In preparation for removing the slave for replacement I discovered that the timing screw in the handle cable drum (master side) had been left threaded into the pulley...it should have been completely removed. It was bent from hitting on a casting inside the mater arm which most likely contributed to the hopped pulleys on the slave side. After removing this timing screw I entered the north hot cell and replaced the hopped cable back onto its pulley and Isaac tested the motions that previous caused the hopped cables. These tasks were repeated 4 times without any issues. Also of note is a missing setscrew in the tong cable pulley pin and a somewhat loose tape on the slave, also the tape shows signs of a crimp/bend. Upon further inspection and comparison with the other slaves I also found that one of the "lock-down" fittings tying the Z motion tape drum to the corresponding gear is completely missing. See pictures attached.
