  1. I'm very fortunate to finally have a DM. It was the very first Mack model I ever drove, and I've always liked them. This one is a very solid truck under all the bent parts , LOL It was used as a site truck and never got much attention. Its a 1989 DM 690 , T2070 trans with 300 maxidyne engine. I really like it !!!! I have a question though. Everything I've read says a Mack air shift trans will have an air filter. I can't seem to find one. Do they all have one ? Or have I not looked far enough yet ? Any info would be appreciated . Thanks

  2. He won't be 4 for another month or so, but he loves to help me when I'm working on stuff. He doesn't like to wear the dark helmet, so when I need to weld something, he gets to be a handful because he wants to be there with me but I can't have him watching...until now. Bought a pair of the soft goggles that come with a #5 lense for oxy/acetylene cutting & welding. Bought the #10 lense to put in them...so now he's got his own welding goggles. Wife's dog will tear up anything she can reach if she's left alone...ESPECIALLY if there's a storm, guns going off, or fireworks. Those plastic kennels? Destroys them and escapes. Those collapseable wire ones, same story. Wife bought a damn cage...1/2" square tube & 3/8" round tube...double sliding latch...HEAVY DUTY. It holds her, but she spills the water and chews the bowl. Yes....stainless steel bowl has teeth marks. Anyway, bent a couple 3/8" steel rods & welded them into circles...one the bowl slips through, the other slightly smaller the bowl sets inside. Used 1/2" square tube to make a base, then added 4 uprights at the mid points to hold the 2 rings...top (larger) ring about an inch above the lower (smaller) ring. Base bolts to the floor of the cage with some J-hooks. Bowl is protected by the large ring, but it doesn't interfere with the dog's ability to drink. My boy was on my lap with his hand on the electrode as we were welding it all together. Need to find some kid-sized welding gloves...and his face could probably use a little more protection. If I do my job as a dad correctly, he'll be the only person in his kindergarten class that can weld, back a trailer, and back a hay wagon. Now that he can reach the pedals on his little tractor, we'll build a trailer for him to pull. Probably have a wagon by next summer with a hitch welded onto the handle so he can pull it around, too. Anyway, that's the goal I've set...got a year (or 2 if we hold him back...he's really small for his age)...I think it's doable.

  3. The story is there's Turkish construction company which built alot in Moscow during 90's and 2000's including a borough of skyscrappers which was named Moscow City. They brang a fleet of Mack trucks from Turkey and used them for moving machinery and transporting concrete (those were mixers). All the trucks were painted yellow or amber and were either DM686 and DM690. I don't know the exact number of the Macks but to my understanding it was 30 or so trucks. You could see them driving in Moscow in 90's which was no doubt uncommon and impressive sight. Years flew and closer to 2010-2012 the trucks dissapeared. The last time I saw one was in 2010. Once I even googled the company address and called the office. The guy redirected me to their transport department and the manager told me they had one or two Macks parked in a yard. Promised to call me back when they would figure to sell them off but it never happened. I was not really eager to purchase a DM and was partly happy having an excuse to not gab one more boat anchor to add to my fleet of projects. A few years passed by and a week back a friend texted me with photos of yellow DM and a phone number. I immediatelly got excited by the look of the rig and also by the van body installed on it. If I bring the truck back to life it could be used as a camper and if not (as long as it wouldn't) I could use it as a storage. So I made a call and the guy explained the company cleaned the yard indeed and they were going to set the price. A few days later he called me back and declared the cost. It sounded higher than would be reasonable for a non-running truck nobody needs for job but my argumentation was declined by "sells for that or... scrap?" Actually it was nearly 1.5 times of the scrap cost so I figured it was just money and not really big money. And I had a spot in my property... I could make free selling my GAZ-66 truck which didn't run for the last 15 years and was parked because of its military van body I used as a storage. So the puzzle achieved shape. You know when you assemble a puzzle you want a nice picture. I wasn't the exception. Further story was realitively fast. To my pleasure the truck was parked locally. Just 40 or so km from my place. Absolutely surprizingly! I didn't need to drive 1 or 2 thousand km to get it home! The issue was the van body heigth so I had to look for a wrecker not a low boy. Turned out the qutes were very reasonable and I got the Mack parked near my place in a few days. We had to remove the prop shaft to prevent the tranny from spinning. IDK how it was critical for towing just 40km/25 miles with 60km/h top speed so figured I wouldn't experiment. Bad thing the wrecker couldn't get into my gates with the DM hooked so I had to park the latter in the street. The most right way was seemed to fire the engine up, reinstall the prop shaft and drive it in. I connected two fresh batteries, checked fuel in the tank, hand primed and made a few attempts to crank. Having no luck I took a can with diesel and primed by electric pump. After a minute or so of cranking I heard sparks and in 30 seconds it fired up. Fun strated after I tried to accelerate by the pump lever and having no reaction I tried to shut it off. No reaction!!! Honestly I was prepaired for such the scenario. Grabbed a piece of plywoood and closed the intake pipe. Turned out a couple of small air lines were found dissconnected and the engine continued to spin sucking air through them. Ok, we removed the supply hose from the can and after about a minute of consuming the content of injection pump it rest in peace. Further investigation showed the rack stuck due to 2 stuck plungers. That's a Bosch pump and it didn't have a side cover to get to the plunger tappets. So turned out as a not really simple story but that's another story I'm currently in.

