How to Pull And Install Harmonic Balancer .

When you want to replace your harmonic balancer, huh? There's good news and bad news. First, the good news: Installing a new balancer is a relatively easy task. And now the bad news: Getting the old one off the crankshaft is not. It could involve taking apart some of your car's body parts, like the front fender or bumper and probably even the radiator.

First, you'll probably need to go out and buy a tool you might not have -- a harmonic balancer puller. That's a specialized tool that's used to safely remove harmonic balancers without damaging your vehicle, and it also works on things like gear pulleys and steering wheels. Search around to find the right puller for your needs. They're usually around $25 or so.

Every engine is different, so if you want to change the harmonic balancer on your car, you'll need to search around various car forums and Web sites to see how it's done on your specific model. Generally, you'll want to remove the belt from the crankshaft pulley and then take the harmonic balancer mounting bolt off with a socket and ratchet. From there, you'll use the puller tool you just bought to take the balancer itself off the crankshaft .

As far as reinstalling the new harmonic balancer goes, it's pretty much the same steps in reverse. Just be sure to compare the old part and the new part to make sure the bolt hole locations are the same. And don't forget to pay close attention to the proper torque settings, too. If you can start your engine and the vibrations don't jar your tooth fillings loose, you've done the job correctly.

What does a harmonic balancer do?DNT Tools

A harmonic balancer sounds like a crucial part on a spaceship in some pulpy 1950s sci-fi story, or something you need so you can play music with hobos when you're ridin' the rails. However, it's actually an important part on your engine that helps your crankshaft last as long as possible.

As the cylinders in your engine fire, they move up and down, generating torque that's transferred into the crankshaft. As you may already know, the crankshaft is what converts the engine's power into rotational movement, eventually turning the wheels of the car.

But consider for a second the forces that are acting on the crankshaft -- they're tremendous. Each time a cylinder fires, a force acts upon the crankshaft, causing it to twist. But this force also causes vibrations in the crankshaft, and at certain frequencies, the shaft can resonate, which makes the vibrations even worse .

These vibrations from the engine can become too much for the crankshaft to bear, causing it to fail. And when that happens, your car won't run and you'll be facing some expensive repairs.

This is where the harmonic balancer comes in. The circular device, made of rubber and metal, is bolted at the front end of the crankshaft to help absorb vibrations. It's usually connected to the crank pulley, which drives accessories like the air conditioner. The rubber inside the pulley is what actually absorbs the vibrations and keeps them at a safe level. In essence, the device is designed to help prevent crankshaft failure. It's also sometimes called a "dampener."
However, the rubber material can deteriorate over time. So if your harmonic balancer is going bad, you could get rough engine vibrations, a cracked crankshaft, or even a serpentine belt that gets thrown off its track. Replacing one is excellent preventative maintenance, and that's exactly what we'll talk about next.

Anyone can done,6 DIY Automotive Repairs

No.1  Replace Fuel Filter

Cost: $10 to $30

Fuel filters are recommended to be replaced at regular intervals, which generally can range anywhere from 10,000 miles and up. A dirty filter left overtime will reduce your vehicle's reliability and efficiency, so it is important to try to keep up with this maintenance schedule as much as possible. The steps are as simple as disconnecting the battery, releasing the fuel line pressure (especially important for fuel injected vehicles), disconnect fuel line from filter, remove old filter, replace washers, install new filter, double check previous steps, then start vehicle and look for any leaks. Check with your local government to see if they have a fuel filter recycling program available, so you can properly dispose of your old filter.

No.2   Replace Brakes Pads

Cost:Typically under $25 for each brake pad

Changing brake pads is one of the most common and important maintenance servicing schedules you should adhere to. Worn brakes can get very costly when you allow them to become so thin, they damage other parts of the system. Your stopping ability will be compromised, which not only compromises the safety of your own vehicle, but the safety of others around you. What you will need in tools is a car jack, lug nut wrench, socket set, and a c-clamp. In case your wondering, there is a green option for brake pads, although it may not be available just yet. Check with your local government pages to see if they have a used brake pad recycling program available for disposal of your old.

No.3  Replace Spark Plugs

Cost:$15 and up

Another important maintenance job to keep your vehicle running mean and green is to change your spark plugs regularly. What happens over time is the metal on the electrodes can wear away and become coated with carbon deposits. This will effect the ability of the plug to ignite the fuel/air mixture and therefore reduce your overall vehicles efficiency. In general most experts will tell you that most specialty plugs are not worth their price as far as fulfilling their promised power increase and/or fuel savings. There are a number of them out there, such as the E3 and Halo plug. If in doubt, just use the same plugs that originally came with the vehicle. Installation is as simple as removing the ignition wires from the old spark plugs, removing plugs with a socket wrench, installing new plugs, then coating the inside of the ignition wire boots with a little dielectric grease for a good seal before snapping them onto the new plugs.

No.4   Windshield Repair

Cost: $5

Not that I want to put all those windshield replacement or repair shops out of business, but repairing a windshield with a do-it-yourself home kit can be a very easy and effective process. It is important to note that star chips with minimal to no cracks is the best candidate for this repair. To accomplish this project, all you need is a do-it-yourself windshield repair kit from an auto parts store or equivalent. Clean a 12 inch square area around the damage with a glass cleaner, then take a razor blade and smooth out the surface of all defects, making sure to pick out any loose pieces of glass found inside the chip. Most kits will have a plunger apparatus to inject the adhesive into the windshield, then all you have to do is allow the tool to do the rest of the work. One bit of advice is not to perform this project in the hot sun, as the adhesive will try too quickly to leave a clear finish.

No.5  Power Steering Flush

Cost: $5 and up

A mechanic can do this job for you for upwards of $30 to $100, but you can do this in the convenience of your own garage with a turkey baster. Yes, I said a turkey baster. The idea behind this is to work out as much of the old oil power steering fluid out of the system and replace it with new stuff. The process should replace 90 percent of the old fluid and you wont have to detach one hose or crawl around on the ground. What you do is take the turkey baster and siphon as much of the old fluid as you can from the fill canister located inside the engine compartment. Place the old fluid in a plastic container that can be safely transported to an oil recycling facility. Pour in the new fluid, start the vehicle, and work the steering wheel back and forth. Turn the ignition off, let the engine cool a bit, then do the entire process over again. Follow these steps three or four times, or until the fluid appears clear.

No.6   Transmission Fluid Replacement

Cost: $30 and up

This project often goes by another name at the mechanics shop, Transmission flush. A flush is a new method of taking clean fluid and flushing it through the automatic transmission, thereby effectively pushing out all the old contaminated oil from the system. However, many mechanics say that this is not always a good thing and can lead to transmission problems. The old way to replace transmission fluid is effective, fairly straight forward, and a heck of a lot less expensive. You'll need to get your vehicle in the air using a jack and a couple of jack stands, then climb under the vehicle and remove the pan bolts to the transmission. Use a large plastic container with a lid to dump the old fluid in, so you can easily transport it to your local oil recycling facility. Don't forget to replace the transmission fluid filter while you are inside the transmission and clean the inside of the transmission pan. It is also important not to over tighten the bolts when reinstalling the pan or it will cause leaks.
