When removing a bicycle chain with a chain cutter, you need to put the chain in the chain cutter, align the ejector pin with the pin, adjust the tightening nut into the pin hole and push out the pin. The specific method is as follows:
1. First find the chain link and remove it with a bicycle chain breaker. Only by disconnecting from this place can it be reconnected.
2. Put the chain in the slot and put it in the correct position.
3. Adjust the tightening nut of the chain opener so that the nut is close to the chain to prevent the chain from shaking. Be sure to tighten or the pins will move.
4. Tighten the ferrule nut clockwise so that the front of the ferrule contacts the pin.
5. When pushing the chain, adjust the position of the lower chain so that the ejector pin is aligned with the pin so that it can enter the pin hole and push out the pin.
If the connected chain link seems very tight and astringent, we also have a way to deal with it – adjust the dead knot. Such inflexible links are called dead knots. Most dead knots are formed when connecting the chain – its two outer links are squeezed too tightly. To adjust the dead knot, hang the chain on the hanger near the screw hole and push the pin lightly. Since this hanger only supports one side of the chain, after it is pushed over, the pin moves a little in the chain piece on the pushed side, and the chain piece on the other side is pushed away by the pin, and the dead knot becomes loose. Some. It should be noted that it is enough to push it a little, and it is necessary to push the side with the longer outcrop of the pin shaft, so that the length of the pin shaft on both sides of the chain will be more even after adjustment. If the exposed part of the pin at one end is too short, use the method of connecting the chain to top the pin to make the exposed part long enough. At this point the link will be a little tighter again, so this adjustment process may need to be repeated a few times to get the desired result. There are still some dead knots. The chain is not very tight and astringent after it is just connected, but it becomes unable to move flexibly after using it for a period of time. Decide whether to adjust according to the situation; if the problem is serious, just adjust it directly. This kind of dead knot is often caused by the small gap when connecting. Another reason is that the chain is twisted and squeezed abnormally due to rough shifting.
Do not over-tighten the nut or use brute force, as the ejector pin of the chain opener can easily break!
