4. Procedure
_________ Subtask 24-21-00-210-059-A
A. Visual Inspection
(1) Do a visual inspection of these components:
NOTE : There can be different signs of possible leakage:
____ -Droplets of oil
-Wet areas around connections, oil stripes on tubes
-Stains or discoloration which can occur when oil or grease is in contact with very hot surfaces.
1EFF : ALL 1 24-21-00Page 611 1 1 Aug 01/05R 1 1 1CES 1
(a)
IDG fittings for leakage:
-Pressure fill port
-Overflow drain port
-Oil-in and oil-out ports (cooling circuit interface with the IDG)
-Case drain. If you find an oil leak, replace the related fitting.
(b)
External oil circuit (oil lines) for leakage and correct condition:
1_ Tubing
- No cracks are permitted on tubes, hoses and tube coupling
nuts.
- There is no limit for the number of nicks and scratches if
the depth is not more than 0.25 mm (0.0098 in.) (after
removal of the high metal).
- Two dents for each tube are permitted if they are of a
smooth contour up to 1.27 mm (0.0500 in.) depth.
You must replace all tubes or hoses that are not in these
limits.
2 Attachment
_
-
Replace broken or cracked brackets.
-
Replace worn clamps.
-Install missing nuts and bolts.
-Tighten loose nuts and bolts.
(c) IDG oil cooler for leakage:
-Oil-in and oil-out ports (cooling circuit interface with the cooler)
-Drain plug
-Body of the cooler. If you find a leak, replace the IDG oil cooler (Ref. TASK 73-11-60-000-002) and (Ref. TASK 73-11-60-400-002).
(2) If you find components wet with oil, make sure that you find and correct all the causes. If necessary, fill the oil tank (Ref. TASK 12-13-24-612-041).
