- I got this old yanmar military air compressor for only $200. I thought this would be easy to get running but it wasn’t long til we found out the fuel system was gonna need major overhaul, we fixed the fuel system only to find a plethora of more problems.

“Prolly not gonna be good for it.” Gold. Great content.
Nice, a nother pice of equipment saved. I would recommend adding a quality fuse on the positive wire of the battery as close to the battery terminal as possible and insulating caps on the battery terminals and other exposed positive connections. Keep up the great work!
Thank you. That was my plan but I got in a hurry
Excellent build. Great compressor. Recommend reinstalling a safety guard between the pulleys/belt.
Luv your channel! Makes an old man's day just go better!
Good to hear 👍
10/10. I don't know you or what you typically do. What I can say is that you found an item, found the problems, and fixed those problems. You had the brain power to come up with solutions. You have what it takes to do anything that needs a mechanical mindset. Keep it up. I noticed some other interesting things in the background. I'll stick around.
This is too much fun for one person. Thanks for sharing
I love the channel I’ve gotten a lot of inspiration from you and it has helped me fix several pieces of equipment so thank ypu
I've seen that several times young man. That's what happens when some cheapo runs their equipment on French fry grease. It does work but only for so long. That's why it smells like dirty fryer. JP8 is mostly kerosene and never does that. Don't listen to these armchair pros, keep doing what you are doing that's how you learn.
It runs ok depending on the type of veg oil, temperature or if it's blended. The real problem is you can't store it with veg oil in the lines. I've been running biodiesel in just about all the diesel equipment on the farm, but anything that get parked for a while gets off-road run through it before.
That looked like a lot of compressor oil. You will see it has a sight glass at the bottom of the case, which is currently dirty. It should be half way up that sight glass. Just if you were not aware. Too much oil in a compressor can do real damage, as the arm is slapping into the oil every rotation and slings it around. Too high and you can do damage.
Hi a question
have you considered starting an engine and then cleaning or refurbishing after testing if it works or not , because after cleaning it might not work as it might damage some parts
My boy got some skills,really impressed!
Thank you for sharing, always a pleasure watch your project, your explanation are awesome 👍👍👍👍
Great job with this one!
Jet fuel basically is a refined version of diesel. paraffin, diesel, heating oil & Jet fuel are all heavy fuel oils.
Only JP8 doesn't have the lubricity of diesel and will ruin finicky injection pumps. Stanadyne pumps on HMMWVs bit the dust pretty frequently down range on jet fuel
great work not sure how i feel about putting the drain plug in with a impact though
That's all pretty slick, man. Got yourself decent little compressor. That's cool.
keep the videos coming dude cause they're very entertaining great channel
The 2 caps on fuel tank the big one is so can be filled from a fuel truck small one is to fill from a fuel can I would repair the frame and add angel irion to beef it up
Top Job ! 👍 Keep them builds coming.
At first I thought it was bad editing to leave in the "it just got dark" stuff, but then I saw it got really dark really fast and I realized it was worth seeing.
I have a theory that someone tried to run this engine on asphalt. My second theory is that heat soaked into the fuel pump and broke down some junk oil they were running it on until it all plugged with tar.
Great save , put water proof cover over electrics and switch , a little water from rain will wreck the switch, not hard to straighten alloy frame and reinforce with steel angle .😊
You did a better job than an AF Power Pro shop😂
Braden has shown me how to diagnose problems easily
Your channel is awesome enjoy watching
Good job Fixing thatdiesel motor You got a Bobcat out there what size is that I got one just like it mind at 444 Bobcat I took the motor out of mine and put A Vanguard 23 Horse So have a good day stay safe and we'll see you again my friend
I have not watched the whole video yet but the charging system on this engine series usually produces about 30volts ac witch has to go into a voltage regulator to convert it to 12volts dc
I'm wondering if you should use a starter solenoid instead of running the battery directly to the start switch? The switch may not last long, if it's directly connected to the starter. Just a thought. Great find a work getting it back in shape. Wish I could come across deals like this!
@@stevesweb there is a solenoid on the starter
@@BradenBuildz Sorry, I missed it when you showed what all you did to the unit. That thing should last forever. Keep up the good videos!
@@stevesweb another military one soon
Did you drain the oil from the air compressor too? Great video though!
@@WallyBecker-x6m I did shortly after I made the video. I also flushed it out. It was nasty.
