Cat 365c Hyd pressure

Movindirt345ME ยท 2014-06-19 17:10

Can anyone tell me what the main pump, swing pump, and power shift pressures should be at on a Caterpillar 365C? It seems to lack power just curious if there is something wrong or if its just me. Thanks. Serial# is CAT0365CCMCS00518

    Main pump signal relief is 4641 PSI Swing relief is 4200 pilot is 600 That's a start . You may want to check differential pressure too. Standby is 480 psi

    Thanks for the info. Main pump is only at 3900 relief. I will check the others Monday. The cat dealer is coming out tomorrow to check it out.

    Just an update. The Cat dealer turned the main relief up to 4700 where it is supposed to be and the issue seems resolved. The swing pump was just replaced on this machine so I'm not sure if that had something to do with the low relief pressure. Swing relief is at 4300.
