    Mack DM Shutting off (fuel problem)?

    Believe it or not I stayed late shortly after this post and traced the fuel line. No issues there. I then removed the tube in the tank which draws fuel and inspected it. I found a piece of plastic wrap stuck inside the tube. Like a part of the clear window in a paycheck envelope or wrapper from a pack of cigarettes (couple of these guys smoke). Put back together. Ran fine since. What are the odds lol

    Mack DM stalling (fuel problem?)

    Thats the first thing we will try Monday. Thanks.
  3. I have a 1995 mack DM. It is an oil and gas service rig. The mack motor runs the service unit body also. Recently, I sent the mack to a local mack garage bc it had a loss of power and was stalling. They told me it was the charge air cooler and fixed the air compressor unload valves. This did not solve the issue and they had it over a week. The truck starts and runs. It idles fine, does not have a miss, and the service unit seemed fine also. We drive it down the road and it acts like its out of fuel and stalls. It takes several cranks to get it back started also. As time progresses it is getting worse and worse. I had the crew do the normal (changed fuel filters, air filter, check battery cables, checked fuel tank cap, pick up tube in tank, ect). We need this rig to run bc unlike a normal semi, my 3 guys who work on the rig daily go with out a check when its broke. It is an econodyn. Fuel linkages are manual and does not appear to have a computer on the frame. Please help as we are not sending it back to mack unless it is absolutely necessary. Thanks all!

  5. Hello I have a 1995 Mack DM truck. Our service unit for servicing oil and gas wells is mounted to this truck. It went into a local Mack garage recently for loss of power and a stalling problem. They changed the charge air cooler and rebuilt the air compressor. This did not solve our problem. The truck seems to run ok servicing the wells (the rig runs off the mack motor) but the more we try to drive it the more the problem happens and gets worse. The truck used to stall once or twice going down the road, now it stalls 10-15 times within a mile. We have made sure the tank is full of fuel, the fuel filters are all changed, checked the air filter, (the normal checks). This truck has mechanical fuel linkage and the injection pump looks pretty new from just looking at it. I have read on this site other times about the pick up tube having a pin hole or a leaf being in the fuel tank obstructing the tube at times but I am pretty sure that is not it. The fuel cap spring also moves and is clean. I am looking for any suggestions as I have a crew of three guys that rely on this Mack to run for them. If the truck does not run then no one works and does not get a check. Not to mention we are up to our eye balls with work thankfully, now if I could just get the truck to run. Please help if you can! I am not a professional by any means but I try my best. Thanks All!

    Cv713 steering

    I have an 07' Mack and 2- 05's. What seems loose to you? (Play in the wheel, is the truck wondering?), I also have a couple 1980 macks and 2- 1998 Rd 688s macks. I can tell you depending on what your used to they all steer a little different (easier to turn the wheel on some trucks then others). In fact, one 1998 steers really easy, the other is a bit stiff to turn but still turns good. Just curious on what exactly concerns you bc I've done a bunch of steering work on all these macks.
  7. Hello all --UPDATE: had my mechanic tank the tires off today. We found a brake drum balancing weight stuck inside the aluminum wheel that the Weld did not hold the weight to the drum. A few local shops said they haven't seen this very frequently at all if any? Problem solved! Thanks for all your help. Seeing your posts helped me to dig deeper!
  8. I agree with TJC, I have two 1998 Mack Rd 688s and have fought problems like what your describing in the past. It's most likely a torque arm or dog bone as my mechanic calls them. I have found over the years only changing one at a time ends up causing me hardship down the road bc the other will need changed. When one wears out I change the other also to ensure the rears are not moving any direction they shouldnt. I'd stick with the torque are deal. If a mechance says there fine then you have a spring issue with pads or trunnion bushings ect. Keep in mind if the torque arm had movement previous this could cause other things to work also. Good luck
  9. UPDATE: After a some what heated arguement at the local rearend Shop this morning I am more and more determined the tire man who changed the tires before the truck went on the road left something in the simulator or something is broken behind the dust cover of the housing. The local rear end Shop refused to take the tires off to check and said the entire rearend is completely blown even though I took them a sample of the gear Oil. They told me the sample doesn't help or mean anything. They told me I should buy the rear suspension. Cut off from the guys buddy and scrap the whole rearend. What a valuable lesson I learned today. Thanks all!
  10. Called both local shops, they both confirm that the entire rear is blown, and they both claim they are booked up for 2-3 weeks now. Guess I am in the wrong business. . . I must say I am a bit spectacle with there responses.
  11. The truck has aluminum wheels inside and out and have been checked so not that Transmission is used, but has 90 day warranty. This issue started to occur a few days after we drove the truck a bunch. Mack and a drive shaft Shop remade brand new drive shaft and new u joints and straps also I did hear about the auto diff lock peanuts and there is a section at the top of this rearend with its own Oil plug or so it appears. What would I do there? The truck was just working in a really muddy area where this would of been used a ton? Any suggestions? Is that a part we can change on our own without pulling the pig?
  12. Hello all, I have a 1983 Mack superliner with factory Neway air ride suspension. Ithe is a single Frame and I believe it has 38,000 rears. It does not have a power divider with the switch. I recently put a t2180 transmission is this truck and just got it back on the road and now I am hearing a sound from the front rear. It sounds like a big heavy flat washer dropping from my hand to the ground. It does this sound multiple times in 100 yards. The truck is not skipping a beat and after pulling the side cover off there does not appear to be any teeth missing or damage. Fluid was super clean and no shavings or steel dust at all. All my rearend shops are telling me the rearends blown and they also can't look at it for 7-10 days. That's a lot of revenue to lose with it just sitting. I can also tell you since this noise started a week or so ago, as he ran the truck it has gotten more frequent and louder also. Any help or suggestion would be very helpful! Please let me know.
  13. So, I had my mechanic check the truck out and it's actually the torque Rod arm. One side has no bushing in it at all it sounds like. My mechanic calls them dog bones. I have one ordered. 250 bucks. I will need to do this trunnion soon though! I appreciate the help and glad I found this site. Thanks all!
  14. Thanks, I sure will first thing tomorrow I have not done that
  15. The truck has camel back Mack suspension. 44k rears. I crawled underneath er and inspected the springs and area around the springs. No broken leafs, when I apply the brakes the rear end of the truck shifts slightly and you can just barely tell out the mirror the reagents walked a bit. When you apply the throttle it goes away. The truck still drives down the road straight and narrow
