Cab is hyper-extended; it should always bear weight. Once the safety stop is able to be engaged, do not raise it anymore. In the counterbalanced position shown, there is no way for the safety bar (s) to set reliably. A hydraulic leak or bleed will allow the cab to come down on anyone below it. It won't be the first or the last casualty as a result of people setting them improperly. Suicide by gravity is not the way to do it. More importantly, why in the hell would anybody manually raise the cab on a functioning truck? The on board air system is meant to be connected to raise the cab. It is a self-sufficient design. Simply connect an airline, off of the trucks own pneumatic system, to that extra hose dangling right next to the manual hydraulic pump. Voila, cab goes up. Using the manual hydraulic pump it's meant to be a last resort, to access the engine compartment if the truck will not start. Unless my eyes are deceiving me, that is a 12-volt pump attached to the system you are cranking on. That appears to be a momentary switch on the housing, meaning there is a primary, secondary, and tertiary way to do it (electric, backup pneumatic assist, and finally manual pump). The first two of which do not require cranking your balls off!
Just a friendly note: that little rubber button to the left of where you stick that jack handle is a button used for operating that little pump by air, if your tanks have air built up, so you don’t have to sit there wearing yourself out pumping it up and down
despite there pain in the ass nature I still love cabovers now I may drive a conventional long nose Pete however cabovers will always be my favorite trucks
Nobody wants to spend 5 minutes to raise the cab of a truck just to check something simple like oil or radiator fluid. There's a reason these things are obsolete.
No wonder they did away with these cab-over's... by the time you get the thing raised up and lowered, I would have my entire pre-trip done on a conventional!!
Good point.Also its a good idea once the cab is up to its apex and starts to go over center.Flip the lever to down and feather it till the cylinder hits its end.
No not long at all actually. I got mine up to safety stop level in maybe 45 seconds MAX !!!!!!!!!!!!!! But they were well maintained trucks. This truck -- if you watch a previous video was recovered from A TRUCK GRAVEYARD AFTER YEARS OF NEGLECT !!!! It got HORRIBLY BOGGED during the recovery.
The last time I saw cab over that far it hit the ground not a good idea to go past center just go far enough to get lock in place or it might go over and blow ram seal out
My heart stopped beating at the 3:40 mark. Unless the hydraulic cylinder rods that lift the cab have been strengthened it is not unusual for them to separate and for the cab to 'face plant' with very very expensive consequences. Kenworth - Australia - knows of the problem but last I heard had not introduced a retro kit to solve it. Strengthening is usually done by the owners -- myself included. Really no need to take the cab much further than 40 degrees -----------unless the engine / radiator are coming out. Then safety chains or straps should be used to prevent free fall.
Truck engine maintenance Hooded: Open hood, do work. close hood Cab over: remove all loose contents from cab or strap them down, spend 5 minutes jacking up cab, hoping it doesn't fall on you, do work, spend 3 mins putting cab down again, replace cab contents Hmm, I wonder why hooded trucks are more popular...
Oil is usually checked by a dipstick accessible either through the front panel (a little door just below windscreen level) or depending on what manufacture engine, just to the rear of the drivers door. Coolant top up is a pain in the arse unless you have a flexible funnel; but also does not require cab tilt.
I take it the air assist on the cab raising mechanism does not work. That is what the small almost indiscernible button is for, the one at the side of the pump.
A word of advice. Always get inside and tie everything down before jacking up the cab on a Cabover! You'll end up with a busted windshield if you have anything loose in the cab. Coffee cup anything. Also be very careful not to jack it up to far. I have seen the hoist break and the cab smash into the ground in front of the truck. Not a pretty site.
Be thankful the cab jacks up most of them old cabover KWs the dog house was all busted up & if you could get the cab up it would lean so bad you couldn't get it down, kenworth made a repair kit for it it took about 30 hours to install , A bunch of old trucker guys years ago called them old cabovers front wheel drive , I remember the in the 70s & 80s that's all you seen on the road In the late 80s the length laws changed by the early 90s the salvage yards were full of cabovers you couldn't give them away they were worth more dead than alive.
Brings back memories of working in a truck shop tilting cabs. That part and the end of the raising procedure, where it falls to rest got me nervous every time! Where is the gear linkage?
It must of been quite annoying if you were a full time long haul driver. Everything in the cab would be in the windshield every time you had to crank it up.
