FAQ

Q1: Is this plunger element a direct replacement for my Fordson 4000 tractor?
A: Yes, this part (512506-53) is specifically designed for the Lucas CAV injection pump used in Fordson 2000, 3000, and 4000 series tractors. It is a direct fit and requires no modifications. We recommend verifying your pump’s model number to ensure complete compatibility.

Q2: What is the recommended installation procedure for this plunger?
A: Installation should be performed by a qualified diesel technician. The plunger must be thoroughly cleaned and lubricated with clean diesel fuel or light oil before insertion into the pump barrel. Ensure the pump housing is free of debris. Over-tightening during assembly can cause distortion. Always refer to the service manual for your specific Lucas CAV pump for torque specifications.

Q3: What is the typical lifespan of this plunger element under normal operating conditions?
A: The lifespan depends heavily on fuel quality and maintenance. With proper fuel filtration and using clean diesel, this high-speed steel plunger can last for several thousand hours of operation. Signs of wear include hard starting, reduced engine power, and black smoke. Regular inspection of the injection pump components is recommended during major engine overhauls.
