FAQ

Q1: Is this head rotor a direct replacement for my Toyota VE pump? Will it fit without modifications?
Yes, this part (146403-4920) is an exact OEM replacement. It is precision-machined to match the original specifications of Toyota VE-type injection pumps. No modifications are required for proper fitment.

Q2: What are the signs of a failing head rotor in a VE pump, and how often should it be replaced?
Common symptoms include hard starting, engine misfiring, reduced power, excessive black smoke, and fuel leaks from the pump. As a high-wear component, it is typically replaced during a VE pump overhaul (every 150,000-200,000 km or when pump performance degrades).

Q3: Do you provide installation instructions or technical support?
We offer 24-hour customer service for technical inquiries. While professional installation by a qualified diesel mechanic is recommended, our team can provide guidance on installation procedures and torque specifications upon request. Proper cleaning and timing alignment during installation are critical for performance.
