Affected: AND 3800 ENGINES
The crankshaft sensor adjusting tool (J37089) should be used for accurate sensor positioning and determining interrupter vane concentricity. This tool can be used to adjust all crankshaft sensors with the exception of the Delco single slot design illustrated below, and can be used to check the concentricity of the interrupter vanes on ALL C3I harmonic balancers. Use of this tool will ensure proper clearance between the interrupter vanes and sensors to prevent replacement sensors from becoming damaged. Use the Kent-Moore feeler gage style crankshaft sensor adjusting tool (J36179) on Delco single slot design sensors.
