China Diesel Engine Parts The crankshaft is the most important part of the engine. It takes the force from the connecting rod and converts it into a torque that passes through the crankshaft and drives the other accessories on the engine. The crankshaft is subjected to the combined action of the centrifugal force of rotating mass, the gas inertia force of periodic change and the reciprocating inertia force, so that the crankshaft bears the action of bending torsional load. Therefore, the crankshaft is required to have enough strength and stiffness, and the surface of the journal should be wear-resistant, uniform and balanced. The crankshaft and crankshaft bush are Mainly used in engines of YTO. YTO Tractor engine LR4M5R, LR4V5R, LR4A3LR, LR4M3LR, LR6M3LR,YM6K7LR. Harvesters engine LR4A3LR, LR4M3LR,LR6M3LR,YM6K7LR,YM6S4LR. Construction machinery engine YT4A2ZU,YT4A4ZU,LR4B3ZU,LR4A4LR,LR4M3LR,LR6S4LR,crankshaft bush.China Diesel Engine Parts website:
