Product Overview – AZ22210040207 Reverse Gear

The AZ22210040207 is a reverse gear designed for use in SINOTRUK Howo transmissions, particularly the 12JSD and 16JSD series manual gearboxes found in A7 and T7H heavy-duty trucks. This gear is part of the reverse gear train and is responsible for enabling smooth, reliable backing operations. Its OEM-grade construction precisely matches the original gear’s dimensions, tooth profile, and material specifications, ensuring perfect fitment and consistent performance.

The reverse gear is manufactured from high-quality alloy steel with precision-cut gear teeth that are carefully profiled to ensure smooth engagement and quiet operation. The gear teeth are carburized or induction-hardened to achieve a wear-resistant surface while maintaining a tough, ductile core that can withstand shock loads. The gear is then precision-ground to achieve the required tooth profile and surface finish, minimizing friction and noise during operation.

The AZ22210040207 features a carefully calculated gear geometry that provides the correct gear ratio for reverse operations, allowing for smooth maneuvering in tight spaces and controlled backing under load. The gear is designed to mesh precisely with the reverse idler gear and the reverse drive gear, ensuring smooth power flow and minimizing the risk of gear clash or damage during engagement.

Common symptoms of a failing reverse gear include grinding noises when engaging reverse, difficulty shifting into reverse, popping out of reverse gear, and visible wear or chipping on the gear teeth. Replacing a worn reverse gear with the AZ22210040207 restores smooth, reliable reverse operation and protects the transmission from further damage.

Whether you’re performing a major transmission overhaul or repairing a reverse gear issue, the AZ22210040207 Reverse Gear offers the quality, precision, and durability that SINOTRUK Howo professionals demand.

Compatibility & Applications – AZ22210040207 Reverse Gear

The AZ22210040207 reverse gear is specifically designed for SINOTRUK Howo A7 and T7H series trucks equipped with 12JSD and 16JSD manual transmissions. This gear is used in the reverse gear train, working in conjunction with the reverse idler gear and the reverse drive gear. It serves as a direct replacement for the original factory reverse gear and is compatible with all transmissions that use this specific gear configuration.

This reverse gear is essential for applications involving frequent backing maneuvers, such as construction, mining, and heavy hauling. In these demanding environments, the reverse gear is subjected to high torque loads and shock forces. The AZ22210040207 is engineered to withstand these harsh conditions, providing reliable and consistent reverse operation.

When replacing a reverse gear, it is important to inspect the reverse idler gear, the reverse drive gear, and the shift fork for wear – these components often wear together. The AZ22210040207 is designed to work with the factory-spec mating parts, ensuring proper gear mesh and backlash. Replacing the reverse gear together with the idler gear and shift fork is recommended for optimal reverse operation.

For fleets with multiple HOWO trucks equipped with 12JSD or 16JSD transmissions, this reverse gear standardizes transmission repairs, simplifying parts inventory and ensuring the correct component is available for scheduled maintenance or transmission overhauls. Always verify the transmission model and gear set type on your truck to confirm compatibility, though the AZ22210040207 is the standard reverse gear for the majority of 12JSD and 16JSD transmission applications in A7 and T7H chassis.

Installation & Maintenance – AZ22210040207 Reverse Gear

Replacing the AZ22210040207 reverse gear is a complex procedure that requires advanced mechanical knowledge, specialized tools, and access to a transmission workbench. This work should only be performed by qualified transmission technicians or experienced heavy-duty mechanics. Begin by safely removing the transmission from the vehicle and mounting it on a suitable work stand.

Drain the transmission fluid and disassemble the transmission case to access the reverse gear train. Carefully remove the old reverse gear, noting the orientation and the position of any thrust washers or spacers. Inspect the gear teeth, the idler gear, and the shift fork for wear patterns – if the reverse gear shows excessive wear, replace it with the new unit.

Clean all internal components with a suitable solvent and inspect the mating gears for wear or damage. If any mating components show significant wear, replace them to ensure proper gear mesh and reverse gear longevity. Lubricate the new AZ22210040207 reverse gear with clean transmission fluid before installation.

Install the new reverse gear onto the shaft, ensuring correct orientation and alignment with the idler gear and the reverse drive gear. Secure the retaining rings and reinstall any thrust washers or spacers. Reassemble the transmission, torqueing all fasteners to the specified values. Refill with the recommended grade and quantity of transmission fluid.

For maintenance, regular transmission fluid changes at manufacturer-recommended intervals (typically 50,000-100,000 km) are essential to ensure the reverse gear and other components are properly lubricated. If you notice grinding noises or difficulty engaging reverse, inspect the reverse gear train promptly. The AZ22210040207 is built for long service life, but early detection of wear is key to preventing major transmission damage.

Pro Tip: When installing the new AZ22210040207 reverse gear, always inspect the reverse idler gear bushing and shaft for wear. Replace the shift fork and synchronizer components if they show signs of wear to ensure smooth and quiet reverse engagement.
