FAQ

Q1: How can I confirm this AP2D28 pump is the correct fit for my EC55B or EC70B excavator?
A: We recommend checking the part number on your existing pump. It should match “AP2D28” or a direct cross-reference. Additionally, verify the pump’s mounting flange pattern, shaft size, and port configuration against your original part. If you are unsure, please provide us with your machine’s model and serial number for a fitment check.

Q2: What is the difference between a hydraulic pilot pump and a main hydraulic pump?
A: The main hydraulic pump supplies high-pressure oil to power the excavator’s primary functions (boom, arm, bucket, travel). The pilot pump, like this AP2D28, generates lower pressure oil used to control the main control valves. It is essential for precise, low-effort operation of the joysticks and pedals.

Q3: What maintenance is recommended for this pilot pump?
A: Ensure the hydraulic system’s oil is clean and at the correct level. Regularly change the hydraulic oil filter and return filter as per your machine’s maintenance schedule. Contaminated oil is the primary cause of premature pump wear. If you notice slow or jerky machine controls, check the pilot pump pressure first.
