Wrong trunion stand and axle caps for anything 58k or larger.  A solid beam was an option for all camelback suspensions.  

One of the downsides of a big v8 is that all the plumbing and wiring gets tossed on top of the engine. Mack just put it in the easiest place I guess.

I'm not from New York and thus have never paid attention to him. But his performance in these press meetings by any stretch is impressive.

 I'm not up on Cuomo's stance.....on anything

So if I’m reading this correct you are ready to nominate this guy for president with out knowing anything about him other than he can b.s. his way through some press conferences.  I’m gonna go out on a limb and say we are drastically different when it comes to politics. 

Im from NJ so I get a front row seat to these Democrat governors trampling on our rights.  

I’m curious for more information on these.  I can’t seem to find any other info online.  
 I have a set that’s going under the rd800 but they are about 25 years older.  

 

For a few years now new trucks can come from the factory with yokes that are not lined up (out of phase).   This is normal and engineered with regard to which suspension is on the truck to cancel our vibrations.  It’s mostly on the shaft between drives.  It is even more important now to mark the shafts when servicing. 

Judging by the wedge brakes and no planetary hubs I’ll say it’s a sw80 suspension. 

Let me know which ones you end up needing.  I have a whole pallet of good take off Jakes.  

You can try Jimmy over in PA.  He has a lot of stuff but he is not always the cheapest on price.  Sometimes he doesn't like to remove 1 hub if it’s still on an axle.

Big Dawg with an E9!  The RD822 was produced between 1982-1990 with 233 units built.

This truck was very well done. A lot of time and money to get it looking like that. 

That was an interesting truck.  The guy that was working there said he thought the truck was heading to Colorado.

 I’ve seen some home built transfer case mounts that are pretty scary.  The mount in that truck looked beautiful.  Factory looking I guess... lol 

Top notch photos!  There were some really beautiful trucks at the show.  

I’ve been following the progress for a few years and was so excited to see its maiden voyage.  Now I just need to talk the wife into going out west for a train ride....

I’m looking for a 65k cutoff on beams.   If anybody has one let me know.  Thanks! 

That’s what I was looking for.  Thanks so much! I purchased a RD822sx and couldn't remember the frame options. 

I remember someone had posted a chart that had various Mack models and the frame options and RBM rating. I can’t seem to find it again.  Anybody have a link to it by chance?  

I get this complaint all the time at the shop.  Typically seized anchor pins are the culprit.  Anything that is putting resistance on the brake shoe from freely moving can cause this issue. In my experience rarely is the brake chamber at fault for this complaint.  

Back off the slack, remove the drum and remove the main spring.  Try to swing the shoes over center.  The shoes should swing smoothly with little resistance and the anchor pins should rotate in the bushings. 

Even though brake shoe kits come with new anchor pins/bushings seems like most shops just throw them in the scrap pile cause they don’t want to spend the time to replace them.

Not at my fingertips, no. Mack engineering explained this to me years ago.

I can’t help but laugh.  Your telling me I’m wrong and your reasoning is because ‘a guy told you so years ago.’  It fits very well with the last post about “not believing everything you read.” 

I’m just trying to get the correct information out there.  There are people here that are looking for an answer (me included) and I’d hate to see bad information be spread.

Produced by Wagner for Mack, they have significantly more force, a requirement for a 20k axle versus a 12k axle.

That Volvo wants to charge you $744.85 for a $200 component should be a crime.

Volvo doesn't want you operating a 1996 vintage truck. And they want to rinse their hands of "American" Macks.

Do you have any information on this?  I disagree with parts of this statement. A type 30 roto-chamber has the same force as a standard type 30 brake chamber.  Area of diaphragm in sq/in times pressure.  I was under the impression the main reason behind roto chambers is packaging.  Roto chambers use an elongated diaphragm which “rolls” on its self while traveling the length of its stroke. This allows a smaller overall diameter while still having a large surface are of the diaphragm. 

Now back to your statement, they may have more force for use on heavier axles but not do to it being a stronger chamber.  It’s due to the fact that you can fit a type 36 or 50 chamber on the steer.  

To sum it up a t30 roto has the same force as a t30 standard. A t36 roto has the same force as a t36 standard.  It’s physical size that is the difference. 

They are not not the best pictures but it gives you an idea.  The y-pipe is under the cab and the stack mounts are identical on both sides.
