Maintenance knowledge and importance of bicycle pedals

1. The pedal shaft is also divided into steel shaft and titanium alloy shaft, the difference lies in strength and weight. In order to determine the degree of lubrication and usage, the pedal shaft will also pay special attention to water and dust, and O-rings and sealing nuts are usually used. With these two dust-proof and water-release measures, the bearing can maintain lubricity and smoothness in a relatively clean environment.

2. The interface between the pedal and the crank is connected by screwing and screwing. When installing, because the direction of force is different, the threads are also different, so the pedals will be distinguished from the left and right, and you need to pay attention to the logo on the pedals during installation. Today's pedals have made a big leap in quality. In order to maintain smoothness and smoothness, the use of bearings has become especially common.

3. Apply lubricating grease to the screw thread where the pedal is connected to the crank, and apply it evenly. Before applying grease, remove metal residue and dust from the threaded fasteners.

4. When installing the pedals, (wrench tightening as an example), we need to prepare a 15MM open-end wrench and a little lubricating oil. The wrench needs no explanation. Grease is for the convenience of disassembly in the future, and it needs to be added to the interface to protect the grease.

5. The pedal is an excuse for the thread. The common installation method is to try to tighten it with a 15mm wrench. There is also a way to tighten it with a wrench or a hexagonal wrench. In order to make some pedals more lightweight, the interface of the wrench has been canceled, and the hexagonal wrench can only be used to tighten them. No matter what tool is used to tighten them, it will not affect the quality of the pedal itself.

6. After applying the lubricating grease and before installing the pedals to the crank, remember to clean the dust and metal shavings in the threaded socket on the crank. First connect the threaded port of the pedal and the crank, and then tighten it with a wrench.

7. Rotate the installed pedals to check whether the pedal and crank connections are fully tightened.
