Quick tip for loading a grease gun; When you are pulling the plunger out of the cartridge, crack the bleeder/ unscrew the tube. You are creating a vacuum inside the gun, that will suck the outlet empty. When reloading, screw the tube 75% up, push the plunger up, then finish screwing the tube up. You just bled most of the system in 5 seconds
You can also "hydroform" thin aluminum with a grease gun. Create a steel fixture with a solid bottom and a steel ring to clamp the aluminum down. Pump the grease between the aluminum and solid steel slug and makes a nice dome shape. Could also make interesting shapes or lettering depending on your upper form of the fixture. Would love to see aVe do a video of this.
That's funny that you posted this, a few days ago at work I needed to widen a hole in some sheet metal to pull some wiring through. I tried to use a hole saw but with no center point it just walked all over the place. Our maintenance guy saw me and said he had a better idea. He came back with something that looked like a grease gun with a threaded hydraulic cylinder on the end. It was a hydraulic sheet metal punch. He just put the punch end on it and started pumping and it retracted the cylinder until it punched out the hole and it made me think about what kind of pressures were in a normal grease gun. Now I know!
It's not the destination, it's the journey that's valuable. Use it as a learning experience on how to think. AvE is a goddamn Canadadian mechanical genius
In small excavators they actually use a grease gun with grease in it to activate a hydraulic/grease cylinder in order to put tension on the tracks. Easy and very effective
Work in aircraft daily greasing, it’s quite helpful to know that the pump element above the cartridge goes to around 1700psi. Many components are rated so we don’t blow bearings and such etc. 1700psi per 5 white knuckles!
got a tip for ya, when changing a cartridge unscrew the tube from the pump 1 full turn to release the vacuum created while trying to pull the plunger back..... and hey at least its a Lincoln gun.
You are sooo funny in your narration. You are truly informative too. I worked with a guy like you. Those were good times. Broke me up when you asked" Why you no come?". I laughed out loudly. My wife looked at me very strangely.
I machined an adapter for m14x1.25 thread. I fill a frozen motorcycle cylinder a pepetrating oil, then thread the adapter into the spark plug hole. Then pump up the cylinder with the grease gun to force the oil past the stuck piston, and to force the stuck piston down. It works like a charm!
It makes me so happy to see new vijayos coming up on my feed. I can't realistically have much of a hobby shop in my apartment; living vicariously through you is just as good as it gets!
During the contact dermatitis speech I was waiting for the personal lubricant joke... Obviously your teleprompter wasn't working during that bit and you were just winging it and forgot.
@AvE Just wanna thank you kindly for making these videos. You've given me hours of entertainment. Also i have had contact dermatitis from a combo of lime juice and the sun (lime burn)after pruning the trees, Its terrible. Gotta start wearing gloves in the shop, id hate to get it from working on stuff.
Old bottle jack: Weld the shaft to the body so it can't move and tap a fitting to the pressure gallery. Now you have whatever PSI the jack was rated at...
its amazing how just a bit of grease can give you that much. At work we sharpen side cutter headd for a huge mfg. company and that is how we tighten them on the arbor and how the run the heads on the machine. Its really awesome. Thanks for showing actually showing how it works
+rustyheaders Damned loyalists and their square screws. I used to work for a division of a company based out of Montreal at an office in the US. They did all the ordering up in Canada so every feckin' thing we got was covered every square inch with Made in Canada Maple Leaf stickers and Robertson screws. Why didn't they just combine their efforts and engrave the Maple Leaf around the perimeter of the Robertson screw? Fortunately some items had universal head screws that would accept Robertson or Phillips.
Worked as a sparky in maintenance department for 50 years. Just about every hydraulic system that I came across leaked hydraulic fluid. Even 2 new Green lee hydraulic hand pumps for knocking out holes in panels leaked before they were a year old. Back hack that I ever seen was when one of our mechanics left a deposit in other mechanics cliffs cup. Guy got the portable bread pump on the heaviest grease that was in a 30 gallon grease drum. He installed a few zero fittings and filled the guy mechanics steel tool chest up with the very thick grease. By the time he was done entire box was filled with grease. Took the other guy at least 6 hours to remove grease from inside box and tools.
