Check balancing arms and trailing horizontal hinge pins bearing caps for proper markings.  If the letter "H" is visible, go to step 4.  If the letter "H" is not visible, proceed as follows: a. Mark each of the balancing arms (1) and adjacent areas of the horizontal hinge pin bearing caps (2) as shown in figure.  Use reflective tape (E397). b. Clean the trailing face of the arm with cloths (E120) dampened with solvent (E162). Wear gloves (E186).  Also, clean the trailing horizontal hinge pin bearing cap face area. c. Cut three strips of reflective tape (E397), two  4 inches  long and one  3 inches  long. Place one  4 inch  long strip just to the left (outboard) of the bolt insert point for the torque wrench socket tool (T5), centered between the top and bottom of the bearing cap. Starting from the inner area, place the  3 inch long strip to form half the "H", the tape will run long enough to cover the outside lip of the bearing cap.  Next, attach the remaining 4 inch long strip on the balance arm trailing face to complete the letter "H". d. Repeat the steps above for the remaining balance arms and bearing caps. Change 2 5-229
