Where is the suction screen? Also I don't believe it is the filter either as the tilt works perfectly also the machine drives fine

The suction screen is in the tank , at the pick up hose,

any time you get whining noise from the pump,

it is from lack of oil ,you other functions may work as use less pressure

How often do you change the Hyd Oil and filter
