You can do that but the two bottom plates you have should cover the spread between the hangers.

What's the reasoning for ditching air ride? I'd have switched over to Neway over the spring ride.

Have you considered flux-cored wire..? No shielding gas required AFAIK. Maybe Welder Dave could advise.

IMHO the words air ride and dump truck should never appear in the same sentence.

There is someone who thinks like I do when it come to this topic.

Thats all pretty much designed to go inside the frame rails. I layed this all out before i got the info on frame width. Its been hard as hell getting goid info. All the old knowledge is gone! I guess I could go that route but then id need some spacer plates for the cross member. Either way im gona have to have some more pieces made.

I do alot of off road work and the air bags just dont articulate well. That freightliner 4 bag is the worst system I have ever seen. Its constantly broke or loose u bolts. Seems like all ya do is work on it and its pretty rough ridding for what it is. I have run hendrickson before in other trucks and its just more duty rated for the type of work I do. The only airbag setup I ever liked is the kenworth 8 bag. And even it has its off-road limitations!

I really dont like flux core at all! I dont have much experiance with it but from what little I do have it's about impossible to get a good looking bead. Im sure there are certian flux core wires that are good for structural applications but I just dont know enough about it to be comfertable with it on a super critical part like these axle brackets!

Why's that? If you have air ride on the dump truck it's sure to dump! Maybe to the right or the left or once in a while out the back. Very adaptable, puts the load where the ground is the lowest.

That's what I explained above, a spacer at bottom of crossmember.

I wonder if any truck salesman has ever used this pitch? Na, That would be the truth. Not allowed.

Tri-mix shielding gas is generally for Mig welding stainless steel. There are probably some specialty applications that specify tri-mix gas. Assuming the frame is mild steel or higher strength weldable steel (some frames are heat treated and require specialty welding procedures or welding is not recommended) ER70S-6 is equivalent to 7018. There are no issues with overheating the steel from multiple passes. CO2 has more penetration than a mix gas for Mig welding but has more spatter and not as nice of looking bead as argon CO2. Either stick or Mig would work but should be done up-hand for maximum strength. Flux-core comes in 2 versions, gas shielded and self shielded. Self shielded isn't as common and I don't think you want to buy a roll of the proper wire just to do one job. Gas shielded flux-core is very common and depending on the specific wire could use straight CO2 or argon CO2 mix. Smaller wires generally use a mix gas as it gives better control over the puddle when welding out of position. Again any vertical welding should be done up-hand. If you're comfortable running 7018 just run 3/32" up-hand. I think for 3/8" plate I'd just run 1 pass and should be able to do a nice weld. If you don't quite have a 3/8" fillet I don't think will make much difference as long as the weld is sound. If it takes a little longer who cares if it's your own project.

That's all great info! I am not an educated welder but have developed pretty good skill at it just by necessity LOL. Any knowledge and advice from a real Pro is always good! 7018 is about the only Rod I will run. For this project the only welding I have at the moment is welding the axle brackets on the axle tube! I'm not changing anything on the frame itself that is requiring welding. I do always run 7018 uphill. I do prefer to run wire downhill I guess I haven't ever tried that uphill.

Got one axle sandblasted and painted today. Was going to do the other one but then got a call to run to Tulsa. That pretty well wiped out the rest of the day! The weather is supposed to be really nice this weekend. Should get a good chance to catch up on all my sandblasting and painting.

In my working life I operated, a small fleet of dump trucks doing logging road construction on Vancouver Island. I had three different makes of suspension, Mack camel back, Hendrickson RT, and Pete Air trac. The trucks were always overloaded and very tight turn arounds while loaded and soft ground. The Hendrickson took more maintenance than the rest, broken spring eyes, broken springs, spring hangers. If you tried two transverse torque arms axles would not articulate very much, then reverse traction was terrible, so we only ran one on the rear axle. Camelback was very good traction and very little maintenance, and to my amazement the air trac was the best traction qnd least maintenance. When the PTO was engaged the air bags dumped.

I have sandblasted several of them over the years and haven't had one leak yet. I always wrap that area with a rubberized tape made for sandblasting. Also remove the vent and put a steel plug in. There is some prep work to do before one goes to blasting.

I can't imagine why you had so much trouble with the Hendrix set up. My experience has been quite the opposite with the Peterbilt suspension being the absolute worst second to the Freightliner. I never have had a Mack Camelback but they look to be a very Hardy suspension. I have seen truck setup with the PTO on the airbags dump kind of a way to make it idiot-proof for-hire drivers LOL. When I set this truck up I put in an alarm system that an alarm chimes and a light on the dash flashes anytime the truck is not in a going down the road configuration such as airbags deflated, p t o in, in reverse gear with drop axle down, tailgate open and differential lock on. Again all to idiot-proof for-hire drivers

Hated flux core, loved dual shield. Most everything on heavy equipment was done with dual shield at the dealer level. Used a lot of hard wire on thin stuff.
I have some experience with the old standard suspensions, but now I'm seeing Chalmers suspensions on dump trucks and heavy haulers. Any comments on that stuff?
