I am prepping a 2002 Acura TL 3.2 engine and doing the timing belt and water pump, seals, etc. while it is out of the car and accessible. For the past week I've been regularly going to the garage, spraying penetrating oil on the bolt, and then trying to loosen it with my electric 1/2" Milwaukee impact gun and a 19mm impact socket. This isn't my first time removing a Honda crank bolt and it has always been a nightmare, I've done everything from absurd cheater bar lengths to the starter trick. Like everyone else I saw this on here and decided if it saved me time and effort, it was worth the $25. Today the tool finally arrived so I figured I'd give it a try, and heck, why not record it as well. Not even 10 seconds and the bolt was loose. Insane. Absolutely insane. I feel cheated by the hours and hours I've spent struggling with these bolts in the past. I can't believe it. If you're doing a timing belt job on a Honda or Acura, or a vehicle that could use this tool, buy it. The reviews are absolutely right. I posted a video as well showing it in action, I hope it helps.

Buy NOW. 2011 Honda Odyssey 105k, crank bolt would not budge. Had the holding tool and tried to break lose with pull bars, which broke a 1/2 inch extension. This was the first bolt my cobalt 1/2 electric impact would not break free. Borrowed 3 different air 1/2 impact tools which also wouldn't do the job with a normal 19mm impact socket. Went back with different extension and cheater pipe on pull bar still no go. Ordered this and while waiting on it kept spraying the washer with PB blaster (was so tight not sure this was able to diffuse in) . As soon as this came in I went back with the cobalt 1/2 electric impact, took about 45 seconds of hammering before I heard the sweet sound of wizzz :) This tool would have saved me at least 4 hours.

WOW!!! This actually worked on a 2001 Acura with 180,000 miles! While working on another vehicle that required the usual 5' breaker bar to remove the crank shaft bolt I saw this item. Hey, for $27 its worth trying, so I bought it for my next job (2001 Acura). After applying penetrating oil 5 times over a 3 hour period I gave it a try. After just a few pumps of the trigger I applied continuous pressure for about 10 seconds and it came loose. I was truly shocked. I intended to let the oil penetrate for 24 hours, but figured I'd give it a shot before closing down and the bolt came out with only the 3 hours soak time. My pneumatic gun is nothing special or super powerful.....its 20 years old and don't remember where I got it. My air compressor is only a 5 gallon tank and didn't even kick on removing this. I was a skeptic but am now a believer. Again wow! This worked perfectly again on my Honda CRV. Again, I sprayed the bolt with penetrating oil before hand, and again in seconds the crankshaft bolt came out. I wish there was a 6th star to rate this product. It works better an advertised.

OMG. This thing saved my timing belt change experience on my Acura 2003 MDX. I couldn't get the crank pulley bolt off with a 24" breaker bar and the crank holder (see photo of how I had my foot on stuff), but this thing with the

This socket does everything it said it could. The extra mass makes harmonic balancer bolts run and hide. Made in Taiwan but I have no fear of this behemoth ever breaking. With my IR impact it makes short work of even the most stubborn bolts.

Writing this to help other Honda owners. I am doing a timing belt on my 2010 Accord V6, and based on the videos and forum info, this tool seemed like the way to go. FYI, I already own the harmonic pulley holding tool (hex shaped) and used it once a few years back on another Honda...it was a nightmare, and seriously sounded like a 45 cal handgun went off when the bolt finally came loose. Once I got this tool, I figured that I better make sure it works BEFORE I actually start the timing belt job. Getting to the bolt only requires removing the front right wheel and a couple of plastic fasteners and bending the plastic down out of the way. I figured I should make sure I can get the bolt loose, and then I can immediately re-tighten and put the wheel back on until I'm really ready to do the whole timing belt job and water pump ect. First I used my very old Ingersoll Rand 231 (freshly rebuilt) set on 110 psi. Did not work. So I went to Lowes and got a new Kobalt Impact (700 ft-lbs) for about $100. It didn't work. So I watched all of the videos online showing guys zipping that bolt off with their 1/2" impacts and wondered what I was doing wrong. So I drained the air out of my tank, removed a gauge that was directly on the tank, and put my hose there (bypassing the regulator altogether, AS WELL AS ELIMINATING ANY RESTRICTION FROM THE QUICK DISCONNECT FITTINGS). Same thing at the tool end of the hose: removed the quick disconnect fittings and plumbed hose straight to the IR 231. Still did not work. So finally, I put the new Kobalt directly on the hose (now with no restrictions) and guess what. Success. So if you buy this tool, make sure you: number 1: have an excellent impact gun, number 2: use high flow fittings or no fittings (directly plumbed to tank and tool) to eliminate restrictions, number 3: at least 3/8 ID hose. Good flow and a great gun are necessary for this tool to work. But it does indeed work, and is soooo worth the trouble. Hope this helps somebody.

