  • Rebuild of Wagner F.E.L. hit a snag.
  • If any of you were following the rebuild remod of our Wagner front end loader will remember I was looking to replace the pump with a new one. I ordered the 1.95cu pump. It arrived a couple of weeks ago, and I finally got it mounted and all new lines made for the whole system. When it was done it looked like a factory assembly. I was real proud and happy with the way every thing looked. I put in new fluid,bleed all the air out that I could before I started it up, when I started it up and started working all the cylinders to get the rest of the air out,Everything looked good for about 2 minutes then everything stopped. The pump totally stopped working, so I had to take everything apart again, I found the keyway sheared, it appears the pump seized, I noticed the pump turned hard before I put it on, but thought that was because it was brand new. I didn't even get it of my shop I hope they warranty the pump, but that doesn't help with all the work I had to do to put it on take it off and now put a new one on. God Bless,Beth and Allen.

  • Sounds odd - pumps dont typically self destruct in a matter of a couple minutes like that. Sheared key suggests over pressure condition or loss of oil supply. Are you sure you have everything plumbed correctly?

  • Hi Old Hokie I primed the pump before I hooked up return line to it,and bleed all the air out that I could before I tried anything. There was nothing on the loader,or in the bucket. I was only running engine about 600 rpm, I was running the lift arms up and down and working the bucket up and down to purge remaining airI only got one cycle on each before it quit. All lines are hooked up properly,When I took the new pump off it had oil in it. Today I dug out the old original pump, took it apart and cleaned it up and reassembled it with new gaskets. I put it on and did all the same pre start priming and bleeding and cycled thru every thing several times and even pushed levers to where cylinders were at their limit to see if anything broke. Nothing did, although I do have a couple of small leaks where fittings need tightened a little more,the old pump works ok just a little slow in my opinion. As I said in my original post I felt the new pump turned hard which I thought was due to being brand new,but the old pump turned very easily by hand after I reassembled it where as I had to put something on the shaft of the new one to turn it now it is seized :( .God bless, Beth and Allen.

  • I've used 50 or so of those pumps in various displacements and both SAE-AA and SAE-A form factor. The only one that ever had a problem had been field modified to reverse the rotation and leaked from the outset. I dont know if the modification was done by Burdens or by the OEM but the part number was restamped to indicate the change. Check the model number stamped on the top of your pump. It should end in "PA" indicating keyed shaft and anti-clockwise rotation. If that "A" has been restruck or the directional arrow on the top indicates clockwise rotation that pump has been disassembled and reassembled by someone after it was manufactured.

  • Thanks, I'll check that out.It will have to wait till next monday or tuesday now.Those are my days off, I'm not looking forward to this week, they have me hauling etanol,3 loads a day out of one of the most dangerous parts of Philadelphia,wish I was allowed to carry my 9mm. I'm kind of surprised the company isn't hauling gas into the city because it's too dangerous but I'm hauling ethanol out.God Bless, Beth and Allen.

  • I have two Wagners (or did, my son has claimed one). They are not a closed system. Air is automatically bled as you cycle the cylinders. The resevoir is vented.

  • Thanks, yes I know about air bleeding out as their worked,but since I had the whole system open and totally replaced all lines and even flushed the frame(tank) and a brand new pump I wanted to make sure it had every chance of working right,that is just the way I do things. God Bless,Beth and Allen.
