3.
Check for clearance between lugs (4) and hub
(5) (Task 5-52).
3.1.
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.
