Diesel Plunger and Barrel Assembly A149
The Diesel Plunger and Barrel Assembly A149 is a matched pair designed for use in high-pressure diesel fuel injection systems, where precise metering and sealing are critical. The plunger has a nominal diameter of 6.8 mm and the barrel inner bore is honed to 6.805 mm, creating a clearance of 0.005 mm, which is standard for this assembly type. The pair is manufactured to maintain concentricity within 0.002 mm over the full length.
The assembly is made from high-carbon chrome steel, hardened to 58-62 HRC, and both components are nitrided to enhance surface durability. This is consistent with industry norms for OEM-grade fuel injection parts. The barrel features precision internal grooves for fuel distribution, and the plunger has a helical control groove designed to regulate fuel delivery timing. The pair is assembled without shims, relying on matched grinding tolerances.
This assembly is commonly used in medium-duty diesel engines for trucks, generators, and marine auxiliary systems. Buyers typically purchase in quantities of 25 to 100 units for repair shops or fleet maintenance operations. Packaging is in individual anti-vibration foam inserts within cartons of 25 units. Lead time and Incoterms are confirmed upon request, with FOB Fuzhou being the default term. No certifications are claimed, but quality control is stated as rigorous.

Sourcing Diesel Plunger and Barrel Assembly A149 from Chen Chen Diesel Parts Plant - China Import Guide
Before ordering, verify the plunger-barrel clearance and concentricity specifications against your existing units. Request a sample pair for fit testing in a test pump. Confirm that the groove profile matches your engine’s injection timing requirements. Do not rely on part number alone - dimensional drawings are essential for compatibility.
Lead time is not specified and must be confirmed directly with the supplier. Delivery terms are typically FOB Fuzhou port, but CIF or CFR can be arranged. Payment is commonly via T/T, with 30% deposit and 70% against bill of lading. Request a commercial invoice with HS code 8409.91 for customs clearance in your country.
Upon receipt, inspect each assembly for surface scratches, deformation, or corrosion. Use a micrometer to verify plunger diameter and barrel bore. Perform a leak test using diesel fuel under 150 bar pressure. Retain a sample set for future quality audits. Request a material certificate if available, though none is guaranteed from this supplier.
