And your stuck with this because the oil pump doesn't work if you reverse the motor so that "down" is forward.
I don't think that is true that you are stuck with currect directions the joystick gives - by reversing the wires to the microswitches on the joystick, the direction should also reverse for the physical position of the joystick. That said, I believe the wires are crimped together (two wires going to a single position on the terminal strip at the bottom of the control panel), so these would have to be cut apart and reconnected or the joystick pulled and the wires reversed there.....
No changes to the motor direction so the oil pump is fine - in effect, the reconnection proposed above activates the reverse clutch when the joy stick goes up and the forward clutch when it goes down (instead of the opposite as it is now).
Maybe this is a good place to ask: does reverse sound different and louder on your machines than forward? Mine does and I suspect it is because reverse goes thru the extra gear mounted to the front panel..... Comments?
BTW, the clutch on my Colchester is also up for forward.
Mechanical clutch so you can't switch wires. Sounds about the same for or rev.
Mechanical clutch? I guess I have forgotten what a 180 is.... In that case, you would need to dream up and make a new mechanical linkage for the clutch that reverses the positions.....
Alternatively, rework the pump passages in its faceplate (or wherever) so it pumps in the opposite direction and reverse the motor - where there is a will there is a way.....
If you are going to use a VFD to slow down the main motor, you may need to use a separate motor for the pump (as I did on my Colchester) so the main bearings get sufficient oil when the main motor is running slowly.
The part at upper left (1910/d-1) is what shifts the clutch. If you were keen maybe you could make a replacement with the opposite groove.
Edit: But I prefer the idea of leaving it alone and adjusting the operator.
