Procedure

    1. SUBTASK 24-21-49-350-052 Prepare the Tube Wall

      CAUTION

      DO NOT PULL THE MANDREL WITH TOO MUCH FORCE. THIS CAN CAUSE DAMAGE TO THE TUBE AND CAN CAUSE THE MANDREL TO BE CAUGHT IN THE TUBE.

      1. Put the lanolin lubricant in the oil cooling tube.

      1. If there is an access, apply the lanolin lubricant directly on the damaged area.

    2. Put the oil cooling tube in the jig.

      3. Put the mandrel into the oil cooling tube.

      1. Refer to Figure. Make sure that there is a bead of lanolin lubricant in front of the mandrel during the repair. Feed the cable of the mandrel through the oil cooling tube.

      4. Repair the tube wall.

      1. Pull the mandrel through the oil cooling tube until it touches the damaged area. Pull the mandrel through the damaged area without too much force. If necessary, hit the damaged area lightly with the nylon hammer as the mandrel goes through the damaged area. This will help to move the mandrel.

    5. Remove the mandrel from the oil cooling tube.

    2. SUBTASK 24-21-49-110-055 Clean the Oil Cooling Tube

      WARNING

      DO NOT GET THE CLEANING FLUID ON YOUR SKIN OR IN YOUR EYES. PUT ON PROTECTIVE CLOTHING, GLOVES, GOGGLES AND A MASK. USE THE FLUID IN A CORRECTLY VENTILATED AREA. DO NOT BREATHE THE GAS. IF YOU GET THE FLUID ON YOUR SKIN OR IN YOUR EYES, FLUSH IT AWAY WITH WATER. GET MEDICAL AID IF YOUR SKIN OR EYES BECOME IRRITATED.

      1. Clean the tube.

      1. Use the CoMat 01-076 METHYL ETHYL KETONE and the CoMat 02-099 LINT-FREE CLOTH. Remove the lanolin lubricant with the fluid. Make the tube clean with a clean piece of lint-free cloth before the fluid dries.

    3. SUBTASK 24-21-49-220-001 Examine the Oil Cooling Tube

      1. Examine the oil cooling tube.

      1. Make sure that the repairs are satisfactory. Cracks and distortion are not permitted. The shape of the tube must be parallel in the internal diameter and the external diameter.

    4. SUBTASK 24-21-49-230-058 Examine the Oil Cooling Tube

      1. Do a dye-penetrant test on the oil cooling tube.

      1. Refer to SPM TASK 70-23-00-230-501.

    5. SUBTASK 24-21-49-780-001 Pressure Test the Oil Cooling Tube

      1. Do a pressure test on the oil cooling tube.

      1. Refer to Testing-001 TASK 24-21-49-700-101.

    6. SUBTASK 24-21-49-850-052 Put the Repair Scheme Number on the Oil Cooling Tube

      1. Mark the repair scheme number VRS2800 on the oil cooling tube adjacent to the part number, with an electro-etch method.

      1. Refer to SPM TASK 70-09-00-400-501.