I'm well aware of the pressure these grease guns can generate. The wheel bearings on my saw are protected by 1/8" thick steel hub caps which are sealed to keep the crud out. After a few years of occasionally greasing them, I noticed I was having a hard time and when looking saw I was doming the flat steel cap out with just the pressure of the grease inside lol.
@@Leroys_Stuff Humm I'm not in that job anymore, but i don't think they were made like that? They had a hard plastic seal, IIRC, not something of pliant rubber that might have worked like that? But it's been a long time since I saw them, quit that job like 3,5 years ago. The messiest side wasn't relying on the bearing seal anyway, that was the purpose of the cap, to keep the muck from even touching the hub in the first place, on the side that faced the blade.
Im having a problem where my better half is getting mad because im using chooch and skookim too much in every day conversation and she says you're a bad influence. any advice?
........ "Propensity for homoeroticism". Hahahahahaha! I did a double take on that one. I didn't get the reference during the first watch. The depth of your humour knows no bounds.
@@BillyBoze No such thing. Place I worked at before I retired we went through five industrial guns a month. Boss quit buying the "cheap" ones and we succeeded in going through only *four* per month.
@@soconoha We used them mostly on plastics extruders. The zerks tended to get gummed up because they ran at about 430 Frankensteins even using very expensive high-temp grease plus as I said management bought the cheapest guns they could find. Maintenance had a hard time keeping up with the zerks.
In the gas patch of Colorado we use modified grease guns filled with methanol or antifreeze to force ice plugs from the process pressure measurement tubing on our gas compressors, they will build over 5,000psi even with such low viscosity fluids as these the trick is you have to pump them faster as the tolerances on the pump are such that the fluid will just bypass the pump faster than it can be forced out of the gun. The lever style guns are what we use so you can put more force on it
3000 PSI hydraulic pressure is about as dangerous as a fluffy kitten with the amount of flow a grease gun can provide. I used to deal with 6000 PSI nitrogen every day, all the force of hydraulics with all the energy storage of pneumatics. With 8 big ole high pressure gas tanks for capacitance, there was enough energy to ruin your day in a big hurry!
Love these videos. They're both highly comedic and educational (if you have learned how to decipher AvE English to Standard English, Haha). But seriously, I enjoy watching them. Keep it up, thanks!
1700psi?! Sturdy little machine for something that manages to leak from grease separation any time it sits more than a week. As far as a lack of built-in valves goes, the typical grease gun is designed to deliver its gooey payload to fittings with built-in check valves. I don't believe it depends on viscosity to prevent back-flow. Anyways, thanks for the vid!
Gas lines use single 45* flare fittings; those types have thinner walls which break easier under pressure. Automotive brake lines, however, use double 45* flare fittings. Those things take well past 5,000 PSI and it's the brake caliper or pads that fail before the fitting goes. Best part about all of them is that the flares automatically seal, no teflon tape required.
This may be old hat to most, but I saw a guy at a gravel pit use a grease gun to tighten the treads on a dozer.. That sounds stupid, but there is a cylinder between the cogs for that purpose.
Hey buddy I’m appreciating to be a millwrong in Saskatchewan and your videos have given me tricks. P. S the Milwaukee grease gun hasn’t let us down yet. And I use that mofo every morning
They do come in handy for removing pilot bearings! I've hammered away with slide hammers for far too long, when I should have blown it out with a grease gun. powerful little things they are!
nice video. I think I will have to start wearing gloves. You mentioned about contact dermatitis. For decades I've never worn gloves because they take the feeling of dexterity away. So I have been washing my hands frequently.
+George W I work with a lot of dirty stuff in the repair shop. I prefer these gloves granberg.no/ENG/products/list_multilang.aspx?cat=2&sub=4 , They are a tight fit and keeps your dexterity very well.
I used a grease gun to free up a puck froze tight in a disc brake caliper. Snapped right on the bleeder. A bit of a mess when she left go, but worked slicker than snot.
I have used a grease gun to pump out stuck/seized disc brake caliper pistons when compressed air won't budge them. Just plug the brake line port and use the bleeder valve as the inlet port. Funucking believable.
we call those fittings #6 to boss (o-ring side) in the gulf of mexico. trick in a pinch if you grind the bevel off the #6 it will thread in to the cylinder. that is a good Stanley hydraulic tools trick.
A dowty washer is what I think you meant when you said about face sealing that fitting to the cylinder. I use them all the time on hydraulic test rigs.
