  1. I have a 2003 ch , started to replace a front windshield but the rubber window channel is different than my last mack. The older ones have a strip you remove then push the window out. The 03 has no strip and a wider channel. So whats the trick to remove the window ? Once i do get it out do you need to use a cord or wire to re-install ?
  2. My 460-P has zero power below 1450. The power is between 1600-1850. I have had 3or4 different programs fed to the computer and still has no low end torque It is a logging truck and starting out on even a medium grade is a bitch. I have tried to twist arms at the local Mack dealer but when they attemt to get a new file for the computer the factory just says no "live with it". The computer geeks at the factory don't live in the real world.
  3. Will increaseing the pop off pressure of the injectors incease the power output ? I'm working with a 2003 460-P etech e-7.
  4. Ok out there i know someone has the answer to this question. Can a local Mack dealer program my truck ecu V-Mac III. I'm not wanting the original Mack program i'm looking to increase low end fuel supply. I have discused this with a couple of mechanics who say Mack factory is the only ecu program supplier Because of air pollution b.s. it seems they control all computer imput.
  5. CAN A LOCAL MACK DEALERSHIP PRORAM THE ECU OR DOES THE FACTORY SETTINGS HAVE TO BE APPROVED AND PROGRAMED VIA THE FACTORY? wHEN MY 2003 WAS NEW WE RESET A FEW THINGS ,BUT I WASNT THERE WHEN THE CHANGES WERE MADE. I WOULD LIKE TO HAVE THE LOW END TORQUE CURVE MODIFIED SO THE POWER COMES IN AT A LOWER RPM.
  6. There is no smoke under acceleration and very little when shifting up. I had the rack run about six months ago which made ie run a little smoother . Mack in Seattle has a very good computer tech maybe ill see if he can do anything with it. I'm not getting any blink codes or malfuction lights
  7. I have kept the truck serviced and maintained beyond what is even called for. If you were at 1200 on the flats a pushed it to the floor you would very.very slowly gain rpm. Once it hits 1550 or so it get a real surge of power and pulls extremely well.
  8. The truck has 3:91 gears and 11;24.5 tires. My last truck was very simialr to this one except a manual pump 400 It is kept serviced and runs great from about 1500 up. It just doesn't seem to get the fuel at low rpm. Iv'e read some posts in a few other forums and it seem to be a common problem with the computer motors.
  9. Well i'm sure this has been asked many times but here goes. 2003 ch 613 e-7 460p . This is a logging truck but it has never seen the woods. I run from log yard to log yard delivering loads that don't make minimum quality grades. So i ran into a off road job to make a few extra bucks and found out that the truck has will not pull even a slight hill if you stop a try to restart which happens alot because the loge are scattered along the road and the loader folows behind you to pickup the logs and load the truck. No matter how much throttle you give it it just wants to stall out. The loader has to give it a push until RPM builds and the boost comes up. Anything below 1450rpm it is worthless. Is there a ecu program change that my local dealer can put in or is this the same old b.s. from the factory worrying about a little smoke or whatever. This has got to be changed the truck is no good with the current set up.
  10. I have mack 44,000 rearends, i had a problem with the vents plugging on both rearends and then losing the pinion seal so i put a set of stemco esp vents on about 3 months ago. I thought i would inspect them and removed both vents. They both had alot of air pressure release when removed. Is anyone familar with the esp style vents? is the pressure build up normal ? seems like it will cause a wheel or input/output seal to fail.
  11. Thanks for all the good info,it helps a lot to have all of the input when it comes to figuring this stuff out.The engine has been very good other than some computer grounding problems when i first bought it. I gross out at 88,000 and average 7.1 to 7.3 mpg so that makes the stop at the fuel pump a little easier to take.
  12. Well looks like my engine exhaust temp problem 1150 + was the thermo coupler in the exhaust pipe. I was able to put it in a hard pull several times and the highest temp it reached was about 925 degrees. With al the new parts turbo,charge air cooler etc it pulls much stronger than before so i have at least improved it's performance.
  13. The saga continues, replaced the thermo coupler on the exhaust pipe today. Tried to get it heated up but running around without a load just doesn't let it pull hard enough to develope much heat. Tuesday will be the test.
  14. 33 lbs is the max the the computer will allow,i blocked the waste gate acuator off and ran it up a hill it hit about 33 or so and then cut the power way back.The electronic malfunction light came on and an over-boost code blinked out. Don't you just love computers.Now if they could just tell why the high exhaust temp is happening they might do some good.
  15. Hello guys, well no work today so jumped in my pickup buzzed into Mack and picked up a thermo coupler for the turbo.After some talk with the mechanics we have agreed that the boost is correct at around 30-31 lbs. We also discussed the possability of an electronics glitch but i'm not getting any malfunction light and we have scanned the system with there laptop and found nothing.Before all of this started the exhaust temp would rarely get to 900 degrees. Water temp is still 180-190, The bearing in the turbo was letting the impeller drag in the housing so we replaced the turbo still high exhaust temp so we checked the charge air cooler it was cracked down the hot side so that was replaced, still high exhaust temp air and fuel filters changed, still 1150 degrees and climbing. That is now where i'm at so now i will replace the thermo coupler. If that fails we are going to hook up Macks lap top and see what temps it will read compared to what the gauges say.
