Product Details
Assembly 6212-11-3202 functions as a fully self-contained S-type mechanical injector (holder + needle + spring stack + integrated DLLA155S-class large-sac tip) engineered for Komatsu SA12V140-1 series V12 diesels in ultra-class wheel loaders. It seats into the cylinder head via the twin-stud MAN-style deck pattern adapted to Komatsu's 24 mm counterbore, retained by the matching 6212-11-3211 clamp yoke and copper washer. Bosch's internal designation rides inside the Komatsu envelope; pop pressure is CPL-locked (typically 220–235 bar class for SA12V140 NA/sub-turbo sub-models). Nitrided alloy steel body, 17 mm hex drive, M18×1.5 nozzle nut, 60° needle seat. Cross-reference lineage: Komatsu 6212-11-3202 / R6212-11-3202 (Reman) / Bosch S-type large-bore holder (0 430 233 xxx class). Not interchangeable with 131-series P-type tips, CAT 212-8470 GP injectors, or MAN 51.10100-x holders despite superficial S-type resemblance.

Our Advantages
Forged from thermally fortified high-grade metallic matrices, this ultra-precision fuel modulation unit sustains unbroken fluid conveyance and evenly distributed spray atomization through volatile pressure oscillations and repetitive thermal strain cycling. Each fully finished assembly undergoes intensive operational calibration to refine combustion proficiency, resolve sporadic cold-start performance irregularities, and deter carbon buildup inside cylinder bore chambers. Tuned internal flow path layouts elevate peak torque generation, curtail interval-based fuel consumption, and restrain noxious exhaust emissions. Engineered for uncomplicated fastener-free fitting and high-efficiency field maintenance, its rugged reinforced enclosure fits commercial haulage fleets, municipal excavation machinery and fixed power generation installations. Strict batch quality surveillance upholds unified manufacturing standards for all outbound export consignments, with professional procurement backing delivered via officially certified regional supply agents.
FAQ
1.Is 6212-11-3202 the nozzle tip or the whole injector?
Whole injector. Like CAT 212-8470 (but S-type, not GP), it bundles holder body, needle, spring, and large-sac S-tip in one screw-in unit. Ordering "6212-11-3202" gets the complete cartridge for the SA12V140 head-no separate DLLA tip, no KDAL-style holder to buy. The most common misorder is treating it like a Bosch 0 432 131 xxx P-tip and trying to screw it into a KDAL59P2.
2.Can 6212-11-3202 from a WA900-1L fit an SA12V140-1A without changes?
Deck pocket and twin-stud pitch match across WA800-2L / WA900-1L / SA12V140-1A/E/S, so mechanically yes. But Komatsu subtiered pop pressure by engine suffix (1A vs 1E vs 1S) via shim stack, and the Reman R6212-11-3202 may carry a revised calibration versus a 1990s original. Same threads, possibly 10–15 bar crack-pressure difference-bench-verify before fleet swap, don't trust the laser alone.
