Narrative:

I installed the incorrect vibration monitor due to some confusion that the maintenance manual created because it shows that all different types of vibration monitors can be installed on the B767-300ER. The only solution for this problem that I can come up with is to remove all the information in the maintenance manual that refers to the effectivity of the tail numbers. The ipc should have all jurisdiction as to what parts belong on the correct tail number aircraft. I have submitted a change request to the manual department. I took a verbal turnover from the outbound crew that they encountered a vibration problem on taxi in. I put the write-up in the logbook and looked up the history of the aircraft. The aircraft had encountered one previous problem. I decided to change the vibration monitor after I had inspected the engine and all of the wiring and sensors. I did not detect any problems in any of the system. I looked the part up in the ipc and pulled up the maintenance manual. I ordered the part and installed it. I placed the vibration monitoring system on maintenance carry over. I signed the airworthiness release and released the aircraft. After departure; I was informed that the part effectivity did not match the aircraft.
