It was nothing serious,the shaft that linked the electric motor to the hydraulic pump snapped.
It came as part of the electric motor so it wa sa case of replacing the motor or having a new part made.
We opted for fabricating a new part but that meant the lift was out of action for nearly a week.
It was inconvenient at first, then mildly irritating as the boss' dad kept asking when it would be back in service.
The new part arrived and was fitted, the hydraulic pump was bled and returned to active duty and... the boss' dad commandeered it to make and paint a pair of gates :-/
