FAQ

Q1: What is the function of the rotor head (146405-4420) in a diesel injection pump?

The rotor head is a central component in a distributor-type fuel injection pump. It rotates and distributes high-pressure fuel to the correct engine cylinder at the precise moment. A worn or faulty rotor head can cause misfiring, power loss, and poor fuel economy.

Q2: How can I confirm that this 146405-4420 rotor head will fit my pump?

Please verify the part number on your existing rotor head. This part is specifically designed for pumps that use the 146405-4420 number. If your pump is a 6/11R type and uses this standard rotor head, it will be a direct fit. We recommend consulting your pump’s service manual for confirmation.

Q3: What is the recommended procedure for installing a new rotor head?

Installation should be performed by a qualified diesel technician. It involves disassembling the injection pump, carefully removing the old rotor head, and cleaning the mounting surface. The new rotor head should be installed with the correct torque specifications and the pump must be re-calibrated on a test bench to ensure proper fuel delivery and engine timing. Always use new seals and gaskets during installation.
