50 years ago I worked as a hydraulic mechanic on bucket trucks for tree trimmers. The valve you are talking about is sometimes called a "rush" valve. As long as the pressure stays balanced on both sides of the valve the spring will hold it open. If for some reason the oil "rushes" out the unbalanced pressure/flow will close the valve off completely. All "man" handling equipment are required to have these valves.
Here's what I've learned about "cotter pins", always check you jacket pockets!! LOL I've always just put new ones in, didn't have to worry about them breaking after re-inserting. Great video. Cheers :)
Thank you for taking the time to explain how the hydraulic circuits work. Im trying to understand hydraulics and your sharing knowledge awsome. Great videos
Good job Warren. Figuring out those Sunny D plumbing jobs on their forklift conversions is a nightmare. Never have understood why they don't just put a new 5 valve bank on there when they install the clamp. Always a cluster.
Warren, you are super hard core. I love watching you fix all these different problems. I am not sure what kind of boots you wear working on a cold slushy day but you might want to get some Sorrels with a wool liner. They offer no protection from dropping a heavy part but your feet will be warm and dry!
You definitely made the right decision by getting the new service truck. If you didn’t have it you would be in a mess with the 6.0 🤮 her guts out. I may be weird but the sound of a 2 Stroke Detroit gives me wood. Keep on keeping on!
Yeah when I was a kid in Minnesota until my 20's we always had snow storms and lots of snow then like you said lack of snow for several years and now it's more like normal with the all the cold and snow. But according to the tree huggers all this snow and cold weather is because of global warming or climate change what ever you want to call it.
I've got a 3-point backhoe on my tractor, and one night when I was trying to finish a job, when I used a control it would run to the end of travel and start the relief valve squealing. I would have to shut off the hydraulics on the tractor each time it happened. i assumed that I was going to have to take the whole valveblock apart (I figured that a valve was sticking). The next day when I went to take it up to the shop, I noticed the hydraulic oil level was low. I topped it off and it fixed the problem. I had assumed that the low level would just cause the thing to stop working, but I think that air in the system was getting in between the two relief valves (one on the tractor and one on the backhoe) and making them vibrate and lock up.
" I hate it when i fixed something but, i do no know what i fixed ", been there done that. Screaming jimmy nothing sounds like them. Thank you for letting us watch you scratch your head lol.
Check the transmission numbers you might have one you can swap the gears in it to make a overdrive and then add the splitter box on the back for double over. Not sure if the mini 9s you can just add the splitter kit to get a single overdrive.
The difference between the Fuller 9-speeds and 13-speeds is just the auxiliary box, the 3/4 gear swap, additional air lines, new shifting stick control knob, shorter drive line. The transmission top plate can remain the same, as that would just make top gear to the right and forward (not back as it is now on your 9-speed). Quite a few years have passed since I performed those changeovers, so I probably forgot something. Tommy would know about the necessary changes.
The guys that look at production numbers always think max RPM works best. I ran a loader for years and never pushed because slow and steady doesn't have much unplanned down time.
I bought a set of service wrenches from harbor freight. Little short handle open end only that go up to like 2” or something. They are handy when fighting stuff that’s too tight for hand but don’t need the big end wrenches
Robert Quast bahco and snap on make mouth adjustable wrenches, I have found those to be very useful for spinning fittings in and out, obviously a wrench is the way to go though. A set from HF would probably be the same price too!
I , ty for the vids , I am glad I watched all the way thru , as I was thinking of a internal collapsed pressure hose , But it seems the O rings and needles and seats will likely be the falt , Question can the needles and seats be replaced and all new O rings in the valve bodys / Both now ,,to just get serviced when it acts up again ?
I worked for Detroit Diesel for ten years, and I love the sound of the 53's, 71's and 92's...and on rare occasions 149's. Thanks Warren, I enjoy watching your work. Good luck to you and be safe.
Thin the oil out or those old forklifts will drop slow we add some kerosene in the 10 weight oil when it turns cold and it evaporates out when the weather warms up did it years doesn't seem to hurt enything lots of hour on machine no pump problems
Next time you run across something like this try a infrared temp gun or thermal imager I suspect your problem might have been that relief valve you hammered on or a sticking bypass back to tank
It was the O-rings where that needle and seat was worn the needle and seat is worn that should be a smooth surface I would get a replacement needle and seat it probably has a replaceable seat inside that priority valve that you swapped!
Hey Warren I got to thinking about the fuel economy comment and I had an old man bring his 4240 with 12000hrs into the JD dealer I work at and he swore running it a gear under and wide open was the key to it's longevity. He claimed he'd rather burn more fuel than pay for parts breakage. I dunno just kinda made me chuckle. RPM doesnt really apply if you run it balls out and a still a gear too high like what some guys do.
Ironically ?.maybe i met a service mechanic in the 90s who had a black lab named trouble. He always said it was because his mom told him as a boy everywhere you go trouble follows.
I remember the Timber jack skidders with Detroit diesels...I bet on a cold quiet day you can still hear them screaming through the mountains....As you were working on the hydraulic valves on this...I was tearing apart spool valves on a hydraulic tire changer...my project didn’t make it...I found metal in the system...one of the valves looked like a wire wheel shit inside the valve body....18 years old not worth fixing.
@@westerntruckandtractorrepa1353 This has been used to the extream!... Problem is.. There not made very well... This customer does production AGG tires, skidder, grader... In volume...dam parts are so expensive and hard to find...
western truck and tractor repair Yes , our fleet is anywhere from the mid 70s to about the mid 2000 s and actually quite reliable and fairly easy to fix
That is your new service truck ? How do you like it ? How is the fuel consumption , compared to your previous truck ? Thanks for the video . :-) Wyr God bless
Isn't it just a kick in the ass when you get something working and you aren't sure what in the hell you did to make it work? Tell you what though, that Detroit in that Hyster sounds really good.
Illinois is about raise the minimum wage to $15.00 hour over 6 years - talking about California and Washington - if the Governor signs the bill which people say he will
I agree, that wages should go up, but the only problem I see is that to offset the higher wages employers have to pay all the commodities are going to go up as well so your really not gaining anything.
I was learned hydraulics will always take the path of least resistance , you could clean a relief valve with a white handkerchief and not see the piece of shit stopping everything form working