Grease guns also make a handy pump for hydro-testing pressure tanks. But that also involves the nightmare with fittings problem that you illustrated here. As usual, the setup takes ten times longer than the actual task.
Grease guns don't need a check valve because grease fittings have the check valve built in. It's the small BB looking ball in the end which has a spring behind it
That kPa is the nice old metric SI-unit for pressure. 1 Pascal = 1[N/m2], so one Pascal is basically nothing. There's roughly 6.9[kPa] per 1[psi], or 100[kPa] per 1[bar] (or 14,5[bar]/1[psi]). And then 1[MPa] is 1[N/mm2], and the mega Pascal is what's normally used for tensile strength and things like that (yield strength of a typical mild steel maybe starts out somewhere around 240[MPa], which then roughly translates to 24[kg/mm2]). Once you learn the correct SI-units and the basics of the metric system things are quite easy.
Fun fact: Destructive testing of hydraulic components is often done with high pressure grease pumps. It's much more efficient to pump grease to 10,000-20,000psi than it is to pump oil to that pressure. In fact, I thought that's were he was going with this demonstration.
+Maxwelhse My dad used to work in the wireline industry. He said companies used to send them free tools to try to get their business. They had an old gun barrel from a Navy ship that they sunk down into concrete and would throw the free sample tools down inside it and pressurize it 20,000psi and leave it for a week or so, and then retrieve the mangled and crushed tools and mail them back with a note that they didn't last long enough.
stonent What was the practical application of the "machine" they built? That seems to be an odd construction that must have had a specialized use. The testing I was involved in was for hose reels and we were pressurizing the components internally, not externally. Primarily deep sea equipment and safety reels ("jaw of life" reels were certified to 10,000psi, for instance).
The grease gun that you used here was only made for general purpose greasing not high pressure. If you get one of the ones with the long handle on them and not just the little grip handle, I believe they are double the pressure. Still an interesting video though, cheers!
speaking of the pneumatics. I was working on Press 76 A 2500 ton Danly stamping press. We were stamping Torque converter bowls for Generous Motors. 8 die stations in the press. All the draw plates in the dies use nitrogen die springs. Lloyd the die maker is working on one dies. He emptied the die springs to lower the draw plate. Time comes to refill them he puts the QD connector on the inlet. Bob the foreman is standing over Lloyd the Die makers shoulder like there is some part of this job that requires the skills of a man knowledgeable in the use of a clipboard. Lloyd the die maker goes over to the cart with the Nitrogen bottle on it. Bob the foreman stays where he is. Lloyd the Die maker opens the valve on the bottle. When the Draw plates rise back up with a clank the QD fitting fails. 15 feet of high pressure hose and a brass QD fitting are whipping around the floor. Bob the Foreman is hopping around trying to get out of the way, He gets tagged 4 times in the legs and ass before Lloyd manages to shut the gas off.
This is about all we're gonna get out of this little guy. . . . he says. Wow, not only was it impressive to see how much pressure you achieved but I was surprised at how fast it got there. When you consider how long it takes an air compressor to hit 150 psi, I'd have thought anything past 500 would be pretty slow going.
that's because this is a non-compressible fluid unlike air, so you're not wasting nearly as much energy heating up the fluid or compressing it. it's just a translation of where the force is applied.
if you take apart the fitting where the grease gun hooks up to the zerk fitting you will find a check valve in it ( the little bit at the end of the hose from the grease gun you removed)
some off the old Lincolns say 10,000 psi on the handle. I think 7,500 today. even the battery one ($400). with grease. that's actually the pump you tightening tracks on heavy equipment with.
Hey AvE, another great vid: funny and informative. Question: how do you bleed the pressure off of your system? Just unscrew one of the fittings? Would you end up wearing half of that ATF you pumped in there? I can actually think of a couple good uses for something like this and may build something bases on this concept so I'm curious about the bleed-off.
Used to work with large jackhammer cylinders and those used on the back of skip trucks anyhoo was involved in a catastrophic failure narrowly being missed by the piston whilst my workmate wasn't so lucky and was sent across t he workshop as the side of the cylinder ruptured during a test. Our health a safety concourse employers didn't see fit to fit a screen of ballistic plastic so the poor guy took the full jet across his ribs. He wasn't badly hurt but did pass out and was taken to hospital and was leaking hydraulic fluid from the impact sight on his ribs for a couple of days.
