What do you need to know about torque specs?

It is important to note that most engine torque specs require 30w engine oil to get the correct stretch on the bolt. Some specialty fasteners require a specific lubricant. It is important to know which lube, if any, the bolt requires and to use it when tightening it.

What should the torque be on a torque wrench?

It is important to know which lube, if any, the bolt requires and to use it when tightening it. A torque wrench really only senses friction. For example, take a bolt with a torque specification of 50 lb ft.

Can a threaded fastener be used without torque specifications?

Without having the proper torque specifications, assembling an engine, or any threaded fastener as far as that goes, is just asking for failure. This is especially true on today’s lightweight engines that use mostly aluminum castings.

When to use a cutting torch fuel cylinder?

Cylinders should always be secured with the valve cap in place, when not in use. Cutting torch Fuel cylinders, such as acetylene, are filled to a much lower pressure, but fuel cylinders can also be dangerous if the valve assembly is damaged.

Is it dangerous to fill cutting torch with acetylene?

Cutting torch Fuel cylinders, such as acetylene, are filled to a much lower pressure, but fuel cylinders can also be dangerous if the valve assembly is damaged. Another risk to acetylene cylinders would be the creation of voids within the cylinder if it is indented or struck. Voids allow for the acetylene gas to move around more freely.

What does torque mean on a rocker arm?

The rotating lobes of the camshaft raise and lower one end of the rocker arm while the other end acts upon the poppet valve stem. Torque refers to the force required to rotate an object, in this case a nut or a bolt, around an axis or pivot.
