1 The gap between the piston rod and cylinder wall of the diesel engine is too large, or the cylinder liner is too tight, or the gap between the tappet and the pilot hole of the diesel engine is too large.
2 Crankshaft FRACTURE, CYLINDER LINER sleeve LOOSE, OR because of diesel engine CAMshaft timing gear split or its fixed nut loose caused by.
3 Crankshaft bearing loose loose, piston pin melting or specifications do not meet the rotation, engine crankshaft bearing loose loose or piston pin melting, cylinder liner fracture, wood grasping engine crankshaft fracture.
4 in the engine piston knock cylinder, or because the crankshaft bearing is loose, it is also possible that the engine piston leakage, etc.
5 cylinder sleeve sleeve loose loose, piston rod skirt cone over large, cylinder sleeve out, crankshaft bearing cover fixed anchor bolt loose or even crankshaft piston pin aluminum alloy melting net these.
6 The engine crankshaft bearing is loose.
7 wood grasping machine piston rod and cylinder wall between the gap is very large, or diesel engine.
Abnormal crankshaft sound, diesel engine vibration: engine crankshaft radial clearance is too large to cause abnormal sound, again select bearings to remove the abnormal sound.
Main bearing abnormal sound, diesel engine vibration: the spindle bearing neck and bearing cooperate with each other loose, the main bearing is not well lubricated and burned, the engine crankshaft bending or radial clearance is large.
Engine idle abnormal sound, low and medium speed clank sound: poor lubrication or poor bearing coordination, poor bearing quality or too loose installation clearance, too urgent to make the bearing plate deformation and lead to aluminum alloy fall off, crankshaft motor shaft loss of circle, and bearing loosening.
Abnormal sound of timing gear of excavator: timing gear damage or poor installation, the gear gap is too large or too small, the engine crankshaft and engine camshaft axis is not parallel surface, engine camshaft timing gear loose or poor wetting, engine camshaft timing gear transmission gear fracture or transmission gear axial splitting.
Abnormal noise of the cylinder foot of the diesel engine of wood grasping machine: the parts of the cylinder transmission mechanism are damaged or poorly adjusted, the cylinder gap is too large, and the cylinder transmission mechanism is lack of wetting.
Diesel engine squeaks, wood grabber hydraulic taming column abnormal sound: engine oil oil level is too high or too low, hydraulic taming column lack of grease, hydraulic taming column is ineffective.
