Hi,

Crossing cables are always a big problem with the IIIa arms. I had similar problems and could not really solve it.
So I just checked almost every working day and adjusted them when they got out of line.
I guess it is something you have to live with.
I think you can put something like LockTite between the inserts and the springs but I doubt if it helps. The flex and forces in the springs are so high that it is not likely to work.

But keep checking, if you neglect it you will ruin the plastic coating of the cables and possible the pullies will be damaged by the steel core.

Hi Guys

Cable crossing is often caused by either wear or lack of lubrication on the adjuster screws (the screw can actually get bent as well). The worst result will be the pulley wheels cutting into the plastic coating of the cables and maybe even damaging the steel cable strands so check this regularly.
