NONEProcedure
Refer to Figure.
Machine the diameter to permit a minimum plating thickness of 0.002 in. (0.051 mm) after finish machining.
Hold to the minimum value.
If the diameter was plated before, you can strip the plating.
Refer to the SPM TASK 70-33-05-300-503.
Machine the ID of the seal spacer.
SUBTASK 72-50-42-320-051 Machine the ID of the No. 5 Bearing Seal Spacer before Nickel Plate
Refer to Figure and the SPM TASK 70-33-06-330-503.
Apply nickel plate to a sufficient thickness to permit finish machining.
Plating outside the repair area is permitted but must be removed.
Nickel plate the ID of the seal spacer.
SUBTASK 72-50-42-330-051 Nickel Plate the ID of the No. 5 Bearing Seal Spacer
Refer to Figure and TASK 72-50-42-200-000 (INSPECTION/CHECK-000).
Do a visual inspection of the plated area to examine for cracks and adhesion.
Use a 4X magnifying glass to examine for cracks.
The normal network of cracks that is emphasized by grinding is permitted.
The thickness of the plate after finish machining must be a minimum of 0.002 in. (0.051 mm).
Examine the seal spacer after nickel plate.
