Главное кольцо дизельного двигателя Caterpillar 1478860

The Diesel Engine Master Ring is a reference tool used during measurement setup procedures to establish an exact internal diameter for calibration purposes. It allows a dial bore gauge to be set to a known dimension before actual bore measurements are taken. It offers a stable and fixed-size reference, the ring ensures that the gauge readings reflect true dimensional values. The component plays a direct role in eliminating measurement deviation during engine inspection tasks.Attributes:• It calibrated the dial bore gauge to 280.025 millimeters.• Ensures calibration accuracy before bore inspection.• Controls measurement reference during calibration procedures.Applications: The Diesel Engine Master Ring is used during measurement setup procedures to calibrate a dial bore gauge to a defined internal diameter before checking engine cylinder bores.
