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.
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
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.
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.
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.
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.
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!
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 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.
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 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.
@@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!
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.
Wes is the kind of person people who work with their hands should aspire to be. Well rounded, well spoken, well educated, well equipped with a shop full of half finished projects ❤
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.
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.
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...
@@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.
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
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.
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. 🤪
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.
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.
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 ...
You been doing this TH-cam 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 TH-cam blockheads how complicated systems work.
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.
Rewatching the old forklift playlist makes me realize A) how much your camera equipment has improved, and B) how much I miss that old rollback truck you used to drive.
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.
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.
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.
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.
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.
Look at you all fancy with a spanner wrench! I use pipe wrenches, chain wrenches, strap wrenches, etc. I would need a dozen spanners to cover all the different sized cylinders I rebuild. Good work Wes!
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!
I had a 1973 Clark Fork Truck. The cylinder was leaking, the soft plugs were blowing off, the hydraulic lines were blowing out randomly every few months and I could go on. I use it maybe an hour a day and I am not as motivated or knowledgeable as you. I bought an 8 year old CAT with only 900 hours on it and said goodbye to the Clark after 45 years of service, it owed me nothing but was glad to see it go.
Clark was a renowned leader in material handling. In some countries in Europe they don’t use the word forklift, they call all forklifts Clark. The same for skid loaders. They are called Bobcat even if they are JCB or EuroMach, or what ever.
Back in the day when I ran a warehouse at a die cutting plant I used a 1973 Clark like this one except yellow. That thing never broke down but the larger Datsun was always broken.
Never change anything more complicated than a light bulb anymore, as long as the light fixture is on the ground, but I love your videos and your process of figuring things out. Hope you never run out of projects and feel better soon.
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!
It was a pleasure watching you work on the forklift again. I believe these were the first of your videos I watched - of you getting that one out of the field. And thanks for the hydraulics lesson also. Education is a wonderful thing, even if you are 79 years old. I hope I never stop listening and learning.
You have put lots of effort in to that forklift and have watch the originals videos when you had 20k subs now you are 10 times that!! You’re doing great!!
We’ve got this same Clark truck at work. I have redone the tilt cylinders a few years back and now I see its dripping down the mast cylinder. Perfect timing on the video👍
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.
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 TH-cam channel of nothing but you explaining mechanical systems with your drawings honestly. It's very educational.
We used every variety of lifts at work and Clark was the best from what I saw in 30+ years. Our forklifts ran 24/7 365 and it was nothing to see 15,000 hours on a lift when rotated out.
Sir you have the patience of a saint & the strength to hold a bull out to urinate & the equipment that you work is amazing also my apologies I have had family health issues & did not see this video drop as always Cheers mate from down under & our weather has been as crazy boiling hot & major flooding maybe there is something in this climate change hypothesis.(45 deg.c)
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 TH-cam! _Keep up the amazing work team Hufflepuff!_
We had to do the lift and steering cylinders on a Clark at our carpet store. Worked with a mechanic friend who was trained on them. It was a messed two day job. The muffler was cracked and we opted to not remove the counter weight and just deal with the noise.
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 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.
Wes, you are correct in your assertion of the cylinder operation except for one small thing left out, they use a orifice and a check valve to cushion not bottom out the cylinder. The other cylinders that do not use this use a cushioning valve that hits the gland first allowing some oil to escape and stop bottoming out.
worked in a lot of plants with some tired fork trucks. most had so much blowby theyd propane cropdust you snd maybe spray you with an oil mist. that one even leaking is not in bad shape.
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.
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!
Apart from the fascination of watching someone replace the seals on a fork lift, and it was fascinating, it's also interesting to hear about the weather. In Melbourne, where it is summer, the weather has been equally crazy. One day it was 38 deg C and the next day it maxed out at 18 deg C. It has been variations on this for most of the summer. You end up constantly chasing your tail. This morning I had the heating on and this afternoon I will probably have the cooling on. No wonder I just stay indoors most of the time, it's too confusing. 😄
Saw a video in december which predicted this yo-yo effect. Although it was about the northern polar vortex becoming unstable, apparently the southern polar vortex is doing the same, on occasion pushing massive amounts of cold air out, then retreating just as suddenly, drawing in hot air from around the equator. It could continue like that for a few months.
