The Ring Gear Installer Bridge Gauge measures the gap between the axle housing flange and the inner brake housing during differential setup. This measurement helps establish the correct shim thickness required to achieve the desired differential preload. The gauge provides a clear and repeatable reference across the mounting surfaces, allowing servicemen to capture accurate dimensional readings. By enabling proper gap measurement, it supports correct preload adjustment without trial and error. Accurate preload setup helps maintain smooth differential operation and reduces premature wear.Attributes:• Helps determine the correct shim thickness for differential preload setup.• Supports proper preload adjustment during axle service.• Enables reliable gap measurement without guesswork.Applications: The Ring Gear Installer Bridge Gauge is located across the axle housing flange and inner brake housing, where it measures the gap to define correct shim thickness, ensuring accurate differential preload.
