- Resealing the main lift cylinders on my Clark GCX forklift. It's not as straightforward as I hoped.
These are the picks I used: amzn.to/49zKhzb
The shafts will bend if you get too crazy with them, but they easily bend back. Overall they work pretty well.

I have a forklift mast (not sure of brand though) that I modded to mount on the tractor 3 point. It needs seals so this was a very topical video. Much appreciated. Thanks for anticipating the pick question ... too bad they seem to be double the price in Canada . Was also wondering whether it was any special grease you used during assembly. I'm sure you much have mentioned it, but what are those orange gloves you prefer? I think it's time I started wearing gloves more often.
Hope you start feeling better soon. In the same boat here too. My wife is in worse shape ... after spending half a day in emergency yesterday we now know that for her the root cause is her asthma, so with some updated drugs/equipment/regimen things are improving already.
Thank you for the playlist, hadn’t realised I’d missed it! Throughly enjoyed catching up.
Hopefully u didn't get hit from the rounds of tornadoes this past January and February. Hope u all have a shelter. Thank you for sharing the link on the picks
didnt have any jabs did you.. take bulk V c, zinc.. D3. we dont get enough d3 from sun,, need supliments.. or fish, meat,ect rich in it..

Retired Clark forklift mechanic here. That check valve in the primary and secondary cylinders are there to let fluid that seeps past the packings to be forced back into the system instead of past the gland seals. They also let air escape on initial installation. When your mast operates out of sequence, when the secondary’s go up before the primary has reached its upper limit that is a sure sign that check valve is not functioning correctly and fluid is trapped above the piston.
I see you figured it out how the check valve worked. The GCS and GCX series lifts were among the first ones built when Clark moved it manufacturing offshore to Korea. They were still a pretty good product. Your guess about the radiator is correct, it can be removed without pulling the counterweight, it very tight but it can be done.
As far as your comment about hydraulic fluid all over the floor. I laughed my A$$ off, I’ve left trails of hydraulic fluid all over most of California in my career, you try to minimize it but even your vacuum system can’t catch it all. And most of my time as a forklift tech was working out of a service truck. All I had was a waste oil drum to pour it in. How I got it in that drum was always a sketchy situation.
I know the pain. Been working on these trucks for over 20 years myself. The struggle is real.
@@horstmuller7512 Uncalled for.
dopers of all colors love it - shoulda been. Not just one.
Toyota/Mitsubishi/Linde/Samsung have been through the fingers over the years, take the return hose off the valve block before lunch, and come back to a nearly empty HyD tank, it was the first time working on a 5FBMF, you could do it like that on a 7 series (new at the time) i used a lot of absorption grit that day.
Clark leaves a trail of hydraulic oil wherever it goes😂@@FreiherrDinkelacker
Years ago I worked in a beef packing plant as a maintenance guy. They told me never walk under a raised forklift because " $20 of rubber seals is all that holds it up". Darned inflation gets everything I guess.
I was told, "never trust a suspended load, it's always held up by $10 worth of China's finest steel."
Lot safer now days! $539 dollars worth of seals and your life.
Clark basically gouges people on seals.
If you take the seals to a hydraulic shop and have them matched up it's about $100 for everything.
But that means taking the mast apart, driving to and back from a hydraulic shop and then putting everything back together.
And it takes longer to do all three cylinders at the same time vs one at a time.
So you turn a 2 hour job into an all day job to save $400....but forklift mechanics charge $125 an hour.
So that hydraulic shop would have to be real close before you save any money...and if they don't have one of the seals in stock , you're just stuck.
Hercules and York usually have those kits, and whole lot cheaper. If you have time.

With a kid in school and your wife teaching, you could potentially be sick every day for the rest of your life. Thanks again for sharing
Every time our grandchildren ...AKA terrorists ... visit my wife and I catch some kind of viral disease.
Being sick is the worst. I had the flu this winter and was down for 2-3 weeks.
They all spread it around. I feel the pain with a child in school
I like the intelligent approach you take to explaining things. I come for entertainment but also to learn a thing or two. Scrappy is the same way. Feel better Wes.
I have to say you take a lot of extra time to draw the diagrams to explain things and how they work. I thoroughly enjoy seeing them and understanding how they work. Thanks for taking the time to do that....
While in school in the early 60’s, the pad of green paper with the grid on the back side was called engineering paper. Great paper! I enjoy Wes’s always clear and understandable explanations.
