Product Details
Stamp 170-5187 (CAT legacy injector tag, 3304/3306/3406 pre-HEUI mechanical family) configures as a tappet-actuated fuel-metering lance for CAT 3304 / 3306B/C / 3406B 6-cyl in-frame mechanical diesels in off-highway trucks, graders, gensets, marine. It encases a poppet rod, tension spring, calibration pin, and a multi-port spray crown within a CAT-profile hex-column shell anchored by a bronze gasket. Firing pressure ~1900–2100 psi-class (shim/serial dependent), 6–7 hole array, 60° taper, carburized alloy steel. Not an electro-rail element, not a HEUI canister, not a bare jet element. Procurement tags: CAT 170-5187 / 1705187 / pairs with 4W-7019 nozzle / 7W-703x lineage / superseded in part by 0R-3536 reman.

Our Advantages
Tuned fuel circuit geometries deliver accurate flow regulation, drastically mitigating interfacial wear across broad crankshaft speed spectra while optimizing residual power preservation during yard standby and international freight logistics cycles. Every manufacturing batch undergoes full analytical verification at accredited laboratory facilities to verify calibrated feed pressure standards, rigid joint structural robustness, and homogeneous injection atomization patterns, sustaining prolonged operational endurance within fast-paced mass-production environments. The modular layout ensures full cross-compatibility with official OEM maintenance guidelines, allowing expedited component swaps without rotational realignment during routine service intervals. This substantially cuts equipment downtime and alleviates secondary operational expenditure loads. Shielded by a heavy-duty long-wearing outer enclosure, the unit provides consistent, low-monitor performance purpose-engineered for highway freight transport fleets and stationary auxiliary power generation systems.
FAQ
1.Jet element, solenoid rail cartridge, or tappet-actuated metering lance?
Tappet-actuated metering lance - poppet, spring, crown, pin in one column. No separate multi-port insert, no coil winding, no KDAL jacket, not 2645K011 cam-driven rod (Perkins thread clash), not 364-7040 electro-rail dispenser, not LJBB03202A flux-column, not CA0R3536 (CA0R3536 is 3408/3412 reman twin, 170-5187 is 3304/3306/3406 body).
2.170-5187 ex 3306B into 3406B head - straight swap or pressure verify?
Port bore and bronze gasket align across 3306/3406 decks (same CAT mechanical cup). But 3406B CPL often carries a stiffer shim pack (~150–200 psi higher); force-fit causes uneven cylinder smoking with zero ECU alert (fully mechanical). Bench crack-pressure before fleet-wide install; also check the 4W-7019 tip seat wear separately from the 170-5187 body.
