JD 950 hydraulic help

[jonezy00]

I have a JD 950, 13000 serial number range with an issue. The rate of drop lever somehow broke off and I found the part used in MO. I drilled out the broken screw. I also had to take the front rockshaft cover housing off to fix it, or so I thought. The shaft end that sits in the housing unit has a hole for a roll pin. I installed everything and now I have a slow leak from the front of the rate of drop lever. Any ideas on what to do now? Thanks.

It appears that the valve has a replaceable packing or o-ring. CH11560

This is the valve it is leaking from, see picture.

Tx Jim, that o ring seems ti have worked, thank you. I still have some hydraulic issues. When running the box blade or shredder, after about 30 minutes or so, the 3pt arms fall and I can't pick up the implement. I usually leave it, or drag it back. I've changed the hydraulic fluid (not JD brand, but JD approved) and the screen filter. It's back to being milky again after less than 5 hrs with the new hydraulic fluid. I can't locate any obvious leaks, and its parked under cover. Any ideas?
