FAQ

Q: How do I verify that this injector (387-9436) fits my engine?
A: Please check the part number on your existing injector. It should match 387-9436, 387-9435, or 10R-2828. Additionally, confirm your engine model (e.g., Cat C9) and the equipment serial number. We recommend cross-referencing with your machine’s parts manual to ensure a perfect fit.

Q: What is the recommended installation procedure for this injector?
A: Installation should be performed by a qualified diesel mechanic. Key steps include: cleaning the injector bore, replacing copper washers and O-rings, lubricating the O-ring with clean engine oil, torquing the injector clamp to manufacturer specifications, and priming the fuel system to remove air. Always disconnect the battery before starting work.

Q: What maintenance is required after installing a new fuel injector?
A: After installation, run the engine and check for any fuel leaks around the injector base and fuel lines. It is also recommended to replace the engine’s fuel filter and water separator at the same time to ensure clean fuel reaches the new injector. Regularly use high-quality diesel fuel and change filters according to the manufacturer’s service schedule to maximize injector life.
