The Caterpillar 0R-8786 is a premium remanufactured diesel fuel injector purpose-built for the CAT 3412 series engine platform, with verified fitment for 3412, 3412B and 3412C engine variants across marine, industrial and power generation configurations. Validated as an OEM-equivalent replacement, it supports cross-reference matching with part numbers 4P9830 and 8N7005, and adheres to strict Caterpillar remanufacturing standards to deliver consistent fit and function for global diesel engine fleets.
Leveraging a precision mechanical injection design and high-strength alloy construction with industrial-grade sealing, the injector meters exact fuel volumes per engine load, atomizes fuel for optimized combustion, and reduces fuel consumption, black smoke and carbon deposit formation. Its corrosion-resistant, heavy-duty build supports continuous-duty operation in harsh environments, while extended service intervals support reduced maintenance frequency for operation-critical assets.
This injector is compatible with a broad range of heavy-duty equipment, including marine propulsion systems, mining machinery, generator sets, oil and gas equipment, construction machinery and stationary industrial pump drives. Backed by Caterpillar’s global service network for accessible parts and technical support across regions, it is a trusted solution for B2B engine maintenance, repair and fleet management programs.
