Symptom
The air compressor makes excessive noise during operation.Probable Cause
Loose drive gearInspect the fit of the drive gear on the air compressor crankshaft. The gear must be completely seated. The nut on the crankshaft or the bolt on the crankshaft must be tight.Loose drive components may cause damage to the air compressor crankshaft. Replace the air compressor if there is damage to the air compressor crankshaft.Tighten the nut for the air compressor drive gear or tighten the bolt for the air compressor drive gear to the proper torque. Refer to the Specifications section for the value for the torque of the nut or bolt.
Excessively worn drive gearsInspect the drive gears for excessive wear. Replace worn drive gears, if necessary.
Restrictions in the air compressor cylinder head or restrictions in the discharge lineInspect the discharge line for restrictions. Inspect the discharge port of the air compressor and inspect the discharge line for carbon buildup. Check for proper cooling of the air compressor if carbon buildup is found. Replace the discharge line, if necessary.
Worn bearings or damaged bearingsCheck for proper oil pressure at the oil inlet port. Refer to the Specifications section for the value for the minimum oil pressure.Check for high oil temperature. Refer to the Specifications section for the value for the maximum oil temperature.
Faulty air compressorReplace the air compressor or repair the air compressor if none of these causes exist.
