763H High flow control valve leaking

[pknoeber]

I've got a 763H with the high flow hydraulics, and it's leaking from the high flow hydraulic control block. I couldn't determine exactly where, so I just replaced all the o rings hoping one of those was the culprit. It's still leaking. It has what looks like pressure relief weep holes with steel balls or something held in place... I honestly don't know what they are, but I'm starting to think those might be the problem. Anybody know where the leaks usually come from on that thing?

The steel.ball is a plug for a drilled passage way in the block. I have seen similar components leak from those. Our option was to replace the part. A machine shop maybe able to do something cost effective in replacing that plug, but I never tried that route.
