  1. I want to replace the tab terminal in an Ambac pump for the Dynatard. One bolt I’m told is different, some type of torx? Does anyone know what I need to remove it?
  2. I have the same story as you, mine is an 86 with the same trans
  3. My Dynatard works great at lower rpms but no so great at higher rpms. I’ve replaced the terminal that threads into the injector pump that the wire attaches to, no improvement. I’ve heard that there is a terminal inside the Ambac pumps that goes bad. Anyone come across this issue? If so, is it hard to replace?
  4. Transmission was out of the truck and got a new 4/5th sliding clutch and a new fork. Truck was coming out of 4th gear when you let off accelerator. We adjusted everything the way the book said and trans doesn’t come out of 4th anymore. 4th and 5th shift real tight now, could the eccentric pin need further adjustment? And if so, any advice? Thanks

  6. I found a check valve on line rated for fuel and I adapted it to work with my fuel line, it was about 50 bucks and I haven’t had any issues. The dealer wanted a couple of hundred bucks, crazy
  7. This is a hobby truck, just wanted to do everything possible to smooth it out, cause you know we have the best roads here in Jersey
  8. Can I run lower pressures in my 11x24’s to try and smooth the ride out in my DM800 tractor ?
  9. Take a hose and make a line into a jug of fuel, after priming if it runs, it’s a bad supply line from the tank possibly. Loosing its prime, look into replacing the check valve on the return line at the pump. Mine is external on the pump and I was able to buy a new check valve on line and replace it for like 50 bucks
  10. The new washer nozzles are plastic, maybe find used ones if you want to stay original.
  11. I have sandblasted my fuel tanks and now there are several spots that have appeared that look damp. The tank did not leak and these damp spots are located where weld are. Anyone coat the inside of their tanks with a sealer?
  12. What’s involved in replacing the whole vent window assembly? Does the frame and glass get installed as one unit or does the frame go in and then the glass? I see Mack sells them as a complete unit.
  13. My dimmer was a plug, but my headlights were individual wires, could be my headlight switch wires
  14. Restoring a 86 DM 800, installed the cab after paint and now have issues with lights. All the lights and blinker switch are new.Blinkers work until I turn the ignition on, roof lights are dim.I think it’s a ground issue. I have a good ground to the terminal strips on the firewall but I’m thinking because everything was disassembled for paint, I don’t have a good ground to the dash? Should I run another ground to the dash? Where should it go?
  15. Can someone tell me how all the lines for the puff valve are suppose to run on my 86 DM800? I have a 7 speed trans that has an line coming off it, does that go directly to the puff valve or to a tee mounted on the firewall that gets supplied by the parking brake valve? Any help would be appreciated
  16. My 86 DM800 has an air valve mounted in the top of the dashboard. Whoever installed this on/off valve, supplied it with air they took off the power divider switch air supply. This valve that they installed in the top of the dash next to the power divider valve has an airline that runs to a tee that is in the top of the trans just behind a breather, a blue line comes out of the tee and runs up to the top of the shifter. What does this valve do? I'm installing a new dash, and want it installed with the right valves switches etc...
  17. Where does the AC low pressure switch on a 2006 Granite get 12 volt power from
  18. i had an air leaking from a valve that threads into the top of the transmission right behind the shifter. It has an air line that appears to come from a regulator and a 1/4 steel tubing line that runs from the trans to the area of the injector pump where it is capped. What is this valve for?
  19. On my 86 DM, if I push the clutch all the way in, it pulsates. The truck goes into gear fine. What could be causing this?
  20. Shift knob, have you ever rebuilt one?. I would think o rings would do the trick, but I don't want to start exploring until I hear from someone who's been in one.
  21. My shifter is leaking air, can they be rebuilt? Mack told me they do not have a rebuild kit
