  1. So all Mandrewoid needs to do is turn that screw a turn or two one way or the other to get to 2100 rpm I figure.
  2. 12,000/day x 365 days = 4,380,000 per year.
  3. Can you post a picture of the exhaust side of your engine? I have 2 endt675 motors, one from a U model the other is in an R model. I think the exhaust manifolds are the same, but seeing yours will help me compare to the U model I have.
  4. Sorry to confuse you with yet another turbo model added to the possibilities. Just rechecked, you're running an ENDTB 675 which will be the 237hp variant! Sorry this turbo is for the 283hp variant! I do have a 237 endt-675 sitting outside my garage, I'll see if it has a tag on it tomorrow!
  5. The X in the part number on my turbo just means rebuilt.
  6. FridayParts Turbo S3B085 Turbocharger 631GC5134 174840 199453 Compatible for Mack Truck E6 Replacement https://a.co/d/g7huQZv The things Amazon has for sale never ceases to surprise me.... Not bad at $600...
  7. I put this turbo on my 1979 endt676 about a year ago. Got it through my local Mack dealer, Bergeys. May have been about the last one they had in stock.
  8. Can smarter heads than mine tell if this is the high idle adjustment screw?
  9. Extreme pullers aren't stock by any stretch. Tons of money dumped into special parts. Running a motor like that you get a few hard runs and you destroy things.
  10. Remember this is an old truck. Things are beyond broken in, and fatigue does set in with use. Our 1979 has a weak valve spring that kept letting a spacer disk for the Jake brake that rests on the valve stem pop out. Only way that can happen is through valve float. If the springs aren't stiff enough anymore then they won't keep tension on the rockers and pushrods. Mack engineered these engines for maximum performance and longevity. These engines typically don't hold up to being pushed passed where Mack set them to. I wouldn't take the chance on putting anything in there that could let it go passed 2100.
  11. Maybe; the spokes have the holes for them though.
  12. That truck is done up nice! Interesting they've ditched the steer axle brakes!
  13. I'd buy a superliner with an E9-500. But somehow I don't think that's the right answer! Not sure what weights you're hauling but unless you're running an E9 then Mack has you limited to 12 liters until you go newer than 2007, and after 2007 you're into all sorts of wonderful Volvo gadgetry. I'd probably snoop around for a Pete or Kenworth with a Cummins.
  14. Have you tried backing off the high idle screw? That's how we upped one of our endt676 motors from about 1800 to 2100...
  15. I'm sure she appreciates the effort! We get pizza a lot, and it's gone up probably 30% the past year. Let's go Brandon!
  16. Thanks, hoping we don't set something on fire trying to get it to start lol! It has a switch in the cab to shut power off, red wires labelled RD-A(B through G)-19.0. I'm guessing they're general component power for the power distribution. Wires A and AB are down by the starter going to a Klixon circuit breaker that looks sketchy.
  17. My dad bought a giant 3 binder set in the mid 80's when he bought our first Mack, the 1979 he's still driving.
  18. Pull out any 92/93 book and look up inter-wheel in the table of contents. Its there. I believe mines dated 1986.
  19. Checked the oil pan for water today, had a little bit of accumulated condensation from sitting for nearly 10 years. Drained that out. Oil level is maybe a gallon high, might drain a bit out. Coolant reservoir is good. Untangled some of the rats nest of harnesses, air lines, fuel lines etc that were coiled on top of the transmission. Dragged the battery cables out. Before I gut this cab to make way for all the wiring etc from our 2003, we're gonna dip the fuel lines into a bucket of fuel, toss a couple batteries in and see if we can get this motor to fire up! Just want to know it's a runner before we pull anything apart. We did bar the engine over a couple turns and it was tight. Good compression, barely broken in.
  20. I would not put a 2800rpm give spring anywhere near this motor, all it takes is one screw up and you're floating valves and smashing them against pistons and now you're into needing that spare motor.
  21. Are you sure you can't back off a travel stopper bolt? Much like the idle adjustment screw.
  22. 2100 is your maximum governor target. The precursor endt676 motor which is pretty much an E6 with a 2 valve/cylinder head, allowed 2300 when shifting, but was governed around 2100.
  23. I think the frame side of the trans mount is the same, but the trans bell housing side is different. Uses the same rubber donut isolators I believe. I'll still hold that a donor parts engine/trans combo is a good idea. Even if you don't need the spare parts engine, it'll have the flywheel and housing to match the transmission.
