FAQ

Q1: Is this rotor head a direct fit for my CAV DPA pump on a Toyota 3L engine?
A: Yes, this part (7139-764S / 7180-616S) is designed as a direct replacement for the rotor head inside a CAV DPA pump used on the Toyota 3L engine. It is a critical internal component; we recommend confirming your pump model and rotor part number before installation.

Q2: What are the common signs of a failing fuel pump rotor head?
A: Symptoms include engine hard starting, low power, black smoke, irregular idling, or fuel starvation. A worn rotor head will cause poor fuel metering and pressure loss. Replacing it with a new, tested unit restores pump performance.

Q3: Do I need special tools to install this rotor head?
A: Yes, replacing a rotor head requires specialized knowledge of diesel injection pumps. It is not a simple bolt-on part. We strongly recommend installation by a qualified diesel injection technician who can properly disassemble, clean, and calibrate the pump after replacing the rotor head to ensure correct timing and pressure.
