Trailer Jack #2

After two days of working on the old jack I have given up.  The screw is seized so badly into the jack that there is nothing I can do.  The aftermarket jack is just to dangerous to keep using so I will need to replace it. I really like the idea of using the welded on snap ring mount so that I can put a spare tire mount on the drivers side of the trailer.  I found jack that should work with the weld mount and is not too expensive.

Trailer Jack

The trailer has two jacks on it.  One is the factory Attwood jack that is welded to the trailer.  This jack does not work.  It is missing the caster wheel, it will not rotate on the trailer mount and it will not move up and down.

The second jack is aftermarket and is also in bad shape.  When the weight is on the jack the top of the jack will move back and forth around 2 inches.  The previous owner broke his foot when that jack broke and the trailer feel on his feet.  So, basically I don;t trust the second jack and have the trailer's weight resting on a log. 






   I first sprayed the Attwood jack in PB Blaster then I was able to pry the rotating pin out and start loosening the jack's swinging motion.  Next I tried turning the crank to see if the jack would go up or down.  Unfortunately the jack just spun in place and did not move up or down.  I took the Attwood jack off by removing a big c-clip.   To disassemble the jack I punched out the pins that hold on the two gears.  This freed up the inner tube of the jack.  At this point I could see that the screw the gears turn was seized inside the inner tube.  Tonight the jack will soak in PB Blaster and hopefully I can work it free in the morning.
