235-5261 6 Pcs Fuel Injector — Cat 325D

This is a set of six fuel injectors designed for precise fuel delivery into the combustion chamber of CAT C7 and C9 engines. Manufactured to meet stringent OEM standards, these injectors ensure optimal atomization and spray patterns, unlike worn injectors that can cause uneven fuel distribution. Operators may notice rough idling, a loss of engine power, or increased exhaust smoke when injectors begin to fail.

Installation & Application Notes

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

Initial signs of failing fuel injectors include a noticeable drop in engine performance and increased fuel consumption. If ignored, the issue can lead to rough idling, misfires, and excessive black smoke from the exhaust. Continued operation with faulty injectors risks uneven cylinder loading and potential damage to other engine components.

Installation Tip

Ensure the injector seats in the cylinder head are meticulously cleaned and free of any carbon buildup before installation. Avoid overtightening the injector hold-down bolts, as this can distort the injector body or damage the cylinder head threads.

Service Note

When replacing fuel injectors, it is advisable to inspect the fuel filter and fuel lines for any contamination or blockages.