How about a bottle jack for something like this? Wouldn't that cut out a lot of the extra parts you need here? Great videos, love them. Keep up the good work.
Really nice video but Hydra Mac has used Alemite 500 with hydraulic oil to lift the top cover on their Commander 4200 skid steer I think year 1998. I didn't see check valve in line that could be the reason why the grease gun is not pumping.
I switched over to a cordless grease gun, when your the only one that greases the equipment and your running mowers with around 90 fittings a mower it is a time saver. Kinda makes me think how that would do in this application.
I would think a air foot pump would be ideal for the job, cheap, pretty high pressure rating, and you have a ton of force(your entire body) to compress it, also most of them have a latch to keep closed so you don't get any back off on pressure. It's almost the same design, except all you really need to do is seal off the backplate, and tap a fitting into it.
This video left me wondering where do I buy hydraulic pieces in my town. I straitened motorcycle forks once with a bottle jack with chains attached with some scrap steel pieces. The idea of using a grease gun would have never occurred to me?
Maybe a tractor supply or farm and fleet, by the actual farm stuff. I think you'll find gears, pulleys, and hydraulic fittings in the same aisle of most places.
on your video about hydraulic troubleshooting you demonstrate how can use an infa-red heat to find internal you allready be aware but you can apply the same method for finding problem bearings i would use this tactic to find problem bearings in forage harvesters and combines both use many large bearings which can be hard to acces
I think the grease fitting (Zerk fitting) itself provides the check valve so the grease gun doesn't have to...

Interesting, my first thought was now put a small motor on the hinge and you are good, but then I checkt the bay and you get small car hydraulic pumps for less than 100€. I think I will start with some of these.

Took me a while but it finally clicked in. The small ball in the grease nipple is the check valve for that system
dowty seal is what you were after. Good lesson on the 1st rule of hydraulics, everything going to get covered in oil!
So with just a $20 CDN grease gun+ $250 worth of check valve and fittings, I can almost sorta make a sub harbor freight porta power? awesome.

That’s what I was gonna say. For what you have in fittings, you could have easily went to horrible freight.

The testing I was involved in was for hose reels and we were pressurizing the components internally, not externally. Primarily deep sea equipment and safety reels ("jaw of life" reels were certified to 10,000psi, for instance).
The grease gun that you used here was only made for general purpose greasing not high pressure. If you get one of the ones with the long handle on them and not just the little grip handle, I believe they are double the pressure. Still an interesting video though, cheers!
speaking of the pneumatics. I was working on Press 76 A 2500 ton Danly stamping press. We were stamping Torque converter bowls for Generous Motors. 8 die stations in the press. All the draw plates in the dies use nitrogen die springs. Lloyd the die maker is working on one dies. He emptied the die springs to lower the draw plate. Time comes to refill them he puts the QD connector on the inlet. Bob the foreman is standing over Lloyd the Die makers shoulder like there is some part of this job that requires the skills of a man knowledgeable in the use of a clipboard. Lloyd the die maker goes over to the cart with the Nitrogen bottle on it. Bob the foreman stays where he is. Lloyd the Die maker opens the valve on the bottle. When the Draw plates rise back up with a clank the QD fitting fails. 15 feet of high pressure hose and a brass QD fitting are whipping around the floor. Bob the Foreman is hopping around trying to get out of the way, He gets tagged 4 times in the legs and ass before Lloyd manages to shut the gas off.
@5:57 - "Steady Drip", that was my nickname back in high school.
I think that yellow cutting mate pattern is constantly effing up with camera feckus. it just locks on it...
When I calibrate high pressure gauges, i typically go up to ten thousand PSI with a hand pump. Hydraulics are pretty convenient.
"Focus you fuck" has become a happy theme to this channel... bravo my good man.
This is about all we're gonna get out of this little guy. . . . he says. Wow, not only was it impressive to see how much pressure you achieved but I was surprised at how fast it got there. When you consider how long it takes an air compressor to hit 150 psi, I'd have thought anything past 500 would be pretty slow going.
that's because this is a non-compressible fluid unlike air, so you're not wasting nearly as much energy heating up the fluid or compressing it. it's just a translation of where the force is applied.
Agree 100% that there are no grease guns that actually work, or work for that long
BOFO, one to keep for that special time! Just wish you had this on about 1 year ago, would have saved me a few pascoes. It just doesn't end!
