Hi Darren, a whining noise is usually air in the system. So no whining when you operate 3pt or remotes? Are you sure it is not the relief valve opening? The PS has a 1500 PSI relief valve and the 3pt and remotes have a 2500 PSI relief valve, Both are located on the MCV valve, on caseih.com 674 parts plate 10-18 item 6 is PS relief valve, item 25 is 3pt and remote relief valve. Re low oil to brake system, this again could be caused by PS relief valve problems because PBs are fed from return line of oil cooler, which is fed from PS flow. There is a screen and restrictor in the PB piping, see plate 14-01 item 24. There is also a flow and pressure test on the oil cooler return line.