Warren your at it again dude!!!! Watching your videos no matter New or old always love learning something ,thanks man!!!!
It's usually more satisfying to have something fail that makes sense than to have something work that doesn't . A true dilemma for any mechanic .
Don't forget your little torch. Keep it up your doind a great job.

Love the videos and like the fact you take the dogs with you to work.
Awesome video! Love the sound of that 453!
Sound really positive and happy Warren, hope everything is good with you. The conditions are certainly not.
Looks like you are really enjoying that new truck! Great video!
Thank you for taking the time to explain how the hydraulic circuits work. Im trying to understand hydraulics and your sharing knowledge awsome. Great videos
At about 27 mins in. I was like “I can’t see shit “ lmao 😂 iv learned a lot of knowledge from you videos ! Keep um up
Just started watching, great stuff cheers from down under...🤠
Some of the fork lifts I worked on the drop restrictor is in the bottom of the cylinder spring loaded washer with holes in it
Great video Warren.
Another good Hyster resource is Dan's Equipment in Vancouver bc ,very knowledgeable and helpful company
Thanks for sharing bud nice video 👍! Hydraulics can be a real pain in the ass sometimes but you got her now !
thanks for shareing your job !
Love your videos man!🤙🤙

Love the sound of them Detroits!
You are a gifted mechanic ! But boy definitely not a singer ! Good to see you having some fun. Hang in their and don't let nincompoops wear ya out!

You get a like for the laugh when you knocked the snow off the roof !!
built 35 drawers in my shop, cant find anything. thanks again. got up at 3,30in am to see.
This man just really loves his dogs
Love the dogs
" I hate it when i fixed something but, i do no know what i fixed ", been there done that.
Screaming jimmy nothing sounds like them.
Thank you for letting us watch you scratch your head lol.
In the tube you took out the needle after you pulled out the a screw on valve and when you put it back together you put the needle after
Pilot operated relief valve could be plugged up
favorite enginer saying my book says or my school says from the word of the machine god...
OUCHY a little grease on those side compartment door springs please warren , for us headphone wearers lol. I'm now deef
Man that jimmy is awsome ,I mean both of them❤

Not sure if the mini 9s you can just add the splitter kit to get a single overdrive.
U the man!!
Those are always head scratchers … Not sure what I did; But it is working now. :)
You had to show it who's boss that's all good job ...
Engines typically are most fuel efficient at peak torque.
The difference between the Fuller 9-speeds and 13-speeds is just the auxiliary box, the 3/4 gear swap, additional air lines, new shifting stick control knob, shorter drive line. The transmission top plate can remain the same, as that would just make top gear to the right and forward (not back as it is now on your 9-speed).

