  1. You sure this doesn't belong in the "you might be..." thread???
  2. Here in NC, we have class A, B, & C licenses...in both commercial and "civilian" forms. Sounds similar in SC.
  3. True. Some states have air brake rules. Some don't. Gotta keep it confusing, otherwise there is no money in it for the states!
  4. Yes, even a commercial vehicle less than 26,001# can be operated without a CDL. That's because so many "commercial" vehicles are actually pickup trucks, cars, and such. So, there is an exemption for those lighter weights. 26,001# and over requires appropriate class A or B CDL IF used to generate revenue. If not used to used to generate revenue, there are non-commercial class A and B licenses available (at least in some states). And, a CDL can be used in place of a "civilian" license.
  5. So, did you essentially wind up with a non-commercial class A, or is it still commercial and just can't be used commercially?
  6. "If you've used a "No Fishing" sign as a rod holder..."
  7. They loved their inertia starters! Nothing like that sound, is there?
  8. According to the folks in the plant, these were made for Mack. Not sure if that was a 1-time thing, an ongoing order, or what.
  9. I know that "Mack" rears HAVE been made by other people than Mack. Not sure what years, though. A few years ago, we were in a Meritor (formerly Rockwell) plant, and they had "Mack" rears, which Meritor had made there, stacked to the ceiling. Contract work, I suppose. Again, not sure if that happened that long ago.
  10. Mine came with QR valves factory. It did not come with relay valves.
  11. Parking Brake Valve with Anti-Compounding Function (one way to do it, anyhow). PP-2.pdf Pretty sure this was it...
  12. I have schematics for the later (R) brake plumbing. But, I saw a link to this site that had schematics from people who had already converted their Bs to spring brakes. So, you should have plenty of information at your disposal. The air systems really are not all that complicated once you understand what is being done. You shouldn't have any issues getting it plumbed in and working the way you want. Here is a link to one of them. A Google search will show you others. One think I do encourage in a spring brake setup is the use of an anti-compounding valve to keep from applying the service brake and parking brake at the same time. The way mine was done from the factory was really simple and did not require a separate valve. Mack used a specific push-pull valve for the parking brake which had the exhaust side plumbed in by a small line to the service brakes. This way, if you applied service brakes, that pressure went into the release side of the parking brake and negated some of the spring force. Voila! Anti-compounding! Then, when the parking brakes were released, the exhaust port was closed and the service brakes worked normally.
