I've always noticed that the guys on RUclips like you're self only have half a million subscribers but yet you're videos are always the best always to the point never clickbait and never beg for subs and advertise super expensive merch, people like you still give RUclips hope thank you for your service ❤️
Yeah you are right, you definitly sound like a yt OG ^^ Mustie is one of favorites youtubers for the same reason
well said. mustie is pretty dope.
No annoying intro with music, no boring intro "hi this is me" talking head mode, but instead immediately shows us the machine and the issue. That is so refreshing
I agree with you 100%!
It is unfortunate that the world is filled with entirely too many people that thrive on and/or are addicted to sensationism.
Him and Andrew camarata are my favorites. They should each have 5M subscribers.
Water and oil do mix. I was our plant's oiler. We had 4 presses with approximately 3 thousand gallon hydraulic reservoirs. When I took over in 07, the oil looked like dirty milk. I talked the management into buying a purifier/dehydrator. With a small 10 gal/min unit, it took 6 weeks to clear the oil. I caught over 200 gallons of water that was condensing in the exhaust port. Before I got the purifier, we were going through 1 or 2 high pressure pumps every week. They cost $5k each, the rebuild kit was $3800. After purifing we went a year and four months before we lost a pump, and it was probably half worn out to begin with. Water and dust coursing through the pumps had worn the orficies and internal turns at least twice the size that they began life. Later we got a 50 gal/min purifier, and an 80 gal/min filter cart. New virgin oil came in in 275 gal totes, and were filtered to 50 microns, (you can see a 65 micron particle with your bare eye), so I filtered to 3 micron, and that oil would sparkle. We went almost 10 years before loosing a pump. They operate at 3000 psi.
Ahh….Sunday wouldn’t be the same, morning Mustie….👍🇮🇲
Somehow, I'm willing to invest 30 minutes of my life finding out how a worthless piece of junk across the country became worthless.
Sir, you are a showman!
Well, as I see it there's a lot of free parts from this machine. Not everything is broken.
Given the condition of the machine, he should have bought a new connecting rod. All that damage to the crank journal is superficial and it's not in the crank, it's aluminum from the rod. It would clean right up. The crank journals are hardened. All that surface problem is not in the crank journal.
@@facel2 I doubt those parts are "more than the thing is worth", new ones (518 ZE Snow Blower) are listed at $589.00, so a repaired one he might sell at half price and at the least, it's good to give machines a second life and keep them out of the landfill. It has a 99cc engine too so he could either buy new parts or used off ebay. I'm surprised it costs that much new because it sure looks like a small budget model.
@@facel2 The only part you would have to replace is the rod and cap. The crank is fine, it just needs to be cleaned. None of what you can see on the crank journal is actually material from the crank. It is bearing and aluminum material from the rod/cap/bearings. It will come right off with a very weak acid.
Plus, Mustie1 is special. Mustie could EASILY make 10 thousand dollars on the video. He probably is making North of 25 grand a month. He has a half a million subs and his videos get 10s of thousands of views.
For Mustie1, it would be "worth it" to even buy brand new crank and rod and piston. Really, replacing every single part on the machine would be "worth it" because the end product is a youtube video, not a low end snowblower. IMHO, I think it is more interesting to watch it be repaired than torn down and made into a parts pile.
@@facel2 1) That failure was not that violent. There is no damage to anything else.
2) You are making an economics argument that makes zero sense given the end product is a youtube video.All his major costs are FIXED. The marginal cost of a video is very low.
3) Most things people do are not "economically viable" anyway. 60-% of people (or more, that's a low end) are losing money to do any kind of repair on anything
Repairing almost anything makes no sense from an economic point of view even if the parts are FREE. Most people earn far more money on an hourly basis than they can save fixing something.
If it is worth fixing at all, it is almost always more economically viable to have someone else do it. It will take them FAR longer than someone with the right tools and knowledge than it will take the average person. If you're a lawyer fixing a lawnmower, you are throwing away money. A hobby is the ONLY justification for fixing this stuff.
Now, if you're a small engine repair person or even an auto mechanic, not so much.
Part of me was surprised Mustie didn't dig into the hoard and com up with a connecting rod and make this thing at least fire over. I know, not worth the effort but I have seen him work some absolute magic in the past.
I was hoping he would . This thing could be saved . But as a parts unit ,it’s perfect.
Or another engine entirely, he has one a little like it I'm sure, and he's going to cuss himself when he comes across it in his hoard after the rest of the machine has gone to the junk yard. I love Mustie, he's a great guy, I've watched his videos since 2008 or so, he knows what he's doing, and he has all the tools a guy could want.
