What are the symptoms of camshaft noise in the EA888 engine?
1 Answers
The symptom of camshaft noise in the EA888 engine is the sound produced between the camshaft bearings and the shaft during engine operation. It is a rhythmic, dull metallic knocking sound, which is more noticeable when idling or at slightly higher idle speeds, especially when listening near each camshaft bearing. The camshaft is a component in a piston engine that rotates at high speeds and must withstand significant torque, thus requiring high strength and support. It is typically made of high-quality alloy steel or alloy steel. The following are the causes of camshaft noise: 1. Excessive clearance between the camshaft and its bushings. 2. Rotation of the camshaft bushings. 3. Bending or deformation of the camshaft. 4. Excessive axial clearance of the camshaft. 5. Burning or detachment of the camshaft bushing alloy.
