John deere 8430 hyd weak

Posted by Lynn s on May 18, 2018 at 11:08:56 from (64.203.189.236):

We have a 4wd 8430 that has weak hyd after oil heats. Changed filters but no change then put a gauge on scvs and pegged the gauge but as soon as you use another function steering 3point ect the flow all but quits. Have pressure but not much capacity not sure if the charge pump is supplying enough to the main pump. What direction should i start in. Thanks
