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.
