9300 Backhoe hydraulic relief valve

Post by KSS Const. » Sat Mar 04, 2017 1:31 pm

I have a dripping relief valve on my 9300 Backhoe. The valve is designed to dump fluid on the ground under over pressure conditions like if the return line is clogged. John Deere no longer makes a replacement. It screws into a 3/4" NPT plug. Any ideas for a replacement or retrofit?

there is aftermarket relief valves available. You just have to watch the relief valve pressure settings when ordering a new one. There is various pressures available.

I looked for aftermarket with no luck. Could you give me some direction where to look?

JD has a repair kit AT52174 $5.24 for your relief valve I think I would try that first .
