Mack Camelback Suspension | Rear Spring Replacement

[@JohnSmith-uk1vb]

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.

[@randallyarborough7923]

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

[@01crazycooter]

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.

[@corybowen1923]

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

[@01crazycooter]

@@corybowen1923 Did you measure the centers from axel flange to axel flange? How much is the difference between the right side and left side?

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.

[@nickrexroth2785]

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.

[@chucktaylor4958]

I hope you have recovered.

[@gabelanger]

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.

[@kmuinde]

I have seen heavy duty jobs and if I was doing it the thing I wouldn't enjoy is dealing with the grease

[@harveybirdman7507]

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.

[@melvinschmecklebak3766]

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

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

[@johnz8210]

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.

Crazy when I watch the road side mechanics over in Pakistan do it all with hand wrenches.

[@saraloy8926]

Lol my husband been watching your work since the beginning and always joked about you getting a Camelback suspension in on the channel

[@hddm3]

Man I still can’t get over that spring hoist. All the dumb ass times I had to man handle them in.

[@Tom-In-Ga]

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.

[@lad6051]

A pressure clean and a bit of WD40 would have mde that job a lot easier!

[@mybestieischloer2401]

the guy knows his shtuff.been doing it for about 9,000 years.

[@ncd9656]

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

[@bill154cub]

You should wear mechanics gloves to remove some vibration from your hands. The rubber cover on your impact gun helps too.

[@lioneljosecastillo]

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

[@leonardoflores9306]

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.

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.

[@Jkush463]

its suprising that works honestly

[@daveA2024]

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.

[@angelinaduran3455]

Qe buena herramienta. Tienes felicidades

[@airdave1961]

WOW a little lube finally. always helps

[@johnnyholland8765]

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...

[@brentsmith5647]

Brilliant video thank you

[@fredsalter1915]

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.

[@ojofelixnm3608]

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.

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.
