  1. I'll try to take a couple in the morning before it goes out for the day.
  2. "TOP DOG" the millionth mack has a 300hp e-6 with a 5 spd trans and 3.65 rears on camelback. We did have to put a mack reman motor in it in 1998 because a wrist pin pulled out of a piston, it was 50K miles from a million miles on it.
  3. We use the millionth mack 5 days a week. I'll try to post pics later today
  4. I just replaced the printed circuit board on the back of the dash cluster for the same reason because of a bad diode for the low air buzzer.
  5. The book I have shows REV. LL 13.85 REV. L 9.28 REV. H 2.86 LL. 13.28, L. 8.87, 1ST 5.92, 2ND 4.34, 3RD 3.24, 4TH 2.40, 5TH 1.83, 6TH 1.34, 7TH 1.00, 8TH .074
  6. the ground for the VGT control valve. I found out today the dealer also threw a turbo at it also (which bolts backed off and blew the gasket out)
  7. After 3 trips to the local dealer, 1 VGT valve, 2 mass flow tubes, reflash of ecm, replacement of pins on ecm, 1 egr valve, multipule calls to mack help line, and 1200 miles roadtesting and trials the problem has been found. About 10" up the harness from the ground stud on left side of engine block was a break in the wire that would make contact then not. Now ready for the mastercard commercial on what this will cost and money lost in loads lost.
  8. Do you need the sleeper or just the 2 support rails under the cab and sleeper? I have 4 1993 to 1997 CH613 sitting out back that we use for parts and they all have 42" sleepers.
  9. I have a 2007 vision ac 427 501000 miles driver was pulling a load down the highway calls with complaint of no power, cant hear the turbo, and the exhaust temp goes to 1250 deg. He goes to a mack dealer pull code 5-9 failure 5, they replace mass flow tube, road test says its ok. The driver starts heading home 5 miles up road same thing, dealer is now closed for the night, driver drops his trailer and bobtails home 150 miles. I plug into it pull codes 4-5 failure 7, 5-9 failure 9, 5-8 failure 9. Did a recal of the VGT ok, road test with air pressure gauge "t"ed into VGT air line, has 90+ psi till it gets about 175 deg then goes to 0 psi and kicks all 3 codes, I replaced the VGT contol valve and the air filter to it road test no different, I have gone through the troubleshooting book for each code everything checks out I even tried a ecm off another truck to try still same result. I getting frustated so any ideas would be great Thanks
