Top Deck Grille Door Rework (CONT)

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).
