I just changed the timing belt on my Honda Odyssey. Not being a professional mechanic, I first spent hours watching YouTube videos of people doing the exact same thing. Almost everyone said that the hardest part of this job was removing the Honda crankshaft bolt. No one knows what heartbreaking magic is used at the Honda factory to tighten this bolt, but it is known to be nearly impossible to remove, often breaking tools and injuring people attempting to do so. I've seen the suggestion that if you can't loosen that crankshaft bolt your mechanical skills aren't up to the rest of the job and your best bet is to just send your parts back and throw $2,000 at a Honda dealership's service department where a technician heats up that bolt burner to remove it, probably damaging the rubber parts in the crank pulley, but it's not his car so he doesn't care. I've seen a few videos of people using this tool (as well as some heartbreaking stories from people who didn't). Most of them just used their impact wrenches to unscrew that bolt in seconds. I wasn't looking for it too much so I ordered this Lisle 77080 head to get a head start in my undeclared war on this crankshaft bolt. Luckily for me, a frugal guy used this particular tool and then shipped it back to Revain so I could get it as a Warehouse Deal item for about $5 off. When I was poor myself, I try not to judge, and since I benefited from their cheapness, it was a win-win option. It doesn't look like the socket is damaged or anything. You can drive a tank over it and you'll be fine. What is this thing? This is a 1/2" 19mm socket. Wait, you say. Already have a 1/2" 19mm socket? no You don't have THAT outlet. It's three times thicker and weighs more than your fragile Harbor Freight impact head. The mass of the nest is calculated to give more impact to the target of your rage. This is a deceptively simple solution to a problem many find insurmountable. Dropped to earth by the gods of engineering, this hunk of metal claims to be able to loosen a bolt on a Honda crankshaft pulley without heat, special tools, curses, or Macumba. Breakfast. About an hour later, I put my Porter-Cable 120V electric impact wrench through that magic socket onto the bolt. For about sixty seconds the tool stepped into my hands and worked to knock out the unyielding bolt. When I smelled a strange smell of electricity coming from the impact wrench, I decided enough was enough. I set the impact wrench aside to cool, splashed the bolt with the still-runny, slippery liquid, and went in for a second cup of coffee—a highly recommended early retirement perk. Thirty minutes later I headed for the second run on the famous bolt full of hope. This time it didn't even take ten seconds for it to spin. If I could, you can do it.
