A. Do the operational test of the Yellow electric pump (Ref. AMM TASK 29-24-00-710-001).
4. Fault Isolation
_______________
A. If the test gives:
R (1) Fluctuation of the hydraulic pressure: R - Refer to (Ref. TASK 29-24-00-810-801). R
R (2) The ELEC PUMP-Y (3075GX) operates but supplies no hydraulic pressure: R
R (a) Remove the ELEC PUMP-Y (3075GX) (Ref. AMM TASK 29-24-51-000-001). R

R (b) Examine the:
- coupling shaft (Ref. CMM 29-21-21) and
- inner components (Ref. CMM 29-20-28) or (Ref. CMM 29-21-20)
of the ELEC PUMP-Y (3075GX) for damage.
R
R (c) If you find damage:
R
R 1_ Remove the CHECK VALVE- ELEC PUMP DELIVERY, Y (3083GM) (Ref.
AMM TASK 29-24-21-000-001).
R
R 2_ Do a visual inspection of the CHECK VALVE- ELEC PUMP DELIVERY,
R Y (3083GM) for damage and missing parts.
R
R 3_ If parts are missing, do the subsequent before you install the
R new check valve:
- Examine the Yellow HP filter (3048GM) (Ref. AMM TASK 29-13-
45-610-001) and the Yellow HP manifold (Ref. AMM TASK 29-13-
14-000-001) and (Ref. AMM TASK 29-13-14-400-001) to find
these parts.
R
R 4_ Install the CHECK VALVE- ELEC PUMP DELIVERY, Y (3083GM) (Ref.
AMM TASK 29-24-21-400-001).
R
R 5_ Replace the ELEC PUMP-Y (3075GX) (Ref. AMM TASK 29-24-51-400-
001).
5. Close-up________
A. Do the test as given in Para. 3. A. to make sure that the operation is
correct.

__________________
A. Do the operational test of the Yellow electric pump (Ref. AMM TASK 29-24-00-710-001).
4. Fault Isolation
_______________
A. If the Yellow electric pump starts to operate and stops after some seconds during the operational test:
- Do a check of the red indicator light on the phase unbalance detector (3808GX).
(1) If the red indicator light on the phase unbalance detector (3808GX) is on:
- Replace the CT-Y ELEC PUMP (3807GX) (Ref. AMM TASK 29-24-15-000-001) and (Ref. AMM TASK 29-24-15-400-001).
(2) If the red indicator light on the phase unbalance detector (3808GX) is not on, or the fault continues after replacement of the CT-Y ELEC PUMP (3807GX): 中国航空网 www.aero.cn 航空翻译 www.aviation.cn 本文链接地址：A320 Trouble Shooting Manual 排故手册 液压(98)
