Ford 5610S - Hydraulic oil leaking from valve on top of the lift cover...

[Lykins Farm]

I have a 1995 Ford 5610S that is leaking hydraulic oil from the valve on top of the lift cover, just up under the seat. How difficult of a job is this? Any part numbers for what will be needed?

I also have a leak on the rear remote coupler where two plugs go. One plug is missing as can be seen in the photo. I ordered a new one from local CNH store and installed it but it will not fit with the o-ring they provided and the plug keeps falling back out. The plug is a snap-in plug. Please see photos attached and please let me know if you have any tips or suggestions on this. I am not real familiar with hydraulic systems.

Can't tell exactly where the leak is on the unload valve, but disconnect the lines, unbolt valve and reseal with new orings if the leak is under the valve. #8 orings are all used, different sizes with the quantities listed necessary.

On the coupler, the plug is an upgrade cover that covers the hole in the housing when a lever was used to release the couplers. They eliminated the lever and came up with the plug and oring. The oring should fit inside the recess. The plug must be staked in place.

The unload valve is leaking out of the front side where it mounts to the lift cover. Thank you so much.
