      300+ rebuild

      By Freightrain · Posted

      Won't reach far enough. Once I get the template and holes drilled it won't be such an ordeal just shoving it in the hole.  If I had to hold it for a long time I would be in trouble.   A bit of progress tonight after dinner with Karen.  I got ambitious to see if I could get the input out of the transmission. Yup. Thanks all for the push to just try and knock it apart without any fancy tools.  I watched a YouTube video of a guy doing it like mentioned.  Few smacks with a hammer and it all popped apart.  Worse part was getting snap ring off the front.  Had to mangle it but a new one comes in the kit. Googled kits and found local Pete dealer has Eaton kit for $260.  I will be getting that tomorrow after work.   Pt 2468 has everything and more then I need. https://ohiopeterbilt.com/products/fuller-kit-clutch-install Question for the masses: The plastic 3/16" fuel return line.  Mack part only?  It is reinforced plastic but only slips on fittings, no ferrel or clamps.  Mine is pretty rough and needs replaced.   I did get the crank hub installed the other night and balancer is on.  Just need bigger torque wrench to get to 300ft/lb.  Buddies only goes 250#.

      Single stick, i wish it was a twin stick.  Multi speed reverse is great for our application.  This mixer gets a 2 section hydraulic pump running off a pto on the rear of one of the countershafts.  Its tucked in real neatly between the driveshaft and the left frame rail's lower flange.  Hydraulic tank goes on the left side of the mixer, and 2 suction lines will loop around over top of the left frame rail into the top of the pump, while the two pressure lines will come out the bottom of the pump and come under the frame rails and back up to run along the left side of the mixer to the control valves at the back.

      This is the current condition of my 47 EE project. The rebuilt EN271 is out and we are in the process of checking the fit of a big block Ford. It is the same truck that’s in my thumbnail photo taken a few years ago. I have managed to acquire all the new rubber cab seals and many are installed. I have a painless harness as well. 

      That engine and trans are on a pallet and probably weigh around 900. I believe the clutch is new and the trans was gone through. 
      Louisiana is a fair distance from the middle of Washington!
      That said, all the cab rubber body parts had to come from Massachusetts and it took over 3 grand for all the window, door, cowel, fender and more pieces to get everything. I found some parts back east but they are not cheap.

      - 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.}
