original 250-1311 Fuel Injector Fit 3516B 3512B 3512C 3516C C3500 Excavator Diesel Engine 3 Months Warranty  original new injector

The 250-1311 fuel injector is engineered as a direct-fit replacement component specifically calibrated for the 3512B diesel engine platform. Manufactured to OEM specifications, this high pressure diesel injector integrates seamlessly into the cylinder head assembly of 3512B, 3512C, 3516, 3516B, 3516C, and 3508 engine configurations. The component is recognized across multiple industrial sectors including power generation, marine propulsion, mining, and oil and gas operations, where consistent fuel delivery directly influences engine reliability and operational uptime.

Precision CNC machining ensures micron-level tolerances across the injector body and internal flow paths, while the multi-hole nozzle design optimizes fuel atomization for uniform combustion across all cylinders. Critical wear surfaces undergo specialized heat treatment processes to extend operational life under continuous industrial duty cycles. Corrosion resistant material selection makes this injector suitable for marine and offshore environments where exposure to humidity and salt-laden air can compromise standard components. Cross references including 10R0957, 10R0958, 10R0960, 190-4976, and 236-3271 confirm broad interchangeability within the 3512B engine family.

Each injector is individually tested for flow rate, spray pattern, and pressure performance before shipment, backed by a 12-month warranty covering manufacturing defects. Proper installation following service procedures—cleaning the injector bore, replacing sealing washers, lubricating O-rings, and applying specified torque values—ensures optimal performance. The result is reduced fuel consumption, improved transient load response, and extended service intervals across generator sets, data center backup systems, and heavy-duty industrial machinery.
