My 7753 started making a different hydraulic noise, lets call it a whine. Now when she goes into a pile it doesn't have the power it had in both the bucket hydraulics and the drives. The engine is not bogging down. It just is not there. When I replaced the filters the two metal return line filters had metal chunks. Bad sign!, I am open to suggestion where to start. I am working on a flow meter/pressure tester to test the auxiliary pump. Besides that i am trying to figure out what else could make both the drives and the bucket hydraulics loose power. But for the life of me I don't understand why the aux pump would affect the drives. Having this thing down is a serious bummer I use it for everything.:weepy:
