Narrative:

I replaced the right nose tire on aircraft. I later realized that I may have left the spacer off of the tire/wheel assembly. The reason for this I believe was that the spacer was never there, and I was confused with the wording in the maintenance manual 767 32-45-02-4 removal/installation paperwork. In this paperwork, 2 different axle types are referenced and according to ipc 767 32-45-02-01M, the axle type that was on this aircraft was not effective per ipc, 32-45-02 page 3 item X. I believe this was a contributing factor.
