Narrative:

I was working aircraft xyz #1 engine fan change. After disassembly, the inspector wrote a north/right (non routine write-up) card requiring replacement of the #1 bearing. I ordered a bearing from stores using what I thought to be the correct part number from the fan change training manual. I failed to verify part number and effectivity per the ipc. At the time of turnover to the next shift, the bearing was en route from stores. The relief crew installed the bearing that I had ordered. Engine records department subsequently discovered the discrepancy, at which time the aircraft was grounded for rework of the #1 engine #1 bearing. I believe this problem can be prevented in the future by eliminating part numbers from training manuals.
