Broken Fork on Forklift

A Front Loader Fork lift had a broken fork.  Some folks say they don’t have much luck with welding the fork on  a forklift back together.  I do my best to not depend on “luck” to determine what I can or cannot do.  There is a specific procedure to weld these together.  First you must make certain the forks are parellel and they are lined up right.

Then preheat the forks to ensure the weld does not cool down too quickly as the forks are being welded.  It is critical that the filler rod is tougher than E7018 because the forks are typically a medium carbon steel and tougher than mild steel, I used E10018.

Here I used the back of my truck to align the forks, as if the truck needed the additional weight on it, it held up alright.

Sloppy Pivot Pins on Large Front Loader

 

Chatfields in Sacramento, CA has an old large front loader.  They had an issue with the pivot pins in the lifting arms and dump arms breaking the keeper bolts and the pins evenually starting to slide out.

  They wanted me to just weld the pins in place, however that would not have solved their problem.  The pivot pins where getting loose because either they were wearing out or the bushings were wearing out.  In other words the hole the pin was in was either to large for the pin because the bushings were worn out or the pin was too small due to it being worn out.  If I had welded the pin in place the welds would have eventually broken due to the stress on the pin from working in a sloppy hole.  The correct fix was to replace either the bushings or the pins or both.  The field quick fix is to weld something to the opposite side of the pin so the pin cannot come out.  I had some 1/2″ x 1/2″ solid square bar on my truck and used that as the keeper so the pin would not slide out.  I just welded the square bar to the pin so the pin was not locked in.

Repaired Aluminum Oil Filter Bracket

I was at Chatfields in Sacramento, CA.  They have a large front loader and the Aluminum Oil Filter Bracket was broken.   Asked if I could fix it and sure enough I had no problem.  I never know what I will need when out on repair calls so its nice that I can have just about everything on my truck for what ever I need.
