Many years ago i did the same job on a fleet of brick delivery trucks, one every day for a week.I was nearly a broken man by the end, very heavy work.
That's hard work. Hope you at least get to drive one. It's rough when some guys keep breaking them and other guys fix them.
I hope you have recovered.
Spring shop veteran, can confirm this is easier than servicing Hendrickson walking beams. Riding the camel is easy.
U lost your mind lol
Was a mechanic at a Mack Truck dealership and did lots of these. Often times depending on how many leafs were broke you'd cut the U-Bolts, unstack the leafs and replace the individual leafs that were broken. On the whole spring replacement I had an adapter made up that I bolted to a transmission jack, that threaded onto the center bolt, and could wheel the old spring assembly off and the newly assembled spring on. The U-Bolts on these were the largest fastener on a Mack. Worst part was always spinning the cut U-Bolts out, they were often frozen up in the saddles.
Could you tell me what that parts called ? My tires aren’t really lining up so I guess in will be needed a trunnion or something
@@corybowen1923 Did you measure the centers from axel flange to axel flange? How much is the difference between the right side and left side?
Worked on many Mack suspensions 44 and 55 heavy dirty work, we had a pit to work in which made things a little easier. One guy would hold bushing box over his head while standing in the pit while the other started the bolts Boy o Boy that was heavy work. We also used a chain fall to pick truck up to remove tires and set it down on wooden blocks.
I have seen heavy duty jobs and if I was doing it the thing I wouldn't enjoy is dealing with the grease
You are a hard working man. I always called that Bullwork. Nice setup that Mack uses for their springs. Not like that old school walking beam suspension that doesn't seem to keep wheels on track going around a corner once they get some use. Nice video
Ommm
You made that look easy....its been a long time since I've seen a camelback
Break....he must have felt that hit for a while after
i did these on rear loader mack garbage trucks, getting the cap to line up and getting the two threaded bolts in and the other 2 nut and bolt assembly and getting the caps on properly with the bushings was an absolute nightmare.
Awesome Mack video - thanks. That's a lot of work.
Maybe add another handle on that spanner wrench so you can use 2 hands?
That looks like a Hoyer lift you're handling the springs with.
The CP impact seems like it needs a hug.
another great video! i appreciate you share your skill. I learn so much from your video to do my job better. Thank you
Man that’s a hell of a lot of work! Great job 👏😎👍
I was hoping you would video taking those studs out. For someone who doesn't live in the rust belt I learn a lot seeing all the tricks you guys have
I worked at the Indianapolis Mack dealership for 19 years and did several of these. Including the rubber bushed two piece trunnion saddles.
I still have all my fingers and toes. Two of my coworkers unfortunately don't.
It's a physically hard, dangerous, dirty and time consuming job.
That was in the 80s and 90s I'm paying the price physically for it now.
If I remember correctly the U-bolts torque was 1100 to 1200 pounds.
Rough way to make a living.
Man I still can’t get over that spring hoist. All the dumb ass times I had to man handle them in.
I hear you. Back in the late 70's I had an F Model with the same suspension. Broke one of the leafs and decided to fix it myself because I was a cheap OO. Two days later I got it put back together enough to get it to my local Mack shop where they could finish or, should I say fix, what I started.
I've done plenty of those ,I enjoy your channel
Good job you have those air tools ..a gym membership is probably needed as well .👍👍👍👍
after watching the Pakistani do it with what ever means they have, this is a nice change of pace
For real!
The pakistani guys even work with sandals
You know someone earning their pay when the compressor can’t keep up.
or maybe they need a bigger tank
Lol my husband been watching your work since the beginning and always joked about you getting a Camelback suspension in on the channel
Brilliant video thank you
Un trabajo sencillo y divertido, nada fuera de lo común, es pesado pero con la ayuda de la herramienta se facilita. Cómo sugerencia ojalá mejores tu hábito de trabajo y marqués una diferencia con la competencia. Por lo menos limpia el polvo del área de trabajo descubierta, me refiero al chassis, los tambores de los frenos y todo lo que quedó descubierto al desarmarlo, el cliente lo agradecería y marcaría una gran diferencia con la competencia de otros talleres... Ni pensar en estética estás lejos de éso, pero dime cuándo se volverá a tener la oportunidad de limpiar esa área de trabajo. Así son todos los mecánicos en todas partes solo se limitan a cambiar y reparar pero la limpieza y estética? Se que no es tu obligación pero es el plus del trabajo realizado. Yo lo hago con los cambios de frenos, aseo y repintó. Se invierte un poco más de tiempo pero los clientes regresan y recomiendan. Saludos.
