The Master Depth Gauge allows accurate checking of depth relationships associated with spacer plate engines and liner seat inserts to confirm proper seating conditions during inspection activities. The gauge helps identify uneven seating or depth variation that can affect overall engine performance if left unchecked. By providing clear depth reference readings, the tool supports consistent assembly outcomes and reduces the chance of rework caused by incorrect seating.Attributes:• Supports repeatable inspection results for engine components.• Helps avoid operational issues caused by uneven seating.• Enables clear verification of spacer plate depth conditions.Applications: The Master Depth Gauge is used during engine inspection and service activities where spacer plate engines are evaluated and checks the liner seat insert depth to confirm proper seating conditions.
