hydraulic Lift arm help

[BrettW]

Hi,
I have a hydraulic lift arm on my Yanmar that has stopped working. I know that often it is the switch that fails so I replaced it , but still no go. Can anyone give me advise on tracking down the problem? It was working fine and then just stopped. I was using it a lot moving my box blade around doing grading. Sure was nice while it was working.
thanks, Brett W

It could be the hydraulic oil filter plugged up....... /forums/images/graemlins/frown.gif

I would say it is probably electrical, that is if your 3 point is still working. I had a Hinomoto 2304 that had one of those that went bad, it was a frayed connection on a toggle switch.
