The lubrication system has a pump (5) which draws lubricant from a reservoir and passes it through a single filter (9) to a dosing valve (13). This controls the lubricant flow to the application point at set intervals, and in between the lubrication periods vents the flow back to the sump. Pressure monitors (18,19) before and after the filter monitor the flow rate through the filter and a simple control circuit gives warning when the filter requires replacement. When the filter is replaced, between the lubrication periods, the pump is reversed to draw back fluid. The filter is bridged by a non return valve to allow drawback of lubricant.