Situation: 1998 Civic, 1.6L needed a new crank sensor, but the crank pulley needed to come off. The bolt was very tight. Task: The bolt needed to be removed, but was stubborn. Action: I have impact sockets and a reasonably good old Craftsman impact wrench, model 875.199870. That wasn't enough. We must have tried it ten or fifteen times. Nothing happened. Then we tried a long pipe on a breaker bar with the proper 50mm tool to hold the pulley steady. No action other than really twisting the extensions. Like a huge spring, but it didn't break loose. I was afraid I'd break the breaker bar, extensions, or something. Then I saw an Eric the Car Guy video recommending 125psi on the air pressure. And tried it another ten times with the impact. Still no luck. Then ordered this part and an Ingersoll impact. This part arrived first and I was impatient so I thought I'd try it without waiting for the Ingersoll to arrive. Result: This tool plus the 125 psi line pressure, plus my old Craftsman impact wrench broke it loose on the second try. I think what's happening is that its metal is so thick and strong that a lot more of the hammering of the impact goes directly to the bolt rather than deflecting and stretching. Amazing. Buy this tool before you need it. Because someday you'll need it I ordered it yesterday afternoon and it arrived this morning. Very pleased. If you have a Honda and do your own work buy this before you need it.

I pounded on a Civic crankshaft bolt for about a minute using a standard 19mm socket. No luck. Switched to this, and it was off in a few seconds. Putting the bolt back on, I was able to get another quarter turn using this versus a standard socket. (I don't recommend doing this, however, as the factory service manual advises against it. Spec for my car is something like 180 lb-ft plus an extra 90 degrees). Some people have asked whether this fits through the harmonic-balancer holding tool. It does not, but there is really no need to use that tool when using this socket with an impact wrench. The short bursts of torque from the impact wrench do not turn the crankshaft. I have, however, noticed that Ingersoll Rand makes a socket similar to this (possibly listed in "similar products" below) with a smarter, less brute-force design. It is a thinner socket with a concentric ring in which the mass is concentrated. That one would probably fit through the holding tool.

I tried for two days to get the crankshaft pulley bolt out on my 03 Acura MDX 3.5L. I tried the caveman method with cheater bars, the special crank holder tool, soaking it with Kroil then doing the caveman, heating it with a butane torch, soaking it in Kroil, and doing the caveman -- nothing. I put my beast of an impact driver on it and hammered away. Still nothing. Heated it and impact hammered it. Nope. Frustrated and very sweaty, I went on YouTube and found a video of a guy with a special socket he said was made by "Titan", I think. The socket was a standard 19mm impact socket welded into a larger piece of pipe. He stuck his impact gun with this homemade looking socket on the crank, zipped it, and out came the bolt! I had to have me one of these and I had to have it today (well, tomorrow actually with one day Prime and some extra bucks). I found this one here on Amazon and ordered it. It came this morning. The bolt on my crank is out. That's why I'm writing this glowing review. Amazing. If you're in this situation, I urge you to buy this socket now. Think of the hair you'll save on your head as well as the Xanax you won't need. I have a 3/4" drive 1400 lb./ft. (or so) impact gun with a 3/4" to 1/2" impact drive adapter. The only reason I own this beast is for crank pulley bolts. I put this socket directly on the impact gun (no extensions) and I hit with 100 PSI of regulated air through a 3/8" ID rubber air hose. My compressor is not a large one, a DeWalt that produces 3CFM at 90PSI, I think. I hit it for about a minute, and nothing. I let the compressor catch up. I hit it again for about a minute. Nothing. I let the compressor catch up. The third time, I notice immediately that the gun was spinning faster, and then it broke. Out came the *&(_)^ crank bolt! The socket itself is made in Taiwan, patent pending, comes in a nice plastic bag in a nice cardboard box, it's well finished, and precision machined. Very heavy, which is what makes it work so well. I was very pleased with the quality. Good luck, fellow knucklebusters.

If i hadn't of used this socket myself i would not have believed it, it worked that good. I Purchased this socket to remove a crankshaft bolt on a 2002 accord. My first try was with a Milwaukee fuel 1/2 drive impact with a short 19mm socket and a very short extention, I hammered on that bolt for several minutes and all it did was rotate the engine, it would not remove the crank bolt... what the heck??? I then decided to give this socket a try with the same impact without an extension, and i am not jokin, I didn't even get to count to 3 and that bolt zipped right out like no ones business... ya gotta be jokin i replied...??? I was litteraly shocked how a socket like this could actually do that with the right impact wrench. This socket was the cheapest way to go otherwise it would have took more tools to do this job, so I took a chance and bought it and I'm glad i did. It's like using a bigger hammer, and transfers all the impact to the bolt, not absorbing any impact like a normal socket would do. This socket really does work if you have the right impact wrench to use it on, it takes both tools together though, but when used together it's the perfect solution to a tough bolt. I gave it 5 stars and it well deserved it. I'm still amazed how easy the job was with this socket, cannot speak well enough of it. I'm gonna brag about this little dude for a long time... lol.
