I have cable controls on the 4 section spool valves of my loader: With 4 functions, its a lot of oil lines and heat inside the cab.
I have no problems with the bowden cables, except for the hook that hooks into the lower end of the lever, sometimes breaks off and needs to be welded. The cables themself operate flawless, with lots of WD 40 sprayed into them as preventative measure.
My cables hang in a U shape from levers, underneath the floor, to the spool valves in front of the cab, so the WD 40 doesnt drip out...
