Product Details
Cartridge 236-1674 is a sealed mechanical injector assembly suited for CAT 3054C, C4.3, C4.4 as well as Perkins 1104C-E44T powertrains, widely deployed on 416E/420D/428D backhoe loaders, 914G compact wheel loaders and C4.4 generator sets. This unit combines the needle valve, compression spring, adjusting component and DLLA-type multi-hole nozzle tip within an M14 threaded housing, secured with a copper sealing washer. The popping pressure ranges approximately from 190 to 200 bar, tuneable via shim stack configuration. It features a 4-hole nozzle with roughly 0.25 mm orifices and a 150° spray angle. The nitrided injector body comes with 17 mm wrench flats and adopts a 60° sealing seat. Cross-reference part numbers: CAT 236-1674 / 266-6830 / 20R-0476, Perkins 2645K011.

Our Advantages
Sophisticatedly structured internal flow pathways enable delicate hydraulic calibration, maintaining stable crank-end torque amid recurrent load fluctuations and boosting overall fuel conversion efficiency during depot idling and overseas freight delivery. Each finished product undergoes independent quality inspection on accredited diagnostic benches to confirm standard actuation thresholds, long-term sealing retention and homogeneous spray uniformity, preserving consistent manufacturing quality across mass production runs. Fully interchangeable and strictly compliant with OEM fitting specifications, the unit installs flawlessly without on-site rework during routine maintenance cycles, substantially cutting equipment idle time and indirect operational overheads. Reinforced with an ultra-tough outer housing, it delivers steadfast, low-maintenance performance perfectly optimized for cross-border heavy-duty haulage vehicles and stationary emergency power systems.
FAQ
1.Tip or whole injector like 2645K014?
Whole mechanical injector - needle, spring, tip, adjuster in one body. No separate DLLA tip or holder. Same family tier as 2645K014 but 236-1674 runs ~190 bar class (2645K014 ~180 bar); casings not swapped blind.
2.Will 236-1674 from 3054C fit C3.3 genset without changes?
Thread/cup match 3054C and C3.3 heads. But C3.3 often uses 266-6830 sub with 5 bar different shim. Bench pop before fleet swap; same threads, don't trust etch.