  4. Been a while since my last visit but got something to tell. I have been looking for inline pumps for my E9's for years. Found a few, missed out on a few more. But today I got the Holy Grail of Mack Inline pumps. A new never on an engine PES8P Bosch E9-500 pump from Italy. A Smoking Deal to boot! Actually it is for a Renault 500AE Magnum which is the Mack E9's Europe name when Renault ran the company. Renault was responsible for putting the E9 in French military tanks and transporters rated between 750-900hp. This is probably one of the last new never on an engine pumps in existence. Just had to share something seldom seen or known to still be available. Wild goose chases do turn out well some times, didn't what to tell and junks myself before it was in my greasy hands. By the way there are rebuilt Bosch PE8P 13mm inline pumps available from the same place just not face mounted but a mounting place could be fabricated without to much trouble for Big Horse Power. Got a real nice BW S400 Turbo and new military nozzles to go with it too. How does a conservative 800hp sound?

  7. I don't have much this week, because I'm in sunny Florida. I have some pictures on my camera, but I haven't seen any big trucks. I did see this on the window of a car in a parking lot at an undisclosed location. Probably been pulled over a time or two I'd guess. here is a girl in a car, from the interweb. Here's a girl out of a car, from the interweb. Here's a girl on a car, from the interweb. I did go to Hooter's in Florida. The big fish sammich was delicious!

  10. the only way to get over this is to A: ban all news media for 6 months. without news media to stoke the flames of fear, the fire will go out. B: fire every single politician and start over from scratch with term limits, and no chance for pork. by replacing every single career politician with citizens with no hope of becoming the people they replaced, just maybe we can get our once great country back.

  11. I found a NEW inline E9 pump and the topic strayed to Hot Dogging Macks and such. So this topic is about getting the most out of what you got, not just keeping the old dog barely alive. To start I Love BIG Power, it comes at a price but with these Old Macks is so EZ to Have. Not for everyday working truck modifications but for hobby trucks and occasional outings to take the old mechanical dog on a "Run". This topic will not be for all but will be useful information all the same. I finally got some space and time to pull out the Tank Quad Turbo set-up that I got some time ago. In preparation for this I was looking for inline E9 injector pumps. To start the NEW E9 Pump was damaged in shipment. Fed-Ex Said that claim was to be files by the shipper. Pump came from Italy so not hoping for a lot. It has to go to the pump shop for repairs so.... Lets get it Turned-up. Thinking 20% on fuel and 20% on the governor. This will be a Hot road engine maybe going in a MH Ultraliner that is out beside the shop, only has 118,000 original Km on the ticker. Along with that I got a pump or two that I got over the years to put on the calibration machine just to see where things are at. (2) 12mm, 13mm & 14mm shown. Power start with the pump and you got to know where things are at to begin with. Now the Tank Engine set-up. Mocking this up today on more than likely the engine that will be rebuilt to handle the power output that this set-up will deliver with a 14mm pump and a little "Secret" stuff. No shifting required with this set-up, as manual trans do not shift well over 2500RPM's. Trans is the bullet proof cable shifted, no electronics, Allison HT750CR Automatic. There were only a very few E9's with Automatics orders only by the US Military and I believe they were HT740 Allison's. Lets talk, Hot Rod Stuff, From the other post 300bar injector pop-off is higher than Mack spec but it works better for fuel atomization it is 50bar higher than Mack spec. About every 25bar the engine timing needs advances 1 degree, 2 degrees for 50bar.