You hit the nail in the head with that explanation on cylinders, it is indeed for cushion and smoother operation. Remember that these machines were once new and built for loading and unloading valuable goods, not so much towing rusty cars in & out of shop 😁
Wes's machine, not so new, is just multitasking, those "Don't Tow" stickers must be missing. The shop I once worked at had an old surplus ClarkTowTug, used it for plowing.
At 6, watched Captain Kleeman work on trucks, at 7, I watched you rebuild cylinders, yet in my shop is a broken truck, and next to it sits a dozer with two cylinders that need to be rebuilt. Yet here I sit, watching y'all. If you needed proof that it's more entertaining to watch you work than to work, here it is! (Thanks for the video!)
I know that feeling! I also watched Kleeman just before watching Wes. I have a 96 Thunderbird in my shop that needs work, an 07 Acura behind that and another Thunderbird after the Acura. It's wet and rainy out and it's way more fun to sit and watch sometimes rather than go and do!
You started young
Guilty here in key west lol
I find work fascinating. I could watch it all day.
i have a car (FWD) that needs a timing chain, i have another car that needs rust removed and heaps of other small problems, and on to that another car that needs its fueltank replaced with a better one still i sit here watching other people fix their machines/cars... watching is a whole lot easier to do than doing it 😅
You are an oddity. A mechanic that has a grasp of English and grammar. Such a joy not to have to cringe every other sentence.
It’s called being an engineer not just a wrench monkey.
You just made a blanket insult for mechanics. You shouldn't throw stones when you live in a glass house. Looking through your past comments reveals more than a few utterly deplorable sentence structure flaws. 😊
@@googleuser3110 if I did, please correct me. I'll take it as constructive criticism and get better. I won't throw it back at you like, well you know. 😁
I watch enough videos and have enough close friends that are mechanics to see a trend.
I dunno. Words are hard.
😁@@WatchWesWork
I love when the pencil and paper come out. I learn something every video. Love the Chevy at the end of the video. My parents had one when I was just a kid.
Ahhhhh, the joy of working on hydraulics. No matter how many rags and buckets you use you will get hydraulic fluid EVERYWHERE!
And when you fix the leak you were after a new one pops up somewhere else because as all hydraulic mechanics know, these systems dont like getting taken down to atmospheric pressure then back to 1000+psi. Tends to piss off the o rings.
Wes Johnson Services, a great place to take a leak!
We're closed!
@@WatchWesWork Wes Johnson Services...I miss the CNC circuit board repairs. I've spent quite a few years doing NC and CNC stuff in the 1970's...most of the guys I worked with would never even take a chance on any machinery....bad enough adding a quart of oil to their vehicle!
Study at school learn form RUclips. 😮 Wow! Thanks for sharing
You sure seem to get yourself into a lot of hydraulics for a guy who hates hydraulics😁
Tell me about it!
I find your theoretical explanations to be one of the best on youtube. If my university taught us this way, I wouldn't struggle so much with it ! it was just equations and very non-straightforward visuals ...
This explained a lot. 30 years ago, our forklift repair guy came out to replace some leaky hoses and O rings. He told me to take the forklift out into the parking lot and raise the mast all the way up and leave it for a minute or two to drain off any of the fluid that got above the piston. 30 years later I still do it. Thanks for the video and I hope you feel well soon.
This forklift is so worth the love, I remember you getting it. As always enjoyed the watch, my husband not so much as he was run over by a forklift 5 months ago and still recovering. Get well soon Wes, look after yourself x
Well wishes to you and yours then.
Ouch! Hope he recovers. I had my foot run over by one as a kid. Luckily it just barely nicked my toe.
Ouch indeed. Two broken arms, broken ribs, broken nose, bleed on spleen and lots of cuts & bruises. Still off work as the wrong side of 60 to be run over. Here to talk about it so very grateful x
For sure.., the videos of its’ repairs were some of the first videos I was made aware of Wes’s channel. Fan ever since.
Speedy recovery for your hubby.
@@SueSmith-ew7ivI doubt there’s any side of 60 that’s right to be run over by a fork lift. Thoughts for a speedy recovery to you both.
Wes I was there (subscriber) when this machine was pulled from the sticks! The machine is an important part of your shop.
I remember when this channel was called Wes Johnson Services and our hero was fixing CNC machines and the like. What a trip it's been.
@@zspolson. Ditto. Do you remember his transport IH truck?
@@Military-Museum-LPThat old rollback, right?