These are the picks I used: amzn.to/49zKhzb

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.
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.
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. 👍
That's a sweet Chevy at the end
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.
22 years working on lifts. Ya did great buddy.
Great “green paper” explanation.
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.
Those O rings can be fun . good job ,Wes . got it back togather and no leaks .
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.
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 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.
Look at you all fancy with a spanner wrench! I use pipe wrenches, chain wrenches, strap wrenches, etc. I would need a dozen spanners to cover all the different sized cylinders I rebuild.
Good work Wes!
I've been with you as far back before you restored that crane. It's been a fantastic journey with you partner
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!
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.
Wes is the mechanic that has the skills to take on anything that has a engine 😂😅😊
I had a 1973 Clark Fork Truck. The cylinder was leaking, the soft plugs were blowing off, the hydraulic lines were blowing out randomly every few months and I could go on. I use it maybe an hour a day and I am not as motivated or knowledgeable as you. I bought an 8 year old CAT with only 900 hours on it and said goodbye to the Clark after 45 years of service, it owed me nothing but was glad to see it go.
what do you expect from a 45 year old hydraulic lines, that they will hold as new?
They don't last forever.
@@ПавелКузов-ж1в umm, no.......💩
"This puller has had a hard life" immediately puts an impact on it.
I said the same thing when I watched today.😂 I just sat down to watch it today.
Thx for taking the time to make the drawings to be able to teach us more easily.
Clark was a renowned leader in material handling. In some countries in Europe they don’t use the word forklift, they call all forklifts Clark. The same for skid loaders. They are called Bobcat even if they are JCB or EuroMach, or what ever.
in Australia skid loaders are all called bobcats! a forklift is a forklift though
Back in the day when I ran a warehouse at a die cutting plant I used a 1973 Clark like this one except yellow. That thing never broke down but the larger Datsun was always broken.
Clark have certainly their own unique way of doing things. I never worked on the smaller ones, but forklifts.....always fun !
Information that I will never use but will never leave my brain.
Thanks Wes 😂
Ah location X. Lots of good videos from that field
Nice teaser with the beautiful Chevelle.
I love the green paper explanation! Thanks
Good humor, excellent tutorials, fun repairs to watch - a deadly combination. I am so glad I found your channel. Keep up the excellence!
I thought youd have to make a gland wrench but naturally you have the proper tools.
Sorry to see you're experiencing the type of weather we Albertans get all the time. You need a snowbrush and shorts on the same day around here!
Never change anything more complicated than a light bulb anymore, as long as the light fixture is on the ground, but I love your videos and your process of figuring things out. Hope you never run out of projects and feel better soon.
15:31 "You know it's getting serious when the green paper comes out." I laughed out loud - quite loudly!
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!
Wes I admire your never ending confidence in taking on all projects. Im weak in hydraulic cylinder repairs. I still take them to a specialist.
It was a pleasure watching you work on the forklift again. I believe these were the first of your videos I watched - of you getting that one out of the field. And thanks for the hydraulics lesson also. Education is a wonderful thing, even if you are 79 years old. I hope I never stop listening and learning.
Same here @ 67. lol
You have put lots of effort in to that forklift and have watch the originals videos when you had 20k subs now you are 10 times that!! You’re doing great!!
Between your channel and cutting edge engineering in Australia I have learned so much about hydraulics.
That cutting edge engineering guy is another who is not afraid of taking on big projects.
Weather has been weird even down here. Cold then warm then cold. Rinse and repeat. Love the Malibu!
Great looking automobile at the end. Real class. Nothing like the cookie cutter automobile’s of today. 👍👍👍🇺🇸✌🏻🙏🏽😎
260K subscribers in 4 years. WOW!! You deserve it, Wes. Fantastic videos.
