    Looks like 4 cranes.

    This truck was working in Pennsylvania not very long ago. I wanna say a woman drove it.

    Looks like maybe someone tapped into the same fitting on the manifold for a manifold pressure gauge (?) . Try explaining that leak to a DOT guy in 2025 🤔

    There's a couple different types
  5. Mark T
    Yes

    And then there was that Hanson fella......

    It gets air when you release the parking brakes, then meters air to the puff limiter on the injection pump in relation to manifold pressure.

    I think there's a story about that too. Like Diamond T made the Jrs

    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.

    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.
  17. Mark T
    Probably injectors. Have they been changed ? Remans often are less than perfect. Leak around the pushrod and adds up after a short time.

    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.
  19. Mark T
    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.
  20. Mark T
    Is that the same truck, or a different survivor ?
  21. Mark T
    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.
  22. Mark T
    It might be cheaper to smoke pot.
  23. Mark T
    I think the Scania / Mack V8 was more about the mighty E9.
  24. Mark T
    It's an interesting history. I think many guys might be surprised the extent of it.
