Kondia FV-1 x-feed gearbox questions

Its best if you can narrow down the real problem but as for the gear not being able to disengage under overload, I doubt if that was part of the original design. The slip clutch you repaired is there to handle overloads. Most transmissions with sliding gears are designed so that the angle of the bevel gears pull the gear into position. If they relied on that for overload protection you'd never keep a tractor transmission in gear. The detent on second gear in my old Willies jeep got weak, every time you'd come off the throttle it would pop it into neutral when the load got reversed on the bevel gear. Most trannies now are constant mesh I think with the syncros only engaging a dog clutch type arrangement.
As for the limit stops, you could be right, they may need to be reversed.
Will have to look at the quick change gear box on the Colchester lathe, I think its the same setup as your power feed. If so they run in both directions for carriage and cross feed travel.
