CNH sells the same industry stanbard o-rings you will get from any industrial supply house. Not sure about the 600 cam follower but the NAA pin was an oddball (under)size so you may find CNH a safer option. For the legacy machines CNH often sells the same aftermarket parts as the other suppliers so there is no guarantee it will be "special".
The hydraulic high pressure connection(s) to the top cover is via a face seal port in the center housing and is sealed by the o-rings.
