      What cha' Cookin' ?

      By other dog · Posted

      Me and Mike Jackson took a couple of long loads from Hirschfield Steel in Lynchburg down to Hirschfield Steel in San Angelo, Texas one time. After we got unloaded we went to a motel because we were going to load a load there the next day going to West Virginia. We went down to the lounge to have beer and it seemed like everybody in there was walking around drinking beer out of a punch bowl. I thought "man, I like beer, but these people must REALLY like beer", those were some serious beer drinkers at that place.

      B Model Door Latch needed

      By Max And Chloe Hilliard · Posted

      Taking a look at the crossover to IH trucks, the pictures shown will not fit. The IH models have a push button handle and the Mack has a swing handle. The latches, although look similar, are different. They might fit an R Model Mack, but not a B Model. So….I am still in the market to buy latches for my B Model.

      B Model Door Latch needed

      By Max And Chloe Hilliard · Posted

      Thanks for the potential solution to my issue. Luckily, we have Southland International here and George has a vast array of antique Internationals. I will be heading there tomorrow with this new information. As for Watts, I gave them the description and the serial number of my truck and was told they didn’t have any. I did not have those part numbers. If the International Dealer isn’t able to help, I will reach out to Watts again.    Thanks for all the great information!! This is my 61 Mack

      Mack E6 4v HP??

      By Vladislav · Posted

      By very simple reason my "bet" the engine is E6-350 Econodyne. I have one in a 1988 R-model with similar injection pump. The "bet" is due to the 9-speed transmission used. Mine has the same. You don't need 9 speeds behind a Maxidine since its torque curve works well with just 5 speeds. I have another R-model also 1988 made which has T2070 7-speed transmission. Its ratios are similar to T2050 5-speed but have two "low holes". There's a similary rated T2060 6-speed and T2080 8-speed. All trio has first 5 gears spread much wider than "multispeeds" T2090, T2100, T2110, T2130 and T2118. Wider gear steps are aimed to serve with Maxidyne low torque curve engines. Ok, that my other R-model has its engine stamped as EM6-300L. Almost as Keith described regarding his DM.  It's a bit easier to identify R or DM since E6-350 would be R/DM688 model and EM6-300 would be R/DM-690. That's what I have on the door tags. RW's are all 613 or 713 with Mack engines so no clue up.

      - I double sticked and old Mack to feed a stone crusher in 12 and 14 hour shifts six days a week all summer to pay for my chemistry degree.
      - Because I wanted to sleep for 1 min and 26 seconds each trip out of the quarry at the crusher's vibratory dump box at the top the quarry during those 12 hour shifts, I bulled the old MACK up long 20 degree and sometimes steeper grades.
      - THAT meant that I split each gear 1, 2, 3 after coming out of boggy low.
      - All I did was rev to the right engine note, reach my left arm down through the steering wheel to hold the curve I was on or hold the truck's path steady; slip out of 1st, throw the 2nd stick high into low and slip into 2nd gear... rev to the right engine pitch, slip to high.
      - Then when it was time, reach through the wheel again, slip high to low and 2nd to 3rd {if I correctly remember 60 years ago}.
      - The Igneous rocks were too heavy and the grade too steep for me to ever get into 3rd high.
      - The crusher team were the mechanics for everything and had replaced the old Mack's tranny gears because they had been ground too much. - - They later told me they didn't believe me when I told them I slipped all my shifts because the gears showed no wear.
      - Except for start and stop; Not once did I use the clutch because that made my leg ache too much after an hour or so.
      - I slipped all my standard 4 speed shift vehicles all my life...just to be with the music of the engine and car or truck.

      - I hardly ever change disc pads or brake shoes because I always slipped my gears downshifting...
      _ I learned that because the synchro rings got shot on my 1968 Volvo 122S 2-Door 4-Speed with an electric overdrive because I stupidly speed shifted and ruined them. https://bringatrailer.com/listing/1968-volvo-122s-17/
      - [Note: That Volvo's original owner was a Canadian Submarine Captain who rallied it and that is why it had Volvo's unique electric overdrive.]
       
      - {I clear coated over the bone white with Cadillac Firemist Green and painted the grills Black because they were dented...gosh it was stunning.}
