FAQ

Q1: How can I confirm this head rotor is compatible with my Perkins engine?
A: Check the part number on your existing fuel injection pump head rotor. If it matches 7123-340U, 7180-550U, or 344U, this part is a direct replacement. For further verification, consult your engine’s service manual or contact us with your engine model and pump serial number.

Q2: What is the typical installation process for this head rotor?
A: Installation should be performed by a qualified diesel technician. The process involves removing the fuel injection pump, disassembling the pump head, replacing the old rotor with the new unit, and reassembling with proper torque specifications. It is critical to maintain cleanliness and use new seals during installation. We recommend referring to the manufacturer’s service manual for detailed steps.

Q3: How should I store spare head rotors to maintain their quality?
A: Store in a cool, dry environment away from direct sunlight and moisture. Keep the part in its original packaging until ready for use to prevent contamination or corrosion. Avoid exposure to extreme temperatures or chemicals that could degrade the high-speed steel material.
