  Chapter 6: Lubrication & Cooling Systems › Pressure System › Magnetic Chip Detectors

  Magnetic Chip Detectors Magnetic chip detectors are used in the oil system to detect and catch ferrous (magnetic) particles present in the oil. [Figure 6-44] Scavenge oil generally flows past chip detectors so any magnetic particles are attracted ... stick to the chip detector. Chip detectors are placed in several locations but generally are in the scavenge lines for each scavenge pump, oil tank, and in the oil sumps. Some engines have several detectors to one detector. During maintenance…

  Chapter 8: Engine Removal & Replacement › Reasons for Removal of Reciprocating Engines › Metal Particles in the Oil

  Metal Particles in the Oil Metal particles in the engine oil screens or the magnetic chip detectors are generally an indication of partial internal failure of the engine. Carbon tends to break loose from the interior of the engine ... necessary to consider these possibilities when foreign particles are found on the engine oil screens or magnetic chip detectors. Before removing an engine for suspected internal failure, as indicated by foreign material on the oil screens or oil sump plugs…
