All the open gears need to be cleaned and regreased. Soth center wedge has a 1/8" - 1/4" gap when driven in. Adjust the drive linkage or add shims to the seats to eliminate the gap. Some of the bridge machinery grease fittings have been greased recently, many others have not. Create a list of all the grease fittings on the bridge, and give each point a number and document the location. Go through the list and systematically grease every point on the bridge and document the date in the bridge log book. The East end wedge drive shaft coupling has a lot of lateral movement and is making a clunking sound from the two pieces of the coupling knocking into each other as the drive shaft rotates. Monitor the movement in the coupling. If the condition worsens, replace the coupling. **Update 5/19/20** The worm gear reducer and output shafts are misaligned causing the coupler to pinch at the top and open at the bottom. Align the two shafts. If alignment can not be achieved, replace the coupler with a grid type, or other flexible type coupler that allows for misalignment. **Update 6/03/21** Condition still the same. The Southeast wedge rubs on the Notrheast wedge seat during operation. At this time monitor during operation. Update 9/22/2015: During the inspection, it has been discovered that the Southeast wedge guide mounting bolts were causing the rubbing of the Northeast wedge seat pad. It is recommended that the wedge guide bolts be checked for proper fitment and adjustment be made to allow for additional clearance for skewing operation. **Update 5/19/20** bolts are still rubbing with no adjustment possible. Investigate ways to make the east side of the swing span lighter so not as much deflection occurs. Possibly replace the damaged deck section with lightweight concrete. **Update 6/3/21** clearance still the same.
