I give ya credit, you fixed it. When I was a kid, I drove over a water shutoff, and bent the crank. If I would have tried this, it may have saved my parents from buying a new mower. Lighten up people, it's a damn mower, either way a new crank is almost the cost of the new mower.
I have THREE JD lawn mowers which I cannot use for having bent shaft. Each time I was told that I would have to replace the whole motor, so A new mower was purchased. NOW I will try to repair one tomorrow. You have given me hope that I will not have to replace my mowers every year or so. ( Five mowers in five years, three with bent crankshafts.)
Like I just told nickernosher I had nothing to lose. It was ether this or they buy a new mower. Its still running and the people told me it never has run so smooth. Thanks for the comments.
Thanks for the vid. Recently picked up a bent crank John Deere JS48 (briggs and stratton 875 engine) for $0 that had less than 10 hrs use from new. 15 or so good whacks from my sledgehammer and a good eye it was 'fixed'. No vibration at all. A+++ will recneck repair again.
Wow I can't believe this worked for me. Ran over a hard stump and the crank shaft bent really badly to the point it wasnt able to turn over with the pull start. Did this method still wasnt able to get it straight, so I took off the blade and the holder and I had to torch the tip for a few mins and then gave it a good hard hit and it straightened out better then normal. Thanks for the tip!
Hit rock, heavy craftsmen 4.75hp. bent the blade bad, mangled it, took it off, and motor wouldn't let me pull cord hardly at all, BENT SHAFT. you tube helps again, thx for vid. I used that cool trick of the pointer on a log to center it, then wacked shaft with sledge, with blade off. this let me hit it at a little different angle than on the side of the blade. I then straightened blade with sledge mostly, then put it on, then bent it better with big pipe wrench on ends. runs with slight vibe
well i did it . I had to give it a few more whacks than in the vid and I couldnt get it perfectly straight but i did get it better than before. The mower runs well with much less vibration , just a small amount. It is a Honda mower and engine, that crank is hard, i couldnt get it to bend back easy as you did.
You may not recommend doing it but I did (took the blade off first) with a regular hammer... and worked!!! LOL! Lawnmower working like a charm now. Thanks
Thanks for this video! I was able to save my lawn mower (and about $400) by fixing it using this method! My only investment was buying a sledge hammer. I wound up taking the blade off of it first, and beating on the squared bushing that you bolt the blade onto. It took a fair bit longer than yours (shaft was a bit more bent), but I got it done.
Inspired by your banging with a hammer, I checked out my mower and found it had a bent shaft and with a couple of good solid blows it is largely straightened out. Now it runs as smooth as silk. Main problem was getting a solid hit without bouncing the hammer off of the deck. Just hope I didn't crack the crank or damage the bearings. Still that is better than disposing of an otherwise good mower.
Good result! I had the same problem on honda, I changed Cranked shaft and oil sealing gland, it was a half prise of this honda. The belt gear has jumped on some teeth and tab of Cranked shaft was destroyed. It was result of catching of a metal pipe.
"Runs as sweet as a nut"... You should be proud of yourself. Years ago we would have called this: "precision blacksmithing". It's as good a job as it needs to be... The more you practice; the luckier you will get.
nice work. thanks for the video. my briggs and stratton is doing the same thing. I going to check the blade for alignment and also the shaft. thanks And God bless you.
due to the mechanics of a blade striking an object it will most likely bend the shaft in a direction such that you can strike the side of the blade as was seen in this video.
All long shaft mowers are prone to this damage. But, I have even fixed the short shaft Toros with bent crank. You absolutely have to out them on a lathe and use torch heat to bring them in. Often it is just better to replace the crank. labor cost can get out of hand real quick. But, then again, my mower repair days were over 35 years ago.
Been There Done That. You need to remove the blade (but keep the blade mount on) so you can hit from any direction with the hammer. With the blade on, you can only hit from 2 directions.
And just waht kind of force do you think it had on it when it hit the metal pipe? I did warn not to try this. It worked and the people didn't have to buy a new mower, so they had nothing to lose and I put $40 bucks in my pocket. I would have used a pipe on the end of the crank but I didn't have any way of holding the engine. Thank for the comment anyway.
The flathead motors have the crankcase pressure pipe alongside the muffler.Keep it up so oil wont travel over to the carb.side and possibly hydraulic lock engine. If your not sure if yours is a flathead ,just drain the oil,and eliminate all question.
Here's where swing back blades are useful. Instead of bending the crank it will allow for the blade to kick in from the impact. Having the stiff fixed setup is going to have this end result every day of the week.
@MarkLGandy If you can find a way to hold the lawnmower try using a long pipe on the end of the shaft after you remove the blade. I think it would work better and be more controlled. If it was free it will be fun ether way lol
My Quantum engine uses the same filter. What i found was B+S said it used a prefilter foam pad. I guess it was missing when new. Those things load up fast and the foam slows it down. They also told me do NOT oil the foam. Hope this helps.
Before that I could feel it hitting inside on the case. I was just lucky it worked. Everyone said just to throw it away and buy a new one. Seemed kind of a wast. There was another guy that said he could fix it but he was going to do almost the same thing. All's well that ended well.
had a Briggs/Stratton for just over THIRTY-EIGHT YEARS with 3.5 hp {Murray} mower ran/worked well/hit close to 300 rocks, steel beams, 3" logs that stopped engine dead = never bent the crank or broke any part of the engine, (finally just wore out). NOW with FOUR MURRAY / BRIGGS/STRATTON - 5# +/- TORQUE = TWO DIDN'T HAVE ENOUGH POWER TO GET OUT OF WET PAPER BAG - ONE HIT A 2" LOG X 8" =KILLED ENGINE AND FIVE PIECES FLEW OFF OF MOTOR, LAST ONE HIT A 3" ROCK = KILLED ENGINE - BROKE BOTTOM OF ENGINE(SUMP) - BENT CRANKSHAFT - OTHER BROKEN PARTS ?? YET ""WARRENTEE WILL NOT COVER ANY OF THIS 'FIVE WEEK OLD NEW' ENGINE"". AND TO ADD SALT TO THE PAINFUL WOUND IT IS PAST THE 30 DAY RETURN PERIOD TO "WALMART". the FOUR LAST ENGINES SPOKEN OF HERE THE FIRST THREE WERE UNDER 30 DAY RETURN PERIOD EXCEPT THE LAST ONE. BRIGGS AND STRATTON SMALL ENGINES ARE SIMPLY NOT WHAT THEY WERE A WHILE BACK. HOW ABOUT GETTING THE OLDER "MAYTAG" GROUP OF PEOPLE BUILDING MOWERS. regards,
