Narrative:

Pushback mechanic in xyz on may/xx/97, noticed nosewheels didn't look right. After removal and replacement of nosewheels discovered bearings were of wrong type. This aircraft was in service approximately 1 month with this condition. I work in the tire shop in ZZZ and may have had a part in this incident. I believe closer attention to part numbers would solve this problem. The bearings involved were B737- 200 main PN27690 and A320 nose PN42690H both having approximately same outside diameter.
