Thanks William (Bill?) You know it has been a very social thing for me as well as an education on all things about online video. I have met (on line) many interesting folks. From all walks of life, young and old. Thanks for the great note. Bruce
Great video Bruce. Just came across this one. In the past when dealing with a stuck flywheel like that, I've wrapped a nylon ratchet strap around the bottom of the mower and the flywheel to keep things from "flyin! - just an extra bit of safety. Nicely done.
This was a fun one! Bent blade replaced, clogged air filter, sticky cables, new plug, timing off - sheared flywheel key, oil change... And I see you have your very own magic hammer 13:14!
Wow excellent video Bruce I don't think I ever seen a flywheel pop off a lawn mower like that also very nice to see it in slow motion LOL but all in all good repair 👍👍👍👍
That flywheel didn't want to come off but when it did it sure did come with a bang!!! Nice repair BTW!!! And I agree with you, the mower started pretty good with the key displaced by that much.
Love working on mowers to. New project of mine old lawn Boy brick style mower. Love the slow Mo on the flywheel popping loose. Think you jumped just as high as the flywheel did. Lol! Runs like a top now Bruce.
I love your videos. I have a 4.5hp bolens briggs and stratton. It was have the same issue hard to start. It would run. It had a miss too it. It's a trashed picked mower. I didn't keep the deck because it was rotted. I keep the motor handle bars and wheels and whatever else that could be unbolted from the deck. I found the flywheel key was sheared. The shaft isn't bent It's still stright and true. Just a pretty ding in the blade. Still balanced... I just need to buy a new key and remount the flywheel.. Thanks for your videos...
Hi: Just found you on RU-vid 👍 today, good stuff. Working on my old Honda HRM215 not starting this spring. Like your “Lift Table” , wish I had one.. Thanks
Great video bruce .... how wide is yr lawn/snowblower lift . Im looking in to buying something im killing my back on the floor and i get alot dirtier aswell . Let me kniw thanks #smallenginenation #keepwrenchin
That was quite a show when the flywheel popped off. If you use a piece of wood to hit on against the crankshaft, use a piece of hardwood . That pine took all of the shock instead of the crank. Of course you don't need it with your air-hammer. Good video Bruce
Man that was the tightest one I’ve seen. Owner is lucky crank wasn’t bent. My Briggs electric start curb find ran a little lumpy. Searched hi and low, finally, slightly sheared key. The key way is where the key goes, the key is what’s sheared. No sheared keyways! Good job! From s Fla where its77 F, partly cloudy and 52 %humidity. Wish you were here to hang out.
I had a mower that ran all summer, when spring came it wouldn't start, took it all apart, found same problem as the one you just worked on. Flywheel key sheared and flywheel had shifted over just that width of key to cause it not to run. Took me a while to figure it out as it had run right up to putting it away for winter. When you said it hit the curb, my thought was I wonder if key sheared. LOL! good tip about heating the center of flywheel. Thanks.
I sweep with a wide course broom, then I blow the dust out the two big doors with a leaf blower. About 3 times a year I use a pressure washer to get the crud??? out of the corners. I need a clean floor so when I drop small things (which i do all the time) I can find them. Plus all my major tools are on wheels so i can roll them around without catching little obstacles. . Thanks for noticing James
Another great video Bruce. I reckon people from all around the globe jumped when that flywheel popped off, i know i certainly did. Ooh, is that a Honda i spy in the to do que??? Looking foward to that one. Cheers from downunder where we dont have any snow lying about, and are in the middle of a quite pronounced drought. Mike.
Thanks. The Honda was last week. Here is part 1 ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-ygVsGxXIbpI.html And Part 2 ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-6Dv3LCWpK2c.html
@@BrucesShop No sir, not Canadian, but I am aware that Monday is Thanksgiving in your corner of the world. Just giving thanks for all that you've done for us 'Tubers.
Great fix Inspector. Interesting that it started and ran with the key sheared. That is first one I saw sheared that much and ran. I have had a few Briggs and Tecumsehs with ever so slightly bent and they wouldn't run or have the rope yanked out of your hand. I will try the heat trick on my next Briggs flywheel pull. Thanks for the tip. You might need a hockey mask for the next one. Stay safe my friend.
Another happy lawnmower. That funny one little part could throw you off checking everything else but not flywheel key and yeah it nice to have the right tools for the jobs
When ever I come across a mower that has had a blade impact, I first check to see if there is a bent shaft and second would be to check for a sheared key.
