Narrative:
A B767-300 aircraft was out of service due to #2 engine bleed issues. Grave shift had swapped the pressure regulating valve (prv) and the high pressure shut-off valve (hpsov); however; they were no help. Grave shift lead mechanic then ordered a prv controller. Controller [was] not in stock in ZZZ; so the out of service desk procured a controller from another air carrier in ZZZ.technician installing [hpsov] controller mentioned that controller that came off was a XXX-16 and the installed replacement controller was a XXX-15. I said that I would verify part effectivity. However; immediately after installation; we ran the engine and had to continue troubleshooting due to fault not clearing completely. I did not verify the part number after that point. Two days later; I was informed that the controller that was installed was the incorrect part. The correct part was installed by ZZZ1 company maintenance approximately two days later. Although I did not install the controller and did not short-sign the logbook; I will take complete responsibility for the incorrect part being installed.
Original NASA ASRS Text
Title: A Lead Mechanic and Line Mechanic were informed that a High Pressure Shut-off Valve (HPSOV) controller borrowed from another air carrier was not effective for the PW-4000 engine on their B767-300ER aircraft. The borrowed controller came from a GE CF-6 engine; but was physically interchangeable.
