Add a buzzer to the circuit for the PTO light. He won't forget to disengage it again.
dennis smith I have a buzzer and a strobe light in the cab!!
FUCKIN drivers don’t give a shit!!
@@Jerzeyguy Lol....
In my 35 years of experience driving a dump truck the driver left PTO on.
When I had drivers I put a buzzer on the PTO switch to keep that from happening.
$32 per/bucket AW-32 HYD OIL www.walmart.com/ip/AW-32-Hydraulic-Oil-Fluid-ISO-VG-32-SAE-10W-5-Gallon-Pail/792140101
Yup,nailed it.
Of course we want to watch you take the pump apart. Thanks for all the great videos
Looks like our buddy is not going to take the pump apart and repair it.
The intro NEVER gets old !!!😅
It probably did need a pump, but I'm not sure about that diagnostic technique. With the sleeve installed, closing the valve on the return line will basically deadhead the pump. It cannot circulate internally or through the tank. My guess is that closing the valve causes pilot pressure that shifts the valve and raises the bed. I'd be really careful about closing off the return line.
my thoughts also on diagnosis technique!!!! the pump is flowing we can see and closing the bypass would send flow to the valve and with all that flow its gonna "leak by" (they have clearance built in valves) and it going up is only because the ...forget technical term but the greater surface area on bottom of cylinder will win over the same pressure on the down side of cylinder. pilot id think would just circulate within pump? but who knows??
It's probably an open centre spool so the oil from the pump get directed through the third line when it's in the centre
Love to see a video on that old pump taken apart
You don’t run a filter on hyd system, cheap and easy, also I always used a floor jack to mount them , also start bolts with a rubber hose like spark plug, never seize
I won't run a filter on a hydraulic system either....
30:24 you left your socket on that bracket mount ! lol hope you didn't forget it always hate that on the job !
Seen one of the blue ones on 71 last night. Sharp rides, like all the lights!
If your dump trucks dont already have them. Go to your parts supplier and ask for a automatic cut off PTO lever. It has the up and down lever plus the pto engage switch. Whenever your drivers put the lever to lower the bed it will automatically cut off the pto. Did that to all my dump trucks and have not had an issue with burning pumps.
I see a total system drain and flush in your near future. And check your screen at the tank end of the suction side. Doesn't take much shrapnel in a hydraulic system to cause more grief. Been there, fought with that.
Hey is funny I like when you said on the video that you wife said stay all night down there and fixed it’s good video you are awesome man
Angle wrenches are a life saver when you need them. look at some large service wrenches also.
Nice interested video man I like the way you talk. I try to figure out with americantrucks specially dump trucks they have only one type of truck but the European trunks there are more strong and more accessibility when you need to fix something 4 axle truck carries gross vehicle weight tons 45 to 60
Another idea run front tires up on,some 4x4 blocks, not think 4 in be a lot of,room but it is . Then anit seas on input for pump the,splines
Nice job, doing it yourself must save shitload of cash.....love the channel 👍
That intro 🔥🔥🔥
OMG...You had me fucking laughing the whole way through the video listening to your comments as you were taking this pump off and on...You are so funny and I mean that in a good way...Thanks for sharing these repair videos with us.
justin why dont you make preventive maintenance like oil and filter changes for the new trucks
Great shit buddy!! Thank you
Thanks for the good helpful video junkie your good at explaining details made it easy to follow 👍👊🏻
Did you make a video if pump dis assembly and how it works?
Justin !!! Thanks for fuckin taking the time and showing us how to fucking do the job right my friend 😎
you should do another video of you hauling or driving! that long one you did of paving was my favorite video!!!! your awesome though keep it up junkie!!! you da boss
I wouldn’t be a hydraulic fitter for all the tea in China. Good work junkie I felt your pain!
Driver left the PTO in while driving cooked it
Looking good!
Hahahahaha, The cursing and groaning, is like watching myself doing the same thing , only difference is I’ll cursing the drivers name about 100 times, good video!!!👍🏻
At least they put valves on it and it didn't keep leaking . Most hydraulic stuff makes a big mess to work on it.