@@zspolson. Yes
I'm so glad you explained how a displacement cylinder works. My brain was beginning to hurt trying to figure out how a hydraulic cylinder could work without a piston. So it has a piston, just not a "piston" piston. 🤪
It is a piston, kinda.
True displacement cylinders without a piston had a much larger ram - made from tube rather than solid, not much smaller than the cylinder bore. If you think about it then it has to be so otherwise the cylinder bore size is ''wasted.'' The first tractor front end loader lift rams mostly used cylinders like that - power up but no power down.
@@julianstafford7071 The displacement cylinders with a machined bore and the rod matching the ID of the bore are also safer. If the piston seal fails on a traditional cylinder the oil can jump from one side of the piston to the other rapidly and the cylinder slams down. In a displacement cylinder that space is all filled with rod so the cylinder will creep down, not slam down. I believe these are used in anything people hauling for this reason.
@@ryanslaback9418 Piston seal fails?...that's a good reason for the rule....'never stand or walk under a load'..
Thanks Wes! I hope you feel better soon 🐾🍺
I'm a retired maintenance millwright, when foreman put me in the forklift shop, I always felt I was being punished. That was a pretty good video, Wes.
Forklift shop? At least 'they' had one...I've been around these things for 50 years, the most neglected piece/s of equipment I've ever seen...Last place I worked they had a 12,000 pound Clark solid tire 'warehouse' forklift....one of the steering wheels had zero rubber on it...employers didn't see why that could be a problem....
They drove it outside in the rain, and through 7-8" or more of water in puddles...brakes rusted up so bad they barely worked...
Changing hydraulic oil, it doesn't look dirty like engine oil (also never changed) so why change it....and don't bother changing the engine oil, it's a lot of trouble if you can't get the forklift up a foot or so...but you know, if you're thinking...just a few 4X4's and you get it up there...
Wes shares his purgatory, that's why we watch;)
@@dougankrum3328It was a custom wire mill, we made wire for aircraft carrier arrestor cable sort of stuff . It was located just behind the docks so it was a cramped mill, and relied on forklifts to move the rod and wire around. They were kept up and regularly replaced, they were beefed up 10,000 ? Cats.Those steering wheels barely touched a lot of the time. But our two poor little 4,500# maintenance forklifts got no love.
Mornin! I worked on Forklifts for about 40 years, I’m glad you figured out how this setup works. Now I know also! ✅
Your drawnigs (in this video and in the past ones) are the best I've ever seen! Thank you for describing the basics so understandable.
And the best is, he can do the drawings without the help of a computer.
Old school, paper, pen and ruler. 👍
I got covid 18 months or so ago and have only just gotten over a second collapsed lung. It is no joke! If you're sick, go get checked out. It took me 6 or 8 months of a persistent cough before I saw a quack about it, which after a raft of tests showed the first collapse.
The medicine to alleviate the coof was discredited and smeared by the elite with self interests because it was cheap and it works, I took it early on because I have stock of it for my farm and was better in two days, "they" wouldn't have made trillions if we were allowed to use it. Just remember a cured patient is a non returning patient, it's all about money and control!!
Man, that sucks. I finally got it after battling it for years and all i got was... my smell coming back. I had no smell from before the pandemic. Something about my sinuses being messed up made it really difficult to pick up anything but the strongest of odors (like gas leaks, for example) and two days after my fever broke (after 4 days of feeling like death warmed over) ... i got hit with the smell of stale pillow cases (overdue due to the sickness). I freaked out so bad and started sniffing stuff up in the house. It's been two months now and the smell's gone again... CV is some frakked up banjo recital if you ask me.
Vitamin D3 is good for covid and lots more.
whatever you do, don't say yes to intubation. intubation kills more patients than covid
100%. Wes, get checked, please. Working in a freezing shop all winter, not good.
Using a hammer on the wrench reminded me of my dad. He always says "do what I say, not what I do!" =)
Hammer time...in reality, that retainer should never have been that tight. That's why those spanners have such short handles.
Wes, you are an excellent teacher! Thank you for this lesson and so many others in past videos! Feel better - spring is just around the corner.
I have the same forklift.
My brakes are shot.
The lift cylinder (multistage) pours oil.
I started to rebuild the cylinder last year and got extremely discouraged.
Years ago my dad's company built his own cylinders for his hydraulic equipment.
You know your stuff!
You are an inspiration for me to finish my own forklift.
Keep it up Wes!
