Fitment & Compatibility

Applicable Vehicle Models: SHACMAN heavy-duty trucks (double-check your truck's model and transmission first- saves fit issues later)

Compatible Transmission Models: Works with SHACMAN gearboxes, including Fast 12-speed and 16-speed units (paired with heavy-duty engines)

OE/OEM Reference Number: DZ90149320000 (exact match for SHACMAN's original part- no mods needed)

Interchangeability: Direct replacement for SHACMAN's stock driving gear. Won't fit other brands unless you rebuild the gearbox

VIN Matching Service: Send us your truck's VIN, and we'll confirm fitment in minutes- no guesswork

Technical Specifications

Material: 20CrNiMo alloy steel- tough, wear-resistant, built for heavy use

Dimensions: Made for SHACMAN transmission assemblies (ask for size drawings if needed)

Weight: 12.8 kg

Torque Capacity: Handles up to 4800 N·m without shearing or bending

Working Temperature Range: -40°C to 180°C- works in freezing cold and scorching heat

Surface Hardness: HRC 58–63 (hard enough to resist wear, not brittle enough to crack)

Key Tolerance: Gear tooth profile ±0.015 mm (smooth meshing, no grinding or power loss)

Material Grade & Source: 20CrNiMo alloy steel from top mills- premium, high-tensile. Material certificates available on request

Key Processes:

Precision forging: Shapes steel into gear form, boosting internal strength (tougher than cast parts)

Carburizing + quenching + tempering: Hardens teeth to prevent wear, keeps core flexible for heavy loads

Precision CNC hobbing: Cuts teeth to exact specs- smooth meshing, no rough shifts

Shot peening: Reduces surface stress, improves fatigue resistance for long hauls

Anti-rust coating: Prevents corrosion in muddy/dusty job sites

Production Capacity: Our factory has automated forging lines, CNC hobbing machines, and heat treatment shops. Handles bulk orders and custom jobs with ease

Quality Grade: OEM quality- meets all SHACMAN original part standards. No shortcuts

Inspection Items:

Gear tooth profile check: Perfect fit with companion gears

Hardness test: Verifies HRC 58–63 on teeth (tests every unit)

Torque load test: 4800 N·m to check for shearing/bending

Fatigue test: Thousands of load cycles for long-term reliability

Dynamic balance test: Prevents vibration and noise during use

Quality System Certification: IATF16949, ISO9001- strict quality control at every step

Batch Traceability: Unique serial number per batch- traceable to steel source, production date, and inspection records. Total transparency

Average Service Life: Over 500,000 km or 7 years (normal use)- 1.5x longer than cheap aftermarket gears (300,000 km max)

Performance Advantages: 40% more wear-resistant than standard steel; precise teeth reduce power loss; shot peening boosts long-haul durability

Heavy-Duty Performance: Thrives in tough conditions- steep hills, mining roads, construction stop-and-go. No wear, no deformation, no power loss

Common Issues with Cheap Gears: Fast tooth wear (grinding, power loss); brittle cores (cracks under load); poor tolerance (misalignment, transmission damage)

Our Improvements: 20CrNiMo steel + heat treatment (tough teeth); shot peening (no fatigue failure); precision machining (perfect alignment)

Cost Savings: Lasts 1.5x longer- cuts replacement frequency, avoids costly transmission repairs and downtime. Big win for fleets

Packaging Options: Neutral cartons (small orders); custom branded boxes (bulk); wooden boxes (sea shipping- shockproof, moisture-proof)

Anti-Rust & Shock Treatment: Anti-rust oil, plastic wrap, and foam padding- no scratches, rust, or damage during transit

Labeling: Stamped with part number, batch number, production date, and weight. Barcode for easy inventory

Stock Status: Year-round stock (top seller)- order today, ship tomorrow

Replenishment Cycle: 7–10 days for bulk orders if stock runs low

Minimum Order Quantity (MOQ): 1 piece for samples; wholesale MOQ negotiable (better prices for large orders)

Technical Matching Support: Send truck model/transmission/VIN- confirm fitment in minutes

Installation Guidance: Free drawings and video tutorials. Help available for installation questions (no charge)

Warranty Policy: 12-month warranty. Free replacement for quality-related failures (not user error)- no hassle

Custom Processing: Make gears from your drawings/samples- custom material, size, tooth profile

Small Batch Prototyping: Sample orders (min. 5 pieces) for new product testing

Customizable Items: Material grade, gear tooth profile, surface treatment (anti-rust/galvanizing), hardness level

Central Asia Market: Used on SHACMAN mining trucks in Kazakhstan- handles heavy loads/rough terrain with zero failures. Local fleets report 60% fewer transmission repairs

African Market: Fits SHACMAN long-haul trucks in Nigeria- performs in high heat/dust, no wear or power loss

Typical Use Scenarios: Mining dump trucks, construction haulers, long-haul freight rigs, heavy-load tankers (all SHACMAN heavy-duty models)

1.Can you match parts using my truck's VIN?

Yes. Send your VIN, and we'll confirm fitment within 24 hours.

2.What's the difference between your OEM gear and cheap aftermarket ones?

Ours is 20CrNiMo steel with proper heat treatment/machining- lasts 1.5x longer. Cheap gears use low-grade steel, wear fast, and damage transmissions.

3.How do I know if this fits my truck?

Check if it's a SHACMAN heavy-duty model. Unsure? Send model/transmission/VIN- we'll confirm for free.

4.What payment methods do you accept?

T/T, L/C, Western Union, VTB.

5.Can I get a sample?

Yes. Sample orders welcome- sample fee refunded on bulk orders.