It is totally fine to push the decompression lever while running to stop it
That electric fuel shutoff solenoid looks identical to the one on some 5.9 Cummins industrial engines with the rotary pump. From Cummins, they are well over $100. Amazon has them for about $35. Been there, done that. Lol
Ultra sonic cleaner on all the fuel system
That compressor probably sat around for a long time with old fuel in it. Then, some newbie private was told by a senior enlisted to fill it with anything flammable.
Not enough of the 4 legged mechanic in this video, but I still approve!❤
Neat. At present day, a battery tire inflation device would be the more common method......... but an "in the field" air compressor could be put to many uses
@@DeadKoby this is more so for larger trucks. In the past I’ve had to use a large electric wall plug in compressor paired with a large generator. Now I have it all in one. But most flat tires can be had with my 12v compressor.
From Subie owner to Subie owner: Get that rust under control as soon an possible! Or elese you have to probabbly send it off to get a whole new rear end (had to do so on mine...) But nice video as always!
Thanks. I actually bought this car as a fun beater. Paid $1400 for it and I’m not worried if it rots to the ground lol. The rust is here to stay.
Google's auto captions think the torch sound is music 😂
lol XD
I would say that black goopy stuff was the reason it was auctioned off in the first place. They probably just wanted rid of it because it wouldn't start
The lever isn't just a kill lever it's the fuel rack. Without that, you can't regulate speed.
They can run on JP8 jet fuel but it is not good for the engine sometimes it was all they had when they were over in foreign countries so they would mix some ATF in with the fuel for some extra lubrication
That thing would be great in the apocalypse. Since it's a small diesel engine you could run just about anything through it such as offroad diesel, vegetable oil, olive oil, used motor oil, peanut oil, heating oil, kerosene etc. Heck the oils would possibly even be better for the injector pump than diesel fuel since modern diesel fuel doesn't have as many lubricants in it since just about every modern diesel powered vehicle these days doesn't have mechanical injectors and just has electronic injectors.
7:01 me when the taco bell employee asks me if my food looks good. 🤣
Good job bringing it back to life
The original injection pump may be fine, you got to remember that the plunger is being compressed and then released every time that the engine makes a full 4-stroke cycle, the fuel metering lever on the side of the pump might move freely when the plunger on the pump is extended?
@@69uremum problem is, it doesn’t move when it’s bolted in it’s spot. At all, at any time. New one does
@@BradenBuildz gotcha, makes sense.
@@BradenBuildz I have a Lister diesel powered generator, basically the same working principle as the engine you have in regards to the injection pump. Diesel generators are better than a gas equivalent in my opinion.
I don't think that was the shut off, i think that was the throttle control. seems like rpm is a little high. Hey, you do good work!
Bro at 31:55 was like no risk no fun😂
Awesome machine mate and great video :) Such a shame you pressure washed it though, you destroyed all the original powder coat :/
Thanks, and it’s not powder coat, it’s called carc paint. And if it comes off with a pressure washer. It’s already in bad shape.
I've had the tar looking sludge in the fuel lines on a old lawnmower before. It was hard to clean it all out
Why not try and straighten the frame?
good fix
The mechanical shut off was working correctly the engine has to be spinning for it to reset, there is a spring in the shutoff that moves it over once it’s on its depression stroke
New one doesn’t act like the old ones. Shut off lever moves weather it’s compressed or not.
Tested the new one in the vice just as I tested the green one.
The after market injection pumps are pretty popular because of this.
Braden, the lever on the side of the injection pump isn't a digital device (on or off). It is an analog device, controlled by the fly weight governor inside the engine, giving speed from off to rated speed. It's a good thing you got it freed up, otherwise, being stuck in thee full fuel position, you would have had a runaway engine. :( Granted you could have killed it with the compression release lever.
No, it’s on/off, none said it was digital.
The lever quite literally says “start/run” and “stop”
Edit: and also you can tighten lever to hold it in place. If it was a governor it would not allow you to do that.
@@BradenBuildz This is wrong. It is an adjustable governor. You set the desired engine RPM (all the way to 0 which is "stop") by using the nub, then the governor inside the engine keeps that RPM (up to a point, if you exceed the maximum load for a given RPM the engine will still slow down and possibly stall).
They are widely used on all of these little diesel engines and usually the full open position keeps the engine at 3000RPM. If it wasn't a governor your engine speed would be much faster when the tank is empty and the compressor has no load, but you can hear that it runs at the same speed all the time.
It is not supposed to be stuck however. Now that the engine has been run a while I bet it has freed up.
It's not really that bad, just clean everything. If the IP is clogged then u have a problem.
Jet fuel and diesel are just light oils, that's oil diesel in the pump ir just straight oil.