That forklift has served you well despite its past. Nice to see you had saved it. Ready to get that radiator next Wes! 👍
We’ve got this same Clark truck at work. I have redone the tilt cylinders a few years back and now I see its dripping down the mast cylinder. Perfect timing on the video👍
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.
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 TH-cam channel of nothing but you explaining mechanical systems with your drawings honestly. It's very educational.
We used every variety of lifts at work and Clark was the best from what I saw in 30+ years. Our forklifts ran 24/7 365 and it was nothing to see 15,000 hours on a lift when rotated out.
I always enjoy your drawings and explanations of how things work.This forklift explanation was VERY educational.
Things have changed a lot Wes, keep em coming as we all enjoy your shenanigans ... :)
Sir you have the patience of a saint & the strength to hold a bull out to urinate & the equipment that you work is amazing also my apologies I have had family health issues & did not see this video drop as always Cheers mate from down under & our weather has been as crazy boiling hot & major flooding maybe there is something in this climate change hypothesis.(45 deg.c)
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!
Nice work.
Reminds me of an old joke about a walrus and a Tupperware party.
No, that's just ice cream🤣
Nice a forklift repair video. I’m a retired forklift operator. Excited to watch this.
Really appreciate the technical breakdown Wes. Imo you've got some of the best content on TH-cam.
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 TH-cam! _Keep up the amazing work team Hufflepuff!_
I missed your video this weekend. Thank you for restoring my sanity. :) You are hands down the best youtube channel out there.
We had to do the lift and steering cylinders on a Clark at our carpet store. Worked with a mechanic friend who was trained on them. It was a messed two day job. The muffler was cracked and we opted to not remove the counter weight and just deal with the noise.
I admire and always enjoy the hand drawn diagrams 🙂👍 We went from 75 to snow in 8 hours last week! 🤣
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 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.
Wes, you are correct in your assertion of the cylinder operation except for one small thing left out, they use a orifice and a check valve to cushion not bottom out the cylinder. The other cylinders that do not use this use a cushioning valve that hits the gland first allowing some oil to escape and stop bottoming out.
worked in a lot of plants with some tired fork trucks. most had so much blowby theyd propane cropdust you snd maybe spray you with an oil mist. that one even leaking is not in bad shape.
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.
Our weather up in Ontario Canada has been very strange fluctuations too, nice video Wes!
I kept thinking how much the next guy who brings that lift back to life in 70 years after you and he'll appreciate the cylinders seals. 😂
The phrase "While you're at it" can be financially scary, but it does make for good content. 😊
I swear I always learn something about some sort of repair every time I watch your videos Wes
Love your green paper drawings and your explanations too!!
I have coughing ETC, since last August. Nothing crazy but still sick for months. I hear you...time will heal....
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!
Yay. A new Watch Wes Work Video. Get to feeling better Wes.
A good design. That those seals were still working at all attests to that. Thanks for showing us how 'easy' it is to fix the leaks that plague us.
Apart from the fascination of watching someone replace the seals on a fork lift, and it was fascinating, it's also interesting to hear about the weather. In Melbourne, where it is summer, the weather has been equally crazy. One day it was 38 deg C and the next day it maxed out at 18 deg C. It has been variations on this for most of the summer. You end up constantly chasing your tail. This morning I had the heating on and this afternoon I will probably have the cooling on. No wonder I just stay indoors most of the time, it's too confusing. 😄
Saw a video in december which predicted this yo-yo effect. Although it was about the northern polar vortex becoming unstable, apparently the southern polar vortex is doing the same, on occasion pushing massive amounts of cold air out, then retreating just as suddenly, drawing in hot air from around the equator.
It could continue like that for a few months.
@@silvergreylionOh, joy.........😄
Always enjoy your content - thank you, keep doing what you do!
I have also been sick for months. It's not fun. Get well soon. Very fine video. Nice green paper talk, Wes.