They are fitted ex factory with a hydraulic-pneumatic pump which, when properly maintained, will take the cab to an effortless 30% ----- sufficient for routine checks and maintenance.
Notice to the general public, dont go under any cab over truck when the cab is coming down, dont put your arm under it, dont put your head under it and certainly not your whole body. Should have just said dont try this at home.
lovely old truck from the 80s era they were first class in thier day liked the shape of the cab always did and the CAT engine under the cab was a great engine the 3406 is some engine allways willing to do its best like the Cummins cheers to all you truckers out there god bless
So damn cool. I love big trucks especially older ones. I have 0 desire to ever own or drive one but they are awesome to watch. Where do you live? Looks awesome
Looks like your front tire is flat ,,you need more fluid in your pump it will surprise u how quick it goes up if u fill it ,,only about 10 or 15 pumps it will b up
looks like a double bunk sitting down to much. use 11r24.5 tires 3.90 or 4.11 ring gear and pinion (Rockwell's)--40s or 44s a good single exhaust system is OK. but that split t don't look right ? couple 86200-nelson fully baffled mufflers are quite and FLOW good. sorry I don't live close or I'd show you some stuff and help ya out. GOOD LUCK SON. STAY WITH IT !!! NOT A BAD OLE K WHOPPER.
You have to check the hinges on these sometimes they would crack in the 80's we had one that cracked when you raised the cab like this the cab fell forward and hit the ground smashed the viser and windshield
He has a cab jack that has air assist that is not hooked up (notice the extra hose that is not connected). I have the air assist on my 90" cab-this one in the video is 112" cab. Makes for easy lifting. This pump is worn out-should not take so many pumps.
nothing to it right up in the front you have your radiator where the Kenworth big ribbon is you just open it up and there's the radiator cap and the dipstick is right there to you open up the side door and pull it out you can check the oil. you don't have to check the cab up unless it's not running right all you have to do is look right down in between the fuel tanks and the steps.. crawl right under
do any companies run cabovers since the length laws came into effect? I hear drivers refuse to run em, front collision safety? I'm just getting into the business this year, I kinda digg cabovers, innovative and efficient design..pretty standard in Europe..hows driving one compare to a standard? think day to day I'd prefer the cabover for corners traffic etc, your thoughts ? thnx for posting
plane gaper search for european trucks they are cabovers all of them. As for the noise or the heat emitting from the engine dont worry the cab is very good isolated
there's no way in tha' hell I'd do that pumpin to open a goddam hood on nan' truck.. I'm kinda glad they did away wit' deez dinosaurs..it's a cool ass truck and I like em but fuck that pumpin shit.
I know where I can buy one of these old girls. Silver with fatter stacks and a front bumper skimming the ground. Polished aluminum rims twin turbos on a Cat , tinted glass and she is a living doll. Save em boys they are a hoot .
I put air ride on the cab on all6 of mine what a difference in the ride it rode the same if not better than a conventional I put hundreds and hundreds of miles on those old KENWORTH s loved em
Nice I did my fair share of time working on these cabovers in our fleet, it was a good day when I had to raise one of our air over hydraulic international ones, was a factory option push button at jack ran off truck air system as long as you had air in system....
No. All the simple stuff, like oil level and coolant checks can easily be done without raising the cab. On my 1991 Freightliner, there's little flip up doors in the front for all that. Plus, you can do a visual of the engine and so forth by sticking your head up under the front wheel well with the cab down. Raising the cab is for when you have problems or for washing things, especially in winter.
I drove cabover for a year or so when everyone was switching to conventionals. Never had to raise the cab as a driver. There were doors for oil and coolant checks. Raising the cab was a job for mechanics.
I bet there were a lot of cabover drivers who a lot of times forget to secure their stuff inside the cab before taking their semis into the shop to get serviced on & when the mechanic raises up the cab to get to the motor, all of the trucker's stuff inside the cab will get tossed around & break the windshield. Lol
I used to work at a shop where the ceiling was too low to raise the cab. These were always outside in the “big bay” to work on. I was the big bay mechanic.
They have a tube dipstick-you dont have to raise the cab to check oil or water, just major access for repair etc. Notice all the real chrome and real dome lights-when trucks were trucks. Notice the cable shift linkage? Easy to work on trucks.

Why the hell don't you put the camera closer to see how the cabin system does to raise it, it doesn't work for me and after repairing the bonba and the hell it doesn't work either

This is the guy.... this is the guy right here. He knows.
