I have a 460 loader attached to my 4700. For a few years, the loader holders (I call them paddles) do not move in sync. Referring to the attached diagram, I find that the synchronizing bar (#8) doesn't do its job. The whole bar twists (30+ degrees) since there seems that one of the holders doesn't move as quickly as the other.
At times, the cotter pin (#4) breaks, but even if I use a steel nail, I still can't get the holders to move in unison – or to line up. The bar just remains twisted.
As you can imagine, it takes a bit of finesse to attach my bucket or forks.
I am wondering what I can do to get the two holders to move more closely in unison so that they don't stress the bar or break my cotter pins? It is like the hydraulic pressure is different on both sides of the loader boom?
Or, do I need a new bar? They are quite expensive so I would rather avoid buying one to find out it doesn't work.
