FAQ

Q1: How do I confirm this 9002-232L rotor fits my pump?
A: This part is a standard 4/7R DPA head rotor. Check the number stamped on your old rotor (it should read 641K or 9002-232L). Also, confirm your pump has a 4-cylinder, 7mm plunger configuration. If your original part matches these specifications, this unit is a direct replacement.

Q2: What is the installation procedure for this head rotor?
A: Installation requires precision and should only be performed by a qualified diesel injection technician. The process involves disassembling the pump head, removing the old rotor, and carefully pressing in the new one. Correct timing and alignment are critical for proper fuel delivery. We recommend consulting the pump’s service manual for exact torque values and procedures.

Q3: What is the shelf life and storage recommendation for this part?
A: The rotor is treated with anti-corrosion oil and has an indefinite shelf life if stored correctly. Keep it in its original packaging in a clean, dry environment at room temperature. Avoid exposure to extreme humidity or direct sunlight to prevent surface corrosion before installation.
