Attempting a repair my mower to get it ready for the mowing season. Thanks for the help
The diode makes half wave dc voltage. More than enough to charge a battery. The battery does not care how unfiltered the dc is it just cares that it is dc. Remember the fly wheel and it's magnets create ac at the tap so you need the diode to rectify it to dc. Just thought you wanted to know. Great video and nice puller for those types of situations.
Just the same as on my Ariens 2000 rider and got the same problem. Just need the gear puller and alternator with diode. Thanks so much!
Glad it helped
I use a steering wheel puller, so all the force is on the crank shaft, I also use a impact air tool, but best idea is to spray pb blaster on the crank shaft to clean up the area between the shaft, and the flywheel..... Not an easy job, you did great.
good tip! thanks friend
Love your videos. They're very helpful. You don't edit out mistakes or the times when Murphy's Law kicks in and things don't go as planned. Happens to me ALL the time. Thanks.
I appreciate that! Thanks for watching
Man this guy is destructive.
holy shit right
Thank you! The bash the socket wrench with a mallet trick just helped me get the nut off my one. No other video I could find had this tip.
Your humour throughout this is right up there with bill but !!
That's a good way to wreck a ratchet wrench. The cheap ones often have plastic parts inside.
10:48 2 get a flywheel off I just take a pry bar and put some pressure on it and and hit it with a hammer it comes right off
After a hour or so yeah that way does work
pulling flywheels are like pulling ball joints.You never want to put that much pressure on the puller .After u have your puller set up tighten it up then hit as close as u can to the center of the flywheel with an air hammer .This method is the easiest best method to remove all types of flywheels .Ive pulled100s of flywheels like that
great tip!
After tightening puller to put strain on flywheel, apply heat to flywheel hub until it pops off shaft.
My biggest laugh all week , whacking the flywheel nut lololol...
Great video.
I got a 84 LTV/10 identical to yours. My alternator is a full circle with points and condenser underneath having a similar issue to you.
Have you done a part 2 to this video? Thanks for the video! I just subscribed!
not exactly but I do have other videos with this mower here is one ua-cam.com/video/4NsBvCXKvwk/v-deo.html
Can also remove spark plug feed in some nylon rope into the spark plug hole to jam up the piston. It keeps the motor from spinning. After you loosen or tighten the bolt just remove the nylon rope.
yes but I am always worried about bending a rod doing that
@@JeffsLittleEngineService I think bending a rod is impossible when using the rope method on any engine, because I think they are much stronger than the grip of the fastener... unlike the chance of bending relatively fragile open valves on any 4 stroke engine if the rope is not inserted in the particular stroke to have them closed which is either before the top of the compression stroke or after the top of the power stroke depending on whether removing or installing the fastener. Make sense?
@@JeffsLittleEngineService You so damn Funny 🤣😂
Just hanging hard
A tip for those having trouble holding the flywheel still. A pipe wrench or pair of vise grips clamped onto the drive pulley underneath and resting against the frame/axle as a blocker.
But I already took the pulley off, and I was bending and breaking stuff trying to hold the sucker still just trying to remove the nut. Then I dug out the almighty air impact wrench, Bob's your uncle it zips the nut off with EASE without holding the flywheel. And then I stuck the flatbar underneath the flywheel and used the convenient dimple in the center of crankshaft for the air hammer that I also dug out.
Just wish I had enough sense to do that before I broke a couple teeth on the flywheel :/ hope it won't cause starting issues, but at least everything's loosened for the next _go round_ if I need to replace.
The old rope down the cylinder through the spark plug hole , then turn the shaft till it tightens works good to stop the shaft from turning
that always makes me nervous.....
Strap wrench works good holding the fly wheel still
Good tip, That is the best way I think
Crazy little engine Jeff lol
This is why you should never let a anything with a small engine set outside.
Jerome Cook some people don’t have a choice
Much love for manual impacts for where they shine (ancient motorcycles which have JIS case screws...) but a light electric impact is far better for jobs where you DON'T want to bash the part you're removing. If you already own a harmonic balancer or steering wheel puller the good ones are much stronger than the cast Briggs/AYP/whatever part and Grade 8 bolts are cheap.
a steering wheel puller works as well
isn't there a flywheel lock item for doing this?
And a short bunji chord to pull that cable out of your way?
Obviously he’s no millwright 🙈
grate video Jeff
your impact driver has a square end under the attachment cap you can use on sockets.
Thank"s for this not a lot out there about this specially for us comon folks w/o all the fancy tools just working on the ground. 👍
@@MrMackAtack I do all my work on the ground, layout two or three sheets of 3/4" plywood, a piece or two of carpet to save on my knees....L grew up on horse farms and made friends with a guy that turned out to be a self-taught mechanical genius back in the 70's-80's; went to Industrial Systems Tech college in 2000, been working on things as a kid without knowing from a single parent home, everyone that worked on our car I would be in their pits if not in school. Tried to learn anything I could from anyone that knew how to do something by watching them, then practicing.
If the module was ok couldnt u have just soldered on a new diode to the wire (with correct polarity) & using correct type of diode?,do u know what type diode is?