I was really hoping for that scenario as well.Then i saw that Jeep thinking it was his at first..all these teasers.
My thoughts exactly. I was certain he was going to resurrect it
Sure, but these things are junk even when new
Mustie going over to a friends house... "You got anything that doesn't work?"
after so many of your awesome cool video's , im sure you can fix my mother-n-law, she wont start doing anything, and she sits around leaking gas, and taking up space in the garage, cool video thx for uploading
Sounds like she’s run out of lubricant. Your regular spill and fill job, I reckon. Might want to look out for a possible plugged exhaust also
LOL
Even though these older models are pre computerisation, they can still suffer from a simple ID10T error
I just wanted to finally thank you for what you do with your videos I am a veteran who is now disabled, so most days I am confined to my chair and a lot of TV. I am a former mechanic of sorts, and I still have learned so much from you. Love your videos, keep them coming!.
You know what I like about this video, is ALL that clean aluminum for scrap!
That engine was run without oil in it. The rod over heated from friction and it welded itself to the rod as the engine was running. The flywheel weight kept the crank spinning and it bent the aluminum rod untill it broke, and the crank hammerd what was left of the rod until pieces were everywhere. If you take a look at the crank journal you will see that it's covered in aluminum. Believe it or not that is probably repairable. The aluminum has a lower melting temp. than the steel crank so you may be able to manually remove the aluminum from it. The bearing surface may still be ok. If that's the case a new rod and a careful component inspection and it should be servicable once the valve issue is addressed. The valve is stuck because it was submerged in water. It's most likely not bent because it got rusted stuck after the crank shaft broke while sitting in the basement or where ever it was. I would soak it in Liguid Wrench for a day or so then try tapping the valve out of the valve guide carefully. If you meet resistance shoot some more penetrating oil in there and try it again the next day. When you do get some movement spin the valve some and it will begin to free up. Once you get the valve out put it in the lathe and clean up the rust and put a mic on it to see if it's bent. If it's not, clean up the valve guide with a brass rifle bore cleaning brush and a drill with more Liquid Wrench. Now clean the seat and drop the valve back in.. Check the piston for damage, free up the rings and clean the ring grooves, get a new rod and wrist pin and reassemble. Give it a try. I have done this at least 10 times. It should make a good video too.
It’s not worth it. parts horde
@@EZ4U2Say11 It would be worth it to someone who had the same problem but only 50 bucks to fix it. It would be worth it if it got a million views too.
A trick for taking aluminum off of crank bearings: hydrochloric acid (aka muriatic). You can get this stuff from hardware stores - used to etch concrete, and for some REALLY stubborn hard water deposits in toilets, rust stains etc. CLR (and similar products such as Zep acid toilet cleaner) are effectively the same, but not nearly as strong.
Put the crank shaft horizontally above a plastic pan in a well ventilated area. Cut strips of paper towel the width of the journal surface. Now put on rubber gloves, safety eyewear (and double check your ventilation). Dip a strip or two in the acid, and carefully evenly wrap the soaking strips around the journal. Wait about 10 minutes, remove the paper towel and dispose safely, and wash/clean the journal. You'll notice that the aluminum is disappearing. Repeat as necessary to get most of the aluminum off. Since you're doing it quickly, the HCl doesn't have time to damage the hardened steel of the crank. Finish off with some fine emory strips which will remove the last aluminum and polish the journal.
This will *usually* not make the journal too small - mike it if you have the correct info. In some cases you can get piston rods in slightly different sizes (much the same as oversize pistons). Good as new.
James Condon has showed this technique many times in his videos (usually those involving blowed-up generator motors).
@@fromagefrizzbizz9377 I've never tried that method however it sounds to me Iike it has merit. Most of the time honestly though the bulk flakes right off with just a pick or carefully with a screwdriver.
I will try this next time to see which is easier or faster. Thanks for the tip.
@@TractorWrangler01 It depends on how bad the deposition of aluminum is. The HCl trick is the best way to preserve the original journal surface as best as possible, without risk of scratching it. When done optimally, the aluminum is gone, especially the smaller hard-to-pick bits and just needs a bit of polishing.
Let us know how you did. I do recommend watching one of James Condon's videos showing how it's done.
This was probably used to clean the snow off a pond for skating, and went through the ice. Hopefully, the operator had enough sense to let go.
Possible, but hydro lock is instant. This one had to have been running a while to make that big end of the rod look like that.
That said, I’m sure there is more than one lake around the north with a snowblower sitting at the bottom.😂
Exactly what I think. It had to be running and went swimming to break the rod.
