The crankshaft is stored in the crankcase, so one of the most important parts of a scooter. Here it is very important that the crankcase is manufactured and machined on high-quality CNC machines. The holes must be exactly opposite each other. The tolerances must be very tight and in the 1 / 100mm range. When assembling the crankshaft, make sure that the crankcase is not damaged during installation. The best thing to do is to use physics to help, heat the crankshaft housing shells, then you can install the crankshaft with the bearings without a pressing tool. When it cools, the storage is bombproof. Expertise is required. Overheating during heating must not occur.