Lol sounds like me when I’m wrenching
Also guy, I want you to know. You’re my hero, I literally say and explain shit the same way you do. “Fucking junk, nukes it, what’s going on fuckers”
Hello tell me to adapt the pto to a semi truck do you need a new transmission or you just adapt to
This brings me back to last summer . Work was slow making vacuum trucks , so we took on a contract for a local company needing dump bodys . They had used raggedy chassis that were coated in dirt ,rust and grease on underside lol. Every single word out of my mouth for 10 hours a day was fuck or you big piece of shit lmao. We had to swap the ptos out to new ones for the dump bodys and add some heavy duty parker pumps on them. Getting to the top bolts was a real pain, lots of choice words were said about engineers 🤣
How are things Junkie? Hope work is kicking man! Hows the little guys? Awesome videos as always
What’s the serial number on that Permco and the pto please
Love your vids i just started working at a truck mechanic shop cleaning and helping out on odd jobs what tools do i need to start out
Phoenix Smith basic hand tools. Wrenches, sockets, ratchets, screwdrivers, prybars, and such.
@@jonathanford8217 any brands you would recomend been looking at craftsman and takton
Phoenix Smith it’s what you can afford. I have bought a lot of Snap on and Mac but I have been in the game a while. Gear Wrench makes some very good products and they are priced decent. Tekton is alright. Stay off the tool trucks for a while until you know for sure this is what you want to do. You can get sucked in FAST with that shit.
@@jonathanford8217 the other guys use snap on but fuck that prices for now i will look into gear wrench thanks
I usually tighten a fastener until i feel it coming loose then i no its good
Good stuff Junkie!!! 👍🏼👍🏼👍🏼
Just replaced mine today 🤦♂️ $800 for a new one and it was heavy af to put on, and it didn’t help that the new one was kissing the transmission!!
Did ARM put a defuser on return side in tank ? Check it Junkie
Appreciate the video. One question. If you have trouble engaging the switch inside with difficulty is that representational of the spool valve? If you covered that part I missed it but I'll rewatch. Thanks
Had the pto on my tri axle while a driver was driving it for at least two hours. Now it leaks at the hydraulic tank and underneath the lines are all wet and driveway is stained. I will test the pump like the lowrider guy told you
Love the how toos bro
Keep working hard Junkie!
Great vid Junkie its always a bitch getting bolts to start and hydraulic lines are so fun getting the threads to line up I felt your pain. Please do a tear down on the pump
Oh I don’t work in big trucks I work on trucks for me and my niebor had no idea and I thought working on my brothers 6.0 he had plugs
Should be able to change parameters and derate the truck while PTO is engaged. Over a certain soeed, say 15mph it won't go any faster.
take it apart plzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz
I like this guy!
How do i bleed the air in the pump?
Mr junkie I would like to see the video of you taking tha old pump apart 👍
I usually shut the Pto off one the box gets to the top
How often should I change the hydraulic fluid? It's like no one knows about this.
That's a loaded question because there are so many variables. How many cycles per day / week / month do you go through? Typically most manufacturers recommendation is about 3-6 months. At a minimum it should be twice a year. Much like your engine, keeping clean oil in your hydraulic system will ensure your system lasts longer. Furthermore, it may help you catch an issue before it happens in the field. The last thing you want is a failure when your dump truck has 30 tons in the bed.
Great video
Good video.
The pump should be able to be rebuilt and it is always cheaper to rebuild instead of replacing
Possibly, unless you end up having to take the truck out of service again because you tried to cut corners. Dump pumps are cheap and sometimes it's worth every penny to sleep well at night knowing you're covered under warranty.
My boss put me in a dump truck.
PTO switches off when you lower the bed. But the wine from the trans sounds like the PTO is still engaged.
Oh. There is no way for me to check the hydrolic fluid. No sight gauge antisyphon baskets on the filler and vent. Our shop mechanic is a parts changer at best. Boss is a know it all.
Ur the man!!
If you dont flush and drain all the old hydraulic fluid and replace it with new one you gonna have to change the hydraulic pump again…
How often hydraulic fluid should be changed? I have asked my mechanic and body builder and they look at me like I'm asking a wrong question.
nima maleki you dont need to change it if you dont break it as long as the fluid is clean and dont over heat your good
nima maleki depends on what kind of oil you’re using, what you are using it for, how often you change filters, how much fluid there is, whether or not it’s been contaminated ever. Lots of different variables for hydraulic oils. Consider taking an oil sample and sending to a lab if you aren’t sure. It’s cheap and the report should give you some guidance for your next steps. Looking clean isn’t an indication of the quality.