I Wounder if it had breakin oil? And was never changed.
excellent theory
Exactly
I love these autopsy videos. Those are the videos where heads come off, and engines get completely pulled apart (as opposed to ordinary carb cleaning). And it's always neat seeing how these things grenade themselves.
I had a friend that bought a brand new gas powered air compressor and he did add the oil to the compressor but assumed the engine had oil in it when it didn't. On tear down the Briggs looked pretty much like that and yes he put oil in it after at blew up too.
Thanks for having me over bud good to see you
As always - thank you for your time and effort. I am not an engine guy, and have no clue. Because of your videos, I am getting a better understanding of how things work.
Very easy to get into small engines, give it a go. Most of the broken stuff at the curb just won't start and/or has bad gas in it, as you will find is the case with 99% of the stuff Mustie hauls home (in other words, they have spark and compression but the carburetor is clogged). And with plenty of "fix it" videos on YT, you can basically watch and become an expert on one particular engine. The rest of your time is looking up parts numbers and shopping.
@@Hjerte_Verke Thank you for the great advice... I'll have to start looking to get my hands a little bit dirtier... LOL - have a great night.
A military Jeep with seven grill slots? The fender configuration also looks newer than 1953. Ah, yes. The old Jeep interchangeability can of worms. Good luck. Too bad about the snow blower. I own a similar unit. I change the oil, change the paddles, and change the belt. So far, so good.
Always great seeing your video on the notification.Thanks for sharing and taking us along
Hey mustie,,I am addicted to picking up these damn mowers on the side of the road,,today I got another one ,30 minute later she's running like a new one ,,all thanks to the mustie one
FINALLY I get to watch a video. I don't watch when they are over an hour long.
I have a theory, someone bought it, threw gas in and ran it. Not long after it started knocking due to no oil, so they add oil in a useless attempt to save it but it let go. The water could be a few things, flooded basement, ice dammed and snow melt ran back into it. I think even you would be amazed at how many items come into my shop that never got oil or a 2 stroke ran on straight gas
The Manual Says No Internal Parts Available,So what you Have is A Parts Unit For the Hord,I had one come to me with the adjustment valve mechanism stripped so I used a heli coil and fixed it.
That thing look salvageable. New rod (cheap on the internet) polish the rood and hone the cylinder. Good to go
I had a 53 M38 I put a 67 327 Vette motor in it and it could lift the front wheels when you popped the clutch!
A new piston and rod; and she's good to go! Get this thing running!
Ouch! They knew by the sound it made to just drag it to the curb. lol Great video!!! :)
Everytime I watch your videos, it's like I'm hanging out in the shop with an old pal, Thanks!
A machine that even Mustie couldn't save. At least, he has parts to save other machines. Thank you, Darrin, for showing us this.
"It was running when it rolled down the hill and into the pond." That's what I expected to hear!
Dr Mustie, great detective work
Mustie1 talks the talk; more importantly he does the actual work. I wish I had him as a neighbor. Keep up the great work.
When you mentioned the posibility of someone running with no oil, reminded me of a vibrator plate I bought. User manual states "Ships without oil, fill according to engine manual" . . it didn't come with engine manual to tell me how much to add (or confirm where).. Much searching I find their tiller used same engine, and THAT manual said to add however much oil it needs.
Went to add oil, glad I added carefully, as it was shipped with oil in it.....
Sometimes the manufacturers don't help us "mere mortal" owners look after the stuff.
I'm so glad you stopped using a screwdriver and got out the hone! I want to see it work again!
I just saw the crank, never mind!
"Hey! Laser Lips! Your mumma was a Snow Blower!"
Haha I couldn't resist!
Sorry XD
I find the dismantling portion of these videos very satisfying and relaxing. Of course, if one was to put everything back together again, I wouldn’t remember where anything went….lol
A quick and dirty autopsy, I love it 😀
Those small snow blowers are really handy.....They dont take up much garage or shed space and can be pretty mean on a smaller drive or walkway. OMG. I used one in Toronto and was totally impressed.
There is so much new opportunity for America to have a Renaissance resurgence in manufacturing. Surprised no teeth were missing on the plastic gears. Good nylon/poly.
You must have the parts in your stash I say let's get it running. Here's 👍👍 for getting the snowblower running.
The good engine doctor has successfully completed another autopsy.
That Jeep was real nice
15 minutes in, here's my guess: It was left in a basement, as you said, the basement got flooded, water got into the crankcase. Then the owner tried to start it to see if it still runs, it probably did start up, but then because of all the water in the crankcase it hydro locked the piston from behind. I bet that the bent valve that doesn't quite work is an exhaust valve. Piston was on its way down after ignition, connecting rod gave out, and the exhaust valve slammed into the top of the piston, pushing it in the position you found it in.