That is absolutely NOT the only way to get the flywheel off.. There are several ways to get them off.. Easiest way is an air hammer or a pry bar an hammer..
Southern Bucks it’s way faster and easier
@@ezraducat4826 What are you Talkin about ?? SOUTHERN BUCKS ??
Did you ever consider liquid wrench penetrating oil ??????
good tip! I should use it more often.. however, my patience in letting it soak is always difficult!
Very helpful
Glad it helped
Myself, I would have laid 3 five sixteenth nuts on the screwheads and mig -welded down thru the centers .(OR.... Use a sharp chisel to cut the center out of the screen to access the nut. )
Or you can pry up on flywheel and wack the bolt with a hammer. works like a charm
Ol skool... Good tip!
Hey there is another way to pull fly wheels. Just put a pry bar underneath the flywheel and with the nit flush on crankshaft, smack the nut with some force and it will come right off
The Silkys at 12:35 were my favorite part!
A little off topic but I recently had a crack in my flywheel but it's a newer style flywheel with no fins. Is it possible to rig an older flywheel on?
not sure
😂 that's what I feel like doing to my lawnmower whack it with a sledge hammer 🔨
It does make you feel better sometimes
What happens when flywheel is stuck so bad and pulls the bolts on the puller into?
If you can hit the nut or bolt that holds the flywheel down with a 3lb. or so sledge hammer (or are able to use a "knock-off" tool) you may be able to shock the rust loose if you know what I mean. Of course always be careful not to hit or damage the flywheel
I have done that with one puller while the flywheel was under tension by hitting the puller bolt, I have the genuine B and S puller that I used a heavy punch thru the center hole and under max tension any more tension and I am parting the puller bolts I have ordered some grade 8 bolts for the puller to try IF the puller will stand it thanks for the reply

why not use an Impact wrench?
Good tip! I did not have one available at the time.
@@JeffsLittleEngineService you,r welcome thanks for Sharing
u could heated the screws loll, or WD40 i like that brutal, hahaha great job loll
do you ever clean the parts
Nope
You sure showed us how to bruise up the engine!
It can be rough and tumble around here sometimes my friend LOL!
brutal,absolutely brutal.
JESSUS lol but have to AGREE THEY ALL NEED THAT lol GIVE IT TO IT HA like my old UNCLE use to say if you cant get it off with that USE A BIGGER HAMMER! ha !!
Put a pipe wrench on the shaft under the deck..
You got downright medieval on that.
Thank you
I was just going to say you could have used 1 of those flat crow bars to hold the fly wheel in place while get'g the bolt off and gently use the crow bar to pop the flywheel off.I just watched this in another video.I am lookg for a video on how to use a wheel puller.In another video the guy broke his wheel peeler cuz instead of doing it the old fashioned way with a ratchett he used an impact tool.
I lost the flywheel nut on a 5 hp Briggs and Stratton motor on a old Craftsman tiller it is not a 5/8 too large and not a 1/2 inch too small do you know what size it could be or where I can buy one?
I think it is a unique nut sold through Briggs and Stratton only. Let me know if you find a common one that will work
Thanks I will keep look looking I just bought one from a man that repairs lawn mowers he took it off a junk lawn mower and it fit. It is out of stock in all the places I checked and it is some bastard size to rip off people by B&S. I will let you know if I find some common part!
good news!
thats the size wrench or socket it takes, not the size of nut. for example a half in bolt takes a 3/4 wrench.
I fell asleep watching this.
importance of wearing gloves - i was following this yesterday- removing the flywheel - two broken fingers and a bruised thumb - felt good .
That whole stator looks shot and fried from old age.
My stator wire goes from that to the rectifier then to the ignition relay from that to the battery
the ignition solenoid to the ignition relay to the battery. I disconnected all safety buttons on each riding mower.
Damn guy, don’t make me laugh any more!!! My ribs hurt!!
shoulda just cut a flat line into the heads of the screws and used a flat head screw driver
I agree. It was nails on a chalk board watching him pound on the head of his engine. Im sure that was good for it
I done that a ton of times
Or vice grips...
Try using a pry bar and a hammer
It was a good comedy watch
You can Tell Amateur all the way ... 1 Do not be hitting gas Tank or frame, Take a Longer wrench ........... 2) Secure the Fly wheel, below Engine by putting, a wood stop, or Vise grip by the bottom . instead of Flywheel Fins,which will break . 3) get that Cable out of the way to work on it ...
I tried using a clutch / steering wheel puller it tore through the puller ...
yikes,
Dude take the bolt or nut off that holds the flywheel completely off if its a nut screw it back on the crank shaft level with the shaft or screw the bolt in a little put A big screwdriver under flywheel pull up hit bolt with hammer. Dont need the flywheel tool
Disassemble it with dynamite ... maybe do it before
😂 don’t take got mower to this guy.
You can clearly look at the coil an tell it is not a points type ignition...
Luckily you didn’t blow yourself up with the sparks going all over the fuel tank!!
Why not remove the end of the impact driver which exposed a 1/2 inch drive and put your socket on it
How bout the half of the stator that's missing wow
The half circle stator is normal for a machine with no lights.
