Overview of X3000 Door Assembly Components: OEM Part Number Cross-Reference and Replacement Guide

    The Shaanxi Automobile (Shaanxi Auto) X3000 heavy-duty truck is widely recognized for its robust chassis design, high reliability, and modular cabin architecture. Among its service-critical subsystems, the door assembly plays a pivotal role in occupant safety, cab sealing integrity, acoustic performance, and operational ergonomics. This article provides a technical overview of the core door-related components applicable to standard X3000 cab configurations—specifically focusing on the 16 key OEM part numbers ranging from DZ14251330031 to DZ14251330156. All listed parts are genuine Shaanxi Auto factory-specified components and conform to the latest production revisions as of Q3 2026.

Core OEM Part Numbers and Functional Breakdown

    The following components constitute the primary structural and functional modules of the X3000 driver and passenger side doors:

    • DZ14251330031: Electric power window regulator assembly (left-hand drive configuration), integrated with anti-pinch logic and CAN bus-compatible control module. Rated for ≥50,000 actuation cycles under ISO 16750-2 vibration conditions.

    • DZ14251330061: Door inner panel mounting bracket sub-assembly, fabricated from cold-rolled steel ST14 with zinc-coated fastener interfaces. Designed to interface precisely with both the outer skin and inner trim carrier.

    • X3000车门内护板 (OEM equivalents include DZ14251330089, DZ14251330112): Multi-layer composite inner door trim panel incorporating polypropylene substrate, non-woven backing, and soft-touch PVC surface finish. Includes integrated map pocket, armrest reinforcement ribs, and pre-drilled speaker cutouts.

    • X3000玻璃升降器 (DZ14251330031, DZ14251330045, DZ14251330077): Three variants differentiated by motor torque rating and gear ratio—optimized respectively for standard, extended cab, and sleeper cab applications. All units feature IP54-rated enclosures and meet GB/T 2423.17 salt spray resistance requirements (96 h).

    • Additional critical items within the sequence include waterproof membrane (DZ14251330105), decorative bezel cover (DZ14251330132), speaker grille assembly (DZ14251330148), and upper hinge reinforcement plate (DZ14251330156). Each component undergoes dimensional validation per Shaanxi Auto’s internal GD&T specification SAE-X3000-DOOR-002.

Replacement Protocol and Technical Precautions

    When replacing any X3000车门附件, adherence to the following procedures is mandatory to ensure long-term system functionality and warranty compliance:

    1. Prior to disassembly, disconnect the vehicle’s 24 V DC main battery terminal and wait ≥60 seconds to deplete capacitor charge in the body control module (BCM). Failure to do so may trigger unintended airbag deployment or BCM fault codes.

    2. Use only Shaanxi Auto–approved torque specifications: M5 fasteners — 4.5 ± 0.3 N·m; M6 fasteners — 7.0 ± 0.5 N·m; hinge-to-cab bolts — 25 ± 2 N·m. Overtightening compromises thread integrity and thermal expansion tolerance.

    3. After installing the electric window regulator (e.g., DZ14251330031), perform full initialization via diagnostic tool (Shaanxi Auto SDT Pro v4.2+). This recalibrates end-stop positions and resets pinch detection thresholds.

    4. Inspect all sealing gaskets—including those integrated into DZ14251330105 (waterproof membrane)—for micro-cracks or compression set. Replace if visual inspection reveals loss of elasticity or adhesion integrity.

Accident-Related Component Declaration Requirements

    For insurance claims or warranty processing involving collision-damaged doors, Shaanxi Auto mandates submission of the following documentation alongside the original invoice:

    • High-resolution photographs showing part number stamps on each replaced item (e.g., DZ14251330061, DZ14251330148);

    • A signed technician verification form confirming no unauthorized modifications were made to wiring harness routing or mechanical linkages;

    • Diagnostic log printout verifying absence of stored BCM or gateway module faults prior to repair initiation;

    • For replacements involving DZ14251330031 or related glass lift mechanisms: calibration report generated by SDT Pro post-installation.

    Non-compliant submissions may result in claim rejection or delayed processing beyond the standard 15-business-day adjudication window.