I had governor failure like he talked about but external windvane type, but mine survived just because the carburetor was small enough to keep it from self destructing before I could shut it down and fix it. Dirty air filter might have helped.
I can't agree with immersion/hydraulic failure scenario. Too much scoring of the crankshaft throw. Extended downhill run till failure imo... possible low oil level..
@@kendonahve924 Well, when I wrote that we weren't that far in with the tear down.
I got up early and had to wait a bit. It's always worth the wait.
I agree 👍
That's a nice Willys at the end there. I used to take mine to the show in Weare.
SUNDAY is fun day with Mustie 1 .
love the old jeep.
Maybe someone used it to clean off a pond for Hockey and went through the ice.
Sunday 1PM (local time), Musti1 time.
That M38A1 is a cool project. We're rebuilding one on our channel as we speak. Sadly our video's are in Dutch so kinda hard for you English native speakers.
@luc an Marco's Garage after reading your comment I was curious and checked out your channel to my surprise closed captioning has auto generated subtitles in English.
Cool I will check out more on your channel cheers from Ontario Canada
@@barrymcbride thanks for your comment Barry. Did not know that it subtitled our videos. Hope you had fun watching our video's.
Sweet Jeep. Would love to see that running again.
Mustie you could probably clean the bearing journal with Muriatic acid to remove the aluminum and save the crank. toss another rod and piston on and you got a winner!
Done that a couple of times…..
The tilt of the cylinder in the snow blower engine makes me believe it would make a good candidate for a DIY moped project.
Great video glad you posted keep them coming thanks
Guess will never know what killed it!! Thanks for sharing!
I had 2 of these come in last winter for repair with the same problem. Broken crank. My assumption was that the plastic gear on the cam spun throwing the timing off while in use and the valves came in contact with the piston and snapped the rod. With the damage on the piston, id say the same for this one.
@dan the mower medic. But that doesn't explain the spun bearing, the connecting rod big end was welded to the crank journal. I say it was a lubrication issue
@@dannyjamison8337 No bearing to spin. This simply looks like it ran out of oil and self-destructed. Then, they put some oil in it and realized then it was junk. Stowed in low area and filled with water.
The marks on the piston on this one was caused by the screw driver he had in the plug hole. My guess due to these being rather cheap snow blowers is there wasn't enough oil clearance between rod and crank and it tore itself apart. Manufacturing defect.
With the way you save things, I thought you would have saved the wheels. Have good days!
Don’t think it flooded in a basement, there is no rust or tide marks on the outside of the machine!!
Still enjoy your vids, thanks Mustie.
Sunday morning with mustie brilliant, that must have gone with a bang , spare parts for days, 😂🤣👍
Excellent video Mustie 1 :) also you did check out what happened and excellent to find too ! I enjoy to!
All you need is for someone to give the same model with a broken snowblower and a good engine😁👍
Couldn’t believe it, but this unit sells for $800 new at the orange box! Worth fixing? About $100 for new piston and rod parts. Another $90 for a crank if you can’t clean up the old one. Need some gaskets and a lot of time restoring that head. Probably worth fixing for someone who wanted to use it. Fixing for resale would be a crap shoot, at best. Then again, good luck buying a snow blower this winter with supply chain issues. I ordered a Honda from my local dealer in April to be ready for this winter. That got me on the “maybe” list!
Hi Mustie from west Alabama ty for your show
Thanks for taking the time to diagnose the failure Mustie1!
Very educational dissection.
Thanks for the autopsy . It was a lot of fun .
I'm amazed with that shotgunned rod, those plastic gears are still intact.
It ain't junk for Mustie1! it's bunch of reserve parts for his future projects 😂
need to say love your videos thanks
I would bet with the right-sized VW engine installed, that thing would be a snow-throwing beast.
those big box store toro's were POS out of the box. lucky they managed to clear light fluffy powder snow maybe 3 inches deep
Add a 36 hp!!!! Lol
Lots of good parts to get from it such as pulleys, belt, switch, recoil starter so not a complete loss, just add it all to the stash.
I sure like that 38A M1 😁👍👏 I saw the tire at sek. 08 upper left corner and was waiting to see the story behind it? Thx. 😉
Great Diagnosis.
Thank you Dr. Mustie for allowing us to observe the autopsy
Loved the autopsy!!
It would be nice to see the Jeep when it's up and running again! Patrick Tipton is your Jeep guru ("Portrayal Press" channel).