  12. I'm still looking for big trucks, but I haven't seen any anywhere. But here's something completely different, all from the interweb. A girl in a plane! A girl in a train- A girl in a boat- And the usual "girl in a car".

  16. My experience on the Ford truck forums is they either get the answer, fix the issue and never come back to say thank you, or get an answer they do not want to hear and go ask other places until they hear the answer thay want to hear.

  19. Picked up the cab today and made it back home without damage or dropping it on the highway, again. That was a huge relief and yes, I drove like an old lady. The work finishes off the cab and really makes it look great. Took some pictures with and without the seats. I just wanted to see how they looked with the headliner in place. Such a huge difference from when I dragged it home all those years ago. It truly looks brand new!!

  21. Most times bead lines, embossments, dimples are placed to strengthen a panel to add rigidity. A supplemental benefit is to dampen the harmonics, as previously stated. Floor panels are another good example of this process. The panel can be much thinner, i.e lighter, but have the same strength of a much thicker and heavier panel.

  22. Howdy folks, I had my eye on this mack that had been sitting alongside the road in Great Falls, Montana for a couple years and one time passing through it ended up having a for sale sign on it. Got in touch with the Gentleman and after two years of working out timing, I was able to bring it "home" in July of 19. Unfortunately, due to my military service my home tends to move often on me, so I've had to leave it in North Dakota until I can work out details back to "home home" in PA. After some research I had found out that I had a B613T, which came with the ENDT, and the gentleman had informed me that the engine had undergone a fresh rebuild when the current set of tires were put on it back in the 80's. By the time the tires had been run out, other trucks had been better suited to the construction work and the truck was retired from service. I have not heard it myself as it needs a radiator put back on, but sometime around 2017 the truck was started and ran, after freeing some sticky plungers in the pump. Fast forward to March of this year, another B model pops up on craigslist and it looked too good to pass up. I had been looking for a tandem, but another single axle that had some winches and setup as a tow truck... why not? I don't know many details about this truck, but discovered it is another 613 model, but no longer has the turbo engine in it, but the more common thermodyne. I'm not sure what happened to cause the engine swap, I can only venture that maybe they got tired of having head gasket trouble with an earlier version of the engine and swapped it out? Regardless, it "seems" to only have 14k on the Odo, but regardless if that's true mileage or not, the cab doors close as soft as a feather, and the seats as well as the headliner are all pretty well intact. This truck had sat for awhile, and I had the unfortunate displeasure of discovering that it had the PSM rotary pump instead of the inline pump. After scrounging high and low to find a replacement for the worn out pump, I now have my eyes set on getting the injectors taken care of. Being 7000 miles from the truck right now, and the fact that it hasn't even left the gentleman's place to sit on my friend's ranch, that's made that last task a little daunting. I'm hoping that after I get back from my deployment, I can get the transportation taken care of and get the injectors in good shape so I can fly out, put it together and hopefully hear it come back to life. I will be reaching out for multiple reasons I'm sure in the future as I tackle these two trucks, and I'm looking forward to getting them back on the road and enjoying them. Thanks in advance for all the support! Brandon 1961 B613T-4742 1959 B613T-2839

  27. Found the problem. After exhausting everything I could think of I finally broke down and pulled the pan. The pick-up was broke off the oil pump. Looking at the broken opening to the pump and lining it up with the dip stick I can see that the oi level was about half way up the opening so when i started the engine, the pump could get some oil but as soon as it pumped that oil upstairs the level would drop to the point that the pump starved and the pressure would drop off. The pick-up must have broke off when the truck was rolled and the oil level was higher when i initially started it up so it didn't starve.