I got lucky. I would take the blade off if its in the way. Maybe put the bolt back in or get someone to hold onto it while you pull the pullcord with the spark plug out. It will turn over easyer
@91fatboy51 I got lucky. I would take the blade off if its in the way. Maybe put the bolt back in or get someone to hold onto it while you pull the pullcord with the spark plug out. It will turn over easyer
Just god-smacked my Craftsman self-propel, electric key start mower. It starts and runs, lower rpm/ power and nearly quits if you load it by trying to cut grass. Hhhhmmm? I spun the blade and did not see obvious bent shaft. Shop said shaft is about $20, but about an hour labor - $62 if that is what is needed. I rebuilt my Volvo B20B engine, wonder if I can do this myself. New, these mowers are about $369. It also has some other noises when running. It hit hard on a stump, quit instantly, so surprised it runs at all. Winter project! Waiting to hear from shoo next week.
I straightened the drive shaft of a Chevy van with a sledgehammer ran fine after that I was surprised myself of a so easy to do I figured I couldn't make it any worse and it fixed it it's like the old joke just get a bigger hammer not that much of a joke sometimes
If all of the 'wet sock' and any other debris has been removed from the blade and shaft, and it shakes more than before, then there is a good chance the shaft is bent. You could remove and check the 'balance' of the blade to be sure. Hang the blade with a screw driver through the center hole. If it consistently drops more to one side, then the blade needs to be sharpened a little more on that side to remove weight. Unbalanced blade can cause a shake as well as a bent shaft. Check that first.
Just proof that Briggs & Stratton has gotten cheap compared to the old ones. I have straightened many of these shafts and me and a friend took one to work and used a hydraulic press, and it snapped right off before it would bend at all. They used to be made of cast iron, and if you can bend it with a sledge hammer, they must be made of steel now. What I do is heat them up in the coal fire until the shaft is glowing yellow and then use the hydraulic press, then I check it in the lathe with centers only and use a dial gauge. It is a time consuming job.
+Paul Crissman Been sledge hammering for 30 years. Works for me quicker than my old crank machine straightening tool way. Needs to not do it with the blade on. Needs a thick collar to protect it while hammering.
if im not mistaken these all have wear sleeves, no crank bearings. either way i myself have never gotten one to bend back but i was always afraid of cracking the sleeve or lower pan. he had the special touch
@ShawnCFarm haha. all i had to do to myne was hit the shaft 6 times with a sledge and replace the oil seal cause it chewed up the old one lol. other than that it runs fine.
I was wondering why not use a very soft key to attach the blade to the shaft. I would prefer to have to replace the key than to bang on the shaft. With the work I do I imagine I would have to replace a half dozen keys per year.
@workensmart dealer cost is 62 dollars for a 12h802 0115 from magneto power.....honda on the other hand is 45 list price for a new crank......good ol jap steel is cheap
There has to be Angels looking out for Farmers. Some of the things I've seen done to keep stuff running are pretty scary. The term "Haywire" came from somewhere didn't it.
@chevyladtallyhoe That would be cool on a bike. Your right theres all kinds in the junk yard. On the other hand it would make a good video. I know someone that had one that bent before. He took the crank out and sraightened it on the ground with a hammer of all thing lol
The way those cranks are made, you are risking alot doing that. The metal is powdered and put in a mold, then heated till it melts. It is not turned from a sold chunk of metal like they used to. On the older ones, yes you can get away with it. That crank was really bent. If you cracked it and didt know it, that crank will explode. Selling it is a really bad idea. Yes, the seal will leak even if you try really hard to make it right.
Be careful when doing this though. I did this on my 1995 Briggs & Stratton 3.75 lawn mower engine. This sledgehammer repair ended up loosening up one of my connecting rod bolts. The rod ended up braking, thus destroying the block.
You done fixed it? Well I'll be damned. Scooter told me it couldn't be fixed. 'Course Scooter is about as shiftless as one poor son of a bitch can be. You done fixed it. I'll just be damned.
I got a yardman lawn mower I had her 2 year nail I was mowing the other day and hit a tree stump and bent the crank and the blade is bent two and she is leaking oil down throw the crank what do you think I could of done two her.
WARNING THE CRANK IS NOT TO STRAIGHTENED REPLACE IT YOU ARE SETTING YOUR SELF UP TO BE SUED. IF ANYBODY WANTS TO CHECK IF THE CRANK TAKE A MEASUREMENT FROM THE SIDE OF THE DECK TO THE TIP OF BLADE ROTATE AND CHECKING THE OTHER SIDE OF THE TIP TO THE SAME POINT ON THE DECK DUHH!!!!
My dad taught me as a young boy if I ever see hammer marks on an engine it was worked on by a Fool~!!! I had to stop watching when I saw you bring out that large sledge hammer.
This is exactly how NOT to fix a bent shaft. You can do further damage to the engine by hitting with a hammer. I would personally not trust this guy with my mower.
The main hazard I see here is the force you are applying is being carried into the motor casing and you run the risk of damaging the case and/or the bearings. if you could put a block of wood between the engine and the applied blow with that block bearing against the ground, you would take out the applied load and transmit it to the ground. That may require dismounting the engine from the deck.
I give ya credit, you fixed it. When I was a kid, I drove over a water shutoff, and bent the crank. If I would have tried this, it may have saved my parents from buying a new mower. Lighten up people, it's a damn mower, either way a new crank is almost the cost of the new mower.
For a little inginuity and a lot of hammer, you saved the customer a lawnmower. Great job.

