      2005 Mack e7 turbo speed code

      By Mackpro · Posted

      Oil sludge is common on the intake side of the turbo. This is caused by not changing the air filter soon enough. The air compressor gets its fresh air from the pipe between the air filter housing and the turbocharger, when the air filter is dirty the suction from the turbo impeller will pull oil past the air compressor rings and it will settle and turn to sludge in the intake side of turbocharger. There are some bulletins on fixing the problem with a check valve and special hose on the air compressor intake piping. The fault code for the turbo wheel speed was an open circuit code so the engine ECM is not seeing a signal from the speed sensor. Usually a bad sensor or wiring between sensor and ECM. Test 4 in what Joey Mack posted would tell if it’s the sensor. Only weird this I ever saw was the turbo impeller shaft broke between the bearing and you could turn the intake impeller one way and the exhaust the other way.

      300+ rebuild

      By Freightrain · Posted

      IT MOVES!!!!! I installed the new pump(another story) and got it running.  I was able to air it up, release the brakes and was able to push the clutch and easily slip it in gear and slowing inch the truck forward(can't go far).  I pushed back down on the clutch and slipped in reverse and backed it up.  Nice!!!! I released in neutral a few times and pushed down fully and was able to slip it in gear without any clash.  I did it numerous times in forward and reverse. I then pulled the linkage all off, drilled the pivot bar for a cotter pin to capture the Z bar.  I installed the grease zerk in the bar and put a couple clicks of grease in it and spun it around a few times to work the grease into the bushing.  I then bolted it in for the last time and attached the clutch rod to the transmission. Now I need to recut the keyway in the pedal pivot rod and finish the machine work.  Install pinch bolt detail and then split the ring.  I need to install the bracket for the return spring.  I am pretty sure I can modify the original bracket and weld it to my new arm to enable the stock spring to be used.   Not onto the new pump.  Ugh.  I installed it and the given primer pump didn't work(ya, I knew that was coming).  I installed the old bailing ring pump from my 237.  It still had issues getting fuel up.  I still have the pressure gauge installed in the fuel filter housing to watch.  I finally got it primed and engine as started.  The 20# I pumped up slowly dropped off like before.  I pumped it while running and it went back up to 20#.  Then slowly dropped again. I removed the return check valve assembly and investigated it.  Nothing wrong I could see.  Sealing surfaces were fine. I thought maybe I could shim it up.  I had some .010 shim stock and cut a piece and put it back together.  I could pump 30# now.  After starting it would again just slowly drop off.  Less of you didn't rev the engine.  It would idle for as long as you wanted.  I did finally get some heat in the engine and topped off the radiator. Tomorrow, after getting the other power steering lines made I am going to make a short fuel line and run it off a can and see if it keeps pressure.  If not I am not really sure what to do next. I tested the Jakes, they work. After I get the clutch parts in for good, I can put the floorboard back in so I can tidy up the interior and keep moving forward on the front end.

      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.
