Pulleys

A pulley is a mechanism composed of a wheel on an axle or shaft. A rope, or cable usually runs over the wheel and inside the groove. Pulleys are normally used to change the direction of an applied force to make the work easier. It is one of the six simple machines.

How do you remove the crank shaft pulley on a 1995 Mitsubishi 3000 GT?

This question answer requires a service manual Crank shaft pulley removal is a complicated procedure and should only be done by people with experience as many parts need to be removed including the timing belt which if not done properly will cause damage to the engine. It would take the novice at least a day to do the job and requires some specialty tools. Go to Team3s web site for all of the information needed or Erik Gross s site. You may as well do the 60k and change all of the other parts involved while you are at it. The motor is an interference motor and putting the timing belt on improperly will cause the pistons to hit the valves so "Beware"

How do you de-tension the serpentine belt on a 1995 Chevy Cavalier?

If your car has a tensioner pulley it can be moved to release the tension on the belt for removal. Make note of the routing of the belt before removing it. This will make installing the replacement belt much easier. If you do not have a tensioner pulley one of your accessory motor/pumps (most likely your alternator) can be moved in order to release the tension on the belt.

Most tensioner pulleys have an hole the exact size of a ratchet drive on the tensioner arm. This allows you to put a standard ratchet (without any socket attached to it) into that hole and use the leverage of the ratchet to release the tension.

What does a smaller supercharger pulley do to a cars engine?

The smaller pulley spins the supercharger faster, thus creating greater boost and therefore more horsepower. Popular "sizes" are 15%, 17% and 19% reduction. The larger percentage reduction gives a greater boost. Some mechanics do not recommend the higher percentage pulleys.

How do you replace the water pump on a 1999 Daewoo Lanos?

While the below poster provided accurate information, there are some points a novice techinican or do-it-yourselfer should follow. You do NOT need to remove the intake manifold or fuel injectors/rail, or the alternator. You should be focused on the front end of the engine. The power steering pump, crank pulley, plastic covers, lower inner wheel splash guard will need to be removed to access the timing assembly. As well as the valve cover to access the cam shafts. If you are changing your water pump YOU MUST replace the timing belt, idler pulley, tensioner, and seals. This is cheap insurance to prevent failure, and a new engine or top engine rebuild if the belt was to fail. Keep in mind that contamination be it coolant or oil will shorten the life of the belt. Once you have access to the timing belt you must mark the positions of the pulleys with the #1 cylinder on TDC in it's compression stroke. The two cam pulleys have marks which should point at each other, and the lower crank gear should point towards the ground at a small recess on the black metal plate which houses the timing assembly. Before you remove the water pump MARK it's location on the engine block, marking the block and water pump. Remove it and mark the new pump in the same location you marked the old one. Upon reinstallation you can use these marks as a gauge to properly set the tension of the belt assembly. Adjustble timing rotations can be tricky for a novice or do-it-yourselfer and you can seriously damage your engine ig you over tighten or leave too loose.Be prepared to work! It is underneath your alternator facing the timing belt. It is the timing belt tensioner! Yes, your timing belt tensioner is the water pump! If after you remove the intake manifold, the injectors, the alternator and bracket it should be visible. Then you must remove the timing belt cover top and bottom. then there are Allen bolt holes in the metal protective plate for the water pump. I think there are four. You must loosen them. Drain the radiator fluid before beginning this whole process. Once the Allen bolts are loose you can use channel locks to loosen the water pump which will loosen the tension on the timing belt. once you've done that remove the belt. To totally remove the timing belt you must also remove the power steering pump and hoses and the pulley you'll find in your way as well. Once you remove the belt completely(put a new one in!!!! they recommend every 40,000 miles...if they break you will bend your valves which will turn into $1600 which I paid this is an interference engine!!!!! There are bolts that hold the water pump in on the water pump side. You also remove the water pump protector on the timing belt side. There is a seal that goes in with the pump on the timing belt side. Remove it, install the new water pump and replace that protection plate on the timing belt side. When you reverse this process once installed once the timing belt is on after ensuring the timing marks are in their proper position...DOHC marks and bottom is correct also. Then...you tension the timing belt, it is adjusted with a 41mm specialty wrench by turning the ecentric water pump (impossible to adjust without the wrench). Once you do this you back the tension off less than a 1/16 of a turn...in fact a hair backward. If you do not do this it will be too tight and make a loud whirring noise that will sound like the motor will explode. This will easily break the timing belt. Put it back together. I did this for the first time in about 8 hours. I hear this is a 4 hour job! hope it helps...

