Air Gap Measuring Gauge Caterpillar 3989615

An Air Gap Measuring Gauge measures the air gap between the crankshaft position sensor and the crankshaft. This measurement is for ensuring accurate readings from the crankshaft position sensor, which directly affects the engine's timing and overall performance. The gauge is engineered to provide accurate and consistent measurements, aiding in the proper alignment and positioning of the sensor. By maintaining the correct air gap, the gauge helps prevent misfires, poor engine performance, and other issues related to incorrect sensor positioning.Attributes:• Provides a quick and efficient method for checking crankshaft position sensors.• Provides calibration tools for accurate adjustments.Applications: An Air Gap Measuring Gauge is used near the engine assembly, at the location of the crankshaft position sensor, to measure the gap between the sensor and the crankshaft, ensuring proper sensor placement and accurate engine performance.
