3. Job Set-up
__________
NOTE : A cavitation condition of the engine pump is possible when the engine
____ pump operates with the engine pump fire valve closed (if you set the ENG 1 (2) FIRE pushbutton on the Eng/APU fire panel), or with the reservoir below the low level (ECAM indication).
Subtask 29-00-00-860-078
A. There is no special job set-up for this task.
4. Procedure
_________
Subtask 29-00-00-281-051
A. Do a check of the engine pumps for a possible cavitation condition
R R R R R NOTE : Two procedures are included here to do a check if the engine pump____ has operated for more than 5 minutes in a possible cavitation condition. Each procedure is applicable for a different set of conditions. Only do the procedure that is applicable for the conditions you find.
R R R R (1) Do the subsequent procedure if the engine pump has operated for more than 5 minutes: - With a closed engine pump fire valve - With the RSVR LO LVL warning on the upper ECAM DU and the fluid index below the minimum gaugeable level on the ECAM HYD system page.
R R NOTE : There are no time limits if the engine pump is set to OFF (ENG____ 1 (2) PUMP FAULT/OFF pushbutton on panel 40VU) with the engine-pump fire valve open and the fluid level of the reservoir above the low level.
(a) Replace the related engine pump (Ref. TASK 29-11-51-000-040) and (Ref. TASK 29-11-51-400-040) or (Ref. TASK 29-13-51-000-003) and (Ref. TASK 29-13-51-400-003).
(b) Do the operational test of the related hydraulic system (Ref. TASK 29-11-00-710-001) or (Ref. TASK 29-13-00-710-002).
R R R 1_ During the test, slowly move only one flight control surfaceat a time. Do this to prevent a pressure decrease to less than 2800 psi (193.0531 bar).
(c) Do a check for particles in the filter bowl and the filter of the hydraulic control unit of the thrust reverser.
R R R 1_ If you find particles:- Replace the filter element (Ref. TASK 78-31-51-920-040). - Flush the related hydraulic system (Ref. TASK 12-36-29-170-001) or (Ref. TASK 12-36-29-170-002).
R R (d) Do a check for particles in the case-drain filter bowl and the filter of the related engine pump.
R R R R 1_ If you find particles:- Replace the filter element (Ref. TASK 29-11-43-610-040) or (Ref. TASK 29-13-43-610-040). - Flush the related hydraulic system (Ref. TASK 12-36-29-170-001) or (Ref. TASK 12-36-29-170-002).
(e) Do a check for particles in the HP filter bowl and the filter of the related system.
R R R R 1_ If you find particles:- Replace the filter element (Ref. TASK 29-11-45-610-001) or (Ref. TASK 29-13-45-610-001). - Flush the relevant hydraulic system (Ref. TASK 12-36-29-170-001) or (Ref. TASK 12-36-29-170-002).
(f) Do the steps (b) thru (e) again, until all particles are removed.
R R R (2) Do the subsequent procedure, if the engine pump has operated for more than 5 minutes: - With the RSVR LO LVL warning on the upper ECAM DU and the fluid index above the minimum gaugeable level on the ECAM HYD system page.
