Product Details
Designation 1705187 (CAT 170-5187 nozzle group) operates as a cam-follower fuel-dosing javelin for CAT 3304/3306 mechanical blocks and C7–C18 heavy-duty powerplants in hydraulic excavators, crawler tractors, wheeled loaders, and standby generator sets. It secures a lift-valve, pressure-wound helix, positioning dowel, and a multi-aperture vaporizing head within a Caterpillar-spec polygonal housing sealed by a bronze crush washer. Combustion threshold derives from the host-lance shim arrangement (~1900 psi tier on 3304/3306 mech, elevated on C7/C9 CR crossbreeds), surface-hardened ferrous alloy, 60° chamfer. Neither a voltage-actuated rail device nor a hydraulically piloted capsule nor a solitary pencil emitter. Procurement aliases: CAT 1705187 / 170-5187 / 0R-1740 reman mate / 8N7005 (slim-tip context) / CA1705187.

Our Advantages
Upgraded fuel delivery architectures facilitate precise volumetric regulation, significantly mitigating surface degradation at contact interfaces across broad operational speed ranges and retaining surplus energy reserves during port idle standby and transoceanic goods transportation. Every production batch undergoes thorough performance validation at accredited testing hubs to verify calibrated pressure benchmarks, consistent structural robustness and homogeneous injection profiles, securing prolonged operational endurance within high-volume manufacturing workflows. The versatile build delivers complete component interchangeability in compliance with OEM maintenance specifications, allowing expedited fitting procedures without positional recalibration during periodic service intervals. This design efficiently curtails equipment downtime and relieves subsequent operational financial burdens. Protected by a heavy-duty long-lifespan outer housing, the module delivers stable, low-monitoring performance purpose-engineered for highway freight fleets and stationary emergency power assemblies.
FAQ
1.Standalone spray piece, current-driven rail artifact, or pushrod-governed dispensing spear?
Pushrod-governed dispensing spear - tappet, coil, crown, peg in one casing. No detached multi-port insert, no electromagnet winding, no KDAL jacket, not 8N7005 pencil barrel (1705187 is the fuller assembly 8N7005 sometimes nests in), not 364-7040 flux-column, not LJBB03202A electro-dispenser.
2. 1705187 ex 3306 into C7 head - straight seat or code audit?
Passage bore and copper ring align only across 3304/3306 mech decks; C7/C9 use a different cup class and (on CR hybrids) an electro-rail body - 1705187 mech spear won't physically latch into a C7 CR head. For 3304→3306 mech swap: same cup, but 3306B often hides stiffer shim pad (~150 psi up); force-fit yields asymmetrical cylinder haze, zero ECU alert. Bench crack-pressure before fleet install.