Love your videos AvE, I have no idea waht most of this is but that's a pretty kick ass little doongle you got there
AvE, your vidgeos are great. Funny and entertaining yet informative.
if you take apart the fitting where the grease gun hooks up to the zerk fitting you will find a check valve in it ( the little bit at the end of the hose from the grease gun you removed)
You give off this John Malkovich vibe from the first Red movie. Funny as hell XD
That's pretty good hose they are using on those grease guns.👍
some off the old Lincolns say 10,000 psi on the handle. I think 7,500 today. even the battery one ($400). with grease. that's actually the pump you tightening tracks on heavy equipment with.
It's called a Dowdy washer here in Northern Ireland. Derek
Ave your too cool been binge watching your videos and actually learing new things keep up the great work
3:47 that’s what I hear every time I get a massage with happy ending
Hey AvE, another great vid: funny and informative.
Question: how do you bleed the pressure off of your system? Just unscrew one of the fittings? Would you end up wearing half of that ATF you pumped in there?
I can actually think of a couple good uses for something like this and may build something bases on this concept so I'm curious about the bleed-off.
More of this please. This was very informative.
Used to work with large jackhammer cylinders and those used on the back of skip trucks anyhoo was involved in a catastrophic failure narrowly being missed by the piston whilst my workmate wasn't so lucky and was sent across t he workshop as the side of the cylinder ruptured during a test. Our health a safety concourse employers didn't see fit to fit a screen of ballistic plastic so the poor guy took the full jet across his ribs. He wasn't badly hurt but did pass out and was taken to hospital and was leaking hydraulic fluid from the impact sight on his ribs for a couple of days.
Thanks for the hydraulic injection link. As thanks, try searching for krokodil - also an injection injury.
How about a bottle jack for something like this? Wouldn't that cut out a lot of the extra parts you need here? Great videos, love them. Keep up the good work.
Great stuff "Dowty Washer
Nice:) my grease squirter was sacrificed to make a hydrostatic fluid pump for the Morris !!!
+Lyle Gallant Yay for hydrolastic suspension :-)
Really nice video but Hydra Mac has used Alemite 500 with hydraulic oil to lift the top cover on their Commander 4200 skid steer I think year 1998. I didn't see check valve in line that could be the reason why the grease gun is not pumping.
I switched over to a cordless grease gun, when your the only one that greases the equipment and your running mowers with around 90 fittings a mower it is a time saver. Kinda makes me think how that would do in this application.
ah the good ol days of simple and direct videos. just fittin's and a grease gun. much entertainment
I would think a air foot pump would be ideal for the job, cheap, pretty high pressure rating, and you have a ton of force(your entire body) to compress it, also most of them have a latch to keep closed so you don't get any back off on pressure. It's almost the same design, except all you really need to do is seal off the backplate, and tap a fitting into it.
"My propensity for homo eroticism aside" I never know what oddball thing your going to throw out..
AvE that caused some chuckles.
Send that setup to pug1 for his log splitter and it may actually split a stick or 2 this century, BMP.
This video left me wondering where do I buy hydraulic pieces in my town.
I straitened motorcycle forks once with a bottle jack with chains attached with some scrap steel pieces. The idea of using a grease gun would have never occurred to me?
Maybe a tractor supply or farm and fleet, by the actual farm stuff. I think you'll find gears, pulleys, and hydraulic fittings in the same aisle of most places.
Holy crap; that's pretty impressive. That's what she said.
Thank you for your time and effort on all of this, i get to learn shit i might never use and have a good laugh too...
I believe the name of the seal you were looking for is a "dowty washer".
on your video about hydraulic troubleshooting you demonstrate how can use an infa-red heat to find internal you allready be aware but you can apply the same method for finding problem bearings i would use this tactic to find problem bearings in forage harvesters and combines both use many large bearings which can be hard to acces
I think the grease fitting (Zerk fitting) itself provides the check valve so the grease gun doesn't have to...
Interesting, my first thought was now put a small motor on the hinge and you are good, but then I checkt the bay and you get small car hydraulic pumps for less than 100€. I think I will start with some of these.
Late night uploads. Nice to wake up to!
i never knew grease guns were capable of high pressure. quite interesting
Bonded washer seal is called a ‘ dowty or dowdy ‘ seal in Australia
