Import 3126b Caterpillar Engine Solenoid 9900015-12v — Buy in wholesale FOB from Supplier in China

The 3126b Caterpillar Engine Solenoid 9900015-12V is an 12-volt electromagnetic actuator designed for Cat 3126B HEUI (Hydraulically Actuated Electronically Controlled Unit Injector) fuel injection systems. This solenoid controls injector valve timing by converting electrical signals from the engine control module into precise mechanical movement, with part number cross-reference to Cat C7-C9 injector solenoid applications. China-Lutong Parts Plant manufactures this component as part of its diesel fuel injection product line, which includes head rotors, common rail nozzles, control valves, and injector assemblies for multiple OEM platforms.

The solenoid coil operates at 12V DC with typical resistance values standard for HEUI injector applications, though buyers should confirm ohm specifications directly with the supplier. The valve body and plunger assembly use hardened steel construction to withstand the cyclic pressures of high-pressure oil activation in HEUI systems, where oil pressures can reach 20,000 psi during injection events. Sealing surfaces are typically lapped to micron-level tolerances to prevent internal leakage that would cause injector misfire or rough idle. China-Lutong also produces related components including common rail injector assemblies, delivery valves, and plunger elements, suggesting vertical integration in diesel injection component manufacturing.

This solenoid serves as a replacement part for Caterpillar 3126B engine rebuilds, C7 and C9 series engine overhauls, and aftermarket remanufacturing of HEUI injectors. Primary buyers include diesel injection repair shops, heavy equipment rebuilders, mining machinery maintenance departments, and aftermarket parts distributors serving the construction and agricultural sectors. The supplier lists contact channels including email and WhatsApp for technical consultation, though no formal MOQ, lead time, or warranty terms appear in the source data, so buyers must confirm commercial terms and compatibility documentation before placing orders.

China-Lutong Parts Plant operates from Dufeng Industrial Road in Hanjiang District, Putian, Fujian Province, China, with postal code 351111. The supplier holds an 'imported' tier designation and 'harbor' trust level on the platform, with a recorded response rate of 0.00 and zero average response hours, indicating no documented response history through the platform interface. The supplier's product portfolio extends well beyond this single solenoid to encompass a full range of diesel fuel injection components.

The company lists its main product categories as head rotors for VE, DPA, DPS, and DP200 pump types; common rail nozzles for Bosch, Denso, and Delphi series; control valves for Delphi 621C/622B, Bosch, and Denso systems; common rail injectors; Euro 2 nozzles in S/P/SD/PD/SN/PN types; plungers; delivery valves; and various reference parts including supply pumps, feed pumps, repair kits, cam disks, and specialized tools. The source description contains extensive keyword lists for search optimization but limited verifiable company history, financial data, or certification specifics. Buyers should independently verify ISO quality system registration, production capacity, and export compliance documentation before committing to volume orders.
