Replacement Main Shaft Reverse Gear WG2210040040/1 for HOWO

The WG2210040040/1 main shaft reverse gear is a critical transmission component specifically engineered for HOWO commercial trucks. This precision-engineered part facilitates smooth gear shifting between forward and reverse motions, essential for maneuvering heavy vehicles in challenging conditions. Manufactured to exact OEM specifications, this replacement gear ensures compatibility and reliability for HOWO truck transmissions experiencing reverse gear issues.

Optimal Performance for HOWO Transmission Systems

Specially designed for HOWO heavy-duty trucks, the WG2210040040/1 reverse gear features hardened steel construction with precisely machined teeth profiles that maintain optimal meshing with synchronizer components. The helical cut design reduces gear whine and vibration during reverse engagement, while the surface treatment enhances wear resistance in high-torque applications. Truck operators will notice improved shift quality and reduced transmission chatter when replacing worn components with this authentic WG2210040040/1 gear assembly.

Enhanced Durability Features

This main shaft reverse gear incorporates several durability enhancements critical for commercial truck operations. The induction-hardened teeth surfaces provide superior resistance to pitting and spalling under heavy loads. Precision grinding after heat treatment ensures uniform tooth geometry for consistent load distribution across the entire gear face. The spline connection is engineered to withstand high torsional stresses during trailer reversing maneuvers, preventing premature wear at the shaft interface. By choosing the genuine WG2210040040/1 replacement part, fleet managers avoid the vibration issues and accelerated wear common with inferior aftermarket components.

Application-Specific Engineering

The WG2210040040/1 isn’t a universal reverse gear but a purpose-built solution for specific HOWO transmission configurations. Its dimensional specifications correspond exactly to factory blueprints for critical parameters including pitch diameter, pressure angle, and helix angle. This guarantees proper alignment with the counter shaft gear and precise synchronizer ring engagement. Compatibility extends to multiple HOWO truck models with synchronized manual transmissions, particularly those operating in construction, mining, and long-haul applications where reverse gear reliability is paramount. Each WG2210040040/1 undergoes rotational balance testing to prevent harmonic vibrations that can damage bearings over time.

Installation Advantages

When replacing the main shaft reverse gear WG2210040040/1, technicians benefit from several installation-friendly features. The precision-machined bore maintains tight tolerances with the main shaft, eliminating the need for shimming or custom fitting. The gear’s chamfered edges prevent damage to synchronizer rings during assembly, while the clearly marked installation direction indicators prevent reverse mounting errors. Compatible with standard gear pullers and presses, the WG2210040040/1 simplifies transmission overhaul procedures, reducing workshop downtime for HOWO trucks.

Preventative Maintenance Considerations

Proactively replacing the WG2210040040/1 main shaft reverse gear during scheduled transmission maintenance prevents costly secondary damage. Worn reverse gears typically manifest through difficult shifting, unusual grinding noises during reverse engagement, or complete inability to select reverse gear. Delaying replacement risks damaging the reverse idler gear, synchro assembly, and even the transmission case. With a typical service life of 500,000 km under normal conditions, incorporating the WG2210040040/1 into transmission overhaul kits ensures HOWO trucks maintain optimal shifting performance throughout their operational lifespan.

Engineering Specifications

The WG2210040040/1 reverse gear meets all original equipment material standards with its case-hardened 8620 alloy steel construction. Each gear features 26 precision-ground teeth with 25¡ã helix angle optimized for smooth engagement. The bore diameter maintains 0.002″ interference fit with the main shaft to prevent rotational slippage under high torque loads. As an OEM-specified component, the WG2210040040/1 guarantees dimensional consistency not just in tooth profile, but also in key parameters like root fillet radius and tooth tip clearance that affect noise generation and load capacity.

Performance Testing Validation

Each production batch of WG2210040040/1 gears undergoes rigorous performance validation exceeding industry standards. Endurance testing simulates 10,000 high-torque reverse engagements with full trailer loads. Surface durability tests verify the hardened teeth withstand contact pressures exceeding 200,000 psi without deformation. Rotational balance is maintained within 0.5 g-cm across the entire operational RPM range. These validation protocols ensure the WG2210040040/1 provides predictable performance and longevity in the most demanding HOWO truck applications.

Operational Cost Benefits

Selecting the genuine WG2210040040/1 reverse gear delivers tangible operational savings for HOWO fleet operators. Its extended service life reduces transmission overhaul frequency by 30-40% compared to aftermarket alternatives. The precision manufacturing reduces synchronizer ring wear, preserving shift quality and preventing secondary component failures. By maintaining proper gear meshing characteristics, the WG2210040040/1 prevents abnormal driveline vibrations that accelerate universal joint and bearing wear. These cumulative benefits make this OEM-specified gear the most cost-effective choice throughout the truck’s service life.

Compatibility Information

The WG2210040040/1 main shaft reverse gear is compatible with HOWO truck models equipped with HW19710 and HW19712 transmissions manufactured between 2015-2023. Always verify transmission serial number against OEM compatibility charts before installation. This gear interfaces with specific synchronizer assemblies including part numbers WG2210040038 and WG2210040039. Not compatible with earlier transmission versions that used tapered roller bearings. The WG2210040040/1 supersedes previous revision WG2210040040 with improved tooth root radius design.
