I concur with Bruce --- pull the whole pump and clean & rebuild it to do it right. Also, when draining hydraulic oil always go from back to front. Remove the NPT diffy plug first. It has 9/16" square NPT plug on it. The trans and hydraulics are all in the same sump. You need to always put the pertinent info in your post each time like make and model of your tractor. I, and I'm sure many others, don't keep tabs on, let alone remember what each member has, so let the reader know which system you are referencing. There are differences. See the LINK for info on a Ford 9N/2N hydraulic system rebuild. Note the 8N is different - no wishbone bracket, but they explain all that with the 8N control rod.