Snowblower..... Hmm, could be that it was run low on oil, bound up on the big-end and tore it out, someone added oil after the fact (the Bugnaration Factor) and then left for a while gathering dust. Following that, it could have brought out with a view to fix it, or maybe sell it, and the owner pressure washed it, forcing water into the exhaust, and up into the cylinder via the open valve - especially if the job was entrusted to the kids! They'd love squirting water into a little hole and see it disappear.
It doesn't look like it was under water, it's too clean, there's no rust to speak of, and no precipitated dirt on any part of it. On top of that, there are no tell-tale tide marks to Indicate the levels as the water rose and fell.
First ever water cooled snowblower in history?
I read somewhere that snowblowers get the most engine damage when people jam if into a snow bank, the engine goes full throttle and then they push way down on the handle while it's wide open and starve the conrod for oil which might have been low to begin with.
Unless the oil dipper breaks the rod won't starve for oil.
Keep in mind that many walk behind mowers die at WOT in tall grass.
@@BeingMe23 It'll starve if it's low on oil as they often are and as Í stated.
Like to see the jeep running 👍
GREAT VIDEO, SEE YOU NEXT WEEK...
Enjoyed the autopsy 👍
I loved this video. It took me back to my Power Mechanics class in high school 40 years ago. Thanks Mustie as always!
I have this same model, I’ve used it the past 2 or 3 winters; my Dad had it before that. Needs a carb cleaning every so often but the electric start is a big relief on my arm. It’s lightweight and easily maneuverable, I can easily lift onto & off my elevated front porch to clear it. I can almost dance with it. It clears my 100-ft driveway with no issues. It’s the only gas-powered tool I have; everything else is either corded or battery electric. I hope mine has a better run than this one did; I can’t tell if it’s the same engine.
Great New England accent in your friends voice.
Good Morning
A lot of people buy this stuff and assume the break-in oil is in the crankcase but due to shipping regulations, none of these small engines ship with oil in them. Many stores will add the oil or inform the customer about the need for oil but that isn't always the case. I would guess that they added the initial oil and it ran low over one or more seasons since the oil looked a bit dirty and the oil line looked very low on the dipstick. They never added to it or changed the oil and then it blew up and they parked it either in a basement or near the edge of a roof and rainwater was allowed to run off onto the unit or it was flooded and they went and bought a new one and then this one was hauled out for junk pickup.
Well now you have a bunch of parts to add to your horde. 👍.
She is toast, off to the parts bin with this one. 🇦🇺🇦🇺👍👍
adding Oil is always optional, if throwing money away is your favorite pass-time. 🤣🙃
seeing all the water in the engine, maybe in a flash flood? or deep basement flood from failed sump pump. I've seen basements filled to the 1st floor rafters in the past.
Workin on any small motor is instructive. Thanks do more and what to save off the trashed blo
Jack Klugman would have been proud. Cheers
That's what you get with a Chinese Honda! They should be called hit and miss engines. Sometimes they last for ever, or not.
Also, good example as to why you should always store your small engines on the compression stroke. Keeping the valves closed will help keep water/moisture out of the cyl.
aaaaa! I saw that jeep and my heart skipped a bit 😆
Love to see you getting your hands on that. You are the best thanks 😊
Only time oil and water mixes is if there is no air present, at least I seen videos on that mixing in vacuum chamber, glad you are doing well mustie.
I keep seeing the little green boat motor under the bench and wonder 🤔 when will you get back to working on it and what you will find to put it in, but as always, excellent job on the find and video.
Nice to have a short video once and a while. Great content! Now lets get back on that red car!
Short or longer, Sunday morning with him is a must !
@@marcryvon You forgot the “ie” on must!😜
You’re just easy to watch! Your knowledge comes second. Thanks for the movie length entertaining tutorials.
Good one, Mustie. Short and sweet.
I so love your videos. I've been tinkering around with engines and classic cars here in the UK for decades and am just about to rebuild a B&S 4hp motor from my garden rotorvator.
Sunday morning, coffee and Mustie. PERFECT
👍 Nice little bike engine. Enjoyed watching, Take Care!
My guess for water intrusion is they pressure washed it at the end of the season.
I believe you hit it on the nail with the water breach into the engine with a pressure washer.
Now we see how you get all the stuff in your stash.
Thank you for sharing, Enjoyed.
I have the two stroke version of this. more often than not, it never makes it further than the side of the garage for our two week summer. Downspouts get clogged with oak blossoms and whirlgigs in the spring and overflows right onto the lawnmowers and snow blowers 😉👍
