FAQ

Q: What is the specific function of the DPT Rotor Head (28403730) in a diesel injection pump?
A: The rotor head is the central rotating component within a DPT-type distributor injection pump. Its primary function is to meter and distribute high-pressure fuel to the correct engine cylinder at the precise moment. A worn or damaged rotor head can cause poor engine performance, hard starting, and reduced fuel efficiency. This replacement part restores the pump’s ability to deliver fuel accurately.

Q: How can I confirm that Part Number 28403730 is the correct fit for my injection pump?
A: To ensure a correct fit, please verify the part number stamped on your existing rotor head or consult your pump’s service manual. This part is a standard-size replacement for DPT pump assemblies that use the 28403730 rotor. If you are unsure, please provide your pump model number or engine specifications to our sales team for verification before purchase.

Q: What installation steps or precautions should be taken when replacing this rotor head?
A: Installation should be performed by a qualified diesel technician. Key steps include: thoroughly cleaning the pump housing, lubricating the new rotor head with clean diesel fuel or assembly lube during installation, and ensuring all mating surfaces are free of debris. It is also critical to prime the pump and check for proper timing after reassembly to prevent damage. Always refer to the manufacturer’s service manual for your specific pump model.
