Reversing relay for the puff limiter. -

Just curious, what was the fate of the instructor ? I'm guessing it didn't end well for him.
-
Well no, but that's a good one.

If only there was some way to play those couple of notes from Jackass right now

Gives me a kinda good feeling 🤗
-
Probably conicals in it. Just a guess.

IDK that I'd be just running out replacing injectors, but it'd be a likely spot to get more involved with looking for the problem. Then there's the wiring harness, that sometimes doesn't live through it all. Like F said, it can get expensive.
-
Probably injectors. Have they been changed ? Remans often are less than perfect. Leak around the pushrod and adds up after a short time.

Triplex shifting
Mark T replied to skydawg's topic in Antique and Classic Mack Trucks General Discussion
You're not supposed to use any combination other than compound in OD and main in 5th with a double over. It'll go in them, but you're not supposed to use them. IDK might work better for you to try 3rd direct to 4th direct then move the compound to under ??? First second and third are usually easy pezzy....after that, you need to get familiar with the truck. -
Triplex shifting
Mark T replied to skydawg's topic in Antique and Classic Mack Trucks General Discussion
If it's a double over, wouldn't it need to have the compound in overdrive before the main goes in fifth, and forth to fifth in a double over would be a lot less RPM difference than first through forth. (almost like a split in the compound) In reality, 3rd over to fourth under is probably a tiny downshift. Might try third over to fourth direct ? 😳 This is going off forty year old memories, so I might be a little off. -
Connecticut Construction Trucks
Mark T replied to BKrois's topic in Antique and Classic Mack Trucks General Discussion
Is that the same truck, or a different survivor ? -
I don't think one was exactly like the other, more like whatever arrangements they had lead engineers were allowed to compare notes and such. (like James mentioned) From what I understand it all started with Mack info shared about busses. Whatever , there's a long relationship they had.

It might be cheaper to smoke pot.

I think the Scania / Mack V8 was more about the mighty E9.
-
It's an interesting history. I think many guys might be surprised the extent of it.

I'm in Connecticut several times a week. It's over in the Canaan area though.

Former Boston FD , B85F-1211 project, Mack Brothers....
Mark T replied to T-Mack1's topic in Fire Apparatus
Ahhh . I've noticed fire trucks often have components a little different than other trucks. Didn't know about this one either until you explained. TY -
We could still go eat steak. Pretty hard to get sued for that
-
Mech..... if we could only go help this guy out, then go to Texas Roadhouse

At the risk of sounding dumb, what is the rectifier for ? -
The more I read all this, the more it seems like brake chambers on thee trailer ( and a couple other things that may need attention ) I'd bet if those chambers were removed and shaken you'd hear spring rattle'n around in at least two....which leads to all sorts of fun stuff.
-
That would most likely be a leak in the service side. (still needs to be addressed) Wouldn't have much effect on the red knob symptom. You'd need to chock the wheels. Then make sure the wheels are cholked, then push the red one in and look (or listen) for air leaks in the trailer.

Look on the bright side Bob,you would have never had so much fun driving trucks .
