- Briggs and Stratton engine strip down and rebuild time lapse. This is the narrated version of how to rebuild a mower engine. This lawnmower engine rebuild is a 4 horsepower Briggs and Stratton built on the 2nd February 2001
Engine Code: 010202
This is part one of an engine rebuild short series. In this lawnmower engine rebuild video we are tearing down the mower, inspecting and checking for any damage and then I will rebuild it again in the next part of this engine rebuild short series.
Job well done. I've torn hundreds of these engines apart and am sitting well for spare parts. How they go together again, who the hell knows.
Wow, raining outside, rebuilding an engine with a couple cold ones. Best day EVER!
I just ordered a gasket set for a Briggs flathead I’ve got on a mower I picked off side of road. Engine runs great but excited to practice disassembling, measuring crankshaft journal for wear and reassembling. Had a chance to practice lapping the valves and removing about 2 thou off the exhaust valve stem too which was fun!
Channel like a politician... promise and never deliver...
Legend has it that that rain came so hard and so fast that part 2 was filmed, but it lays at the bottom of river in a GoPro in an unknown English town.
Right next to the rebuilt engine....
Excellent! Thanks for being fast- paced and explaining with your voice!
Good job and no BS. The video showed me what I need to know
Part 2 is brilliant.
But where is it tho
Very good video it's straight to the point very educational I have been wondering for years how to remove the Piston from the style lawn mower now I know and I think I will rering one of my mowers now :-)
Thanks, I disassembled a quattro like this to clean it and then waited and waited for a new head gasket to arrive, foolishly thinking reassembly should be a doddle - ended up with the two flywheel guards hanging around and wasn't able to figure out how they re-attached! A slow-mo of this let me see the position and fixings - thanks!
have the motor torn down in my shop now I'm waiting on part 2 please and thank you
I watched this video so I could work out how to get the piston out (the rings are busted). The engine fits the description perfectly so I should be able to do it no problem!
That engine is a dead giveaway because of the air filter on it. They had both metal and later plastic ones that are both the same shape. But I can't get over the size of the muffler and huge heat guard on this thing. Here in Australia I ended up with a cheaper US version of this engine with like a tuna tin sized muffler.
Excellent video. And for those asking for part two, there's really no need for it. Just reassemble in the reverse of the tear down.
My mower still in pieces because there is no part 2. My grass is so high I can’t leave my house 😢
Anthony Rendon LOL
😂😂😂😂
Weedwhack your way outta there little buddy! You can do it!
We’re here for ya! 😂😂
🤣😂🤣😭
? esrever ni ti gniyalp deirt uoy evah - have you tried playing it in reverse ?
Thanks, now I know that the little pipe going to the carb is a breather
The rain didn’t bother me, G. I wouldn’t have noticed it, or ignored it if I had. I need to take a minute before I start to get ready. Take care.
Excellent video
Thanks! cool to see a tear down like this!
Cheers, just bought a mountfield with a Briggs and Stratton which I’m not sure works. This video will be useful to me when I get to work
I could only find a thumbs up button? Where's the 'love the guy for putting this vid up!' button?
Thank you for the video. It helped me so much.
The crank can be straightened. Use a dial indicator to check it. Bolt the engine down and use a piece for pipe for leverage.
Thanks for filming this!!! VERY illuminating. I always wondered what was inside a lawnmower engine!!! :)!!! :D!!!
settle down
Wonder no more. Get better deal not requiring a rebuild. I gave away a lawnmower with a bent shaft - before I became a DYI WEEKEND WARRIOR LAWNMOWER FIXER..
WHO HAS TIME OR BRAINS FOR ALL THIS? I shoulda kept my 30 year old Tecumseh with bent shaft. C'mon., I don't have time nor brains for all this rebuild stuff. Good video though.

What a great video. I have a very smokey 3.5hp unit. I believe a ring job is needed but after watching this that looks to be a piece of cake. Probably harder to ascertain the engine model number for correct parts.
I’ve never rebuilt one of these. In your case, would it be easier to just buy a new piston already loaded with the rings? Serious question.
Rebuilding a Briggs & Stratton motor from 1960 and it's literally EXACTLY the same. Lol.
Oh good cos I need to rebuild my 700 series 190cc platinum and I hope it's the same.
I cracked the crankcase sump a bit along it's short inlet shaft using the old trick. Will use cold weld steel reinforced epoxy JB Weld to repair it. Hopefully it holds.
i love these little engines
Great video, thanks!!
