Product Details
Premium 419-0841 Internal Unit Injector Wiring Harness for Caterpillar C9 Engines
The 419-0841 Internal Wiring Harness Assembly is a critical electrical component specifically engineered for the Caterpillar (CAT) C9 and C-9 engine platforms. Located under the valve cover, this harness serves as the primary connection between the external ECM harness and the individual unit injectors. Our OEM New 419-0841 ensures precise voltage delivery to each injector, eliminating intermittent engine misfires, rough idling, and persistent injector circuit fault codes.
I. Engineered for the Internal “Hot Zone”
Operating submerged in hot engine oil with intense thermal cycling, the 4190841 harness is built to exceed the challenges of the internal engine environment:
- Oil-Resistant Insulation: Features high-grade fluoropolymer insulation that prevents the “spongy” degradation caused by long-term immersion in hot lubricants.
- Vibration-Proof Terminals: Injector connectors maintain high-pressure contact force to ensure the relentless vibration of a 336D excavator doesn’t cause signal dropouts.
- Heat-Stabilized Connectors: Manufactured with glass-filled nylon to resist becoming brittle, a common failure point in older or low-quality alternatives.
II. Vast Application Across the Caterpillar Fleet
The 419-0841 is a highly versatile part, essential for an expansive range of CAT heavy equipment:
| Excavators | Direct replacement for 330C, 330D, 336D, 336D2, and 340D2 L series. |
| Tractors & Loaders | Essential for D6R, D6T, and the heavy-duty 973D Track Loader. |
| Graders & Scrapers | Optimized for 140M/160M motor graders and 627G/637G wheel scrapers. |
| Power & Forestry | Supports C9 Generator Sets, Marine Engines, and Track Feller Bunchers (521B, 552). |
III. Technical Verification & 12-Month Warranty
