TB 9-2300-378-14 CAUTION Take special care to protect air induction system hoses and gaskets from weld spatter. (3) Cut apiece of cardboard at a 60° angle and use it to check angle between No. 2, 3, and 4 grille door and air cleaner box (view A). Grind or weld stop as shown to correct angle. Make area of contact as large as possible to prevent stop from deforming and changing angularity. (4) Check clearances between No. 4 grille door and air cleaner door hinges. Ensure that a clearance of at least 5/8-inch exists (view B). If specified clearance does not exist, grind area on grille door adjacent to air cleaner hinge to obtain specified dimensions. (5) Check No. 3 grille door for 1/8-inch clearance between grille door hinge and air cleaner housing (view C). If incorrect, remove door and adjust clearance by grinding door hinges. Install grille doors. (6) Check No. 2 grille door for 1/8-inch clearance between grille door hinge and air cleaner housing (view C). If incorrect, grind as required to obtain clearance. NOTE Grinding can be accomplished with grille door installed. (7) Clean, prime, and paint all bare metal areas. (8) Connect three battery ground cables. CAUTION Prior to starting engine, check the air cleaner hose clamps for proper installation and that the air cleaner door seal has not been burned during grille door hinge rework. Make sure that the air cleaner door bolts are properly secured. Inspect air inlet and outlet hoses for burns from weld spatter. (9) Start engine, check air cleaner blower motor and restriction indicator operation (TM- 10). 4-47
