I'm working my way through the AR4. I'm on page 151 of the Robot Manual 1.6 where it says to manually rotate the J5 motor lead screw (to move the J5 carrier inside the housing). I don't understand how this is done. On the previous pages, the J5 housing has retaining compound which locks it unto the shaft. Spinning the J5 motor just spins the lead screw with the J5 carrier together, doing nothing (J4 pulley was disengaged). I had to break the retaining compound and remove the J5 housing-to-shaft set screw to spin the J5 housing to move the carrier.
Now page 152 wants me to rotate the J5 lead screw to verify the carrier trigger the limit switch.
How do you rotate the J5 motor lead screw without breaking the retaining compound and without removing the set screw?
Was it implied that we use pliers on the lead screw to turn it? I don't want to deform the lead screw.
