Product Details
Apparatus 105118-7371 functions as a consolidated single-spring S-type mechanical injector (ZEXEL 105118 family, KBL2.4-S / KBAL-S lineage) tailored for Fuji-Heavy industrial diesels and selected Mitsubishi 4D/6D non-highway derivatives. It encloses the needle valve, NP-DLLA-class S-type tip, sole bias spring, and adjuster screw within one M22-class threaded shell seated by copper annulus into the head cup. Crack pressure typically 17.7–18.1 MPa (180–185 bar) first-stage, with optional two-stage pre-lift variant at 23.1 MPa secondary per ZEXEL calibration sheets. Guide bore Ø5.00 mm, seat land 0.75 mm, 60° cone, 17 mm spanner flat. Cross-reference: ZEXEL 105118-7371 / Bosch-legacy 9 430 613 xxx / OE 2726320100-class.

Our Advantages
Tuned internal flow passages achieve swift fuel pressure adjustment, sustaining stable power output over an extensive working spectrum and curbing fuel consumption under light-load idle conditions and constant-speed cruising. Each finished component is subject to separate functional validation on certified test benches to inspect opening pressure, sealing durability and atomization properties, ensuring uniform quality among all production lots. Manufactured as a direct replacement part compliant with OEM installation standards, it can be fitted without field modifications during maintenance and effectively cuts equipment downtime. The strengthened structure facilitates long-lasting reliable operation for commercial transport vehicles and stationary standby diesel generator sets.
FAQ
1.Is 105118-7371 geometrically interchangeable with the ZEXEL 105118-8302 used on Isuzu 4JH1TC?
Negative. 8302 belongs to the ND-P 4JH1 turbo sub-line (Ø5.00 mm guide, 120–135 bar single-stage, 145° 4-hole 0.22 mm); 7371 sits in the KBL2.4-S S-type industrial sub-line (same Ø5.00 mm guide but NP-DLLA S-cone 150–155°, 180–185 bar first-stage with optional pre-lift). The nozzle nut thread pitch is identical (M20×1.0 class), yet the spring cup depth differs by 1.4 mm and the tip seat is S-cone not P-cone-swapping tips across bodies galls the needle at 200 hr. Same ZEXEL 105118 prefix, disjoint subsystems.
2.At 6000 hr on a Fuji-Heavy application, does 105118-7371 degrade guide-first (like Bosch 191-series 1345) or seat-ridge-first (like Bosch 131-series)?
KBL2.4-S exhibits a seat-ridge-dominant signature with concurrent micro-ovalization: the 0.75 mm seat land forms ridge ~6200 hr (crack drift −15 bar), while the Ø5.00 mm guide ovals to 0.004 mm only by 6800 hr. Thus it mirrors Bosch 131-series timing (seat-first by ~600 hr margin) but the guide tolerance is tighter than 131-series due to shorter 180-bar pulse. Diagnose via crack-pressure drop + low-speed return flow; a 7371 with 12 bar drift and clean return is pure seat leak-do not ream the guide.
