This listing describes a Rayfuel aftermarket product for a Denso common-rail injection system. It is not presented as a genuine John Deere or genuine Denso boxed component. Similar injector bodies may use different calibration or internal specifications, so appearance alone is not sufficient to establish compatibility.

Product Identification

• Primary part number: 095000-0590
• Writing variation: 0950000590
• John Deere references: RE543351 and RE545562
• Product type: Common rail diesel fuel injector assembly
• Injection system: Denso system
• Engine applications: Selected John Deere 4045 and 6068

The number 095000-0590 identifies the injector supplied in this listing. The form 0950000590 is the same number written without punctuation, not a separate component. RE543351 and RE545562 are the supplied John Deere cross-references. Check the complete suffix because other 095000-series injectors can look similar but may not interchange.

095000-0590 Denso diesel fuel injector application and fitment

This injector is listed for selected John Deere machines powered by 4045 4.5L and 6068 6.8L engines. Exact fitment can vary by machine model, engine serial number, production date, emissions configuration and part-number supersession. Engine family alone is useful for initial identification but cannot replace an exact parts-record check.

Compare 095000-0590, RE543351 and RE545562 with the markings on the removed injector or a reliable machine and engine-serial parts record. Also compare the terminal arrangement, high-pressure inlet, body profile, sealing surfaces and nozzle end shown in the gallery. If the removed part carries another number, confirm the interchange before ordering.

Injector Function and Performance

A common-rail injector meters high-pressure diesel fuel and delivers controlled injection events into the combustion chamber. Correct operation supports dependable starting, stable idle, balanced cylinder contribution and consistent response under load. Injector performance also depends on correct rail pressure, clean fuel, sound wiring, suitable compression and the condition of the complete injection system.

Common Signs This Injector May Need Replacing

• Hard starting or extended cranking
• Rough idle or uneven cylinder contribution
• Reduced power under working load
• Increased exhaust smoke
• Abnormal diesel combustion noise
• Excessive injector return flow
• Injector-related diagnostic fault codes

These symptoms do not prove injector failure. Low fuel pressure, contamination, wiring problems, restricted supply or engine mechanical faults may produce similar complaints. Professional diagnosis and suitable injector testing are recommended before replacement.

Installation and Coding

Installation should be completed by a qualified diesel technician using clean working practices. Protect high-pressure connections from contamination, inspect associated pipes and renew seals required by the correct service procedure. Depending on the equipment controller, injector compensation or calibration information may need to be checked or registered with compatible diagnostic equipment. Do not assume the same coding procedure applies to every John Deere application.

Before You Order

Please confirm OE number, engine model or old part photos before ordering. Verify 095000-0590, RE543351 or RE545562, then confirm the machine and engine serial specification. General manufacturer information is available through the John Deere website, while exact injector selection should follow the appropriate parts record. Use the Rayfuel contact page for number and photo comparison support.

The 095000-0590 Denso diesel fuel injector is an OE-number-matched aftermarket replacement for confirmed John Deere applications.
