Subject: manipulator cart repair 

A  hydraulic leak was found on the manipulator  install and repair cart, upon further investigation the cause was a faulty cylinder. Once the cylinder was removed and disassembled the inner bore was found to be scored beyond repair. Another point of interest was that the rod was painted to the point that when retracted it compromised the rod seal causing the cylinder to leak. attached are photos outlining the issues. new cylinders are being sourced and will be installed upon arrival. We have found that there is interaction between the tops of the cylinders and the bed of the cart when fully retracted and compressed, this might require some modifications to ensure proper operation in the future.
