Why do I not believe this . . . ? Maybe because it's on the internet? Denial? Every time I see some There is a proceedure in the Factory Service Manual. It works very well. Wedge a screwdriver as shown, and get a big breaker bar with a 17mm, 6 point, impact socket. Johnny Mullet has a pneumatic impact wrench that never fails. The torque spec on that bolt is 81 foot pounds. The "Rope Trick" is likely to crack a piston. The "2 X 4" method is likely to damage a rod bearing. Think about what you're doing and what potential damage you could do. FWIW. IMHO. GG ![]() ![]() |

Why would you not believe it, that's the recommended procedure as far as I'm concerned. Wouldn't do it with a ratchet, use a breaker bar. Wouldn't hammer on a ratchet either. |

That little hammer is not going to bust any nut loose. The starter method I use if my impact does not do it. Only once that happened.

I purchased a used Japanese engine / transmission a few years ago from an importer. The guy that sold me the engine told me that if I had any problems, he would help. When it came down to switching the sprockets, I could not remove the crank bolt from the old engine. The block was almost completely disassembled and out of the car. I took the block to the importer for help. First they tried the impact hammers with no luck Then they tried a wrench with no luck. Then they used a sledge hammer with a long wrench. After beating on it for about 5 minutes, they finally got it loose! lol |

I've used the starter lots of times but it doesn't always work. When it is really stubborn I lock the flywheel and then I take a good box end wrench on the crankbolt at about the 5 oclock position and jack up on it with my floor jack. The box end wrench is safer than a wratchet because it's more straight inline with the bolt and won't twist off as easy. I've had the car come up off the jackstand before it broke loose. Whenever I pull an engine the crankbolt is one of the first things that gets loosened so i don't have to fight with it on the engine stand. Ken.... |

The rope method has been around for ages and used on anything with an engine, cars, bikes, boats... Personally, I would use the rope method before wedging a screwdriver in the ring gear as I've seen teeth break before. There's alot more mass in a piston than on one of those little teeth. http://geometroforum.com/single/?p=615131&t=4702604 |

The starter method might work to remove it (I never had to resort to it) but it dont do a thing for putting it back on! A man could get him a spare pulley from the junkyard and unbolt and remove the pulley from the crank shaft and using the one he got from the junkyard, weld him a piece of flat steel across the pulley and bolt it up and use it to break the crank bolt. Metros are not that bad but some crank bolts are really tight and hard to remove. |

1/2 inch ratchet with a 17 mm six sided socket. Add a 3 door breaker to the ratchet and all will be well. I don't like the starter method. Too risky, personal injury if the ratchet falls off the nut and gets flung around. |
