Details
The c-aterpillar 293-4072 fuel injector is a premium, OEM-compliant component engineered specifically for c-aterpillar C9 series diesel engines. Cross-referenced with part numbers 2934072, CA2934072, and 10R-7222, it serves as a core element of the engine’s fuel delivery system, utilizing advanced HEUI (Hydraulically Actuated Electronically Controlled Unit Injection) technology to deliver precise fuel metering and timing control. Manufactured to meet c-aterpillar’s original design standards and ISO 9001 quality certific-ations, this injector ensures seamless plug-and-play installation without modific-ations to the engine or fuel system. As a new aftermarket part, it is built to withstand the demanding conditions of construction, mining, and industrial applic-ations, delivering exceptional durability and performance. Key features include precision-machined multi-hole nozzles for superior fuel atomization, a heat-treated alloy steel body with corrosion-resistant coating, and strict 100% factory bench testing for electrical properties, pressure resistance, spray pattern consistency, and sealing integrity. This injector effectively resolves common engine issues such as misfires, power loss, and excessive fuel consumption, while optimizing combustion efficiency to reduce emissions and lower long-term operational costs. Backed by a 12-month quality warranty, flexible minimum order quantities (MOQ), and fast global delivery (3–7 working days), the 293-4072 is an ideal choice for global aftermarket and export customers seeking reliable replacements for C9-powered excavators, loaders, generators, and heavy machinery.

4. Installation & Maintenance Guidelines

表格

Item

Details

Installation

Disconnect battery negative pole and relieve fuel line pressure; clean injector interface thoroughly; replace O-rings and gaskets (disposable); torque to OEM specific-ation (26–31 N·m); apply lubricant to seals; verify part number compatibility; professional installation recommended

Maintenance Interval

Inspect injector performance every 6,000–10,000 operating hours; replace fuel filters every 200 hours/5,000 km; check electrical connections and coil resistance periodically; clean nozzles with ultrasonic cleaner if clogged to maintain atomization

Storage

Store in dry, clean, well-ventilated area (-15°C to 45°C); use VCI anti-rust bags and sealed packaging; avoid dust, moisture, extreme temperatures, and physical damage to nozzles

Troubleshooting

Diagnose engine misfires, power loss, or high consumption by checking nozzle clogging, fuel pressure leaks, and electrical connections; use KTS tools to read fault codes (e.g., 3–6 for high injector current); confirm C9 engine compatibility; follow c-aterpillar service manu
