How to Remove (pull) a flywheel on a Briggs and Stratton Engine (any small engine)



In this video i show how to pull a flywheel on a small engine, then my puller broke while trying to show. haha sorry about this. I DO NOT RECCOMEND USING A IMPACT ON A PULLER LIKE I DID, THATS ONE OF THE REASONS IT BROKE, I WILL BE DOING ANOTHER VIDEO SHOWING HOW TO REMOVE FLYWHEELS, THANKS FOR WATCHING, I WILL REDO THIS VIDEO AND DELETE THIS ONE WHEN I GET IT DONE.

  1. What brand and model number is that electric impact wrench. I bought one from Harbor Freight a couple of weeks ago. I haven't used it yet. Mine looks larger than yours and it is to heavy I think. It is rated at 230 ft.lbs. I got it online with a 20% off coupon. Shipping and tax all total $50.00 plus change. Thanks

  2. its chicago electric from harbor freight as well, they have changed them in the last 2 years or so, they are red now, i'm not sure of the model right off hand, they are great wrenches, used them on lug nuts and alot of other things, works great! thats a pretty good deal, we got it on sale in a store for 39 i think it was. thanks for watching!

  3. is that electric impact the harbor freight one?  looks bad for there puller … but good for the impact!  LOL  I need me an electric one so let me know where that ones from… wrench on!

  4. Despite the failure, very good info on fly wheel pulling alternatives. I have a Briggs lawn edger that is getting no spark from the coil/magneto, and need to pull the flywheel to change out the points/condenser. Also good to see a YouTube poster that (at least not on camera) does not rant and rave or spout profanity over this incident (puller failure). Kudos to you, sir. 

  5. I wouldn't use an impact on anything that's cast. Cast iron or aluminum won't be able to handle the vibration given off by the impact. Ratchet would have worked fine. Time consuming, but you'll get it done eventually. Good video.

  6. you know how he said he just pulled the flywheel to take the points and condenser out because he's using a new ignition coil so dose that mean i can get away with using just a new coil??

  7. It takes a lot of honesty and strength to show your failure like that. Most DIYers just wouldn't have posted for fear of ridicule. I think it was actually better to see it that way instead of success. You showed people what can go wrong.

  8. Good video sir. After installing the puller a hard strike to the center bolt head of the puller with a brass hammer will slightly loosen the flywheel so that when you hit it with the impact gun it will come right off.

  9. Thanks for the video I have the same puller and it works great just a bad day on this one but crap happens at the worst moments

  10. Yes, should've used a breaker bar instead of the impact wrench. You can't feel the tension when you go the impact wrench route. However, it broke because it was a harbor freight puller. Chinese garbage. Anybody like myself instantly recognizes the impact wrench as the Harbor Freight brand. Also, all their tool sets have that red plate thing that crumples and shatters in your hand. Jeez, I can smell the toxic oil they use to coat their tools right here through my computer! Same smell that pollutes the air and penetrates your nervous system as soon as you open their front doors. Not bad at all for most applications, but you gotta question the health hazards of their tools. All their power tools also come with an extra set of brushes because you're gonna need them soon after purchase….that is, unless they bust apart before you need to replace them. I don't know how they're allowed to sell their stuff here in the states. OSHA should come down on them. I am convinced the odor in that place is carcinogenic, and I am sure the brush dust from using any of their power tools are also. Mask, double gloves and outdoor use only when using Harbor Freight tools and equipment.

  11. bas mi je milo sto mu je pukao radapciger ili izvlakac.zato sto je glup ko kurac i samo zna da sere.znao sam da ce mu puci cim je uzeo da odvija sa vibro pistoljem.

  12. Cool, I want a puller set like this, now I know to look for a good one.

    I needed to fully remove the crankshaft because it was bent due to hitting a water main (lawn mower). If you need to remove the crankshaft, heres what I did. Remove the oil pan, unbolt the connecting rod from the crankshaft and slide the piston far up inside the cylinder to get it out of the way. Then remove the nut, washer, and cup from the flywheel end of crankshaft, thread nut back on until it is flush with crankshaft (to protect the threads) and carefully hammer away. Seperated flywheel and removed crankshaft all at once.

    On a side note, why the heck doesn't Briggs and Stratton come up with some kind of shear bolt/cotter pin type system to hold the blade on so you don't have to do an engine rebuid everytime you let your girlfriend mow the yard 🙂

  13. How to you keep the flywheel from spinning? I'm trying to do this while it's still mounted to the mower so that hopefully I can test the stator and see if there's a voltage regulator under the flywheel because I can't seem to locate it anywhere else and the guy from JR Rosencrantz insisted that it has to have a voltage regulator,lol

  14. I bought the HF puller and had to thread the screw holes. But on the 3.5 Briggs, the flywheel is smaller and the bolts closer together. I couldn't use the puller and couldn't find my old one either. I was basically going to strip the motor for parts or just tear it down. Idk, the key way is off a hair but not sheared and hard to pull. No oil in the cylinder or much anyway. I did a compression test and it was only 60lbs. I can only guess that the crank is bent.

  15. Man, put that impact wrench away!  I normally make my own pullers but not out of CAST IRON. This one is easy and can be made from a simple piece of angle iron.  Thanks for showing what an impact wrench will do. It IS a good video with a lot of value.

  16. Your video helped me a lot , it showed me what pulller to rent from the auto parts store , it was actually labeled as a harmonic balancer puller . Thanks !

  17. Thank you very much for this video,  I have taken flywheels off before and they were easy.  BUT I am trying to get one off of my Kohler lawnmower engine and it is tough.  SO I came in to see why it does not want to come off.  And I came across this video.  Before this I had no idea the fly wheel could be on so tight.  What am I trying to use to pull the flywheel off with, a Harbor Freight puller of course.  So this video does not look good for my Harbor freight puller.  Thank you again for this video.
