FAQ

Q1: How do I confirm this rotor head fits my injection pump?
A: Please check the existing part number on your pump’s rotor head. It should read 146401-0221. Also, verify the “4/10R” marking. “4” indicates a 4-cylinder pump, “10” is the plunger diameter (10mm), and “R” signifies a right-hand rotation pump. If your pump matches these specs, this part is compatible.

Q2: What are the signs of a failing rotor head?
A: Common symptoms include hard starting, engine misfiring, rough idling, a decrease in fuel economy, black smoke from the exhaust, and a lack of power under load. A worn rotor head cannot maintain the high pressures needed for proper injection, leading to these performance issues.

Q3: Is professional installation recommended?
A: Yes, absolutely. Replacing the rotor head requires disassembling the VE injection pump, which is a precision task. It involves strict cleanliness and specific timing procedures. We strongly recommend installation by a qualified diesel fuel injection technician to avoid pump damage and ensure proper engine timing.