You been doing this RUclips thing for so long you knew the first thing viewers... like me... would want to know was where to get the picks... 🤣🤣🤣
Clearly Wes would have been able to make a nice living as an instructor in a college level tech school. He has an ability to teach even RUclips blockheads how complicated systems work.
Why would Wes want to babysit students, his wife has a tough enough job already.
Good humor, excellent tutorials, fun repairs to watch - a deadly combination. I am so glad I found your channel. Keep up the excellence!
Always enjoy your content - thank you, keep doing what you do!
Nice teaser with the 76 Malibu SS. Can't remember the last time I saw one of those. I love it when you break out the graph paper. You are a gem sir.
Malibu Classic?
Not sure, thought it had an SS badge on the fender.@@Corey-dy2cq
I still remember when you dug this forklift out of the weeds all those years ago. All your old revivals showed me that abandoned equipment can still be useful.
Those O rings can be fun . good job ,Wes . got it back togather and no leaks .
I wondered how the sequence of the cylinders was controlled. Now it makes sense and avoiding having hoses to damage or rot really makes sense.
Thanks for the video Wes. I always look forward to them.
I missed your video this weekend. Thank you for restoring my sanity. :) You are hands down the best youtube channel out there.
Nice work - thanks for sharing it with us. Spring is just around the corner!
Thx for taking the time to make the drawings to be able to teach us more easily.
I always enjoy your drawings and explanations of how things work.This forklift explanation was VERY educational.
I love the green paper explanation! Thanks
Really appreciate your videos. Your explanation diagrams are awesome and are very helpful in explaining complex systems. Looking forward to whatever is next. Thanks, Wes.
Thanks Wes. As ever, informative for a non-engineer, entertaining and a good watch. 👍
very clear explanation of how all the different rams work!
I've been with you as far back before you restored that crane. It's been a fantastic journey with you partner
I've watched the forklift videos... and I'm gonna watch them again!
Love your stuff, Wes!
Thank you for sharing the information on hydraulic cylinder design with us, I have about 16 cylinders and had no idea there were so many different ways of operation. I learn something every time you post a video, so please keep sharing them with us. Hope you feel better soon.
I had no idea about the different kinds of cylinders (thx for the education) but you make the whole thing very interesting. Thanks for another great installment and I hope you're better soon.
Great to see you work on the Clarke. Watched since you were out in the woods and long grass trying to get her going. Keep up the good work.
Yea were in the second wave of warmth you spoke about at the end of the video. This weather is nuts man.. Awesome vid !!
Hope you feel better soon. I love how you explain everything every detail of what you're doing and the physics of it. You remind me of when I work with engineers and research and development. Thank you for sharing your knowledge.😊
Can't imagine why anybody would want to leave that hoist outside for how many years. Works like a charm, and breaks down less than anything built in this day and age.
Thanks Wes, nice tutorial on cylinder construction, seal purposes, and nice job on the rebuild. Thanks for video, appreciate your time and effort on them.
A very interesting discussion on these hydraulic systems, as always Wes; thank you!
Love this!! This is what I do constantly. Have been doing cylinder reseals on forklifts. Neat to watch your tackle one.
Great video Wes. Hope you feel better soon. Thanks for sharing. Cheers.
I had 12 Clark fork trucks years ago. You can get the radiator out without taking the counter weight off, you just need to take the seat and the plate off, if I remember right? It's been 20 years, good luck Wes.
Great explanation on the types of cylinders. Thanks.
I believe I found your channel in the 8-10k range of subs(before the tow motor - but in the same patch of woods!). Been here ever since, and have enjoyed every vlog! Keep it up guy, its a GREAT channel!
Cool video Wes and that is a really neat cylinder arrangement. Thanks for sharing how they work!
Just started my own channel here on RUclips. I watch your videos over and over again, great content and editing. I get many ideas for my own vids from watching yours, thanks. Get well soon.
It's definitely pleasure watching Wes pull apart equipment components and explaining what and why he's doing to repair them.
Ain't no doubt he'd be an excellent aircraft mechanic with his attention to detail and competence at pretty much everything he does.
Ya done good Wes. Always a pleasure to watch your jobs. Thanks
Yet another wonderful video Wes. You still have one of the best channels on RUclips!!!!!
Perfect timing. Just finished the forklift series last night!
Beautiful explanation on the hydraulics.
Green paper diagrams are a highlight for me Wes👍 Thanks for your easy to understand explanations!
Great video @WatchWesWork. Really liked this one mate. Great job !
Wes this weather has been absolutely nuts! Warm and sunny in the 70s one day, and freezing rain sleet and hail the next. Somehow the nice weather always happens to fall on the days I'm working!
