WOW!! I haven't had many of them. It was back at the College addition here in Speedy Creek. Finished off the grade beams. Last Friday's pour, which started in the morning was 47 yds, but it was very elaborate and involved 2', 4', and 6' stubs, this was all 2' and it amounted to 17 yds.
Job went pretty good, the hoseman liked it when I switched out to the 3" hose, it gives a good stream of concrete at a nice, slow pace.
Had a plug on prime, but I chased it down pretty quick. (The mud here seems to have gotten rockier???)
Clean-out wasn't the best, didn't get the second ball back, but that's happened before. Can't do much about it now, it'll be frozen in place in the pipe. (Note to self: soak the balls in a bio-degradable (RV) anti-freeze in the winter.) The measure of a pumper is how he handles these incidents. (Like a duck, calm and cool on the surface, paddling to beat hell underneath.) 
I'll just pump it out with water like I did the other times before, once I get it into a warm building to thaw. At least I have the peace of mind that the first one came back, the pipes are clean enough. I may have to try the trick about tying the 2 balls together. |
If you can't fix it with a hammer....you've got an electrical problem. |

Well I was going to have a Friday morning pour but it did not go as planned. Looked in the rear view mirror and this is what I saw. Not a good day.

What kind of sponges are you using? Last fall I had this happen because I sucked the good sponge first and the second didn't get suction. I went home and recirculated water found the sponge and all was good. I didn't have any hidden mud. Priming is an art as you know. Too much water or slick and she segregates.(42 has more pipe). I plugged the other day with my line pump because there was a little water in the hopper, it plugged in the reducer I knew where it was. That gallon of water got in the first hopper of mud and segregated enough
to rock out the mud and plug in the reducer. I usually put no water in the hopper just pour 5 gallons of bentonite in the hose. I good pumper even when he plugs knows where it is and gives a quick fix. I'm sure you handled it well. If it were easy?... |

| It is the output of the steibo box. Ripped the whole back out of it. Took the air lines out beat the hell out of the tool box and ripped this piece off the end of the drive shaft. Oh ya and broke a piece off of one of the hydraulic pumps. |

| Well it's off of my 37 meter Pumpstar. I have a wrecked 37 meter Pumpstar that I will take the Steibel box out of. It is a 10 year old pump so I am sure I will be paying for everything. Of course I am wondering what caused this. Have not had time to look at everything yet. I hope I find something as I hate putting things back together when I have not found a reason for the original failure. |

| It's good that you have a donor machine. Otherwise that would be extremely expensive. On the donor box, you'd bee well advised to change out the gear oil, just for good measure. Having to splice up all the airlines and other crap is the worst part of the whole deal. How about some pictures of your pump? |

Here is a picture of my pump. Use the loader to drag it around.
Here is a picture of the gear box. Checked the piece that came off bearing is still good so that was not the problem.

| It's likely a casting flaw. Too late now. If it would have happened when it was new, I'm sure the phrase 'shock load' or 'operator abuse' would have come up. |

| I wonder if a broken universal flopping around could have created enough centrifugal force and shock to bust that casing? |

Thank you, I try to keep it looking good. It is a 2000 Mack with a 2001 Pumpstar pump.
Well I many have found the smoking gun. The bearing cups on the u-joint that is on the output of the box (piece that came off) are turning in the yoke. I took them off and after cleaning them up they are very loose in the yoke.

06savana,
One thing to double check is the Balance of the driveline. Do you recall any vibration when you were driving the truck or Pumping? The housing is not built to take the constant vibration from an out of balance drive line. They can throw the weights, get damaged from years of use or in an extreme case I have been told about one that had 5 Lbs of grease inside the tube, So Make sure you consider this.
