mowerman Posted November 22, 2022 Share Posted November 22, 2022 I like the air start part. They’re pretty efficient once you get them dialed in but yes, they can be a pain in the ass if you don’t keep up on them.Bob 1 Quote Link to comment Share on other sites More sharing options...
Freightrain Posted November 22, 2022 Share Posted November 22, 2022 The 673T is just 205 hp. The ENDTC is 250 hp. Neither have intercoolers. Non turbo 673 is 170-185 hp depending on which intake it has. Bobtailing you won't really notice much. My old 673 with no turbo would scoot along quite well. 2 Quote Larry 1959 B61 Liv'n Large......................

Bob If you leave the twin disc clutch? Mine had single disc, so it bolted right in. 1 Quote Larry 1959 B61 Liv'n Large......................

Has wedge brakes though and my single axle has maxi’s so not sure what to do yet. Quote Link to comment Share on other sites More sharing options...

Sure is a big difference from Armstrong steering. Felt like modern truck steering 1 Quote Link to comment Share on other sites More sharing options...
Joey Mack Posted November 22, 2022 Share Posted November 22, 2022 I do beleive the bolt pattern for wedge brake spider and the s-cam spider is the same.. I assume the same style Mack rear's on both truck's? 1 Quote Link to comment Share on other sites More sharing options...

I assume the same style Mack rear's on both truck's? Oh that’s good to know! No, they’re different style. The single axle looks like a more modern setup, I believe with camelback suspension. The dual axle has the rear ends that look like they’re flipped on their side, if that makes sense? Quote Link to comment Share on other sites More sharing options...
Joey Mack Posted November 22, 2022 Share Posted November 22, 2022 (edited) that picture shows Mack rears. they are top loaders.. whats in the other truck? I would like to see a picture of a single axle camel back.. never heard of one.. the truck pic you posted is camelback.. I guess that the new truck?

Joey Mack Posted November 22, 2022 Share Posted November 22, 2022 can you raise the bodies and post pics of the brake chambers? wedge brakes had lateral chambers and s-cam brakes have longitudinaly mounted chambers.. Of course,, I am always eager to learn something even if I need to be corrected.. jojo Quote Link to comment Share on other sites More sharing options...

It has its quirks, but overall it is fine. Like air starter, you have to maintain it to a degree or it will cause grief. I put air start on mine also. New valves, new lines. Works like a charm and holds air for 6 months without a problem. Quote Larry 1959 B61 Liv'n Large......................

I just saw big springs on the green one and thought camel back. I’ll get a good pic of it tomorrow at work. The rear on the green has “Mack” cast into the pumpkin on the back. This is the only pic I have of it right now Quote Link to comment Share on other sites More sharing options...
mechohaulic Posted November 22, 2022 Share Posted November 22, 2022 when the air assist starts acting up like not so smooth , the cyl on tie rod usually develops a groove mid way. wedge brakes are like everything else;; great when working right: real pain in a-- when time for repair/ replace. have changed a couple from wedge to cam. most times owner was better off finding another donor. swapping entire assemblies. 1 Quote Link to comment Share on other sites More sharing options...

I guess I don’t really know if it has wedge brakes. I just saw these tiny little cans underneath and just made an assumption. I’ll get the body up and get some good pics Quote Link to comment Share on other sites More sharing options...

This is good to know. It seems ok but I only drove it around the pit for a bit. I’ll have to drive it around a bit when I get it back to work. I guess I’m not really sure I even have wedge brakes.
