By the way guys when I pull back on the lever to raise the upper part of arm the pump is struggling to move fluid an the ram extend about 1/2"

Just curious, with everything you are saying, have you xhecked your hyd filter and hyd levels? Really sounds like you are really low on fluid or partially blocked in filter.

The first thing to check on the backhoe is if all the quick couplers are tight. If you have a coupler which is not fully engaged, that will restrict flow to zero or almost zero and it is not easy to see. Just to be sure, take off all quick couplers and reconnect to eliminate that as a problem before you do any further work. May not be the problem, but takes 5 minutes and could save you lots of work. Post on safety lock pin is a good one, too. There is usually a vertical lock pin.

"The ball on the lower end of the lever arm that actually pushes the valve down has broken off, the backhoe can be operated with the cover plate off because the lever can be pulled further back , my torches are up on the mountain, I have only a wire feed at the lower ranch,

I'll see what the tractor shop down here can do might be reasonable"

Glad to hear the root cause has been identified and looks to be a not to complicated fix.
