hi I just purchased a 2012 pc360-10 with 9500 hrs on it , oil tank is just below sight glass, new hydraulic filter, strainer in new , hyd pressure are where they should be according to specs, runs good and digs great , but when I go to track it the pump starts cavatating badly , till I drive for 5 seconds it stops , and sometimes when I put pump under big load (demanding lot of oil) I hear it also , I checked the hyd tank vent and it looks clean . Got me very puzzled and wonder where I could start looking . It needs to be fixed , cause once it does it when I track it I can make it do again when lifting boom, but when it sits awhile and I don’t track it but just dig , it hardly does it. Please and help will be appreciated , I haven’t checked the strained on top of the pump inline . Almost looks like the track side or hydraulic collecting ring let air in and areates the oil . But can’t really find a leak , not a bad one . Hope pump isn’t shot , but I doubt it as it is very fast and has lots power . 5400 psi on front and rear pump , about 2000 ish when tracking but when turn goes over 5000 psi.
