Causes of Bending of Motorcycle Crankshaft and Crankshaft Pin?

There are many reasons for the bending of motorcycle crankshafts and crankpins, because we do not pay attention to maintenance during use or we fail to deal with minor problems in time, which will cause the crankpins to bend. We analyze the reasons for the bending of motorcycle crankpins as follows:
(1) The main bearing clearance is too large, and the engine works under impact conditions such as deflagration or overload, causing the crankshaft to vibrate excessively.
(2) A few cylinders do not work or work unevenly.
(3) The tightness of each main bearing cover is inconsistent, causing uneven stress on the crankshaft.
(4) Coaxiality deviation of main bearing seat hole of cylinder block.
(5) Improper operation and excessive start when towing the trailer.
(6) the crankshaft storage is unreasonable, long time horizontal without support.
Through the above analysis, it is not difficult to see that the reason for the bending of the crankshaft pin is that our use is unreasonable, so we must know how to use every component of the vehicle in the process of using the vehicle.

Repair of Cracks in Crampins
Chongqing Xiexiang Machinery Manufacturing Co., Ltd. is a company focusing on the production and sales of crankshaft pin. It is a crankshaft pin factory in Chongqing, a crankshaft pin manufacturer in Chongqing and a crankshaft pin company in Chongqing. We stand in a very professional point of view to analyze how to repair the crack of the crank pin. If the crack occurs in the non-stressed position or the crack does not extend, it can be repaired. Crank pin cracks in the pin shank arm and pin neck and other stress parts, should be replaced with new parts. Therefore, our crankshaft pin is required to have sufficient strength and rigidity, and the surface of the journal needs to be wear-resistant, work evenly, and have good balance.

Repair of crank pin of motorcycle
As a motorcycle crankshaft industry research for more than ten years of small series, has long known that the production of the crankshaft is a high technical accuracy of the work, then how to repair the crankpin? First of all, we analyze the crankshaft pin fineness, crankshaft journal roundness and cylindricity error of more than 0.01~0.0125mm, should be in a special crankshaft pin grinding machine for grinding. Crankshaft pin radial runout, generally not more than 0.04~0.06mm. If it exceeds 0.10mm, it needs to be corrected.
