Hi Antony,
Welcome to the forum from S.Devon.
All I can suggest is that you check the flow control lever on the front of the seat box above the thrpttle pedal. Thie diverts oil from the internal to the external systems. sometimes the lever under the floor will come detached from the rod. It can be refitted with difficulty by reaching under the cab.
Mike is the resident expert on these things !!

Hi Antony

The easy option is if you happen to have a front mounted hydraulic pump driven off the engine front pulley. If so, you can re-pipe through the loader valve first.
With the pump in the rear end the only way both services will work is to modify the pump plate (not a job for the amateur mechanic). I'm not sure why it used to work, as the oil always takes the easiest route which is round the loader circuit.

Mike