Great Job as always Bruce. One thing I like a bout your work is that you always clean the mower I can remember a few years ago I took my Dads Kubota lawn tractor to the shop for a problem it had while there he said have them go ahead and clean the mower deck and sharpen the blades. well they sharpened the blades but did not clean the mower deck and I said to the guy when I dropped it off Clean the deck and sharpen the blades I hate it when a shop does a job half way and this was the Kubota dealer. You take pride in your work and I like that thats how everyone should be. I'M not a fan of the front wheel drive self propelled push mowers They don't work that well compared to rear wheel drive self propelled mowers. I notice bruce you don't work on riding mowers do you? Have a great weekend. God Bless!!!
It is my age. Working on a lawn tractor means laying on the ground. I do about 5 or 6 a year. I do film a few but being "not young:" they are a challenge. They are like a car, working on the ground most of the time. You know as well, I like to work on clean equipment. Once you get onto that is just makes sense. Although at -20 they have to be wiped down. The outside hoses are all frozen so the pressure washer is of no use.
I can under stand that even at my age it is getting more difficult for to get up and down working on my own equipment zero turn and large commercial walk behind mowers I have a back issue and arthritis in my right hip.
great videos. i have a craftsman mower with electric start., neighbors dog chewed the wires to the electric start . it had a 40amp fuse . how do you rewire the electric start?
You should be able to follow the colour of the wires Take in a sample of the wire to a good hardware store and splice them back up. just do one colour at a time.
That was an interesting job...lots of things to investigate. I bet the owner was well pleased, it must be like having a new mower considering all of the issues it had.
Your Diagnostic abilities were apparently thrown off by by not fastening both straps of your overalls. This is an often overlooked mistake by the finest repair men.
Looking back on some old ‘ Doc Mower ‘ vids, and I think when you first tried running it, Bruce, and you took the closeup of the throttle assembly, if you listened carefully you could hear the engine knocking or pinging from the advanced spark/broken key. Interesting. Looked like there was 20+ odd degrees of advance with the broken key/ flywheel positioning. They’re a pretty tolerant engine. Cheers from downunderneath where we are finally getting some cooler weather, Mike.
Jump start your heart! That's one way to do it. It's like cranking on an old Jack in the Box, knowing it's going to pop up, but still being startled every time it does. Great repairs! Did you think to use the cable lubricator I sent you for the cables? They really make short work of the job. Cheers my Friend! Sean~
Yes I do use it a lot. It is a bit hard to fit on the end with the clamp. I used it on a cracked one last weekand the fluid came right to the crack from both ends. Not the best repair as I used a cracked cable but saved money on the cable.
Hello Mr Bruce ,from Thunder Bay ON. yesterday I got a machine same as that one, I thought will be easy to fix cus got a bend blade, has spark clean oil, clean carb, even blade looks new, but does not fire at all, what would be the problem ? motor ,or valve? when is the key cranks, but this not a sound.
@@BrucesShop I did stupid thing ,I busted the nut that holds the flywheel,I used impact gun,I hope I will b able to put a new nut with smaller size,ya that key looks broken.
cool video i guessed the key on the first start lol i know those are no pron to shearing as the old ones but they do its cool that it started with that key sheared is the snow gone or is this an older video you looked warmer lol
We still have some on the ground. Our Canadian Thanksgiving is this weekend. I still want to cut the lawn but some of it is under snow. We have an early thanksgiving compared to the states as our weather goes bad before yours does Thanks HD.
Loved the video and had the same thing happen to me with a stuck flywheel tried the wedge didnt work then the 3 jaw puller and never though to use heat and it broke in half but had a spare and next time i will use heat so thanks for that Bruce
Nice fix! Front wheel drive best way to go for me. I got rear wheel and much prefer front cause when it's not under wheel engagement or even if it is ,,,, it is so much easier to maneuver the mower
At the very end you took the gas cap off after priming it and it started. Whenever I do that it won't start. I have to re-prime it. I don't know why. Very good video, Bruce.
great job on the repair bruceyour reaction to the flywheel coming loose was awesome,i liked that compression trick you showed,i did not know that,did you use the cable lubricator to lube the cables
Briggs is one of the few that will run with a completely sheared key, I even had one that had diesel in it and it ran , not good but it ran. ! :-) And as the one viewer said about the blade that's a sure bet on a sheared key .
Really enjoyed you finding and fix the key way , also when the fly wheel went for your throat..ha ha .. Excellent repair ?...... Oh can l ask you, a question ,.... Can you Whistle !........ BECAUSE You sure can't sing ,?
