A B737-300 MAY HAVE BEEN RETURNED TO SVC WITH THE STABILIZER TRIM CABLES TENSIONED WITH THE INCORRECT TOOL SETTING.

Narrative

I WAS WORKING ON ONE OF THE DAYS BTWN JAN/SAT/05 AND JAN/SUN/05 AND WAS WORKING ON A NON ROUTINE. THE NON ROUTINE STATED THAT 2 EACH CABLE PULLEYS FOR THE STABILIZER TRIM CABLE WERE CHANGED AND THAT THE TENSION HAD BEEN BROKE. I WAS TO RE-TENSION THE CABLES. I PULLED UP THE MAINT MANUAL AND CHKED WHAT THE TENSION SHOULD BE (AT 70 DEGS IT SHOULD BE 130 LBS AND USE A #1 RISER). I TENSIONED THE CABLE; SAFETIED AND SIGNED IT OFF. ON JAN/SAT/05; I WAS WORKING AN EVENING SHIFT. THERE WAS A MECH DOING THE SAME JOB I HAD DONE. I WENT UP TO HIM AND SAID 'BE SURE TO TENSION THE CABLE AT 70 DEGS; 130 LB AND #2C RISER;' WHICH IS WHAT I REMEMBER DOING. HE SAID 'NO; IT IS A #1 RISER.' THAT IS WHEN I STARTED TO THINK. I KNEW IT WAS SUPPOSED TO BE A #1 RISER; BUT I REMEMBER USING A #2C. ONCE I RECALLED THIS; I FILED A RPT. I NOTIFIED ASRS RPT REPRESENTATIVE WITHIN 1 HR OF DISCOVERING MY MISTAKE. I CALLED MAINT CTL AND TALKED WITH TEAM LEAD AND DISCUSSED HAVING THE CABLE TENSION RECHKED. HE TOLD ME IT WOULD BE A ROUTINE OVERNIGHT CHK AND HE WOULD HAVE THE TENSION CHKED THEN.