Aside from damaging the crank bearing and bearing bore in the block, this is an awesome way to accomplish this particular "repair".
zombieresponder It was junk anyway but is still going now.
+zombieresponder It was already damaged from the bending of the shaft. Damaged unit from now on. No warranty
The repair costs more than my mower so i'll be "Red-necking" my crankshaft too ...Love it Thanks for the vid Bud !

Thanks for cutting the shit out of your hand. I probably would've done the same thing if I hadn't seen that.
@MarkLGandy you are right also why not take the blade off .
I've done several like this successfully with the first one lasting over five years
"Runs as sweet as a nut"... You should be proud of yourself. Years ago we would have called this: "precision blacksmithing". It's as good a job as it needs to be... The more you practice; the luckier you will get.
Love your dial indicator great job

Dude i goter done to bricks rather than a slege but thanks heeps u just saved me money ur ok i my books bro
I hope no sledge hammers were harmed in the making of this movie
That binding/grinding you heard when you turned the shaft was the dead man's kill switch/flywheel brake.

@MarkLGandy Yes your right as you can see when I start it up.
Very resourseful solution.
you can already notice it, if you look at both blade ends, one is closer to the deck and the other is further.
Thanks. I had nothing to loss and it works.
Wish I’d seen this 3 days ago, I just tossed a Troy-bilt with a bent shaft! LOL!

