New and need some help

I'm totally new to the truck world, I know a couple things here and there but I'm not good with all the lingo. I have a 94(built in 93 so I'm not sure if this is the right place to post this) Ram 2500 5.9 turbo diesel 6 cylinder in line. It's only got about 226k miles on it, bit they were some pretty hard miles. I recently had to replace the gearbox and it was a painful experience (money wise) and I'm hoping I can get some help so I don't have to go through that again.

The problem started yesterday as I was on the highway, I stopped on the side as I noticed my hood wasn't closed all the way and when the truck came to a stop I could smell burning rubber. I got outside and could clearly hear a rubbing noise coming from under the hood, I look and it appeared to be done to do with the belt. I closed the hood and hoped I would make it home, and it didn't seem to cause any severe problems the rest of the trip. I could still smell the burning rubber the entire trip but I didn't do anything further with the truck. The next day I had the hood popped and tried to crank it when it failed, it turned over a bit but didn't start. I tried it again and it started, but I could immediately smell the same burning rubber from before. I looked a bit closer and it was making a pretty bad rubbing sound from the crankshaft (?). I have a couple of thoughts myself but wanted the opinion of someone who knew more about it than me. If you have any questions or want a video just ask and I can send one.

Thanks,
Mauz

No smoke or fire under the hood, just a bit more smoke coming out of the exhaust. I took a quick vid: https://youtu.be/nQBE3FjE3Qo

I suggest you start it again, let it run for a couple minutes, then check all the pulley wheels for heat. The AC compressor, idler, water pump, fan bearing and alternator. If none of them are hot then remove the belt and spin them all by hand. One of the above is probably failing. Also check the damper for serviceability. Inspection criteria is in the FSM.

Is it a rattling noise? Possibly check the valve covers’ long cover plate. I couldn’t hear anything out of the ordinary other than a possible vibrating rattle. As for the burning rubber smell I can’t help you there

Could make it out, sounds like it's coming from the ac compressor.

Unplug the wires for the A/C compressor clutch and see if it goes away.

That wouldn't rule it out. Turning off the AC would provide the same results.

Yeah if it is the Ac compressor, it would likely be the bearing within the magnetic clutch, what spins regardless if the ac is on.

I ended up taking it to the shop for a diagnostic, the ac compressor was fried. Unplugged it from the electrical and it was fine, just have no AC. I also replaced the belt later on and put it in the no AC position so it's fine for now, thanks man

It was the AC compressor, it got fried. The vales and such were ok, I just ended up unplugging the compressor from the electrical and switched the belt to no AC