Fluid jacks fail those trucks where accidents waiting to happen.
I thought it was over balance didnt look right
Good catch on the overextension. I was witness once to an overextension where the cab actually broke free and pivoted all the way to the ground
Just a friendly note: that little rubber button to the left of where you stick that jack handle is a button used for operating that little pump by air, if your tanks have air built up, so you don’t have to sit there wearing yourself out pumping it up and down
😂😂
Hope you didn't leave your coffee in there.
I am sure many cups off coffee ended up on the dash and windows of these cab overs. lol
despite there pain in the ass nature I still love cabovers now I may drive a conventional long nose Pete however cabovers will always be my favorite trucks
There is nothing like a cab over u can get into places a long nose will not been there done that.
Reading the comments makes a guy realize how lazy everyone has become It took 5 minutes to raise the entire cab off the frame geez lazy people
I could do it 😀👍 looks fun ! ! !
Nobody wants to spend 5 minutes to raise the cab of a truck just to check something simple like oil or radiator fluid. There's a reason these things are obsolete.
Is definitely worth the 5 minutes. So much space and accessibility to work on it!
@@UltraMagaFan I guess Europe never got the memo.
Great way to wake up yr Co driver
No wonder they did away with these cab-over's... by the time you get the thing raised up and lowered, I would have my entire pre-trip done on a conventional!!
Wow. I always thought those cabs were motorized.
Your jack needs oil
Your hydraulic oil might be low. It's impossible for manufactory to make it this difficult to lift the cab.
pump must be low in fluid.
Need a new jack, I drove those when new, never seen so muck jacking in all my life, a man would be wore out jacking a cab like that.
Needs oil in the jack. it shouldnt take that long to pump it up...
Good point.Also its a good idea once the cab is up to its apex and starts to go over center.Flip the lever to down and feather it till the cylinder hits its end.
No not long at all actually. I got mine up to safety stop level in maybe 45 seconds MAX !!!!!!!!!!!!!! But they were well maintained trucks. This truck -- if you watch a previous video was recovered from A TRUCK GRAVEYARD AFTER YEARS OF NEGLECT !!!! It got HORRIBLY BOGGED during the recovery.
The last time I saw cab over that far it hit the ground not a good idea to go past center just go far enough to get lock in place or it might go over and blow ram seal out
That final tip over would scare the shxt out of me every time lol, wondering if one day it will just fall right off
Better have a clean interior or everything will smash into the windshield
YOUR JACK IS FULL OF AIR OR ITS WORN OUT DUDE
My heart stopped beating at the 3:40 mark.

Really no need to take the cab much further than 40 degrees -----------unless the engine / radiator are coming out. Then safety chains or straps should be used to prevent free fall.
slimchancetoo, been there mate, nearly dropped an engel through the windscreen.
Truck engine maintenance
Hooded: Open hood, do work. close hood
Cab over: remove all loose contents from cab or strap them down, spend 5 minutes jacking up cab, hoping it doesn't fall on you, do work, spend 3 mins putting cab down again, replace cab contents
Hmm, I wonder why hooded trucks are more popular...
Yep -- same with a cabover. Lift it check it drop it.
Must be fun checking oil daily
Oil is usually checked by a dipstick accessible either through the front panel (a little door just below windscreen level) or depending on what manufacture engine, just to the rear of the drivers door. Coolant top up is a pain in the arse unless you have a flexible funnel; but also does not require cab tilt.
Skill comin' handy when a trucker feels lonely on a truck stop
I take it the air assist on the cab raising mechanism does not work. That is what the small almost indiscernible button is for, the one at the side of the pump.

that's what I was weaned on 32 years ago damn good truck
I miss seeing these cabovers on the highways. There are a few farmers here that use them but thats it..
I think an electric motor on that hydraulic pump would be a good investment
Used one off a old switch truck or something could probably even work, that was a little excessive
He's doing it the last resort hard way lol u can do it in a couple of seconds using the trucks air lol as long as it runs anyway
Wondering how is the shift connected to the transmission?
cables
Now all your shit came out of the bunk and flew up against the windshield.
Be thankful the cab jacks up most of them old cabover KWs the dog house was all busted up & if you could get the cab up it would lean so bad you couldn't get it down, kenworth made a repair kit for it
it took about 30 hours to install , A bunch of old trucker guys years ago called them old cabovers front wheel drive , I remember the in the 70s & 80s that's all you seen on the road In the late 80s the length laws
changed by the early 90s the salvage yards were full of cabovers you couldn't give them away they were worth more dead than alive.
