The range P units are sealed for life and not suited for economic repair. They should be replaced instead. The Range-N and Range-U can be repaired or spares fitted, although it is worth noting that if all internal components need replacing then it would be cheaper to purchase new units. If units need repairing we would recommend returning them to the factory, where they can be rebuilt with the correct backlash and alignment.

When disposing of gearboxes and lubricant please do so in an environmentally responsible manner.
