  1. I assume you're not new to trucks, but just in case you are: PLANT YOUR HEEL! If your heel isn't planted on the floor then it's impossible for YOU to maintain a steady throttle position. But like I said, I assume you're not new to trucks, so I would guess a governor issue as well. Any clue how many miles on the truck? I'm sure someone on here is savvy with the 865 governor and can tell you what's likely going on with your governor. Not sure if there were multiple fuel pump options on that motor, post a picture of your fuel pump just for expediting the solution.
  2. Ouch!! 3100 rpms?? I'd chew a driver out big-time for that one! Not just for potential damage to truck, but also for sending a freight train down a mountain to who knows who at the bottom! You ruin your engine going downhill you're F 'ed, and most likely going to kill yourself and possibly others.
  3. Diesel is about 3.10 up here, driver hourly rates are $20-25 or so I believe. What's important is that you're making money; just be careful on 30/60/90/120 day pay, it's all well and good til the economy tanks and you're left hanging for 3 months worth of unpaid invoices. Sounds like your an effective entrepreneur! Keep it up!
  4. PA triaxle rates are in the $75-$100 per hour range I do believe. I don't know how different operating costs are, but 55 for a triaxle? Not sure how anyone makes money on that.
  5. Check your fuel supply pressure; had my 95 e7-350 make the same sound for a while, only difference was mine did it at the top end, near 1800 rpms. Took 2 sets of fuel filters to get rid of it. First set cleared it up for a few days, second set made it go away for the past year or two. Your supply pump could be shot, not making enough pressure until it gets up a little bit in RPMs.
  6. My '79 Mack endt676 wants to go to 2100, 2300 max for your shifts. The 2400 he referenced is the standard gauge limit in most? Mack trucks. The engines never go to that (hopefully) but it's the peak reading on the gauge.
  7. Don't know where you're located but .y dealer has been fine for Mack hubs in the past. Or you can try a junk yard...
  8. Unless of course they're single axle dumps and the dump bodies have their own subframe that disperses the hoist cylinder point load.
  9. Pennsylvania most of our dump trucks are triaxles rated at 73,280 lbs. Tractor frames also are not typically as deep as traditional dump trucks, so when you raise the dump body the hoist cylinder puts a massive point load on the frame right behind the cab. Watch for frame failures around the back of the cab. You really should be running double frame chassis for dump truck work.
  10. I frequently shift my '95 e7-350 around there too unless I'm climbing and need more, but it doesn't go above 1850-1900.
  11. Governor is probably set at 1850, which is probably about where peak horsepower is. In general an engine will tell you where it wants to run. Sounds like you're driving it about right.

    Sad date

    Haven't heard of this story; link?
  13. Serial number?... Send the VIN to the Mack museum in Macungie and they'll get you all the original build info for the truck; be courteous and give them a donation as donations are how they sustain their operations.
  14. You can buy new Mack upholstery for them, you don't have to invest in a new seat. Mack sells the seat covers. But if you want a new seat, I like the Legacy seat in mine.
  15. Maybe aluminum elephant pad holders too. I have an R model with 'em.
  16. Yes, it's an adapter plate. The plate sits on the floor via the "depressed" corners, which allows the bolt heads space for bolting the seat down. If the seat you buy doesn't match a set of holes just drill new holes in the plate. May have to do some mock up first to make sure the seat fits where you drill it, the R cabs really don't have much room behind the seat for reclining. About every seat I've had in a Mack R or DM rubs the rear glass.
  17. If this isn't a daily driver you might want to stick to a bostrom from a price stand point. Hard to justify a grand for a hobby truck seat. But if you're in it 40 hours a week then I'd say it's worth it. I think you can get just the foam and seat covers from Mack.
  18. This looks like the seat we have, but we paid about 750 for it 5 or 6 years ago. https://www.opentip.com/search.php?cPath=12515&products_id=11210630&gclid=CjwKCAjwtuLrBRAlEiwAPVcZBpoY-RoPJvXB08FhKcEvdaJKaT3edWJ7gKdf1X1Cjdl_5QvB1Z_gGRoCJrYQAvD_BwE
  19. Should be pretty universal, that plate on the floor unbolts and new seat will bolt to it. We put a Legacy? Seat in with armrests. Really nice seat, but the left arm rest interfered with the seat belt so we took that armrest off. Trans in the truck is an 8LL, so I don't need the slot under the right armrest very often. If your transmission pattern uses that gear slot much you'll want to avoid armrests, but if it's an 8LL you just lift the armrest up a few inches, pop it in low to start out and you're good to go.
  20. Looking at that tether, it's gotta be somewhere low along the crank skirt.
  21. Probably just the "puff limiter" got disconnected at some point. The puff limiter uses turbo pressure to control fuel rack travel in order to minimize smoke. It's not uncommon for people to disconnect the puff limiter in order to get the turbo spooled up faster. End result: your truck goes down the road like the RMS Queen Mary.
  22. There's more on there, just need to set the search parameters. Walking beam seems to be common for concrete mixer chassis, I imagine that'd be a stiff ride empty. You could put springs on instead. I drive a 2001 s/a freightliner oil truck in the winter, and I've driven a 2015 KW propane truck. They are nice to drive, the 2015 was a rocket even loaded. Watch out for speeding tickets and aggressive driving, the newer ones keep up with cars on takeoff, which can be dangerous.
  23. http://www.truckpaper.com/ListingsDetail/Detail.aspx?lp=TRK&OHID=27659059 2004 dm688s cab and chassis with a 400hp e7 and an Allison. Indiana.
  24. We are blessed to be the strongest country in the world, and to be honest it has led my generation (I'm 30) to become soft, never having a major war involving our country completely. I.E. Civil War, WWI & II all happened within 40-50 years since the previous war, affecting everyone in the country. It's been about 75+ years since WWII, and while we have had the Korean war, Vietnam War, Cold War, and War on Terror, my generation is the first in a long time to not have a Draft. I am genuinely priveleged and lucky to live in the "now" when we keep an active standing army continuously "training" overseas against live targets as Mack Tech pointed out. I have no doubt that this is a contributing reason we stay a Super Power, and I have no doubt that is intentional. Playing the world's police force also gives us an excuse to have our boys anywhere in the world at a moment's notice, which could be argued as unnecessary if one has "Isolationist" preferences regarding national actions.
