FAQ

1. How do I confirm this DPT head rotor fits my pump?
First, locate the model number on your injection pump’s data plate. Then, cross-reference it with the OE numbers 28403729 or 28302134. The “4/7L” specification is a key indicator for the pump type. If you are unsure, please contact our technical support team with your pump model and engine serial number for verification.

2. What are the signs of a failing DPT head rotor?
Common symptoms include hard starting, engine misfiring, loss of power, excessive fuel consumption, and black smoke from the exhaust. A worn or damaged head rotor cannot maintain proper fuel pressure and timing, leading to these performance issues. Timely replacement is crucial to prevent damage to other pump components.

3. What is the recommended installation procedure?
Installation should be performed by a qualified diesel technician. The process involves disassembling the injection pump, carefully removing the old head rotor, and installing the new one with proper torque settings. It is critical to maintain absolute cleanliness to prevent contamination. We recommend replacing the pump’s seals and lubricating the new part with clean diesel fuel during installation.
