77080 19mm Harmonic Balancer Socket for Honda

If you’ve ever gone up against Honda’s notoriously stubborn harmonic balancer bolt, you know it’s not coming off without a fight. If you’re using an impact wrench, this is the socket you want in your corner. The tolerances are spot-on, gripping the bolt tightly and letting the tool deliver its full punch. Sure, there are cheaper options out there, often bundled with a crank pulley tool, but they’re not even in the same league as this Lisle. I’ve tried one of those budget versions, and the difference is obvious. The tolerance of the 19mm socket is on the large side, more like 19mm “plus a little extra”, which creates play and soaks up impact energy instead of transferring it where it matters. It’s also a versatile addition to the toolbox. While it shines on stubborn harmonic balancer bolts, it’s also useful anywhere a solid, no-slip 19mm socket is critical, especially when you’re putting an impact wrench to work. Bottom line: this socket is worth the extra cost. It performs the way it should and. Its precise fit helps reduce the risk of rounding off that bolt you’re already fighting.

I’ve fought with these infamous Honda crank bolts before and always managed to remove them with a crank locking tool, breaker bar, and force. Finally met my match on one, though… Used heat, PB blaster, extensions, breaker bars, and a regular impact wrench at length, but no dice. I THOUGHT I broke it loose at one one point, but after using a 4 ft cheater bar, throwing everything I had at it, and hearing a BANG!!! like a gunshot, I heard pieces scattering across my garage floor. Looked in the wheel well of the 05 CR-V I was working on expecting to see a broken socket or breaker bar joint, but discovered the flange on the harmonic balancer meant to hold the crank locking tool actually broke off of the balancer face! That’s a first for me. Exasperated, I was about to just go invest in a monster impact wrench and hope it worked, but figured I’d be reasonable and order one of these sockets first. As soon as it came to the house, I put it on my cheap Harbor Freight air impact (I think it’s rated for 600 or so lb. ft torque) and gave it a try… At first, nothing, affirming my doubts. Then I cranked the air supply from 90 something to 125+ psi, and after a couple of ten second or so pulls on the trigger, suddenly I heard the familiar “blat blat blat ZOOOOOOM” of success! I could not believe it. I understand the physics, but it felt like freaking magic. Could not believe, after all the violence I threw at that bolt, a concept as simple as weighted socket on an impact could make THAT much difference. 10/10. Would absolutely recommend. Just wish I would’ve ordered one a long time ago and done something different with those lost bolt fighting hours of my life.

This is the perfect length to use on the crank pulley bolt without the need for any extension. I used it on a 2013 Honda Accord with the 3.5L V6. I spent a day trying to remove the bolt, and broke two breaker bars in the process. Once I got this, the bolt came off with only 2 hammer hits from my Milwaukee 2967-20. This is exactly the tool you need.

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.

I just replaced the timing belt on my Honda Odyssey. As I am not a professional mechanic, I first watched hours of YouTube videos of people doing the same thing. Virtually everyone said that the most dificult part of this job was removing the Honda crankshaft bolt. No one knows what type of soul-crushing wizardry is employed at the Honda factory to tighten that bolt, but it is known to be almost impossible to remove, often breaking tools and hurting people as they tried. In fact, some of the videos that I saw suggested that if you couldn't get that crank bolt off, your mechanical skills weren't worthy of doing the rest of the job and you had best just send back your parts and drop $2K at the Honda dealer's service dept, where the tech will heat that bolt up with a torch to get it off, likely damaging the rubber parts inside the crank pulley, but it's not his car, so he won't care. I saw a couple videos of people using this tool (as well as some heartbreaking ones of people that didn't). Most of them just used their impact wrenches to break this bolt loose in seconds. Didn't look so hard to me, so I ordered this Lisle 77080 socket to get some advantage in my undeclared war against this crankshaft bolt. Fortunately for me, some frugal type had used this particular tool and then sent it back to Amazon, allowing me to get it as a Warehouse Deal item for $5 off or so. Having once been poor myself, I try not to judge, and since I received a benefit from their cheapness, it was a win-win. It's not like the socket could have been damaged or anything. You could run a tank over it and it would be fine. So what IS this thing? It's a 1/2" drive 19mm socket. Wait, you say. You already have a 1/2" 19mm socket? No. You don't have THIS socket. It's easily three times the thickness and weight of your puny Harbor Freight impact socket. The mass of the socket is designed to put more of the bang-bang from your impact tool into the target of your wrath. It's a deceptively simple solution to a problem that many people have found insurmountable. This bit of metal, dropped to Earth by the Engineering gods, claims to be able to loosen that Honda crankshaft pulley bolt without heating, special tools, cursing or Macumba. My experience: I hit the bolt's mating surface with some PB Blaster and went in to have breakfast. An hour or so later, I applied my 120v plug-in Porter-Cable electric impact wrench to the bolt, through that magic socket. For about sixty seconds, the tool bucked in my hands, working as it hammered away at the unyielding bolt. When I started to smell weird electrical smells from my impact wrench, I figured that was enough. Putting the impact wrench aside to cool, I sprayed more liquid slipperyness on the bolt and went inside for a second cup of coffee - a highly recommended perk of early retirement. After thirty minutes, I went out for a hopeful second go at the famous bolt. This time, it didn't last ten seconds before it came spinning off. Easy as freaking pie. If I could do this, you can do this.

Worked for my honda!

A BEAST of an impact socket. Took the harmonic balancer nut off without much trouble at all. Better than a breaker bar when you’re working alone.

Worked absolutely awesome is a little lose fitting but can’t complain to much considering the price

Kiedy klucz udarowy 400 Nm, a później nowy klucz 900 Nm poddał się, widziałem ratunek tylko w tej nasadce. Udało się w okręcić śrubę w D14Z2 w krótką chwilę z pomocą Lisle!

did the job very good

This is a good tool, but was still not enough to remove my crankshaft bolt. I had to use it and a breaker bar and turn the engine over to break the bolt free. Impact drivers did not work for me either air driven or battery.