Was looking for part 2. Then I realize you haven't been here for 4 years. Hope you are alright. Cheers
I bent the crankshaft on my lawnmower. No need to strip it down. I hit mine with a lumphammer and straightened it.
My favorite weapon...err TOOL!! I got the Swiss Army version, it does a multitude of tasks. Funny, it looks just like a regular hammer... Handy man's second secret weapon, right after DUCT TAPE!! Thanks Red Green!!👍👍😎
after watching 45 seconds i liked the vid as this is exactley what i am doing i have 2 bent crankshafts i can fix one but not the other as i need to buy another crankshaft
Great Video! Thanks for sharing!
Crazy, how does the plastic cam gear survive being in that engine??
Quite. At least it's not OHC so not a potential catastrophe.
Amazing info while video is on. Love it. Awesome. Well done. So much info as most vids are quiet and have to figure it out
Cliffhanger ending to a series.
🤦
good job
Great information. Is there a part #2 showing assembly and how to check components for specification?
Would imagine B&S makes a rebuild kit for their engine models?
The most important part ; pulling the flywheel. Knobend.
Cool vid mate cheers
Can you straighten the crank using a press? Also, My edger smokes bad for a few seconds if I roll it to its side. Do you think it needs rings or new piston and rings? Can you oversize the bore just using a hone? Thanks for the video.
Please do episode 2
Paul from Australia. Can anyone tell me where I can find part 2 please?
wheres part two dude
There's no part two? My mower is in pieces, my lawns are getting long, and my wife is getting mad. What do I do?!
Michael Frank Improvise. Adapt. Overcome. Or just buy a new lawn mower, whichever is easier
I was just looking for part 2 myself. Just play this in reverse
@@MichaelFrankNZ wow you're so good at copying the top comment how witty and original!
@@Salsajaman thanks mate. 🥰
how did you remove the hub that joins onto the crankshaft? the one that holds the blade plate on? regards
I subscribed so i can learn some knowledge thank you for the video.
Where's part 2?
That’s an interesting way to pronounce carburetor lol. Good job nonetheless
I can't find part 2 of the rebuilding. Is there one?
Where’s part two, the rebuild?
What does the "breather cover" actually do?
Where's part 2 man.I'm trying to replace Governor in mine.When I pulled in apart the Governor just fell out.This video is so fast I can't see him pulling it out?
Could someone help me..trying to find different video.
the problem is putting it back together. by the time i get the part i need, i forget what goes where and what screws and bolts if i can find them.
where to buy the piston connecting rod and gears....???
That was awesome
I can not find part 2.
what bends a crank shaft to a lawn mower?
Is this daggerwin?
Great instructional video. Many thanks for posting as my B&S engine gives out a disturbing loud tap (knock) when throttling up and or starting suggesting big end bearing / conrod. What are your thought please if you don’t mind. I assume there are no bearing shells as in a vehicle engine?
Thanks again for sharing. Regards.
Long live the 2 stroke....
Steve Q it’s a 4 stroke Flathead Briggs.
what price do you sell rebuild lawn mowers for or were can you get a rough price list
Fk I miss shop classes in high school.
It’s a pity you didn’t show were the crank shaft was bent , I couldn’t see anything in the video that showed a bent crank shaft .
I can rebuild these and 2 stroke engine but i can never keep track of bolts and where they were removed from or where they go back in and always end up loosing few.
Do you have a part 2 video? Part one was helpful, but now need help putting it back together! Thanks!
Simple, just watch it in reverse.
What size nut is the flywheel nut?
When it comes to valve jobs, let a shop do the valve job. You need special tools which are expensive.
Great video! I have a similar engine from a techumesh lawn mower. I'm thinking of running the cylinder vertical for go-kart engine, so the drive shaft is horizontal. If I do this how can I ensure the oil will reach the crack shaft unless I fill the crankcase full to the brim with oil?
Attach some sheet metal etc to the bottom of the counterweights when they are at the bottom of the stroke. The oil will be flicked upwards.
No part 2?
Where is part 2
So I have a question I was taking the side cover off my 3.5 craftsman lawn more and when I did a piece of plastic fill out that with a little metal rod with a ball at the end of it I can’t figure out where goes ?
bummer no part2
Hold on just a minute! 1:07 the bolts to the oil filler tube are already out. I've tried every socket in my toolbox, and nothing fits. Even tried adjustable wrenches, mole grips, and slip joint pliers. Nothing budges these bolts.
Please... what size are they, and how did you get them off? I'm guessing you had the same problem and that's why the video is clipped just before this point?
