Avoid stripping threads

You would be amazed at how easy it is to strip threads on your scoot using tools such as a ratchet set or monkey wrench. In fact, I have stripped the threads that my valve adjust cover screws into with a monkey wrench (see previous post titled "Oil Change") and I have stripped the studs on my rear wheel hub with a ratchet set. More on that later.

The best way to avoid this is to purchase a torque wrench for $12 (sale price from your local Harbor Freight Tools) and set the correct "foot pounds" prior to tightening everything up. This will avoid any errors at a cheap price. Do NOT use the torque wrench to remove nuts or screws as it could damage the internals of the wrench.

The "free" way to avoid stripping threads is to tighten with your hands all the way and then just snug things up a hair with wrench. Use the Bajaj hub/wheel wrench ONLY when removing and especially when installing the lug nuts. Don't kick the wrench like you do on a car. Do it all by hand. This will help you avoid stripping anything. If you want to be extra safe use nylock nuts -- but make sure to replace them every time you change the tire.
