Flywheel puller for a briggs and stratton?
I have a 5.5 hp briggs and stratton i'm rebuilding for fun. after
struggling with the flywheel and doing a quick google search I found that i need a special tool to do this right. One sight said it would be easy to make your own flywheel puller with some extra metal and a drill press. I have acess to my highschool auto shop so it would be easy for me. How exactly do these tools work? It might help to have an understanding before I try to make one. Some directions on how to use one would be great. |

Wacking the end of the crankshaft didn't loosen it? I don't know what a 5.5hp B&S is like, but for older ones, all I had to do to remove the flywheel was remove the retaining nut and wack the end of the crankshaft with a big hammer (I protect the end of the crankshaft with a piece of very hard oak). I've never had one yet that didn't pop loose. They were on a taper and the shock always caused them to move up the taper. The 5.5 Hp might be different though. Ed |

If its like mine, there are 2 bolt holes on the top of the flywheel. Drill a stout metal bar with 2 holes the same distance apart as those on the flywheel. Bolt the bar to the flywheel with the center of the bar on top of the crankshaft. Gently and evenly tighten the bolts to pull the flywheel off the shaft. Dave |

Ive seen some that needed the puller torqued up and still had to have a sharp rap to break them. The OP can buy a gear puller for a few bucks which will work fine on this application. When I can buy a tool for a few bucks, I dont waste time trying to build one. Harbor Freight might have a cheap unit. |

I was afraid of messing up something so i didn't hit very hard. I have some blocks of wood and a large metal hammer. I'll try that. |

The good news is the flywheel came off with one sharp wack protected bay a few inches of 2X4. Bad news, does anyone know to remagnetize a flywheel? |

Bad news, does > anyone know to remagnetize a flywheel? Unlikely that your flywheel became unmagnetized. I have never seen it happen. Use fine sandpaper to dress the magnetic insert in the flywheel. Use new points (if this applies) and carefully set the gap and index. Should come up firing. If it is REALLY demagnetized, I have no idea what to tell you. Buy a new one, or find a company that can reenergize your old one. |

I doubt the one whack did it, i had tapped it a few times but something happened. the magnets can't even hold a paper clip now that its off the engine. |

Does this engine have a solid state ignition rather than the magneto type that most of us wout be more familiar with? If it is the old standard magneto type, then clearly you will have to replace the flywheel. |