Good job
Dam good job
its a pilot operated check valve

Old hyster yard lift with a 4-53 . Great old lift .
I'd love to have one; I don't have a thing I could use it for, but I do love those old Hysters.
Ever use the straight jaw nippex plyers there great for air lines hydroulic lines you name it
frozen fingers hurt like hell when you hit them, more fun when you add in oil
u will always find someone that wants to fight with u on the youtube in comments they don,t have a life.
Warren call john Deere in Kennedy, Minnesota they will hire you ,lots of tractors and combines work.
As long as you have enough power to pull it over the with some speed
Thin the oil out or those old forklifts will drop slow we add some kerosene in the 10 weight oil when it turns cold and it evaporates out when the weather warms up did it years doesn't seem to hurt enything lots of hour on machine no pump problems
That's funny you just heard that 2 stroke like you smelled it coming
Next time you run across something like this try a infrared temp gun or thermal imager I suspect your problem might have been that relief valve you hammered on or a sticking bypass back to tank
Most open circuit hydroulic system don't run hardly any pressure until you pull a lever
That's pump is not an easy place to work on and the weather is rather cold also
Spent MANY hours pushing both 6- and 8V-71s around. Once you know that noise, you can hear it coming from 5 miles away, every time.
Beautiful work, please next time set camera well, I love the video, thanks
On the pin I said to myself half it you heard me in Michigan old navy ams
It was the O-rings where that needle and seat was worn the needle and seat is worn that should be a smooth surface I would get a replacement needle and seat it probably has a replaceable seat inside that priority valve that you swapped!
Cotter pin first half assed thing ive ever seen him do
My old pickup gets 7 with it on the floor or running 55 at 1700 rpm
Warren, do you ever see any bigfoot out there while you workin' on some of that cold snow-covered iron beast?
Hey Warren I got to thinking about the fuel economy comment and I had an old man bring his 4240 with 12000hrs into the JD dealer I work at and he swore running it a gear under and wide open was the key to it's longevity.

Your hands are so tough in the cold
is that a nascar steering wheel on that forklift ,no nut on it.
That system if you pull the up I don't think the bale squeeze will move the way it's plumbed
How many tool boxes do you have I see in one shop u got one and in another shop u got another one.
Maybe oil and filter change on the hydralic would be god to do.
Ironically ?.maybe i met a service mechanic in the 90s who had a black lab named trouble. He always said it was because his mom told him as a boy everywhere you go trouble follows.
Warren,
Was it an old 2 stroke Detroit or Sasquatch??? Inquiring minds want to know. Left a cliffhanger!! LOL.🤔

Never old kit is often far better than the new plastic clad computerised bullshit especially when you look at how expensive it is compared to old kit

The deck is definitely stacked against the working man.
So who seen the missing cotter pins. I did. Right in the middle of the steering wheel.
Is the problem weather related? Maybe water freezing in the system?
The commenters tickle me. You don't know shit, but somehow manage to figure out how to fix things. Ain't it amazing Gracie ?
Could have been has simple as a relief valve sticking.
FIX IT FIX IT FIX IT FIX IT FIX IT
Maybe it is not getting full pressure all the time
I was learned hydraulics will always take the path of least resistance , you could clean a relief valve with a white handkerchief and not see the piece of shit stopping everything form working
Maybe that lad doesn’t care about what revs he operates at because the Boss or daddy pays for the diesel.
I didn't catch that everything was slow should of watch longer I guess
You are going to need a sleeper cab if you bring any more pets.
What happened to global warming there mate
It's no global warming, it's climate change. It changes all the time, it's called seasons. Lol