Thank you for sharing your skills...I’m new to the trade...just found your channel and you do good work...by chance would you mind sharing the Dimensions of the tool you press king pins in and out with regardless thank you again for you time and wisdom
Nice job i really enjoyed it ☺️😊
Brilliant mechanic
A pressure clean and a bit of WD40 would have mde that job a lot easier!
Reminds me of the time I blew the left side trunion to bits on a Mack 6 rod. That was fun.
Great video.
Отличная работа ! Приятно смотреть !
Хуйня, чо в падлу ведешкой пролить болты шпильки!!!?
О пролил😁
В Пакистане дешевле и вдвое быстрее сделали бы
Boy if that last spring leaf had broken that driver would have had a bad day. Ol Mack camel back suspensions. They are tough as nails but ride like a two horse wagon. Need to get you one of those big one inch mega torque impact guns to take that stuff off with. Did you replace the bar and do those spring packs come as a unit or do you rebuild them in your shop. Think I would weld an extension on that spanner wrench for more leverage. I like the cart you remove and replace the spring packs with. Is it shop built. Sorry for all the questions but I find your videos informative. They answer a lot of questions and I just like making broken worn out stuff new again. Go buy yourself a beer you have earned it. That is hard work...
its suprising that works honestly
Excellent
Semi Workin,
Mack Trucks are ALOT of work to keep maintained and worked on. Just like the compressed spring assembly ta trunnion with the upper and lower spring pads. (elephant ear rubbers and caps)
Keep it Right and Tight, that's how ya make it happen.
Thank God for compressed air. And impacts.
Crazy when I watch the road side mechanics over in Pakistan do it all with hand wrenches.
Congratulation brother.
need to run tap through the standard threads in housing and make sure they are clean before installing new bolts.
Always.
Qe buena herramienta. Tienes felicidades
師傅你呢一枝風咆都幾好力喎，可以一次過折哂D羅絲👍
Got 4 of those trucks can only get 100000 miles before I have to cut the u bolts and replace the trunnions. Which they would make thicker bushings.
Need to use a better grease or grease it daily
What is the application?
@@jcurtis4082 roll off trucks
@@bigmurph1447 grease them each week when I grease the roll off hoist.
@@wth82 try a high moly grease
You should wear mechanics gloves to remove some vibration from your hands. The rubber cover on your impact gun helps too.
the guy knows his shtuff.been doing it for about 9,000 years.
And doesn't bother to clean or use lubricant until he runs through a tank of air for one bolt, and no torque wrench in sight for assembly... ok
If any manufacturer wanna torture test their impact wrenches hand it over to this guy.
Did that on my 64 B73 about 30 years ago.
Явно не Пакистан ! Дюже чисто на рабочем месте ! И много техники и приспособлений !
good job. your work is similar to mine .
You need a more powerful impact. I know those bolts are tight but damn 8 minutes to pull off the wheels
Trucks are an entirely different thing than cars and light trucks (heavy cars). 3/4" and 1" drive sockets, hammers to turn bolts, wow.
WOW a little lube finally. always helps
Id love to know how you tightenes the ubolt nuts. I replaced the springs on a rubber bush version. Never got the nuts to tighten all the way
Love your videos! Don't you have a 1" air gun for lug nuts?
Never mind, I just got to the part where you took the other side off and you do have one.
Резьбу надо почистить , побрызгать вд , потом откручивать крутя ганом в лево , право
Какое бля ВД, у них перчаток нет, даже у сварщиков, режет металл резаком в сандалях, да пиздец....
just imagine what a terrible world it would be without pneumatic impact wrenches
10 foot cheater bars were common
Oh golly
Those thick springs make good knives and center punches.
Fkin axe it makes.
If my spring are good can I just replace the pads?
What is the tool you used to removed the springs off the trunnion? Need one for our shop.
1:10 Shoulda cleaned the lug threads first. Now you're spinning off the nuts and accumulating a bunch of debris in the threads which will lead to galling.
