Do an experiment about air duster gun (1)

Air Dusters aren't just for cleaning things, they are also potential propellant. Here you will see how to launch small objects at reasonable velocity (i used erasers).

First lets go grab what we need. Of course you need the air duster gun with the little plastic straw. Nowdays this is available at Target and Wal-Mart or other places like that, along with electronics stores. Get whatever is cheapest, but it must have the plastc straw.

Now we need a click pen. The one pictured works best (and they are mostly free from car delerships) because it comes apart nicely.

We also need a lighter, or like I did the first time you can use a stove if you are really careful. A projectile can be found later, I use erasers from cheap pencils.

Do you hear ball joint separator?

We are ball joint separator manufacturer and we will provide some knowledge about ball joint separator.

The first signs of a failing ball joint include loud banging over bumps and/or sloppy steering as the joint separates out of its socket. A typical safety inspection should measure the amount of motion in your ball joint, and only allow a safe amount to pass. You can test ball joint play yourself on McPherson spring struts that do not put any load on the ball joint by lifting the car and manhandling the wheel. This design is rare, however, because most suspension springs apply constant pressure on the assembly.

If your car has a spring that puts load on either the upper or lower ball joint, you will need to remove that spring pressure by positioning your jack under the control arm and jacking it a few inches up to relieve the spring pressure on the ball joint. If the design allows, you can use a special ball joint support tool like the one made for the Saab 900 to hold everything in place. You can also relive tension with standard spring compressors, which is a common way of doing this.

FAQs about changing oil

We are oil filter wrench manufacturer, here I will answer some questions about changing oil.

Q. Is it necessary to use a stabilizer or additive with every oil change?

A. Nope. Today’s engine oils are formulated to fully protect the engine. They don’t need extra help.

Q. When should I change my oil?

A. You should change your oil and filter at, or before, the end of the oil-change intervals recommended by your vehicle’s manufacturer for your driving conditions. These intervals are based on mileage or time. By doing this, you can help keep your engine oil in good condition and provide the best protection for all your critical lubricated engine parts.

Q. How should I dispose of my old oil after an oil change?

A. Used oil pollutes the environment, and is hazardous and should never be poured down the drain or on the soil. You can drop off any used oil and oil filters at your closest National chain parts stores, City or municipal recycling centers or most oil change centers to be recycled properly.

How to choose the correct oil filter wrench?

An oil filter wrench is a handy tool for removing spin-on type oil filters. These filters are difficult to grip, especially when they are oily. Chain-type, strap-type, cup/socket-type, and claw-type oil-filter wrench are the most common oil filter wrenches in the market; we are here today to show you how to choose a correct size cup/socket -type oil filter wrench for your car/motorcycle.

A cup/socket-type oil filter wrench is usually metal steel or plastic cup that is shaped like a socket. The cup is placed on the end of the filter, which engages the knurling/ flutes. A socket or wrench is then used to loosen the filter.

There are many different aftermarket oil filters; it is sometimes confusing to choose the correct cup wrench that works properly. When shopping online, we'd suggest NOT to just search for your car/motorcycle model and year. If that's what you do, there's a very high chance that it might end up in the bin. A better way to do is to check the specifications of your oil filter wrench and search for the matching size.
