Mower engine won't turn
I have a Ariens mower with a Briggs & Stratton Intek mower. It
appears that the crankshaft will not turn. Here is what happened and what I know so far. I took out the mower for the first time this season. Usually the mower takes 2 or 3 pulls to start. After the 2nd pull I realized that my allergies and headache had the better of me and I was not pulling the rope very hard. So I tried again. The rope came out as usual, the engine didn't start, and the rope went back in. So I grapped it again and when I pulled I found that the rope would not come out. Turns out it won't budge. I assumed that the rewind starter had somehow gotten fouled up since I think in trying to pull hard I pulled too far and the rope handle flew out of my hand. Turns out the rewind starter is just fine. I removed it and it seems ok. So, I held the bail brake and tried turning the flywheel (both with the plug in and with it out) and it won't turn. Next I checked that the flywheel brake was actually disengaging. It appears to work fine. When the bail brake is held, the flywheel brake disengages. However the flywheel will not turn. I still have the flywheel cup and nut attached, so I am assuming that the crankshaft is not turning for some reason. I am very new to engine repairs. So, I could be missing something basic here. The part that has me really curious is how could the crankshaft get stuck from just pulling the rewind cord. Note that the mower previously was working fine and in the first few attempts at starting, the cord pulled normally. Since I was not feeling well, I know it is impossible that I pulled the cord extremely hard. So it doesn't seem that I could have bent the crankshaft. Anyone have any suggestions as to what the problem could be? Thanks, Door |

Is oil level normal, to high and the float might have stuck and hydro locked it up with gas. Once I saw a motor so full of gas when the plug was removed and cord pulled gasolene shot out 10 ft out of the spark plug hole. |

Plug is out and is not oily or wet. Also, the blade does not turn
either. I should have mentioned that. You can not turn the blade, pull the cord when fully assembled, or manually turn the flywheel or cup that attaches it to the crankshaft. The oil is just above the fill line. So, it is about time to add more oil, but the oil is not low (as in not below the fill line). |

He hadn't washed out the deck in 10 years, and the built-up grass deposits had dried out over the winter and flaked loose, jamming the blade tight in the deck. Tipped it over, pulled out hald a bushel of hard dried grass and it started furst pull. |

I've had badly seized engines (from rust on the rings) come free with a mixture of deisel fuel and oil of wintergreen. 1 ounce of oil of wintergreen from your local compounding pharmaist in 1 gallon of deisel will free up a lot of small engines. The stuff is poisonous so you have to sign for it. |

Mower engine won't turn
I'd want to take one last look at the brake (strap around
the flywheel). To be certain sure. If the brake is releasing, and the mower is still locked up, then it's likely not worth fixing. -- Christopher A. Young Learn more about Jesus www.lds.org .. "DanG" wrote in message ... Remove the spark plug. See if you can turn the engine with the blade, you have much more leverage there. Make sure you do have the engine stop disengaged. If the motor is locked up at this point, it may have a broken crank or threw the rod or its cap. Time to get another. -- |

I don't think anyone has suggested this yet but please disconect the spark
plug before trying to turn the motor with the blade. You will need your fingers for the future. This is not a fix for your problem, but a safety issue. "Ulysses" wrote in message ...

Mower engine won't turn
Some very good ideas.
LM, thanks for the good post. I'm looking forward to trying this when I get a chance in the next couple days. There are no lights/battery/generator, so that part is ruled out. On May 26, 11:25 am, "Ulysses" wrote: Is the blade tight? The blade is definitely tight. Have you checked to see if the ignition coil is out of adjustment and jammed against the flywheel? I haven't. Definitely worth checking. Thanks. Also, no one else ran the mower since I have. No one but me has access to the power equipment. I can remove the flywheel brake and see if that helps. I ruled the brake out because it is a pad brake (not a strap brake) and I can see the pad move completely away from the flywheel. If I end up needing to remove the flywheel itself at some point, I'll need to get a flywheel puller and holder. They don't seem to carry those at the local home & garden store. |

Also take a good look at the shaft above the blade and make sure there is no cord, old string, etc tangled up on it. -- There are no stupid questions, but there are lots of stupid answers. Larry Wasserman - Baltimore Maryland - lwasserm(a)sdf. lonestar. org |

