SUBTASK 72-41-00-440-140 Do the HP Compressor Front Case VSV Clearance Checks (SBE 72-0402)

SBE 72-0402: HP compressor variable vanes - inlet guide vane and stages 3 to 6 with optimised build and setting instructions.

Refer to: Figure and Figure
NOTE
The SUBTASK references which follow are in TASK 72-41-30-440-011-A00 (ASSEMBLY-011, CONFIG-001).
1. During the clearance checking procedure it could be necessary to lubricate the applicable areas of a particular stage of the VSV mechanism. Use CoMat 10-108 HIGH PERFORMANCE PENETRATING LUBRICANT WITH TEFLON (R), refer to TASK 72-41-30-440-011-A00, SUBTASK 72-41-30-440-208.

Measure the clearance for each stage between each centralizing pad, compensating block housing pad and the contact surface of the HP compressor front case.

Install all the build pins for each stage, refer to SUBTASK 72-41-30-440-206. The build pins must stay in the installed position throughout this procedure for each stage in turn.
Measure and make a record of the clearance and the location of each stage. During the procedure the feeler gauge(s) must stay in position as each stage is checked in turn. A clearance of zero is acceptable.
NOTE
If you check the clearance with a feeler gauge in an axial position it will give large errors.
Use feeler gauge(s) between each pad and circumferentially along the length of the actuating ring. Use the positions for the feeler gauges given in Figure for the left side of the HP compressor case and Figure for the right side of the HP compressor case.
Check the clearance at the next circumferentially adjacent pad and the remaining pad clearances until all the eight pad clearances are measured for each stage. Use the procedure in Step or Step.
Add the eight clearances for each stage and refer to the limits below which gives the total clearance for each stage and for each maximum clearance.
NOTE
The procedure to set the pad clearances is given in TASK 72-41-30-440-011-A00, SUBTASK 72-41-30-440-207.

If the clearances for each stage are more than the limits given in the following table of limits (Table 1) then the particular connector must be removed and the actuating ring must be checked for misalignment marks. Refer to the checking procedure for the correct installation of the dowels given in TASK 72-41-30-440-011-A00, SUBTASK 72-41-30-220-445.

If marks are seen then it could be possible to meet the limits in table 1 by re-installing the connectors and rechecking the clearances. Use the above procedure to re-check the clearances so they are within the limits of table 1.

If marks are not seen then the stage must have the pad clearances reset from the start of the procedure, that is, as given in TASK 72-41-30-440-011-A00 (ASSEMBLY-011, CONFIG-001).