Brings back memories of working in a truck shop tilting cabs. That part and the end of the raising procedure, where it falls to rest got me nervous every time! Where is the gear linkage?
That would be cruel trick to play on someone why they sleeping
Yeah lol just imagine waking up to the cab being tilted and u just falling
It must of been quite annoying if you were a full time long haul driver. Everything in the cab would be in the windshield every time you had to crank it up.
I wonder if you can get in and drive it with the cab raised. 😁
Yes you can it's extremely dangerous though
@Andy lol
nice truck but good lord takes a while to raise and lower the hood
On this type of truck it's called the CAB(IN).
I can see why these never caught on as standard
these once were everywhere on the highways
SCREW. THAT. First modification I’d make to that rig would be an electric pump.
They are fitted ex factory with a hydraulic-pneumatic pump which, when properly maintained, will take the cab to an effortless 30% ----- sufficient for routine checks and maintenance.
Lazy this not a phone or a GPS this a man's Truck.
I love it, I never seen this before always wondered… completely awesome thanks for the video
You should put some fluid in that cab jack
Notice to the general public, dont go under any cab over truck when the cab is coming down, dont put your arm under it, dont put your head under it and certainly not your whole body. Should have just said dont try this at home.
lovely old truck from the 80s era they were first class in thier day liked the shape of the cab always did and the CAT engine under the cab was a great engine the 3406 is some engine allways willing to do its best like the Cummins cheers to all you truckers out there god bless
Most beautiful truck ever made, the K-100. You find me another one that even comes close..
What happens to the steering column?
So damn cool. I love big trucks especially older ones. I have 0 desire to ever own or drive one but they are awesome to watch.
Where do you live? Looks awesome
Nice rig. Would love to restore one. KW COE has always been my favorite truck.
There sure are a lot of stupid comments on here.
Looks like your front tire is flat ,,you need more fluid in your pump it will surprise u how quick it goes up if u fill it ,,only about 10 or 15 pumps it will b up
Wow a Transformer! Now you just need an Autobots decal! Lol! Autobots roll out!!! #optimusPrimeVoice
Reminds me of my times in the shower 😉😉😉😉😉😉
The hoses are backwards they need to be switched around that’s why the raise and lower isn’t correct
u need a new pump jack because that's rediculous when I drove a freightliner cabover it was no where near that many cranks lol
that must be a fockin pain if u wanna just simply change a fan belt
looks like a double bunk
sitting down to much. use 11r24.5 tires
3.90 or 4.11 ring gear and pinion (Rockwell's)--40s or 44s
a good single exhaust system is OK. but that split t don't look right ? couple 86200-nelson fully baffled mufflers are quite and FLOW good. sorry I don't live close or I'd show you some stuff and help ya out.
GOOD LUCK SON. STAY WITH IT !!!
NOT A BAD OLE K WHOPPER.

How bout some fluid in the reservoir so it goes up easier/quicker??? welcome to trucking 101
You have to check the hinges on these sometimes they would crack in the 80's we had one that cracked when you raised the cab like this the cab fell forward and hit the ground smashed the viser and windshield

Notice the fluid leaking around the cylinder too.
How you finally get that pencil that rolled under your seat and you just can't reach it.
Only 261 strokes to raise it. 🤯
Dude you look like you live in the middle of farkin nowhere ;;cheers for the vid 👍👍
Reminds me of the Mad Max movies
What’s wrong with living in the middle of Fucking No Where?
At least your not Housing a forklift like the other nut on the other TH-cam thanks for showing other people the right way thanks hemming towing
Some of the best trucks ever made. You definitely don't need to go to the gym after that though.
At 4:20 it looks like he’s depressed
Imagine doing a pre-trip in this........oh the horror!! Lol
nothing to it right up in the front you have your radiator where the Kenworth big ribbon is you just open it up and there's the radiator cap and the dipstick is right there to you open up the side door and pull it out you can check the oil.
you don't have to check the cab up unless it's not running right all you have to do is look right down in between the fuel tanks and the steps.. crawl right under
...there's got to be a better way.... :)
What a pain in the ass, I think I would add an electric pump
They were fitted ex factory with an air over hydraulic pumping system.