How do you build a homemade ground ultrasound machine?

"As is the case with X-rays this is no hobby for the amateur or (Ham). As far as I know it is illegal for an amateur to construct or operate an Ultrasound machine as you describe it and these are (completed models) restricted to licensed Medical Labs and practitioners. In other words it"s for the most part and for the soldering-iron types, against the law! I have never even seen an advertisement for a kit or schematic plans for such a device. Try something more palatable like weather computers(there were both analog and digital varieties) or maybe Night Vision devices."

The answer above is completely absurd, and does not even address the question. First of all, comparing ultrasound to x-rays, shows no knowledge of science. Ultrasound is merely sounds waves of higher frequency than can be detected by human hearing. Unlike x-rays which are electromagnetic energy, and are dangerous to human health if overly exposed. The answer also confuses ultrasound medical devices with what the question is asking, which is about ground penetrating ultrasound machine. Npw to address the question. Ultrasound, as mentioned, is high frequency sound. The problem here is that these waves do not penetrate very far into the ground and are unsuitable for detecting buried objects. Traditionally the mining industry uses explosives to generate the sound waves needed for deep ground penetration. Relatively small explosive charges are placed into holes, and microphones are placed in a matrix to record the shock waves bouncing back. Then the data is post-processed with powerful computers to create images of the sound waves resulting from the explosions. So, building a homemade version of this is probably impractical. There are portable ground penetrating radar machines, but that would be a whole different question.

The above answers do not take into consideration the research going on since the 1990's into ground penetrating ultrasound devices for landmine detection. The single drawback these devices have is the requirement of having a water saturated ground environment for the ultrasound to render clear and meaningful pictures. But, when operated in such an environment, they produce top quality high resolution photos of all kinds of materials - not just metals. Seeing something as tiny as a hairpin, at more than a meter - or being able to tell if a dime is heads or tails under a foot of soil.

How do you relax the tensioner pulley on a 2003 trailblazer?

There is a square opening on the front of the tensioner that fit a 3/8" ratchet. Place the ratchet in the opening and crank down toward the ground. You may need to slip a longer bar over the ratchet to get it down.

What jobs use combination pulleys?

How and what would you need to change your supercharger pulley on your 2000 Pontiac GTP to increase power?

You would need to remove the pulley and place a smaller pulley on to make the supercharger turn faster and pump more air. This can be done to a point but if you go too small without doing alot of other modifications to the intake and exhaust you will burn up your motor in no time. Check out the following website. http://www.gtpworld.com/index.html Read and learn from others mistakes. Hope this helps.

How do you set serpentine belt tension on a Chrysler?

What the constatnt loud noise is in my 2004 trailblazer it gets louder when you rev it its not the tens pulley or the idler pulley?

It could be the clutch fan that is going bad. I had the same issue & the expense of the part and manpower can be $400 to $700.

Can you use a regular pulley puller to take off your supercharger pulley Say a three jaw or kroes foot?

I just changed the sc pully on my 2000 GTP and I ordered a puller from eBay for about $100. It took a lot of torque to get it off. It took almost an hour to remove the old one and 10 mins to install the new. The puller makes contact with the entire pully so there's even pressure. Checkout www.3800performance.com and www.grandprixstore.com. They have pullers.

Tensioner pulley for a 93 mercury villager?

If you mean the Timing Belt Tensioner, it is behind the timing cover, just above the crank shaft to the left. Note: even though too many sources say that the 3.0 liter engine is an interference motor - its NOT, it was designed by Nissan (at the request of Ford/Mercury) be safe if a timing belt breaks - I can attest to this- I have replaced a couple of broken breaks - no valve or piston damage.
