## Discrepancy

SERVO FOUND LEAKING FROM TOP AND BOTTOM OF CYLINDER BARREL.  SERVO REMOVED AND REPLACED WITH A SERVICEABLE UNIT.  THE ATTACHED PHOTOS SHOW THE SERVO AREAS THAT HAVE BEEN LEAKING.  THE BULK OF THE OIL HAS BEEN CLEANED OFF THE SERVO, BUT IT CAN STILL BE SEEN WHERE THE LEAKS WERE COMING FROM.
