When working with cars, you deal with a lot of specialized tools. Something like a torque measurement machine will be used constantly in your shop, but you likely won’t use it in other places. If you need to do torque measurement and your machine breaks, you won’t be able to do that or do continuous torque monitoring. You’ll need to either repair or replace your tool. While replacing it can be convenient, it can also be very expensive. If you only need a partial repair, like a clamp on a torque cell, then replacing it causes you to pay extra money. If you can repair your tools, you’ll be able to save money and keep working with tools you feel comfortable with. Whether you need to know what is static torque, or if you’re trying to repair something in your shop, repairing your tools will give you a better understanding of how they work. This will make you a better repairman as well as save you money. So, next time you have to choose between repairs or replacement, consider repairs first.
