I recently purchased a Newton Claw but unfortunately the wire that comes with it is too short for my application. I know the claw is supposed to be a sort of black box but I would like to ask you guys how difficult it would be to remove the alan bolts on the end cap and replace the shorter wire with a longer one. Im assuming that I would need to replace the wet link seal at that moment as well.
I don’t expect that should be particularly difficult. We sell the cable by the meter, but if you’re extending it quite a bit I’d recommend checking our Voltage Drop Calculator to ensure the cable can provide sufficient power. The internal ESC uses the same insulation displacement connectors as our Lumen PCBs, so your replacement may not even require soldering:

It’s possible that the most involved part of the cable replacement would be replicating the connections on the inside of your electronics enclosure, although you may be able to re-use the existing connectors by cutting off short lengths of the existing wires and splicing them onto the ends of the new cable wires.
Do take care to keep the o-rings clean when disassembling/reassembling, to avoid creating a leak point
I have just replaced the motor and the pcb of my arm (an R2), I was very scared but in the end it was relatively simple … and I even took the opportunity to do a complete overhaul of the arm (my breakdown was due to water leak following a small crack on the cable!!)
I disassembled all the internal components (it’s easy), cleaned everything, put silicone grease on the joints and reassembled everything.
It took me (working very slowly) one morning.
