Narrative:

Event occurred at the gate. We were working the thrust reverser issue on number 1 engine at the time. During the check-out of the sync locks required for the reverser MEL; I noticed the bolts holding the feedback locking actuator bracket to the outboard upper locking reverser actuator on the reverser were slightly loose; allowing the bracket to move slightly. I took a mental note to check the torque of the bolts after we completed the reverser MEL. As you know this MEL is quite important to do correctly so I was focusing on it 100%. We continued on with the MEL procedures and when nearing completion I let our lead know they were good to start boarding. I ran into a snag safety wiring the outboard turnbuckle and forgot about the actuator bolts until we were back in the break room. I figured the reverser was on MEL so they could be checked when the reverser was being repaired. I asked my lead how to proceed and was told to add information to the MEL trouble-shooting section. I thought that was a good idea so I did. The bolts were only slightly loose and appear they had been that way for awhile. I feel safety of flight was never affected. The bracket is part of the actuator assembly so I feel this is directly related to a reverser MEL item. The next morning I looked the log page up in our maintenance tracking system to see what the fix was. It was then I noticed they cleared the MEL but there was no reference to the loose bolts. I immediately brought this issue to the attention of our maintenance supervisor. Trying to get the plane out with as little delay as possible; I went out to the plane and re-torqued the bolt as required. I determined there were no rigging issues as the bracket and actuator showed no sign of wear. The corrective action was performed on log page; thru flight.

Title: A Maintenance Supervisor; Lead Mechanic and Line Technician report a B737 Thrust Reverser on Number 1 Engine was placed on an MEL and later cleared. A secondary discrepancy for loose bolts holding the reverser feedback locking actuator bracket was missed; even though information had been entered in their Maintenance Tracking Computer System.
