FAQ

Q1: Is this VE rotor head a direct replacement for my 4JB1-TC engine’s injection pump?
A: Yes, this part (146402-4720 / 9 461 624 616) is specifically designed for the 4JB1-TC engine. It is a standard-size head rotor that fits seamlessly into the VE-type fuel injection pump. We recommend comparing your old part with the dimensions (15x13x10 cm) to confirm physical fitment.

Q2: What are the common symptoms of a worn rotor head that requires replacement?
A: A failing rotor head can cause hard starting, irregular engine idle, loss of power, excessive black smoke from the exhaust, and reduced fuel efficiency. If you experience these issues with your 4JB1-TC engine, replacing the rotor head is a critical step in restoring injection pump performance.

Q3: Do you provide technical support for installation?
A: While we do not provide direct installation services, we recommend that this component be installed by a qualified diesel mechanic with experience in VE pump systems. Proper cleaning of the pump housing and precise alignment during installation are essential for optimal performance and longevity. Our team can assist with part identification and general fitment questions.
