[QUOTE="skidsteer.ca, post: 7160, member: 307"] The case drain returns to reservoir whatever oil is bypassing within the motor and not returning to the hydrostat pump and being pumped back to the motor again. The charge pressure has to replace the oil coming out the case drain. Whats excessive now, I don't know but it should be no more flow then that tiny line can easily handle, and should be compareable side to side. And yes dropping the boom quickly on my 553 sent charge pressure sky high, like adding a second charge pump Ken [/QUOTE]
