An aircraft maintenance technician (amt) reports he could not find specific instructions in the aircraft maintenance manual (amm) to remove and replace (right/right) a cracked lower truck shield on the left main landing gear (medium large transport) of a B767-300 aircraft. He decided to use part of the amm to accomplish the right/right of the shield but realized later he did not remove the brakes and wheels as called out for in previous sections of the amm.

Narrative:
Previous shift found crack in left main landing gear (medium large transport) truck shield. Myself and others were assigned to replace truck shield. [We] could not find specific aircraft maintenance manual (amm) instructions. [We] chose to use part of amm 32-11-18 which specifically talks about shield and electric harness removal and installation (right/I). We did not disturb harness at all. During [shift] turnover there was confusion and not clear direction. After the process I realized the amm previously instructed [removal] of the wheels and brakes and we did not accomplish. Our air carrier [should] provide a repair document for cracks in the shield. Also; provide amm for truck shield replacement.
