Unique Core Competitive Advantages
- Triple reinforced plunger high-pressure boosting architecture, stable 1700bar+ rail pressure output, sufficient fuel supply to maintain steady digging torque under high altitude and heavy mining loads
- Built-in integrated precision SCV suction control valve, instant rail pressure adjustment, eliminate throttle lag during sudden excavation load switching
- Hardened precision barrel and plunger matching group with anti-impurity anti-corrosion coating, well adapted to high-impurity construction-site diesel fuel and extend overhaul intervals
- Complete hydraulic flow and ECU signal calibration on professional pump test bench before shipment, no ECU recoding or parameter adjustment required after direct installation
- Exact 1:1 OEM mounting flange, fuel pipe thread and multi-pin electrical connector, direct bolt-on replacement without modifying engine fuel pipeline or wiring harness
- Multi-layer reinforced high-temperature resistant sealing components on pump inlet, outlet and drive shaft, effectively prevent internal rail pressure loss and external fuel leakage under non-stop operation
- Pass wide-range temperature cyclic durability test (-30℃ ~ 125℃), stable consistent performance in northern cold highland construction sites and long-hour dusty open-pit mining environments
Packaging & Global Construction Machinery Logistics
- Heavy-duty reinforced export wooden case with full fixed foam liner, fully protect precision plunger internal components during long-distance sea freight cross-border transportation
- Overseas warehouse stock layout in Europe, Australia, Southeast Asia construction machinery core regions, local fast shipment within 24 hours for bulk equipment rental company orders
- Flexible shipping plans: DHL/FedEx/UPS fast door-to-door express for single retail pump, sea LCL consolidated container for repair shop wholesale bulk purchases
- 12-month comprehensive quality warranty under regular primary & secondary fuel filter replacement and clean qualified diesel fuel supply

Q1: Which engine and construction equipment is the 490-5709 fuel injector compatible with?
A: The 490-5709 fuel injector is a dedicated core part for Cater-pillar high-power industrial diesel engines, fully adapted to CAT C9.3 diesel engines. It is widely used in CAT 336E, 336F, 340F series crawler excavators, 966K/966M loaders, industrial generator sets and other heavy-duty construction equipment, with highly targeted matching performance.
Q2: Are there interchangeable part numbers for the 490-5709 injector?
A: The mainstream cross-reference OE numbers of this injector include 4905709, 20R-5079. All interchangeable models share the same injection parameters, installation size and fuel atomization standards, which can be replaced mutually without modifying engine parameters.
Q3: What abnormal equipment conditions mean the injector needs to be replaced?
A: When your CAT C9.3 engine has the following irreparable faults after routine maintenance, the injector needs to be replaced in time: severe cold start difficulty, obvious engine jitter at idle speed, insufficient power during heavy-load operation, excessive black smoke/blue smoke, rising fuel consumption, and engine misfire alarm code.
Q4: Does the 490-5709 injector need code matching after installation?
A: This high-precision injector is pre-calibrated before leaving the factory. For most standard CAT C9.3 equipment, it can be installed and used directly. Individual equipment with strict system recognition needs simple ECU code writing, and we provide free remote technical matching guidance.
Q5: What strict tests have been done on the 490-5709 injectors before delivery?
A: Every injector has passed professional multi-dimensional testing: high-pressure fuel injection sealing test, fuel injection volume precision calibration, atomization uniformity detection, high and low temperature cycle aging test and long-term load simulation test. All unqualified products are eliminated to ensure stable and consistent working performance.
Q6: What causes the 490-5709 injector to fail prematurely?
A: The main daily failure factors include using unqualified low-quality diesel, overdue replacement of fuel filter elements, long-term equipment idle and high-load overload operation, and fuel system impurity blockage. Standard use and regular maintenance can greatly extend the service life of the injector.
Q7: What are your procurement and delivery advantages for bulk orders?
A: We have sufficient spot inventory of 490-5709 injectors all year round, supporting sample test orders, small-batch trial sales and long-term exclusive distribution cooperation. All products adopt professional export shockproof, dust-proof and moisture-proof packaging, support global sea, air and land logistics, and can provide customized delivery plans according to customer needs.
Q8: What is the after-sales warranty policy for this injector?
A: We provide a standardized industry warranty period. For non-human damage and non-faulty installation performance problems occurring under normal use conditions, we support free after-sales maintenance and replacement services, with a complete after-sales tracking system to eliminate customer procurement risks.
