I can attest to how heavy the camelback springs are. My dad and his brothers had a trucking company and they only used Mack R-600's. Around 1977 or 1978 when I was 5 or 6 years old they had two camelback springs sitting on an old warehouse cart in the shop. The cart had two wheels at the back and two stands at the front to hold it up. You backed a two wheel dolly under the front and then pushed the dolly handle down to raise the cart off it's stands. While holding onto the handle you could then pull the cart around the shop. I found a dolly and managed to lift the front of the cart and started pulling the cart and springs around the shop (the total weight was probably 1000 lbs, I was pretty strong for my age). I pulled the cart around for a while until I got tired. One of my dad's drivers then helped me lower the cart as the handle on the dolly had a nasty habit of flying up very fast as you lowered it. For my size it would have delivered a frightful upper cut to my chin. To me this was a completely normal thing to do. Today a fully grown man would probably be required to take several hours of dolly/cart safety training before being allowed to do what I did. All I got was my dad saying "don't let that fucking handle hit you in the chin". Ken

I remember a mate, from the 1970's, purchased a G88 Volvo. First thing that he done was to remove the Volvo 6 rod, and put a Mack Camelback under the back end. He went from a 180 International towing 2 20 foot single axle trailers on a single axle dolly, to this truck with a tandem drop deck and a 444 international, reversed steered, with a Robot brand mast on it, for brick cartage. The tractor was a lot of fun to operate!!! Sadly, the tractor was lost in a bushfire in January 2020.

Yep, Chicago Pneumatic's line of impacts go up to 2-1/2" Anvils (CP6240-T120). At that torque level (and weight) though, you need two handles (and 75CFM of air). It weighs about 132 lbs with a maximum reverse torque of around 18,440 Ft-lbs. The modern equivalent for what sir is using in the video looks like a CP6120-D35H 1-1/2" Anvil Impact with a maximum reverse torque of 3500 ft-lbs. It weighs about 35 lbs. Today they go for around 4-6,000 US dollars and need 52 CFM at 90PSI to be driven correctly.

Cut out the stands and put in one that you install from underneath. Not really sure how I feel about the design but the stand was definitely more stout than the older ones.

Does it extend the life of the leaf springs to have lubricant between the leaf springs?

I’ve done quite a few camelback spring jobs. I always changed the entire pack as just changing failed leaves usually resulted in the other old leaves failing later. Not a hard job with all the right tools, but a brutal job to have to do out in the bush and torquing the u- bolts by hand with a monster sized snipe. I also did numerous centre pivot bushings and end pads on the lighter camelback suspensions and would do a 38000 or 40000 pound bushing job over a 44000 pound or heavier suspension bushing job.

Hey if you are short a leaf do what they do in Pakistan. Weld it back together, grind it a bit, soak it in some salt to put a little aging rust on it, and send it out the door. Don't worry about heat treating as it won't last much more than a mile anyway, but the customer will just think it is a new break and bring it back for another repair. Win/win. 😁

As a self-taught hobbyist mechanic, I've always wondered, when disassembled, if putting some type of thin film of wheel bearing grease or graphite between the spring suspension leaves of a truck would make the ride smoother or less harsh? There is no inter-leaf friction with a coil spring and the shock absorber handles the suspension compression/rebound just fine.

back in the 1930s they actually painted the leaf springs with grease and wrapped them in canvas cloth. It worked fairly well back then, however they now use a different type of steel 5160 and you should keep the dry. getting oil or grease on the steel will actually decrease the life expectancy and ruin the steel.