YOU shouldn't have a hard time finding an injection pump for it. all
Well done son... very good... most would've given up on that ol gal. I suppose you forced it back into service - non-military...
I have seen jet fuel turn into that sort of black tar/sludge and it's a pain to deal with
It actually looks like the battery box.. Is for a motorcycle battery..
Why did you set the wheel on fire
He drives a subaru, it's all down him from here.
Looks like Cosmoline!
My first thoughts too!
It has to caps because of different size nozzles
just to put it out there idel seems very high from sounds of it all most sounds like its trying to run away
JP4 and JP8 ( jet propellent ) is much like diesel fuel , a more refined kerosene product .
When jet fuel gets old it turns into that tar like substance, explains why you found it throughout the fuel system.
Where are you from?
That Tar substance is probably the buildup of JP-8 fuel used by the Military. JP-8 was specified in 1990 by the U.S. government as a replacement for government diesel fueled vehicles.
that's a harbor freight compressor head... prolly a rotax diesil... that green says its came from vietnam era... that tar would be jp-8 bunker fuel byproducts
Not from Vietnam era, not a harbor freight compressor and it’s a yanmar diesel.
Jp-8 is an id for jet fuel
You can shut the engine down with the compression release
@@patrickharris2807 right. i just wanted something fancier
@BradenBuildz I got you. The injector with the full shut off is pretty sweet. Good work bro.
You did a really good clean job fixing this up man
Shutting down the engine with the compression release is absolutely not recommended. You would be squirting fuel and incomplete combustion byproducts back into your air filter through the open intake valve, dirtying it much faster than normal.
That tar is bad jet fuel. I'm sure you figured that put though lol. Kind of like varnished gasoline, but infinitely worse.
i think that tar thingy is the pipe overheated and melted
Sweeeet. Love watching.
nice job.
Never put a drain plug in with a impact
Your “always” auto corrected to “never”. That’s Wierd🤔
I'm guessing that tar is 50-year-old diesel fuel. Definitely convert this to a genny.
Diesel fuel is great for cleaning that old tar sludge
damn good save
Enjoyed the hole video !😅😂🎉
that tar is probably really old JP-8 fuel
Very nice work
Jet fuel is just a grade of kerosene. Loads of old engines used it.
The black something that you are looking at is a coding that they put in the gas tanks back in the day isn't got old because of that old gas in deteriorated
I'd like to recommend you wear nitrile gloves and work in plenty of fresh air. Lots of guys don't heed that and spend their 50s plagued with health problems or they straight up croak. I've seen it happen plenty. It's not worth being lazy or macho thinking you don't need to protect yourself.
Def need to wear gloves more. It’s just hard to
I don't think the bent frame fix was the best way to go. Rebuild and restoration is to restore as close to original.
This isn’t a restoration page
If you ever get tare fuel like that all you need is a lighter or a small butane torch to heat it up and it will melt the junk out if it
the sticky jell is old diesel! stuff is a pain
This was great.. Thanks.
it would be best to straighten and tighten the frame
Just set them in some diesel fuel it will definitely save that injection pump or paint thinner gasoline etc wonder why someone would get rid of it
The military order job specific tools and then sell them off once the job is complete, which is a huge waste of money. But it's not their money they're spending though.
You should get yourself a ultrasonic cleaner would be useful to deal with the parts covered In tar
I have an engine very similar to that
"TAKES JET FUEL"
Or, in other words, it runs on KEROSENE.
Kerosene based jet fuel. Just like gasoline is petroleum based.
I think You should leave off the hand starter but change it for a grate- better cooling that way. I´d leave it off when the starter/charger do their job. The Military just wanted to be shure it goes.
And I´d advise to always wear gloves and open the shop before starting anything or start outside. Any engine farts out its worst when it´s cold, the 1st thirty seconds are the worst. You´re a young buck, I´d like for You to turn into an old fart, not die after ten years of suffer with sixty. And while we´re at it: try start the bugger at idle, let it build some heat and oil pressure- then give it the beans.
You´ll become old together- job done.
Kind regards
No throttle control. Only on/off
Jet fuel is parrafin, kerosene, central heating oil call it what you like!
Awesome
Water in the intake has gotta be healthy for it 5:45
Now that’s what happens when jet fuel sits around for a long time
Well todays a good day!!
What about the air filter?😂😂😂😂 what kind of mechanic are you mate?😂😂😂😂😂😂
Maybe someone sabotaged the engine by pouring sugar into it. That could explain the tar.
That tar is what happens to old jet fuel.
They get rid of stuff 50 years old still in the crate brand new
