A.Refer to Figure 901 for specified dimensions and locations.
NOTE:
The dimensional data identified within this procedure was designed using inches as the base unit of measurement for dimensional values. The conversion to millimeters is rounded to one less decimal digit than inches. For minimum dimensions, converted values are rounded up. For maximum dimensions, converted values are rounded down. To avoid conversion errors, do not re-convert from millimeters to inches.
NOTE:
Reference dimensions do not require inspection.
4 . Setup Information.
None.
5 . Procedure.
Subtask 72-00-52-350-001
A.Blend the nozzle tack welds to remove the vane sleeve from the nozzle. Refer to TASK 70-42-00-350-002 (BLENDING AND REMOVAL OF HIGH METAL PROCEDURES), Figure 901, and as follows:
(1)Pull the vane sleeves out with pliers.
Subtask 72-00-52-350-002
WARNING:
USE EYE PROTECTION WHEN YOU USE COMPRESSED AIR TO CLEAN, COOL, OR DRY PARTS OR TOOLS. PARTICLES CAN CAUSE AN INJURY TO YOUR EYES. ENSURE COMPRESSED AIR PRESSURE IS LESS THAN 30 PSIG (207 KPA). DO NOT POINT COMPRESSED AIR AT YOURSELF OR OTHER PERSONS.
B.Use dry shop air to remove unwanted material from the nozzle cavities.
Subtask 72-00-52-350-003
C.Install the new vane sleeve on the nozzle. Refer to paragraph 2.E., Figure 901, Figure 902, and as follows:
(1)If necessary, blend to remove the aluminide coating from the tack weld areas of the nozzle. Refer to TASK 70-42-00-350-002 (BLENDING AND REMOVAL OF HIGH METAL PROCEDURES).
(2)Install the new vane sleeve flange against the nozzle surface.
(3)The maximum clearance permitted is 0.005 inch (0.12 mm) and as follows:
(a)The average clearance permitted is 0.003 inch (0.07 mm) maximum.
Subtask 72-00-52-310-001
(4)Weld the vane sleeve to the nozzle with C06-051   L605 weld wire. Refer to TASK 70-41-00-310-001 (WELDING AND BRAZING PRACTICES) and as follows:
(a)Blockage of the cooling holes because of welding is not permitted.
Subtask 72-00-52-220-099
D.Do an inspection of the nozzle. Refer to TASK 72-00-00-200-805 (72-00-00, INSPECTION 001).
