FAQ

Q: How do I confirm this plunger will fit my injection pump?
A: Verify your existing plunger’s OEM number against the list (A136, A311, A264, A274, A182). If your part number matches one of these, it is a direct replacement. For pumps without a visible number, measure the plunger diameter and length to compare with the P-Series specifications. We recommend consulting your engine or injection pump manual for confirmation.

Q: What maintenance is required after installing a new plunger element?
A: After installation, prime the fuel system to remove air and check for leaks at the pump connections. It is critical to use clean, high-quality diesel fuel and replace the fuel filter simultaneously to prevent contamination. Regularly inspect the plunger for scoring or wear during scheduled engine maintenance (every 500-1000 hours of operation).

Q: Can this plunger be used in non-excavator engines?
A: Yes, while it is commonly used in excavators, this P-Series plunger is compatible with any diesel engine that uses the same OEM part numbers (A136, A311, A264, A274, A182). This includes certain truck, agricultural, and industrial diesel engines. Always cross-reference your specific engine model and injection pump type to ensure a proper fit.