Absolutely. I worked on GE steam turbine/generators and cleanliness was required, no matter how big or small the part. Components go back together when all machined fits are clean. Couldn't stand and wouldn't put up with sloppy work if it was in my power to control. Contractor millwrights were something else.
Watching this like re-living a nightmare. Old lady told myself i be working on them Tks in my sleep. Moved on to Caterpiller equipment. Didnt have many nightmares or 18 hour shifts.
You have to have driven over some serious terrain to break one of those Camels backs
Those rough riding camelback trucks can sure get along off road. Air ride truck will be spinning on uneven terrain. Camelback just rolls right on by.
A few minutes with a wire brush and some WD 40 would have made this job a lot easier, and 18 minutes watching wheel removal and replacement can get a bit boring, especially when the fitter cannot be bothered to aline the tyre valves properly on the double wheels.
No, in fact, not just a normal no but a h311 no. If I never do one again, it'll be to soon.
Next time when the bolts stop coming out reverse it back up then back it out.
Thank God for impact wrenches 👍🏿👍🏿I could magine the pure hell with hand tools🤬
First I recall seeing a grease fitting for bushing on camelback suspension?
拆車呔不是用1吋的風砲嗎？拆呔快捷妥當。
At 50.05 it looks like you split the part where the threads are. You can see a crack open up the tighter you go with the bolt.
good eye
Cuantas veces lo cargaron cn sobre peso ? Esa ganancia fue para esa reparacion con repuestos. Saludos
Wait a minute this is no Pakistani trucker...I was waiting for him to DIY rebuild from scratch sh*t
Red grease on the screws or is ist anti seize paste?
Did you build the hoist you use
Hey you decided to spray lube them bolts.
Great job but you cracked a insulator cup . Those neoprene does that to cups alot. They do last much longer
Mack camel back or homemade beefed up type is only thing we found could with stand the mt's, dirt, muddy, snowy completely off road . I try grease them walking beam bushing for 8 months twice a shift trying make them last longer. Nope wasted my time 8 to 10 months at best start replace all bushings again. We even put a set-up of full oil covered 90 weight oil in few to test trucks to try it. Not much improvement for the headache of homemade set-up. I could killed 2 drivers every weekend replacing 4 springs, 2 same trucks. Blame in-laws of owners.
welcome to back breaker
What weight capacity were these axles/springs?
👍👍👍👍
👍👍👍
Hello guys, where can I buy that piece that was replaced?
Man ,is that on a mixer ,I've never seen a camel back break like that
What's that one little weird locking bolt do and what does it thread into?
You mean at the 30m mark?
@@christopheryoung826 yeah I should have mentioned the time.
@@rtz549 if you mean the nut he screwed on then put a bolt onto it holds tension of the spring to the rod that goes across to the other spring. I cant remember the name but ill look it up for ya after work
At 27:40 he puts on a metal ring with holes in it. That little bolt threads into the collar nut and sticks in one of the holes to stop the collar nut from backing off.
👍👌👍
Good god I hope that was red never seize and not lock tight on those basket bolts 😂. I work on a few of these a week.
Where's your shop located?
What is that set called ? I wanna go to Mack I just don’t know what is called or do you have a part number
@11:00 I think that needs a gallon of WD40 right there.
I think I'd of pressure washed that stuff first
Amen. And some penetrating fluid wouldn't have hurt.
這個拆卸螺絲的工具也太小了吧？即沒效率工具也容易損壞。
🤩🥰🤩
A pair work gloves will make a lot easier and safe
Làm xe to mà cái súng nhỏ quá
Шпильки помыть и щеткой почистить не судьба,проще стоять и мучаться.
La pistola es muy chica para ése trabajo.
Me refiero al sacar las llantas.
What would you charge for this job in today's time
Somebody needs more air compressor tank capacity
neverending fight, got bigger compressor, buying bigger tools .. battery tools catching up quickly
I have changed many of those.
I don't envy anyone changing camelback springs.
Where is your shop ....we can get u lots of business we in chicago
почистить резьбу перед откручиванием...не, не слышал...
посмотришь даже с перемотками это видео и понимаешь, что такого криворукого мастера еще не видел...
Carried to many straws again?
Its funny on how you record things just fully concentrate on bolt things up, not the actual preparation
they call them camelback because that's how your spine looks after riding in one of these.
Que tipo de hules son esos
