Pete Dudley, manipulator service technician from CRL, was on site from Nov 27-30 to service the NHC Model N manipulators (See E-log entry #1578 for background).
He began by evaluating the motion selection and electric drive of the manipulator installed on the blue service cart. This manipulator had
chip A0166R01, same as the right side manipulator which had the failure described in E-Log 1578. Pete noted that the arm was very slow to switch |

|
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 |
