Hi guys, new to TBN posting but been reading awhile. I have a nortrak 254 that I have modified the hydraulic system to eliminate the metric ORFS fittings and hydraulic hoses and generally clean up the hydraulic plumbing. I have also added a return line filter (10 micron donaldson) My question is, when the tractor is running and you are not using any hydraulics, how much hydraulic flow is returning through the return circuit. It seems to me that most of the flow would be returning to the sump through the TPH control valve and bypassing a return line filter. I think the diverter valve takes part of the flow for the steering and that would all return through the filter. Just trying to get a feel for how effective the added on filter should be. Any thoughts would be appreciated