@@benjamun3058 thanks for the reply. I bought the Truck brand new and drove it myself for 6 yrs and just recently sold it. I once had a problem with it and changed the Air module. it cost me $200 bucks. Never changed hydraulic oil on it. But I made sure it was always full. And it didn't have filter. Now I just hope it doesnt break under the new owner anytime soon since he's a newbie and started with no money.
Shooey.
mdlee52 shoeweeeeeee
My brother is a deacon in the church good Christian, but cusses like sailor when working on his truck
You should work at a Stukeys truck stop.
If you would have old pump with aluminum cover you would knoiw ith out testing is pump, because aluminum cover have only come bigger and not more tight of inside.
Saw the title. Instantly thought to myself. "Well I've done that. There's gonna be a lot of cussing in this one..."
I wish I lived closer to you, I would give you a hand. But it doesn’t look like there’s much room there for my big ass to get in there and help anyway. Looks like stubby wrenches would have helped. And the 4way angle wrenches are nice, I have a small set of those and they got me out of a few fucked up situations like this. I agree with you in it looks like the pto was left on while driving down the road. You would think they would come up with something so that you would not be able to do that, I mean with all the new technology shit we have now, WTF! After watching this I would much rather work on brakes or something that doesn’t require going under the truck on my back, yup this cold weather SUCKS BALLS!
Hell yeah tk it apart.
Hey Junker...... I’ve run a transmission driven hydraulic pump for dang near 24 hours a day. Day after day in a snow storm. Can’t shut them off. They run the plow, salt spreader and bed. Never and I mean never did we have a pump go out. Mind you we have had pumps shit the bed on the spreaders and what not. But never the main pump off the tranny. We do have a filters. I’m not the mechanic you are, but I believe you either got a defective pump or there’s a contaminant/metal shavings in your fluid. Do you have a filter? I’m retired in Pa., wish I was closer. I’d drive part time for you if needed. Can’t beat driving new shit. Great videos..... love the content.
Where can i buy hydraulic pump?
Fucking A run it down till it strips a d back it off 1 turn just right
i have changed one they are very heavy
Yeah, and the lines are stiff as hell and always slippery.
Is saying fuck loosen locktite better?
You aren’t going to rebuild that pump. It is a gear pump the gears eat away the housing over time that is probably why the was metal in the oil
Good video but schematic would have clarified things for novices. Thanks you. and thumbs up. Mike
Goood videoo take It apart plz
Is your driver in trouble for breaking it?
Why should he?
@@Adiiii87 didn't say that.
Slick Nick is at iy again!!
@@Adiiii87 should be fired
Driver may have over rpm the pump , like he said ran down the road with it on
Tear the pump down would be awesome see
Truck doesn’t even look that old. My 2019 peterbilt is SLOW AS FUCK. Its a super dump. Takes forever to raise and lower
WHAT, no warr-en-T ??
It says the pump weighs 71 lb. Ho Lee fuk all yeah it weighs that much, LMFAO
Yes I can confirm the 2-1/2" Gear Width 7/8- 13tooth spline shaft pump is a heavy monster. It is STRONGLY recommended to make a bracket to brace this pump to the transmission. The transmission moves while the truck is in motion and you want the pump to be braced to the transmission and not a crossmember otherwise you could cause the flange on your PTO to leak.
Niceeeeeeeeeeeeeeeee
Junkie why is this not Warranty? downtime? problem with dump trucks they always need something
If the pump is left on and the gears inside the pump are burned, the warranty will almost always be declined. I would think it's safe to say that if a dump pump fails pre-maturely then 9/10 times it would be due to improper use.
#metricshiton
Are you sure you weren’t a Sailor in another life?
Your videos aren't showing up on my subscriptions page. FUCK
being fat creepers suck!!!!!! I hate them.....
Everything about a pto fuckin sucks. Been there. Beats doing it in a fuckin snowbank thoe.
Probably would have more like, if you didn't use the words you use, not professional at all, sound really bad bruh, ask the Lord Jesus to help you, because he help to stop, Amen, peace be