That's pretty cool, never thought of ”how the cab is moved ” thanks for showing
do any companies run cabovers since the length laws came into effect? I hear drivers refuse to run em, front collision safety? I'm just getting into the business this year, I kinda digg cabovers, innovative and efficient design..pretty standard in Europe..hows driving one compare to a standard? think day to day I'd prefer the cabover for corners traffic etc, your thoughts ? thnx for posting
I imagine they're really hot cause your practically sitting on the engine.
plane gaper search for european trucks they are cabovers all of them. As for the noise or the heat emitting from the engine dont worry the cab is very good isolated
Question I'm a apprentice at a diesel shop ..what do I need watch for lower the cab ?
The pump and or the rams are worn and maybe a little air in the system too boot. Way too much pumping my arms started hurting just watching this.
there's no way in tha' hell I'd do that pumpin to open a goddam hood on nan' truck.. I'm kinda glad they did away wit' deez dinosaurs..it's a cool ass truck and I like em but fuck that pumpin shit.
I know where I can buy one of these old girls. Silver with fatter stacks and a front bumper skimming the ground. Polished aluminum rims twin turbos on a Cat , tinted glass and she is a living doll. Save em boys they are a hoot .
body excersise ha ha.. mister.muscleman cabover
Cabovers are the coolest
Around 1:35 you look funny how your arm is going up and down so quickly 🤣🤣🤣 Lol but nice my brotha nothing better to see than an Oldschool😎😎
I put air ride on the cab on all6 of mine what a difference in the ride it rode the same if not better than a conventional I put hundreds and hundreds of miles on those old KENWORTH s loved em
This must be Megatron's great grandfather!!
William Funes megaton was created before this truck was ever built, moron!!
Maryann Newcomb The person who can't spell calling someone else a moron, HOW IRONIC!
The pump on Freightliners would pressurize on forward and backward stroke. More volume, less work.
It's big job to raise it up its should be electrically done not Manually
firetrucks use electric hydraulic pumps to lift the cab
Nice I did my fair share of time working on these cabovers in our fleet, it was a good day when I had to raise one of our air over hydraulic international ones, was a factory option push button at jack ran off truck air system as long as you had air in system....
That's allot of work
You really need to add an electric pump for lifting.
Keep the manual for backup, just add a switcher valve.
you might put some oil in the cab jack.... I need to buy this truck from you.
cosprings.craigslist.org/hvo/5828574429.html
redneckman454 I want to buy it
u need to add oil in the hydraulic pump, it should go up in about 20 pumps
Lmao I'm sure drivers pre trip these cabinets once a week or once a month since it's such a work out just to open or raise the cab lmao
Soo drivers would have to do that everyday for their Pre-Trip lol 🤦🏽♂️ daamm
No. All the simple stuff, like oil level and coolant checks can easily be done without raising the cab. On my 1991 Freightliner, there's little flip up doors in the front for all that.

Lol
Yes you are right it happened often.
i like cabovers just not the one with the front wheels all the way in the back where u dont see it
Wow thats a steep angle
3:32 omg, I tought it was going to break
I drove a k100 back in 1992 an it was a big bunk cab an a 3406 cat an it ran great an could pull really well
HAY NUM NUTS.............DONT EVER GET UNDER CAB
Robert Cowan
Hay is for horses........numb nuts.
If it free falls ouch!
Love those cabovers she's a work truck
I used to work at a shop where the ceiling was too low to raise the cab. These were always outside in the “big bay” to work on. I was the big bay mechanic.
I always liked driving those cabover trucks
i got tired watching this
They have a tube dipstick-you dont have to raise the cab to check oil or water, just major access for repair etc. Notice all the real chrome and real dome lights-when trucks were trucks. Notice the cable shift linkage? Easy to work on trucks.
I've got one of these things on the farm. It's a 1980 K100-C with a Cummins 400 Big Cam and 13-speed. Good truck, but it's starting to nickle and dime me to death...
Something you’d wanna sell ?
I love seeing more attention attracted to this topic rather than video games great job!.
U only have to pick it up till the safety LATCH drops in on the drivers side then you can crawl under there and do your work
4:11 "uuuu piece of candy"
Over a week the cab is raised!!
Me gustan los camiones
My arm is tired out after watching that I'll stick to my conventional
Why the hell don't you put the camera closer to see how the cabin system does to raise it, it doesn't work for me and after repairing the bonba and the hell it doesn't work either
You sure gonna build some muscle raising that thing
