We all know that the motorcycle crankshaft is the core component of the motorcycle engine, so how do we judge the quality of the motorcycle crankshaft? The method is as follows:
First look at the connecting rod, hold the connecting rod and shake it up and down, and feel that there is a gap, even if it is small, and the left and right shaking connecting rod swings greatly, it means that the big end bearing of the crankshaft connecting rod is damaged, then look at the crankshaft at both ends, and put the bearing It should be a little tight. It needs tools to be installed or hot installed. It is easy to insert it. This position should be tightly, this is wrong. One of the problems is crankshaft channeling, and the other is that the crankshaft will bounce during operation and cause vibration. If there is a dial indicator, you can measure the circular runout of the crank, check the crankshaft pin hole, insert the piston pin, and do not Loose, push the piston pin left and right without applying oil, it should be a little tight, it is very smooth after applying the oil, and finally the bending of the connecting rod requires professional testing to confirm.
The above way to judge the quality of the motorcycle crankshaft can be useful for motorcycle enthusiasts!
