AIR3277 has been reaffirmed to comply with the SAE five-year review policy. 1 FIRMLY SUPPORT THE ITEM TO BE PLUGGED. 2 HOLE A AND PLUG SHALL BE CLEAN AND DRY. 3 INSERT PLUG INTO HOLE A UNTIL IT IS FIRMLY SEATED ON THE SHOULDER AT THE BOTTOM OF THE REAMED HOLE. AN AXIAL LOAD 50–100 LBS OR LIGHT AXIAL BLOWS APPLIED TO A PUNCH WHICH SEATS FIRMLY ON THE BOTTOM OF THE TAPERED HOLE IN THE PLUG, CAN BE USED TO SEAT THE PLUG. 4 PLUG SHALL BE AT LEAST .010 BELOW SURFACE OF THE BOSS. 5 INSERT THE PIN, SMALL END FIRST, INTO THE PLUG. PINS ARE PREWAXED TO AID DRIVING, DO NOT DEGREASE. UNLESS OTHERWISE SPECIFIED, SUPPLEMENTARY LUBRICANT SHALL NOT BE USED. 6 PRESS OR DRIVE THE PIN, USING A VENTED DRIVER UNTIL THE LARGE END OF THE PIN IS .005 ABOVE TO .010 BELOW THE END OF LONG SERIES PLUGS OR .005 ABOVE TO .003 BELOW THE END OF SHORT SERIES PLUGS. 7 VENTED DRIVER DIAMETER: WHEN A HAND ARBOR PRESS IS USED TO INSTALL PINS THE DRIVER DIAMETER SHALL BE LARGER THAN THE PIN BUT SMALLER THAN THE PLUG, THEN THE OPERATOR CAN FEEL WHEN THE PIN IS FLUSH. WHEN A HYDRAULIC OR MECHANICAL POWERED PRESS IS USED WHERE SEATING FORCES CANNOT BE FELT, A DRIVER SLIGHTLY SMALLER THAN THE PIN IS RECOMMENDED AND THE STROKE ADJUSTED TO PRESS THE PIN TO THE FLUSH POSITION. WHEN A HAMMER IS USED, (RECOMMENDED FOR EXPERIMENTAL OR PROTOTYPE INSTALLATION ONLY) A DRIVER SMALLER THAN THE PIN SHOULD BE USED WITH A FEW HEAVY BLOWS (A SERIES OF LIGHT BLOWS WILL TEND TO MUSHROOM THE PIN). 8 DIMENSIONS IN INCHES UNLESS OTHERWISE SPECIFIED. DIMENSIONS APPLY AFTER FINISH.