Sure looks to me like the engine locked up between the second and third pulls. If someone else killed the engine, it woulda been locked up before the first pull, you think? Agreed. Remove the engine brake completely Keep spark plug out Carefully check to be sure that there is nothing packed under or around the blade. Clean well around crankshaft. Squirt some penetrating oil at base of crankshaft (where it exits engine block) Now, Try to turn blade CY: That's a thought. Locked up where the crank shaft comes out. My best guess is the engine brake isn't really releasing. Note: Does this mower have a built in generator (for lights or charging battery if it has one)? If there is a generator coil, one winding may have come loose and bound up against flywheel. Check for that if there is a generator. (I had that happen once). CY: That musta been some years ago. I've not seen generator except on riding mowers. And the OP did say it was pull start. If it still dont turn, the engine is siezed. Could be the cylinder wall was so dry that just pulling it, caused a piston ring to score the cylinder wall. CY: He did say the oil was slightly overfull. But that doesn't prevent engine siezing. Especially if the oil hadn't been changed in a long time. If this happened, flip the engine upsidedown for a few seconds to get crankcase oil into lower part of cylinder. Then when it's upright again, pour some kerosene (or diesel fuel) and motor oil mixed half an half into the cylinder. Leave it sit for a few hours, and try to turn blade again. Use a wooden mallet if needed against the rear (dull side) of the blade, and tap it. CY: That's a thought. Might be piston siezed. If none of this works, remove the cylinder head. Take a block of wood like a 8 inch piece of 2x2 or chunk of tree branch. Place wood against top of piston and whack the wood with a hammer. If there is a bit of scoring on the cyl wall, this should free it up. Otherwise you likely have a bent or broken connecting rod, crankshaft, or valve. If thats the case, it's time to tear down the whole engine. CY: Or, at that point, to pitch in the scrap and go find another mower. I know a guy who drained the engine oil from a mower in fall, and started it in spring without oil. The piston siezed against the cyl wall. It actually peeled up a small bit of the aluminum cyl wall. He had me look at it. I removed the head and found this. I poured oil all around the piston, let it sit, and whacked the piston with wood block and hammer. It came loose. With the piston all the way down, I used some emery paper and carefully smoothed out the score in the cylinder wall. Then I spun the engine with the blade until it moved freely. I put on a new head gasket, put the head back on, and it fired right up. However, it did smoke quite a bit from oil leaking past rings at that gouge in the cyl wall. He bought a new mower a few weeks later and gave me that old one. I used that old mower for probably 10 years after. The smoke ceased to be real bad after the rings smoothed out that gouge. I also added some of that STP oil treatment to the oil to help lubricate better. CY: I'm the same way. I'll spend an hour or two trying to restore an old mower, rather than pitch it and buy a new one. |

With compression release, now days. It's supposed to make it
easier to pull the engine. I'm sure it does. Two or three pulls to start, that's about the right number. My seldom used generator, I've had to spray some ether on the paper air filter to get it going. Runs for a few seconds, and then dies. Repeat, until it runs. -- Christopher A.

I wonder if the diesel fuel would have worked as well alone. no, we tried it CRC penetrating oil and Marvel Mystery Oil used to have a little wintergreen for fragrance. It seems to me that if wintergreen freed rusty parts, most penetrating oils would have substantial amounts. Oil of wintergreen acts as a "creep agent" as a vapour but it is a poison/health hazard, so will not be a large part of any consumer product The evidence seems anecdotal. One man swears by it because he tried two penetrating oils on a rusty fastener and it didn't come loose, but it came loose after he applied wintergreen. Who's to say it wasn't the oils he applied earlier? Or maybe the wintergreen smell gave him strength! I,ve used it on several seized agricultural engines and got them loose. I've tried just deisel on other engines and didn,t get them loose. Whether diesel was tried first or not, the mix with oow got them loose. Generally takes about 3 days of sitting for a badly deized engine it appears to work particularly well in closed areas like engine cyls. never tried it as a regular penetrating oil. I wonder if it has ever been tested objectively, such as 20 similarly rusty lugnuts, 10 treated with wintergreen and 10 with Liquid Wrench, then unfastened with a torque wrench. Plants produce it as an insecticide, and the odor attracts predatory insects to eat the pests. The typical fatal dose for adults is .5 g/kg. That would be 50g, or 8 teaspoons, for a 100 kg man. The minimum lethal dose for children is .17 g/kg, or less than a teaspoon for a 20 kg child. |

I followed up by pulling the head and found the tip was wedged between the piston and cylinder wall. Figuring I had nothing to lose at tjis ponit I placed a block of wood against the piston and hit it with a hammer. This drove the piston down just enough for the tip of the sparkplug to free up. I got 4 or 5 more years use out of that engine. I would pull the head and take a look. Jimmie |

Is oil level normal, to high and the float might have stuck and hydro locked it up with gas. Once I saw a motor so full of gas when the plug was removed and cord pulled gasolene shot out 10 ft out of the spark plug hole. He already said he tried it with the plug out and it was still locked. What part of that didn't you understand?- Hide quoted text - - Show quoted text - I read it butt head, he didnt try pulling the blade. What part of hydrolock do you comprehend, non I see. *Hydrolock cannot exist with the plug out.- Hide quoted text - - Show quoted text - Sure it can, fill the crankcase. |

A bad carb float or needle valve that doesnt close down can fill the motor crank case completely with gas. |

I've had badly seized engines (from rust on the rings) come free with a mixture of deisel fuel and oil of wintergreen. 1 ounce of oil of wintergreen from your local compounding pharmaist in 1 gallon of deisel will free up a lot of small engines. The stuff is poisonous so you have to sign for it. I wonder if the diesel fuel would have worked as well alone. no, we tried it CRC penetrating oil and Marvel Mystery Oil used to have a little wintergreen for fragrance. It seems to me that if wintergreen freed rusty parts, most penetrating oils would have substantial amounts. Oil of wintergreen acts as a "creep agent" as a vapour but it is a poison/health hazard, so will not be a large part of any consumer product According to a 1994 Material Safety Data Sheet, Ben Gay is 30% wintergreen oil (methyl salicylate). |
