Gear extended by using alternate system per QRH. Landing was not overweight. Landing gear monitored EICAS status. Corrective action was to adjust and replac hardware for main gear door sequence valve per aircraft maintenance manual (amm) 32-32-08; operational checks normal. I was the inspector on the B767-300 aircraft six-days earlier; when maintenance had performed landing gear changes. On [job card] step-8; (A-7r). It has you install the bolt; bushing; washers and nut between the turnbuckle and the spindle washer. All of these items were installed at time of inspection. The aircraft job card should have a note telling the importance of this hardware.
