Mechanical torque wrenches do not require maintenance

Mechanical torque wrenches do not require maintenance This is the basic structure of a torque wrench. See the diagram for the principle. What I want to say is, I saw on the Internet, some merchants said: You can repair it yourself The reason is simple, you must have a professional machine to destroy it. Even if you destroy it, how can the internal parts be obtained? If you really want to repair it, you can only send it to the original manufacturer or agent, they may be able to get the parts In fact, the time cost of repairing a torque wrench is higher than manufacturing one. The original factory will not repair it for you, at most it will replace it for you Moreover, after three to five years of use, all internal parts that will wear out should be replaced. How is it possible to complete the repair with only one part replacement?
For example, Facom offers three years of free replacement in France. Stahlwille does not allow any non-agents to perform repairs I have seen a lot of photos taken apart, the photos are meaningless. I really want to ask those crooks to take a video to take it apart, then update the parts and put them back. Even if the original factory is willing to provide parts, you must have a laser-positioned drilling and punching machine, and a special fixture. To disassemble the wrench without damage and replace parts Does the torque wrench need maintenance? I don't think it is necessary. Professional users will be damaged after three to five years. If you are not using it professionally, just drop a little engine oil to wash off the iron powder and recalibrate it.

二十年前的东日，日本制造还在用，测试下来比欧洲的精度高。
