OEM WG9003320476/1 Aux Rear Countershaft Bearing for HOWO
The WG9003320476/1 auxiliary box countershaft rear bearing is a precision-engineered component designed specifically for HOWO heavy-duty trucks. This critical transmission component ensures optimal power transfer and durability in the demanding environments faced by HOWO commercial vehicles. Manufactured to meet stringent quality standards, it provides reliable support for the countershaft assembly while maintaining proper gear alignment under extreme loads and high-temperature conditions common in long-haul trucking operations.
Premium Transmission Performance
Optimized for HOWO truck transmissions, the WG9003320476/1 rear bearing significantly reduces friction and heat generation within the gearbox assembly. Its precision-ground surfaces and specialized heat treatment ensure consistent performance across varying temperature ranges, preventing premature wear even during extended operation periods. The component’s robust construction effectively handles torsional stresses during gear shifts and maintains critical tolerances after thousands of operational hours, reducing maintenance downtime for fleet operators.
Engineering Specifications
Crafted from high-grade bearing steel with advanced surface hardening, this countershaft rear bearing provides exceptional resistance to pitting and spalling. The integrated seal design prevents lubricant leakage while effectively excluding contaminants from the bearing raceways. Proper installation of the WG9003320476/1 bearing ensures precise shaft positioning, directly contributing to smoother gear engagement and reduced gear whine in HOWO transmission systems.
Durability Features
This bearing incorporates advanced cage designs that maintain ball separation at high rotational speeds, minimizing friction and heat build-up during highway driving. The micro-polished raceways create optimal lubricant film retention, providing continuous protection during cold starts and high-load situations. With its specialized material composition, the component withstands shock loads from rough road conditions and heavy payloads without deformation or surface degradation.
Compatibility Information
Designed as a direct replacement for original equipment, the WG9003320476/1 bearing installs without modifications in HOWO T7, A7, and ZZ series transmission systems. Its dimensional accuracy ensures perfect fitment with existing shafts and housings. The component meets or exceeds original performance specifications, providing an OEM-equivalent solution for transmission rebuilds and repairs.
Operational Benefits
Vehicles equipped with the auxiliary box countershaft rear bearing experience significantly reduced transmission vibration and noise levels. Its optimized internal clearance settings maintain proper preload throughout thermal expansion cycles, preserving bearing integrity during temperature fluctuations. This translates to improved fuel efficiency through reduced parasitic power loss and longer service intervals for HOWO operators.
Maintenance Advantages
The robust design of the WG9003320476/1 minimizes the need for premature replacement, with typical service life matching the OEM component’s lifespan. Its standardized dimensions enable straightforward installation using conventional bearing press tools, and the part includes visual indicators to ensure proper orientation during assembly. This reduces technician error and simplifies transmission service procedures.
Application Guidelines
Proper installation requires clean working conditions and appropriate lubricants compatible with HOWO transmission fluids. Technicians should follow factory torque specifications for mounting bolts to prevent distortion of bearing races. Periodic inspection during transmission service intervals is recommended to verify lubrication effectiveness and wear condition, though the bearing’s design typically provides maintenance-free operation between scheduled services.
Quality Assurance
Each WG9003320476/1 bearing undergoes dimensional verification and rotational testing before packaging. The component arrives pre-lubricated with factory-approved grease in sealed, contaminant-proof packaging to preserve its condition until installation. Manufacturer certifications guarantee material composition and hardening processes, providing assurance of component reliability in commercial vehicle applications.
Technical Support
Comprehensive installation documentation accompanies each WG9003320476/1 bearing, including detailed torque specifications and alignment procedures specific to HOWO transmission systems. Technical specialists are available to provide application support for complex installations or troubleshooting assistance. This OEM-equivalent component eliminates compatibility concerns and ensures seamless integration with existing HOWO transmission systems.
