Harmonic balancers are a common wear item on many engines. They are responsible for keeping the engine’s crankshaft in balance, and over time they can wear out and need to be replaced. However, in some cases it may be possible to have the harmonic balancer repaired instead of replaced. This will typically be less expensive than replacing the entire unit, but it may not be possible in all cases. If the harmonic balancer is severely damaged, it is likely that it will need to be replaced. However, if the damage is minor, a repair may be
Most harmonic balancers cannot be welded without causing damage to the internal workings of the balancer. It is possible to weld a harmonic balancer, but it is not recommended.
You can run an engine without a harmonic balancer, but it will not run for long. The harmonic balancer is responsible for dampening vibrations from the engine, and without it, the engine will eventually shake itself apart.
Most harmonic balancers have rubber in them, but not all of them. There are some harmonic balancers that are made with other materials, such as steel or aluminum.

purchased this to swap with a Silverado 6.0. If your LS motor has been used for any distance, these can separate and produce noise and vibration. Like any AC DELCO item, the quality is excellent. very content. Oh, and make sure you obtain a new bolt for it and torque it in accordance with your manufacturer handbook. If not, the balance may lose stability.

Several months ago, I required this for a Gen 3 LS motor, and it had no trouble removing the old balancer. I didn't bother to submit any further favorable reviews because there were already so many here. The lower steering stem race from a vintage Japanese motorcycle was difficult for me to remove tonight. You cannot use a drift to tap the race out from above because it is recessed and located at the bottom of a tube. The handbook mentioned a unique tool that is no longer produced, and a recent one that might have worked cost around $40. I started scanning my shop when I noticed this puller.In a video I saw, the driver maintained strain on the arms while someone else worked on the race using a gear puller flipped inside the steering head. Since I was alone, I flipped this puller's arms up in order to invert it. Two of the three arms could fit through the opening, but not all three. This is a terrific tool that has more than paid for itself. I placed a 1/2" drive long extension between the arms to maintain strain on them and then used a bar from above to hammer the race out. Within 2 minutes the race popped out.

My 2004 Explorer's 4.0L V6 Flex Fuel harmonic balancer split into two pieces. This was the appropriate substitution. From your Ford dealer, get a new center bolt for it (it cost me $8.00). It's difficult to find a universal puller/installer kit that works effectively. I purchased a 5.5" long 3/8" carriage bolt to insert into the center hole for the puller to push against in order to remove the old one. I started by tightening the replacement pulley with the old bolt before switching to the dealer's new bolt to complete the installation. Although it's probably not the ideal approach, I had trouble finding any other tools that would work for me.It was $20 less expensive here than at my local parts store and Dorman makes high-quality products.

The plate is thin and appears to be made only of mild steel, to start. It ought to be a little bit more resilient. Although I could see that it was beginning to bend somewhat, the balancer was pulled smoothly.Fortunately, I was able to attach it to the balancer using the original pulley bolts. There are a number of bolts available, but there were only two that were the proper length and diameter for my engine (a Ford small block), which called for three. Although I was able to make it work, it would have been wonderful to have a third bolt because the factory pulley bolts weren't long enough.Overall, it's OK, not spectacular, but it works. Given that I won't use it more than a few times, it was worth the money I paid.

You need Adobe Flash Player to view this video.Download Flash Player.In a nutshell, I enjoy finding bargains and making them work.This is an excellent tool, but it needs a few tweaks.Since February 2019, I've used it on three different cars, and it's been wonderful. There's no need to pay $100 on the more expensive one.

excellent toolused to replace the timing belt on a 2004 Sienna 3.3L.In order to access the cam seals, I needed it to remove the cam sprockets.Keep the timing belt AND tensioner still on the engine, align all timing marks before removing the tensioner, and do not pop the bolts off the cam sprockets since they may shift a few degrees off the timing marks and cause the cams to "jump" and perhaps damage valves. then, while the timing belt is still on or hasn't been removed from the engine, use a socket and wrench (with a pipe) in one hand and this tool in the other to loosen bolts on cam sprockets.When the cam sprocket bolts are loosened, you'll see that the sprockets have shifted away from the timing mark; however, since the timing belt is still attached to the engine, you may quickly correct the cams' timing markings by moving the crank pulley bolt.Overall, changing the timing belt is not as difficult as it first appears. You may have some cuts and scrapes on your hands and fingers, as well as some busted knuckles, but this can be accomplished with simple tools. Rubber gloves are very necessary; otherwise, washing hands and trying to get oil and debris off of hands and nails is a waste of time.Make sure you have and use just 6 point sockets because 12 point sockets will strip the head on the bolts. For Sienna timing belt job, you will be utilizing largely 10, 12 and 14 mm sockets with 3/8 ratchet and lot of varied length extensions.I only needed to raise an engine using a spare floor jack and a 2x4 block; I didn't need to remove studs for the water pump.Anyway, this pulley holder is excellently manufactured, makes the process much easier, and is worth the money! Buy it !

The tool operates flawlessly. Nothing to guess at, nothing to bend, simply plain strong and light. I wholeheartedly endorse this tool for both professionals and beginners. It doesn't even appear used or worn after three sets of heads (317, 706, and 799) that I did. It will undoubtedly persist for some time. Only that particular tool drew my attention. This item is quite thick and cannot be bent in the same way as other valve spring tools with a similar construction. If I could, I'd give 10 stars. You won't be let down.
A harmonic balancer is a device connected to the end of an engine's crankshaft that is designed to reduce vibration. It does this by offsetting the weight of the crankshaft at the point where it is connected to the engine block. Many people believe that a harmonic balancer can increase horsepower, but there is no evidence to support this claim. In fact, a well-designed harmonic balancer will actually have a very small impact on engine performance.
Harmonic balancers are often confused with timing belts or chains because they are located in the same area of the engine. However, their functions are entirely different. Harmonic balancers absorb engine vibration, which timing belts and chains do not.
Harmonic balancers go bad when they become worn out from age or from being overloaded. The symptoms of a bad harmonic balancer include vibration, noise, and engine misfires. If the harmonic balancer is not replaced, it can cause engine damage.
There are a few factors to consider when choosing a harmonic balancer. The first is the size of the engine. The harmonic balancer needs to be the correct size for the engine, or it will not work properly. The second factor to consider is the type of engine. Some engines are more susceptible to harmonic imbalance than others. If the engine is susceptible to harmonic imbalance, a heavier duty harmonic balancer may be needed. The third factor to consider is the application. Some applications, such as high performance or off-road, may require a different harmonic balancer than a stock application.
If your vehicle has begun to vibrate excessively while idling or while driving at low speeds, it may be time to replace your harmonic balancer. A broken or damaged harmonic balancer can cause engine misfires, decreased fuel economy, and other serious issues. To check if your harmonic balancer needs to be replaced, look for signs of wear and tear, such as cracks or missing chunks of rubber. If the damage is severe, it will be obvious just by looking at it. If you're unsure, you can always take it to a mechanic to have it checked out.
If you need to remove a harmonic balancer without a puller, you can use a few different methods. One method is to use a pry bar to remove the harmonic balancer. Another method is to use a screwdriver to remove the harmonic balancer.
