## Discrepancy

(CAN) AT TIME OF RE-GREASING THE T/R DRIVESHAFT COUPLINGS. T/R DRIVESHAFT WAS REMOVED FROM TUNNEL UNDER ENGINE. FOUND CONTACT WAS MADE WITH TUNNEL AT ENTRANCE DIRECTLY AFT OF TRANSMISSION. SHAFT IS OF NEWER STYLE -011 WHICH IS OF A GREATER DIAMETER THAN THAT OF ORIGINAL.   CONTACT WAS MADE APPROX 1.5 INCHES INSIDE (AFT) OF THE TUNNEL ENTRANCE MAKING THE DETECTION VERY DIFFICULT.  CONTACT WITH TUNNEL WAS VERY MINIMAL & ONLY PAINT WAS MARKED ONE THIRD  AROUND THE DIAMETER OF THE DRIVESHAFT. DAMAGE WAS NOT IN EXCESS OF LIMITS AND PAINT WAS RE-TOUCHED AND DRIVESHAFT RETURNED TO SERVICE.
