Narrative:

The aircraft arrived at the hangar for what we were told a sheared generator shaft. They were holding the trip this airplane was to go on and as soon as we were done it would go. We removed the generator and found the constant speed drive was the problem. We then looked at the logbook and found the real problem was a constant speed drive low oil pressure light came on. After we had the generator and constant speed drive removed, we were told by our management that we did not have a constant speed drive in stock and to put everything together and defer it. Then it was decided to rob a constant speed drive from a spare engine. The maintenance manual states to check the constant speed drive filter. My partner and I got split up. I thought he checked the filter, he thought I did it. The oil filter was not checked. 2 flts later the flight crew got a constant speed drive temperature light going to las. In las it was discovered the oil filter was full of metal. Factors affecting this was misinfo, we were rushed, being split up due to one of us having to go rob a part and mismgmnt.

Title: A B737-300 WAS DISPATCHED IN NON COMPLIANCE WITH A CONSTANT SPD DRIVE AND GENERATOR REPLACEMENT THAT WAS NOT SVCABLE.

Narrative: THE ACFT ARRIVED AT THE HANGAR FOR WHAT WE WERE TOLD A SHEARED GENERATOR SHAFT. THEY WERE HOLDING THE TRIP THIS AIRPLANE WAS TO GO ON AND AS SOON AS WE WERE DONE IT WOULD GO. WE REMOVED THE GENERATOR AND FOUND THE CONSTANT SPD DRIVE WAS THE PROB. WE THEN LOOKED AT THE LOGBOOK AND FOUND THE REAL PROB WAS A CONSTANT SPD DRIVE LOW OIL PRESSURE LIGHT CAME ON. AFTER WE HAD THE GENERATOR AND CONSTANT SPD DRIVE REMOVED, WE WERE TOLD BY OUR MGMNT THAT WE DID NOT HAVE A CONSTANT SPD DRIVE IN STOCK AND TO PUT EVERYTHING TOGETHER AND DEFER IT. THEN IT WAS DECIDED TO ROB A CONSTANT SPD DRIVE FROM A SPARE ENG. THE MAINT MANUAL STATES TO CHK THE CONSTANT SPD DRIVE FILTER. MY PARTNER AND I GOT SPLIT UP. I THOUGHT HE CHKED THE FILTER, HE THOUGHT I DID IT. THE OIL FILTER WAS NOT CHKED. 2 FLTS LATER THE FLC GOT A CONSTANT SPD DRIVE TEMP LIGHT GOING TO LAS. IN LAS IT WAS DISCOVERED THE OIL FILTER WAS FULL OF METAL. FACTORS AFFECTING THIS WAS MISINFO, WE WERE RUSHED, BEING SPLIT UP DUE TO ONE OF US HAVING TO GO ROB A PART AND MISMGMNT.
