Kohler ED0067451010-S Oil Pressure Switch

The Kohler ED0067451010-S is a normally closed oil pressure switch designed to monitor lubrication system pressure in Kohler KDI series diesel engines. It activates at a falling pressure threshold of 0.5 bar (7.25 PSI), providing a ground signal to the engine control unit or warning lamp circuit. The switch features a single spade terminal connector and a threaded mounting body for direct installation into the engine block oil gallery. This part supersedes previous revisions ED0067451000-S, ED0067450990-S, and ED0067450950-S. It is a critical safety component for preventing engine damage due to oil pressure loss in industrial and construction equipment applications.
