Subject: Pressure at Rawson motors only 500psi


I used this setup (kinze 16 row, 2 rawson motors, cih 7140 tractor) last year and it worked ok, but it almost looked like it pulsed a little once in a while. The rawson lady said I should be running 1500 psi, but even with the flow turned up it won't do it (500psi is about it). All the hydraulic functions work fine otherwise (no lack of flow or pressure). On each rawson motor I have the following:

Relief cartridge: RV08-22H 26/10
check valve cartridge - CV08-20 04 9641 (last 4 are a part number maybe?)
flow control cartridge - FR10-20F 4 GPM 9649

Last year some guys thought that maybe I have the wrong oriface - which one would I change and what would I replace it with?


thanks very much,

Pat
