HINGE REPAIR AND REPLACEMENT

THE HINGES ON WATERTIGHT DOORS, PARTICULARLY THOSE ON QUICK ACTING ONES, SUFFER A LOT OF WEAR AND TEAR.  EVENTUALLY, HINGES WEAR OUT AND REQUIRE MAJOR REPAIR OR REPLACEMENT.


THE BASIC PROCEDURE FOR HINGE DISASSEMBLY AND REPAIR

  1. WITH A HAMMER AND CHISEL, KNOCK THE HINGE PIN COLLARS OFF THE BOTTOM OF THE HINGE PINS.

  2. USING A FLAT TIPPED DRIFT PUNCH, DRIVE OUT THE HINGE PINS.  IF THE HINGE PINS ARE BADLY WORN, YOU MAY NEED TO HAVE A SECOND PERSON LIFT THE DOOR FROM THE BOTTOM AND ROCK IT BACK AND FORTH SO YOU CAN DRIVE OUT THE PINS.

  3. SET THE DOOR PANEL ASIDE WITH THE HINGE SIDE UP.

  4. TAKE APART THE ADJUSTING PIN AND YOKE OF EACH HINGE ASSEMBLY.  (ON A QUICK ACTING AIRTIGHT DOOR, THE HINGE ASSEMBLY IS MORE COMPLEX BECAUSE ITS ADJUSTING YOKE MUST HOLD THE HINGE SIDE OF THE DOOR IN PLACE.  THERE ARE NO DOGS ON THE HINGE SIDE OF AN AIRTIGHT DOOR.)

  5. CLEAN ALL THE PARTS AND EXAMINE THEM FOR WEAR SO EXCESSIVE THAT THEY MUST BE REPLACED.  WHEN REPLACING HINGE PINS ON STEEL OR STAINLESS DOORS, CONSIDER USING BRASS PINS THAT DO NOT WEAR OUT HINGE YOKES AS FAST.

  6. REASSEMBLE THE ADJUSTING YOKES AND PINS ON THE HINGE BLADES.  BE SURE TO INSERT A 1/8" THICK BRASS FLAT WASHER ON TOP OF THE BOTTOM ADJUSTING YOKE BLADE BEFORE INSERTING THE ADJUSTING PIN AND COTTER PIN.

  7. SET THE DOOR IN THE FRAME.

  8. PLACE THREE 1/16" THICK BRASS FLAT WASHERS BETWEEN THE TOP OF THE HINGE PAD AND THE LOWER ADJUSTING YOKE LEAF.

  9. INSERT THE HINGE PINS.

  10. CLOSE AND DOG THE DOOR.

  11. CHECK TO SEE THAT THE KNIFE EDGE SITS IN THE CENTER 3/5 OF THE WIDTH OF THE DOOR GASKET AT THE TOP AND BOTTOM OF THE DOOR.  ADD OR REMOVE 1/16" BRASS WASHERS AS REQUIRED TO VERTICALLY CENTER THE DOOR.

  12. FOR EACH HINGE PIN, HOLD THE TOP IN PLACE BY RESTING A SLEDGE HAMMER ON IT.  INSERT THE COLLAR, BEVEL SIDE DOWN.  PEEN OVER THE BOSS WITH A BALL PEEN HAMMER TO LOCK THE COLLAR TO THE HINGE PIN.
