I don't own a push mower but I work on them for friends who cant. I learned something I may have to use later. Thanks for sharing your knowledge.
A 15/16 six point socket will work just fine 😊
Thanks for the tip on getting flywheel nut off. I didn't have my drill with me. So I go to TH-cam. It was like my phone read my mind because soon as I turned on TH-cam there you was and I watch for a minute I really appreciate that thank you sir. I usually use my impact drill.
Glad I could help
I found the nut on my Aldi cheapie mower was the same size as my wheel brace. Nice to see a field vid without too many specialist tools.
Thanks for a tutorial brother, very informative.
Thanks very much for this video, Jeff! Although I stop the opposite end of crankshafts on chainsaws and other 2-stroke engines to remove flywheels and clutches it never occurred to me to do the same on mowers to torque the flywheel nut down. Of course now that I think about it, there’s no reason not to do the same thing to remove the nut. I wouldn’t hit a ratchet wrench that way for fear of breaking it but I might give that a try with my 1/2 inch breaker bar first before resorting to blocking the blade.
One other thing I might mention is that you tipped the mower over on the carb/air filter side, which on many engines is a mistake due to oil from the crankcase spilling out into the intake.
Subbed.
Thanks for the comment friend! Thanks for watching
Great video!
Thanks for the visit!
Thanks Jeff.....I am sure my mower problem is a flywheel key needing replacement. Same situation after hitting a hard object.
Those flywheel keys have been a feature on B&S engines as far back as I can remember, they're known as "soft keys" because of the ease in which they shear when an object is struck with a lot of force by the blade, supposedly to keep the crankshaft from bending.
Theyre actually really nice. Some older hondas dont have them and that expensive honda turns to junk
Thanks a lot, very helpful video…
Thank you Jeff!!
Thank you. I learned a lot from your video.
Ok....now I can tighten this Snapper fly wheel down. I did a piece of wood but I think I need to get it just right. Shoot maybe just spend the 25.00 for those blade stop do hickies. Thanks Jeff. Can't wait for more when your up to it. Love the TShirts
Thanks for watching Matt and for supporting Jeff's Little Engine Service
I buy them with bend crank shaft because I have equipment to straighten it back and resale it
Love it when I buy 10.00 bucks for one that’s brand new
NICE!
Very good video, thank you.
Thank you! The tips on getting it all apart are especially helpful.
I used a 15/16" socket and it fit just fine on the flywheel nut
I used a 1" socket on my 6.5 B&S. fit snug came right off with the wood block underneath
Great video, thanks Jeff!
Glad you liked it, thanks for watching
Hope this is my problem with my Troy built push mower. Struck the base of a fire hydrant and bent the blade. Now it won't start, but did start directly after the damage, and would not shut down right away. Wish me luck!
Great!!
Look like there its difficult to take a plate of steel, bore to hols , an to skrews , feeted it them in the flyweel and pull it up
It happen to me the video is correct ,my comment is that the key way is made from aluminum so it will be easy to be cut when it jam to stone or other .
Excellent presentation. How to verify a correct coil-magneto gap? Anyone know?
.010 air gap
hit a stump with rider key is not sheared but backfiring and little power any suggestions
I replaced my flywheel key due to popping and backfiring and now it cranks but won’t even start now.. could the timing be off?
At 7:45 "certain torque" that means one of three torque values: German torque (guten night (good and tight)), fart torque (torque till you fart) and smoked.
I believe I got the same problem with my craftsman lawnmower. Thank you for sharing.
Really good explanation. Very helpful. One point though..... you should have taken off the spark plug cap to prevent accidental engine start. Cheers.
Good tip! Safety is always a good idea
@@jeffslawnmowerrepairandservice just as a heads up, there is a tool to hold the cutting blade in place for easy removal and can be useful for removing the fly wheel nut .... it's the "Atlas Blade Removal Tool for Lawn Mowers or Tractors ". It's sold at Walmart or Lowes, here in Canada we get it at Canadian Tire for about $14.99.
👍🏻
I need that tool to get my flywheel off cause I done a lot and it wont start wont hurt to check it
You can get by without it. Get a screwdriver or prybar and pry up on the flywheel while you hit the flywheel nut with a hammer. Just make sure the flywheel nut is flush with the threads so they don't get hit.
Very helpful, but where can I buy a knockoff tool?
your local lawnmower repair shop or on the internet.
what about the bent blade?
Gotta replace that!
Are the flywheel keys for these engines pretty much all the same?
many Briggs keys are the same
👏🏽👏🏽👏🏽👍🏽
Dumb question. Do I need to drain any of the fluids out of it before I start this project?
no
Lawnmower Repair and Service Maintenance Tips thank you. Also, what if the key is just slightly scratched? I got mine out finally but it doesn’t seemed to be warped, just a couple small scratches?
Lawnmower Repair and Service Maintenance Tips disregard that last message. I put it all back together using the slightly scarred key and she started right up. Crazy
Where to buy a new flywheel key?
The flywheel stow!!!
y`ou may want to take plugwire off, just in case.
good tip
Socket size and Bolt size is not the same thing...
good point
At least remove the spark plug cable when you do this. Disengaging the brake looks even less safe. But good tutorial otherwise.
Good tip! Safety is important.
Where to get knockout tool
Amazon or Ebay or your local lawnmower repair shop
Lawnmower Repair and Service Maintenance Tips I checked amazon . I’ll check eBay. Being in Canada makes it a bit harder to find some specialty tools for a reasonable price ! Thank you .
