FAQ
Q1: How can I confirm this grow plug will fit my Mitsubishi engine?
A: Please verify your specific engine model (6D31, 6D34, 6D14, or 6D16). This plunger is designed for the fuel injection pump of these engines. For absolute certainty, we recommend comparing the dimensions and design of this plunger with your original part. If you have the specific OEM part number from your fuel pump, please contact us for cross-verification.
Q2: What are the signs that my fuel injection plunger needs replacement?
A: Common symptoms of a worn plunger include difficulty starting the engine, excessive black or white smoke from the exhaust, a noticeable loss of engine power and torque, rough idling, and increased fuel consumption. If you experience these issues, inspecting and replacing the plunger and barrel assembly can often resolve them.
Q3: What is the correct procedure for installing a new plunger?
A: Installation of a fuel injection plunger is a precision task that should be performed by a qualified diesel mechanic. The process involves carefully disassembling the fuel injection pump, cleaning all components, and replacing the old plunger and barrel assembly. It is critical to maintain absolute cleanliness to prevent contamination. The pump must be re-calibrated and timed correctly on a test bench after installation to ensure proper engine operation.
