Review CAT Nos. Oem Start/pilot Pressure Switch Caterpillar

The Caterpillar Part No. 117-3187, also known as the Start/Pilot Pressure Switch, is an essential component in the electrical system of various Cat engines. This switch plays a crucial role in supplying the necessary electrical current to start the engine and maintaining the pilot pressure for smooth engine operation.

This pressure switch is designed with precision and durability in mind. It features a robust construction with high-quality materials that can withstand the rigors of heavy-duty applications. The switch housing is made from heavy-duty cast aluminum, providing excellent heat dissipation and resistance to corrosion.

The 117-3187 switch consists of a diaphragm assembly that is sensitive to engine oil pressure. When the engine oil pressure drops below the specified level, the diaphragm assembly moves, and the switch opens. This opening allows the electrical circuit to be closed, supplying power to the starting motor to crank the engine. Once the engine oil pressure reaches the required level, the diaphragm assembly moves back, and the switch closes, disconnecting the starting circuit.

This Caterpillar pressure switch also serves as a pilot pressure switch. It maintains a constant electrical circuit for engine systems that require a steady pilot pressure, such as the fuel system and cooling fan circuit. When the engine oil pressure drops below the pilot pressure setting, the switch opens, disconnecting the pilot circuit. Once the engine oil pressure recovers, the switch closes, reconnecting the pilot circuit.

The 117-3187 switch is easy to install and replace. It comes with clear markings on the switch body for easy identification of the various terminals. The switch terminals are securely fastened to the switch body, ensuring a reliable electrical connection.

In summary, the Caterpillar Part No. 117-3187 Start/Pilot Pressure Switch is an essential component in the electrical system of various Cat engines. Its robust construction, sensitivity to engine oil pressure, and ability to maintain pilot pressure make it an indispensable part of engine operation. If you are looking for a reliable and durable pressure switch for your Cat engine, look no further than the 117-3187.