WOW, a flash back into my past....that Plymouth1978 that you showed at the end looked exactly like one that I used to have, color and all, I almost forgot how beautiful that car was. 😊
Nice a forklift repair video. I’m a retired forklift operator. Excited to watch this.
The "Will It Run" video for that forklift was the first one of your videos I saw, and I haven't missed one since then. It's always great to see it show up in another video.
Thanks for posting, hope you feel better soon.
Another great video thanks Wes! Learning about hydraulics this morning 🙂. I hear you about the being sick thing Pneumonia hit my wife and I 31 days ago we are just coming out of it, get better sir! Have a great day.
awesome explanation on the hydraulic system. I'll probably never work on something like it, but you do a great job explaining, and making a unique design understandable.
your series of finding and reviving the clark was my first introduction to your channel and I have been a big fan ever since. I have never worried about you except maybe for that time that Morgan came to visit. thanks for all that you share with us.
simply amazing the jobs u tackle and r able to understand what needs doin, u r 1 uber talented mechanic, thanks for posting, hope Max and the wife r doing well
Another great video Mr. Wes thanks for the journey
Thank you for explaining how a two stage lift works!! Believe it or not, something I've pondered a time or three while operating and looking at lifts!
I need to do some hydraulic work this summer, and as I have not done any for 50 years, I appreciate the refresher course. I have watched every one of your videos, so I am pleased to see a new one. Thank you much!
Get well Soon Wes. Nice Explanation. Keep it up.
This sounds like a while i was there. Good video! And we are back at college physics class. Thanks for the memories! We are going thru the weather issues in upstate NY just like that and even the Robins are freaking out.
Love your green paper drawings and your explanations too!!
I always love your green paper engineering drawings. Not only are you an excellent artist, the drawings and your explanations really help me understand how things work. I'd watch a RUclips channel of nothing but you explaining mechanical systems with your drawings honestly. It's very educational.
I love your channel and always gives it a like even before I watch it; the chances of me ever having to change seals is less than zero but I am sure I will be able to pull it off after watching Wes's instructions !
I hope you feel well soon.
Thanks again, Wes. The weather here in western Pennsylvania has been doing the same thing. In the twenties and thirties at night and today, 72 and sunny. This has been going on for weeks. Have a great day, Wes and family.
I enjoyed watching you work on a truck I drove for years wasn't my favorite truck but it was the first new truck we had.
You always make things look easy. Good job. I have also had a cold for over a month! Head keeps draining. What a drag.
I don't know who is sick more you or Puddin but you both still have those germ breeder's running around. My woes come from Vietnam 57 years ago. Keep up the good work.
Wow, RUclips showed me your channel with the dragline video in 2020 and i didn't realize your subs have grown 10x since then! Congrats! You run a high quality channel and do good work. Thanks for bringing us along even when it's difficult. I have a 3.5 year old channel on the side that's just passed 8,000 subs so I know it can get pretty tough to keep the content coming when life happens. Anyway, keep yer stick on the ice
I love this weather. I was outside most of the day today with short sleeves. Wonderful. I'm in Michigan and have had the exact same bizarre weather with ridiculous temperature swings.
Hey Wes 👋, great video. It's great to see you out in the shop working on things. Thanks again 🖐
I remember you pulling that forklift out and restoring it, been watching you ever since...
Wes, you have one of the best channels on the RUclips! _Keep up the amazing work team Hufflepuff!_
I just wanted to say that I really enjoy your videos. I follow and regularly watch about 20 folks. I always look forward to your new videos. Been watching about 3 years. Take care Wes.
Hey Wes, I live in North Central Indiana. We were issued the same forecast and warnings. Our temps were all over from teens to 70's but thankfully the storms and hail didn't materialize here. Love your videos, keep them coming.
I'm surprised how easy that went, thought it was going to be a disaster! Thanks for making that playlist, I gotta binge watch those now.
Great “green paper” explanation.
Really appreciate the technical breakdown Wes. Imo you've got some of the best content on RUclips.
Excellent video editing. Really enjoy the content.
As always Wes your work is technically superior and the contents are superb. Thanks for yet another WWW masterpiece!
I'm subscribed since you had like 60k if I remember correctly, but already binged most of your older videos, including the forklift restoration. Heavy machinery and rust buckets repairs are what I enjoy best on your channel, so personally I'm happy you took a break from that freaking robot and hope for one more video on the old forklift.
