Perkins Oil Pressure Switch OEM: T431758

The Perkins Oil Pressure Switch (OEM T431758) is a replacement engine component designed to monitor lubricating oil pressure within compatible Perkins diesel engines. The switch provides an electrical signal to the machine's monitoring or warning system, allowing the operator to be alerted if oil pressure falls outside the required operating range. Perkins parts information identifies T431758 as an oil pressure sensor/switch and specifies a two-terminal configuration.

Fitted directly into the engine lubrication system, the switch operates in response to oil pressure and forms an important part of the engine protection and monitoring arrangement. A faulty or damaged switch can result in incorrect oil-pressure warnings or loss of pressure monitoring, making replacement important where the original component is no longer operating correctly.

FUNCTION AND OPERATION

• Monitors lubricating oil pressure within the engine.
• Provides an electrical signal to the engine or machine monitoring system.
• Supports the operation of oil-pressure warning circuitry.
• Helps provide early indication of inadequate engine oil pressure.
• Replaces a faulty, damaged or unreliable original oil pressure switch.

IMPORTANT INFORMATION

Oil pressure monitoring is an important engine protection function. If the oil pressure warning system is behaving incorrectly, the switch, wiring and actual engine oil pressure should be checked before replacing the component.

Always check the OEM number and engine serial number or machine model before ordering to ensure the correct oil pressure switch is selected.
