The running change to crank sensors mentioned in the January 19 Tech Tip was implemented early in March 2004. The new sensors came with a different, gray color, o-ring. The assembly line discovered that the gray o-ring has a tendency to roll during installation. Rolling could cause tearing so a lubricant was temporarily added to the process. We will be eliminating the lubricant and returning to the Teflon coated o-ring, part number 11289A, by May 1.
