Frequently Asked Questions

Can a CAT hydraulic pump's rotation direction be reversed?

No, most CAT pumps are designed for fixed clockwise rotation (viewed from the drive shaft end), and reversing may cause internal damage.

What is the role of a pilot pump in CAT equipment?

The pilot pump supplies low-pressure hydraulic oil to control valves, enabling operator control of equipment movements (e.g., boom lift, bucket tilt).

How often should CAT hydraulic pump filters be replaced?

Follow the equipment maintenance schedule—typically every 500-1000 operating hours, or sooner in harsh working conditions.

What is the application of CAT pump part number 307-3063?

307-3063 is an axial piston pump designed for CAT loaders/backhoes (e.g., 415F/416F), not for excavators.

What temperature range can CAT hydraulic pumps operate in?

The optimal operating temperature is 50-80°C; prolonged operation below 10°C or above 90°C will reduce pump life.
