Checking the engine oil pressure (Ducati ST2)

0

To check the engine oil pressure, remove the pressure switch and then fit a pressure gauge complete with hose (A) to the threaded hole (M10x1) in the RH casing. When the engine is cold the oil will be thicker and the pressure reading obtained will therefore be higher.



The maximum pressure must not exceed 6 bar.

Oil pressures:

Cold engine:

• at 1100-1300 rpm: at least 2.5 bar.
• at 3500-4000 rpm: between 4 and 6 bar.

Hot engine:

• at 1100-1300 rpm: at least 1.1 bar.
• at 3500-4000 rpm: between 4 and 6 bar.

A pressure which is too high indicates that the limit valve is jamming. A pressure which is too low indicates that the limit valve is jammed in the open position, that the spring is too weak, or that the oil pump is faulty. Other causes of faulty pressure readings include: badly worn seals and gaskets; badly worn engine.