Flywheel key .. that was a big blade hit .. I have to use my OTC “Hub Grappler” to pull the flywheel .. give the drive screw a few cranks, the tap the flywheel with plastic hammer .. repeat .. .. the heat works great too.
Bruce, please do your work from the far side of the mower. You were standing in front of the camera when putting the flywheel back on. I know how to do it but other people who haven't seen that done will appreciate it. Thanks for closing the garage door. You are getting the hang of lighting. :>)
Yes but then I am working with the mower in front of me looking into the camera. It is harder to do than you think. All I can say is that I challenge you to make a video and edit it with Movie Maker. Then revisit this video. I am working on this issue but when i get into the problem mentally the problem becomes more of an issue than the video. I realise it is my bad.
I understand. It's hard to stay out of the way when you have to focus on something. You're also trying to plan ahead at the same time so as not to waste a bunch of time AND not make any mistakes. It's like juggling four tennis balls!
aka GrincheyOne. Fine job as always Bruce. I see you use an "ezzy pour" spout on your gas can. It seems that every restocking season at Walmart, The "no spill" spouts changed (and never worked for very long, if at all).
Better be careful laying over, the large back wheels aren't engineered for supporting the weight sideways and those SOBs can cost over $60/ea. if you can find them that cheap. The front ones aren't cheap either. I've got a close cousin of that mower, identical but for paint and labeling.
Dear Bruce, it was you who taught us what to do first 😂👍 How could it happen that you missed to check the flywheel first. Never mind, you are still my teacher. Have a nice weekend! There’s no snow anymore in your surroundings, right?
That WAS scary. I'm going out and buying a face shield tomorrow, just to wear around the house! Was that one of the pieces of key that flew off and landed on the deck, to the right of the Danger sticker? Impressive instincts, with both the face shield and the heat!
Surprised the crank seal is still good... Smacked a tree root once at the end of the mow and put the mower away,minor vibration, so I got another blade,next time I went to use it, there was a puddle of oil on the floor. So much for the new blade...never installed
I've seen bent blades before but WOOOOW that was bad. A lot of people lose there minds over the "engine /motor " thing and I get it but why then is Detroit the motor city or motorcycle or even motor vehicle. Anyway awesome fix my man
I was thinking maybe drilling a small hole through the side of the plastic cable tubing and injecting white lithium grease through it would work better than lubing only the ends (?). Then plug it with putty or clay... It's an idea anyway.
I have a cable lube injector. This is it. Did you see the flywheel come off at 16:00 That was the reason for the video. www.amazon.ca/cable-oiler-lubricator-clutch-KiWAV/dp/B009YEYL0I
Are you certain you used a ten MILLIMETER business card (20:38 in the video) to set the air gap on the coil? I normally go with a .010 inch card myself! Lol Gettin' old ain't fer sissies, is it, Bruce? I know ...I do those things myself!
yes. In my last video in which I did this. I measured the exact width of this card and It came to .0010. In the following video at 5:40 in the attached video below (not the one above).. I have had the gap to 1/8th of and inch they and still run. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-h3T02rSXMZk.html
Looks like you got all discombobulated when that flywheel came loose. 😨 Fun to watch, but not so great to experience. I bet the broken key was acting like a wedge, giving extra tightness. I saw a guy smack his 3-jaw puller (with a rawhide mallet) when he used it like you did. (I wonder if he's had to replace the puller yet.) Yuh did good. 👏
Yes! Harder metal. I got me a textbook from 1998, "Small Engine Technology," by William A. Schuster, that indicates, if you were to retrofit an ignition coil with a Briggs & Stratton "Magnetron (R)" coil, you also have to replace the flywheel key with a harder key. So, I assume newer B&S engines all have a "Magnetron" coil (or a newer generation of same) and, therefore, have harder keys than would be found on a Tecumseh engine. QED . . . or quid pro quo, or et in Arcadia ego, or some such Latin phrase.
By the way; it took me three days to find a way to loosen the blade adapter which was heavily bent when my father in law hit a hydrant head which was hidden in the grass.
To get all my flywheels of I use one of the metal fins on flywheel and have it against the coil metal holes part then I put nut on end of crankshaft and pry underneath and use brass hammer on top of nut and it comes right off.
I use a wood splitting wedge, strategically placed under the magnet area on the flywheel. I gently tap it in, then gently tap the crank snout. I haven't broken or bent anything yet.
