      Old lowboy walking beam suspension questions?

      By seyser · Posted

      I spoke with a local truck/trailer place that does this stuff everyday and they haven't seen one like this. They expressed the same concerns with not having the axles tied together. They mentioned replacing bushings wouldn't be a problem but didn't think it would ever stay in alignment with the way its designed. The trailer paint is original and I still see it on the axle stubs so cant tell if it left the builder this way or they were cut later at some point. I cant imagine a reason anyone would ever do that though. Its a nice straight rust free trailer but I will probably keep looking at this point. I appreciate all the comments and insight on this!

      Old lowboy walking beam suspension questions?

      By mrsmackpaul · Posted

      I have never seen a axle ser up like this, however it should be all fixable  I'm sure that line boring must be common in the U.S. like Australia  We can get line boring people to come to site, whether it's your back yard or down paddock or on some building site in the middle of a big city They can weld the pivot bores up and then make them perfectly square with the trailer and then bore the holes out And then match the walking beams perfectly with the trunions, the bit welded to the trailer And presto, it's like new again, providing you keep it greased up ot will out last all of us   Paul

      Old lowboy walking beam suspension questions?

      By Geoff Weeks · Posted

      It may explain why the trailer didn't get used much. If I had time an money to put into it, there are a couple ways to "fix" it. One would be to cut out the axles and replace. The other would be to weld structural tubing back in where they cut the axle. Problem is with either method you are going to have a lot of welding that has to be done correctly and the axles have to be in perfect alignment when welded as there is no adjustment possible. You can't just slide a new axle in unless you get one with no brake spider on it and the weld a spider on.  Lots of making sure everything is correct before welding.  You can cut out the back of the box beam and install an axle but then have to re-weld in the box for strength.  You can re-bush the center pivot which would help but not solve all the issues. Easiest method for a good "pipeline" welder would be to weld tube back where it was cut out.

      300+ rebuild

      By Freightrain · Posted

      The two times I have spoken with a pump shop I got the same glazed over eyes look when asking for "a little more".  Either I have to give them the whole spec sheet, or nothing happening. I still have the printout from 25 yrs ago and FJH gave me the how to on my Robert Bosch pump on my old 673(and my 237).  I don't have any info on this "P pump".  Is there a simple rack setting that I can move a jam but a couple flats?

      300+ rebuild

      By tjc transport · Posted

      Many years ago I had an injector line leaking. While replacing it, I noticed the turbo was leaking oil and a bearing was loose. So I changed the line and was going  to order a turbo the next day. Anyhow, #5 injector  died. Since there no 237 injectors in the shop I put a set of 300 injectors in and 300+ 5 inch turbo replaced the 4 inch of the 237. We had to turn the injector pump up quite a bit to make it run properly, but I could keep rite there with newer 400 hp truck with 8ll Transmissions.  The only time I would loose ground was on long hills.

      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.}
