The axis of the spinning flywheel is inside the flywheel. The disadvantage of this structure is that the bearing is inside the flywheel and cannot fully support the axis. Moreover, when we step on, the power is transmitted to the wheel through the thread on the hub. of. Therefore, the spinning flywheel is stepped on tighter, which makes it very difficult to disassemble the spinning flywheel. The single-speed flywheel is also fixed by threads.
When disassembling the rotary fly, we must confirm whether the disassembly tool is correct and suitable. Generally speaking, we can use the number of internal teeth on the flywheel and the inner diameter to determine which tool to use.
Remove the wheel fixing nut or quick release lever, put on the rotating flywheel sleeve, reinstall the fixing nut or quick release lever, and then use a vise or adjustable wrench to fix the sleeve and turn the wheel. Once the flywheel starts to loosen, loosen the shaft nut or quick release lever and continue to unscrew the flywheel.
When reinstalling the flywheel, it is best to apply some anti-seizure anti-adhesive on the inside of the internal thread, so as to avoid the thread seizure and cannot be removed during the next maintenance or replacement.
