    Great movie!!!

    Looking for an original battery box cover for my 79 R model.

    I ordered one and should have it by end of week. I’m glad they’re still available. I’m pretty particular with things and matching gauges is a must. My truck was missing the plastic filler cover over the extra gauge hole so i figured instead of finding one of those I’d put a boost gauge in. Who doesn’t like more gauges anyways right !?

    I think I found a gauge. The gal at the local Mack dealer searched all R model gauge part numbers which began with 7MT and came up with 7MT232 for a 0-50psi manifold pressure gauge. I’m guessing this will be the correct one. I was able to locate a picture of what I think it looks like. I plan to get one on order, dealer quoted $118.

    Thanks for all the comments. I’m excited to have it. Work has been super busy so I haven’t done anything except take it up and down the road a few times. The old cool power sure has a nice whistle to it. All fluids look great but I will probably change everything to start fresh and go from there. Jeremy

    Thought I’d share a couple pics of my R model that was delivered this weekend. I purchased the truck from the wife of the original owner who passed away last year. He had ordered it new in 1979 and was the only one to drive it. The truck has 118k miles and was used to pull a lowboy. It’s completly original except the blue paint which was done at the Mack dealer when truck was new.

    Thanks for the reply. I have been trying to find one for sale, heck been trying to find a pic of what one even looks like.

    Anyone?

    Great to hear. Mice suck but better then needing a new engine.
  10. seyser
    Anyone have any pics of one? Also are they still available through Mack?
  11. seyser
    Was there ever a factory boost gauge offered for the R models that matched the other gauges? Jeremy

    Has the rare oem canopy and light kit. Beautiful machine indeed.

    I always think patina wins over a perfect shiny paint job. I’d leave as is.

    Welcome to the forum. Some nice looking hardware you’ve got there!

    I’m looking to possibly purchase a truck to use on the farm hauling grain. What are your thoughts on a R model with a 168” wheelbase? We mostly haul short distances. I know it won’t ride the best but I’m young and can handle that. How common were short wheelbase trucks? I see some pics of them from time to time, was a short wheelbase mostly used for lowboy trucks or what was the major benefit of being short? Jeremy

    Has anyone ever read this book? I just happen to run across it and might order a copy.
  17. seyser
    I have one on a pallet. I would guess in the 400-500 lb range.

    Also check the pass side frame rail near front tire as the vin will be stamped into the frame and should match door tag. Nice to confirm as cab or door could have been swapped at some point.

    Price updated to $5600. Looks like a solid truck at a fair price.
  20. seyser
    Sounds good. Thank you for the info.

    Is there anyway to tell visually if an injection pump has been adjusted or turned up on one of these engines? Is there a factory seal wire of sorts? Like for instance on the older Cummins 12v there is a tamper proof screw that must be removed which was always a tell tale sign. Anything similar on the old Mack’s?
  22. seyser
    Thank you for the reply. Were/are the tip turbine setups pretty reliable on theses engines?
  23. seyser
    I’m kicking around the idea of purchasing a truck to use on the farm for hauling grain. I have found a late 70’s R model that I may have some interest in. It has the ENDT676 with a TRXL107 and 4.17 gears. How would this do for a farm truck? What kind of mph could I expect with this setup? The engine is the tip turbine with side mounted intercooler and is painted red in color. Was that an original engine color used in late 70’s? Would this be considered a 285 hp engine? I read some places calling it the 300 maxidyne or was that in later years. Thanks, Jeremy

    So I gather they ride better then camelback but not as heavy duty?
  25. seyser
    I didn’t take the pics, I know not much to see. I’m told it’s Mack suspension and it’s not camelback or air ride so I’m thinking taperleaf. Was this a common used suspension? What’s your opinion good or bad? I’ve never heard much about them.
