400X loader masts loose

[arlen4720]

I've got only about 300 hours on my 4720, with about 200 of it being moderately hard loader work. I do keep my adjusters tight, and everything is nice and solid... so far. If/when mine does start to loosen up I would probably just weld up the wear areas and/or drill a 3/4 inch hole thru the mast and put a 6" bolt through the casting. I seldom take my loader off, and and agree that it would be nice to have a nice beefy non-QA loader option for the 3x20's and 4x20's.

I tightened up the adjusters with the loader lifting the front tire off the ground... really snug now. One more thing to keep an eye on when checkin things.

The 400X loader on my 4520 started to be loose and tightened with no improvement. Looking carefully at the 3" pipe welded as a cross frame front of tractor this had broken and allowed the frame to shift with a load.
look inside of loader arm where the pipe is welded mine had cracked and was shifting when standing on one side of bucket.

Not saying this is your problem but it was mine. after rewelding the frame has remained solid on the supports.
