Q: What should be checked if a new 4469025 main pump fails to build pressure upon installation?
A: Ensure the suction line is completely free of air pockets and that the pump was pre-filled with oil. Check that the pilot control pressure lines are hooked up correctly, as a faulty pilot signal will keep the AP2D36 pump at minimum stroke.

Q: How do the wear characteristics of this pump compare to cheaper aftermarket alternatives?
A: We use premium bimetallic valve plates and hardened pistons that significantly outlast lower-grade alternatives. This prevents early scoring and reduces internal bypassing, saving you money on early replacement costs.