You don't need a dial indicator to see that's bent, wow!
+riphaven Dial indicator would have been nice but I bet I could not get it perfect doing it this way lol
Good job either way. I just hope that bearing holds up over time from the pounding.
if im not mistaken these all have wear sleeves, no crank bearings. either way i myself have never gotten one to bend back but i was always afraid of cracking the sleeve or lower pan. he had the special touch
yup, you can feel it too when the mower asks you to dance with it.
@ShawnCFarm haha. all i had to do to myne was hit the shaft 6 times with a sledge and replace the oil seal cause it chewed up the old one lol. other than that it runs fine.
@Aviator14 That might work as long as you could hold the mower down or atatch it somehow to the jack so it can't move
Thanks. Just wondering how I could pimp it up abit lol. Change tags or more?
Alot of times bent crank damages seal and needs to be replaced
Very ture
nice video you need to pimp it better so you can get more views. thats a rather nice push mower
Thanks, just got lucky

Had nothing to lose
@BriggsMower This ones still runing good, and I fixed it in 2009
There has to be Angels looking out for Farmers.
Some of the things I've seen done to keep stuff running are pretty scary.

that was in 2009? for 8 years? lol
I've gotta do this on the exact same model of lawnmower
I'm going to open it up and replace the crankshaft
Outstanding video! Do you repair watches as well?
@Moosepiesandwich shaft is too long and too small.
@madisonelectronic Thanks for the info
You done fixed it? Well I'll be damned. Scooter told me it couldn't be fixed. 'Course Scooter is about as shiftless as one poor son of a bitch can be. You done fixed it. I'll just be damned.
@workensmart 40 to 50 dollars? what planet are u from?
Not bad pal!!
@fixinggrace I had nothing to lose at all lol.
I got a yardman lawn mower I had her 2 year nail I was mowing the other day and hit a tree stump and bent the crank and the blade is bent two and she is leaking oil down throw the crank what do you think I could of done two her.
@Keister12 Hahaha thanks bro
I hit a rock and created a hole near the screw kinda like yours but smaller, is this gonna create any problems?
Prob, I got lucky with this one. Not sure if its still running or not. Been a few years now
@brewzur Sweet
How much is a new crankshaft? Somehow shattered mine when went I've old tree stump
WARNING THE CRANK IS NOT TO STRAIGHTENED REPLACE IT YOU ARE SETTING YOUR SELF UP TO BE SUED. IF ANYBODY WANTS TO CHECK IF THE CRANK TAKE A MEASUREMENT FROM THE SIDE OF THE DECK TO THE TIP OF BLADE ROTATE AND CHECKING THE OTHER SIDE OF THE TIP TO THE SAME POINT ON THE DECK DUHH!!!!
Thanks!!
I hit a wet sock mines hard to start nd shakes hard is my shaft bent???
Wow.....
You were lucky you got it perfect, a little off could be noisy.
Thanks
dial indicator!!! lol!!😃
Getting oil in cylinder I think making noise cause laying on side
If it cracked when you tried this, it is worth considering that it may have cracked on intial impact with the blade obstruction.
It might not last but its better then it was lol. the one I did still going
My dad taught me as a young boy if I ever see hammer marks on an engine it was worked on by a Fool~!!! I had to stop watching when I saw you bring out that large sledge hammer.
A common misconception is that cranks are brittle.Not true.They are intentionally soft,so they will bend instead of break off.
hit it another time
The cranks on those engines must be made of very low strength iron.
sounds like shes done if its leaking oil
And I say hillbilly as a term of endearment because of the title of your video not to be mean or rude
You need to remove the blade hillbilly that way you can hit it back straight all you're doing is making it worse
This is exactly how NOT to fix a bent shaft. You can do further damage to the engine by hitting with a hammer. I would personally not trust this guy with my mower.
Mower was junk as we are not a loud to straighten shafts that way anymore. It's still running today
You said "A customer dropped this off."
It's not junk
They don't make small engines like they used to.
Your blade isUPDIDE-DOWN !
u no t a red nek
The main hazard I see here is the force you are applying is being carried into the motor casing and you run the risk of damaging the case and/or the bearings. if you could put a block of wood between the engine and the applied blow with that block bearing against the ground, you would take out the applied load and transmit it to the ground. That may require dismounting the engine from the deck.
Best place for your kid is next to a mower that you have been beating on the blade and shaft with a hammer. Father of the year.
