Previous shift found crack in Left Main Landing Gear (MLG) 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 (R/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.
An Aircraft Maintenance Technician (AMT) reports he could not find specific instructions in the Aircraft Maintenance Manual (AMM) to Remove and Replace (R/R) a cracked lower Truck Shield on the Left Main Landing Gear (MLG) of a B767-300 aircraft. He decided to use part of the AMM to accomplish the R/R of the shield but realized later he did not remove the brakes and wheels as called out for in previous sections of the AMM.