Use a small Dremel tool
everything looked a little smoked on that mower, including the chickens
920 tap the top center w/your hammer
good way to loose a finger if that wheel would have grabbed with your hand in the way like that ud be a digit down
Is there something wrong with this video or is it me. ?
Spit screen why?
should not be split screen
Jesus!! LOL I never seen anyone do this type dangerus FIX LOL
Lol! Living on the edge
Don't force it, just get a bigger hammer.
beware of the ratchet method for taking off the flywheel bolt...you have to know the rotation of your engine if you turn the engine backwards you could cause problems
I turn them backwards all the time
I get that yet it is not a practice to teach when working on any engine...complicated or simple..was researching doing a timing belt on an 02 focus it was said dont turn the engine backwards...to sum up what Im saying know your engine if you do decide to rotate it backwards not everyone is experienced as you are.
@@settripsbunch My understanding in certain timing setups, the belt or chain can lose tension when the engine is being turned backwards, causing it to skip time or otherwise hang up inside the timing train. The Briggs motors that I've torn apart all have a gear driven camshaft, and should not be susceptible to this problem. Just my 2 cents.
I do not see how the hell a puller works on some of these Motors. You get a steering wheel puller just too find you need too pre drill the holes in the flywheel too get the puller too fit. Hammer, and pry bar, with some trans fluid and acetone mixed. Let
it soak a bit at the shaft, and beat the hell out of it. OK, tap it a bit.
How sad is it that this video has +200k views😢
Have you considered a penetrating oil liquid wrench.
We know you put that impact on the flywheel nut.
lol!
that one looks smoked....... and that one looks smoked lol
My 11 year old son fix iwere ridding mower
I got a Solution......
Get a brand new Lawn mower tractor 🤣😂
but then I would have nothing to fix...
@@JeffsLittleEngineService Just kidding man....
Sometimes..... We have to joke around....... In today's World is too much Stresses and issues Everywhere.... And Lazy people are everywhere too
Omg what is this guy doing lol
That nut should've been 15/16". That's what every birggs I've worked on was.
you are probably right!
15 Sixteenths is the WRENCH size, and OLD engines with rope cups are left hand threads.
You sound like Jack Nicholson.
Please buy another Mower.
I am sure glad u don't work on my mower -- shade tree- frick and frack
lol!
what is that? a MOTOR or a ENGINE !,also,, a ALTERNADOR or a GENERATOR?
jose tavares Good questions... an engine is a gas powered component. a motor is an electrical component. Both alternator and generator generate electricity they just do it differently. In an alternater system the magnets rotate and the copper coil is fixed in place. It is just the opposite In a generator, the magents are fixed and the copper coil rotates.
jose, it's an alternator
This was painful to watch. Hammers and cheater bars are not,.. never mind.
would not drop off any
If you got this far, what harm is a couple of purple Herman's on your hands ? 🤬
❤❤❤😘😘🥰🥰💋💋💋💋💋💋💋
There is no excuse for breaking fins
If you watch others you’ll learn alot
sometimes the plastic is so brittle from overheating the fins break just when you look at them.
It's not brain surgery
These nuts 🤣🤣🤣🤣🤣🤣
Pretty handy
If your know how to....What's that !
English Mik!
..I think this video was meant to be a joke.
yep
A normal screwdriver would have probably worked
poor workman ship,,
it's only a lawnmower ... not a Ferrari
Sorry but not a good video for a DIY situation. Need to be more direct and accurate in your presentation to leave a feeling of you know what you are doing for those wanting to follow your direction.
Thanks for the tips!
My God Jeff, I Cringed When You Was Hitting The Ratchet And Slipped, Nearly Taking Out The Air Cleaner. Not Good Practice To Do That Sort of thing To Remove The Nut. I Had To Close My Eyes When You Put That Extension Bar In Between The Flywheel Fins and Torqued Down On The Puller Nut. I Thought For Sure You Would Break The Fin Off. Another No No. Some One Has Been In There Before and Broken Half Of It Off and Put It Back Together Like That. That Is Supposed To Be a Complete Round Alternator . You Only Had Half Of It There. If You Broke The Fins On The Flywheel It Can Become Unstable and Also Not Cool The Engine Properly. Be Careful Folks Not To Do This. ( BAD Practice )
good tips!
That’s not how you use that tool.
This is how not to do it. He simply could have snipped an opening for his socket. Bend the sharp edges down. Hammers in my opinion do not belong in a mechanic's tool box. They always lead to problems. P.S. Always turn an engine clock-wise. Never Never counter clockwise. A strap wrench or lg screw driver against the gear teeth to prevent turning to remove the bolt. Duh!
Why do you say to only turn the engine clockwise? My 3lb. lump hammer is my favorite tool.
That was the most amateurish effort I have ever watched. Bloody embarrassing.
talk is cheap. post videos
butcher!!!!!!!!!!!!
You'll never make many sales. Your presentation is to lenghty and bs
I thought I was replaying to a ad about fixing my aching knees . Sorry for the comment above. Apoligize.
