SUBTASK 72-41-13-380-059 Shot Peen the Heat Shield Mating Diameter
Refer to Figure.
Install the IAE 3P16393 Hanger, Plating 1 off on the threads of the shaft.
Electrical contact is permitted only in the area given in the figure.
In this area no burns, pits or selective attack is permitted.
No plate is permitted in the radii as given in the figure.
Plate outside the area is permitted, but the plate must be removed.
Do the plating procedures given in the SPM TASK 70-33-02-100-501.
NOTE
Do not put the part in an oven before or after chromium plate.Nickel plate the heat shield mating diameter to the maximum plate diameter given in the figure.