Edit: Ignore that. I've just watched another video, and I don't need to unscrew these bolts. The filler tube lifts out (pulls up) along with the starter coil. Only an issue if the filler tube itself is broken.
Every time I spin the throttle, the back wheel won't move, what should I do?
It Daggerwin.✌️
my other half over filled the lawnmower engine and looks like exhaust valve seal is gone blowing oil into the exhaust anyway I xan do the seal with out breaking the engincase
man, you need a drill with a bit for sockets. Ratchets are so slow.
Hello! What's your opinion, can this engine works if it will stands vertically? I have one b&s 375 and i want to build motorized bicycle using it. I don't sure what piston will be lubricated well.
when he says carburater and magneto
Will you go over cam shaft timing when time comes to putting it back together?
I took my 6.5hp engine apart without thinking of timing.
You align the dots on the gears. I always noticed that when the timing is correct when the valves rock, one closes when the other opens, the piston is on top dead center.
Any ideas for an extremely stuck crank case sump? We tried lubricant and a gear puller, pounding, wedging, all sorts of stuff but it will not slide off the shaft.
+retrotellephone Have you removed all the bolts?
+Ed West Is this a joke?
question
just got a new briggs block
15c107
do i need to hone the new cylinder ?
The assembly of the lawn mower could be done without any problems czcams.com/users/postUgkxTPN04aT-Qdjr_KS3ql7ng8wnU3wwsCqk also recommend I just puzzled something about the red strange “key”. However, it quickly turned out that this creates a kind of contact bridge between battery packs and lawn mowers. An additional backup as a father of a 1 year old nephew is great!! :-)
I've written down all your steps carefully so that I can take apart the two Briggs & Stratton engines I've got outside that need rebuilding, but I can't seem to find where your rebuild video is. Is it not up yet? Thanks so much!
Hi, no it's not up yet I am hoping it will be up soon.
Sweet! I'm having some trouble getting my flywheel nut loose. Would a lubricant like WD-40 be okay to use on it?
Yes, that is fine.
+GardenMechanic is that you Daggerwin
+GardenMechanic i blew my 6250 generator because low oil .Is it worth ordering a new engine or buying a new one
I have acquired one of these for free and was wondering if I can use it vertically if I put a different carb or try to rotate the original, I'm thinking with more oil in the case the crank will splash oil inside to keep everything well lubed.What do you think?
I dont know what engine you got, but i'd recomed modifying the engine first, because the Problem wont be fixt by ovetfilling the engine when the fuel and oil lines are facing the wrong direction and the engine Starts to run dry
There's not even a part 2 to this!
What happened to part 2?
hi my mower is starting but just chugging not revving I have cleaned the carb and diapham /gasket new spark plug new petrol any tips would very helpful many thanks ste
+steven fitton Buy a new mower
Buy a less labour intensive repair model or buy new.
Get a 3/8” ratchet bud, how do you work with that clunky 1/2” ratchet? I’d lose my mind.
Anyone know where I can get a list of torque specs?
Part 2?
Is this dDaggerwin?
or the crank bushing might be worn out
❤❤❤❤❤❤❤❤
This is what I really hate , when there is a part missing.
So disappointing a great video , but now we are stuck waiting 6 years.
Pointless.
paul meynell just reverse the process lol
is there a part 2
I am rebuilding a toro lawn mower that has a bring and Stratton engine and it is burning oil. I already have it torn down to the crankshaft please tell what I should do to fix the oil burning problem?
Joe Dirt Piston rings is your problem but might aswell replace the piston and connecting rod and the oil scraper rings
Toss it! Seriously! For your average Briggs,I don't fool with them any more because its cheaper to replace it with another lawn mower from a pawn shop. Just remember to take care of the maintenance next time.
Your pistion rings are bad that's one of the reasons why it burns oil
Joe Dirt replace the rings
Does this small engine have a way to adjust the valves?
carl cappy you can file the plastic piece inside
gm it is a 3.5hp briggs
They are hard to tell between because the 3.5 and 4hp look identical..This one is called the Quattro 40 even though it looks the same as the 3.5hp Classic...I guess it could be either.
Thanks for commenting!
What is the crank shaft responsible for in the engine?
DaPopeFrancis716 Virtually everything
DaPopeFrancis716 it converts reciprocating motion from the piston into rotational motion.
It pushes the piston up and down, thus being responsible for the 2 or 4 stroke cycle.
That is a stupid question!
It's where the Hamsters live
