Ferguson hydraulic pump

On wednesday a productive day was spent removing and repairing the fergie’s hydraulic pump.

The problem turned out to be that the rod which operated the control valve had bent and was therefore jammed.

In addition to this it was discovered that the oscillator rod had snapped at the point where it joins the square oscillator key. This is a system fitted to the revised pump as a way of preventing the control valve from sticking by forcing it to rock back and forth as the pump turns.

As a replacement part could not be sourced easily the decision was taken to leave out the oscillator assembly.
