The WG2222020001 input shaft end cover is a vital component for maintaining transmission cleanliness and bearing integrity. A worn, damaged, or missing cover can allow contaminants to enter the transmission, leading to premature bearing failure, gear damage, and costly repairs.
This genuine OEM cover restores proper sealing and protection, ensuring your HOWO truck’s transmission operates reliably and efficiently.
OEM direct replacement • High-quality cast aluminum • Precision-machined sealing surfaces • Corrosion-resistant finish • Reliable bearing protection
The WG2222020001 is an input shaft end cover designed for the front of the transmission in SINOTRUK Howo A7, T7H, and other heavy-duty truck models. This cover mounts to the front face of the transmission housing, encapsulating the input shaft bearing and providing a sealed, protected environment for critical rotating components.
Its OEM-grade construction replicates the original cover’s dimensions, bolt hole pattern, and sealing interface, ensuring a perfect fit and seamless integration with the transmission housing.
The cover is manufactured from high-quality cast aluminum alloy, providing excellent strength-to-weight ratio, corrosion resistance, and thermal conductivity. The casting is precision-machined to achieve exacting tolerances on all sealing surfaces, bolt holes, and locating features.
The WG2222020001 features a precision-machined inner bore that accepts a shaft seal, preventing oil leakage and contamination ingress. The cover also includes strategically placed ribs and reinforcing features that enhance structural rigidity and resist deformation under load.
Its robust construction and exact fit contribute to reliable sealing, bearing support, and extended transmission life.
Common symptoms of a failing input shaft end cover include visible oil leaks from the front of the transmission, contamination of the input shaft bearing area, and premature bearing wear or failure.
Replacing a damaged cover with the WG2222020001 restores proper sealing and protection, safeguarding the transmission from costly damage. Whether you’re performing a transmission overhaul or addressing an oil leak, this cover offers the quality, precision, and durability that SINOTRUK Howo professionals demand.
The WG2222020001 input shaft end cover is specifically designed for SINOTRUK Howo A7 and T7H series trucks equipped with 12JSD and 16JSD manual transmissions.
This cover is used at the front end of the transmission, sealing the input shaft bearing and providing a protected environment for the clutch release mechanism and input shaft components.
It serves as a direct replacement for the original factory cover and is compatible with all transmissions that use this specific cover configuration.
This cover is essential for applications involving frequent clutch engagement, heavy loads, and demanding operating conditions, such as long-haul transport, construction, and mining. In these environments, the cover is subjected to vibration, thermal cycling, and potential impact from debris.
The WG2222020001 is engineered to withstand these conditions, providing consistent sealing and bearing protection. When replacing a cover, it is important to install a new shaft seal and inspect the input shaft bearing for wear – these components often require replacement together.
For fleets with multiple HOWO trucks equipped with 12JSD or 16JSD transmissions, this cover standardizes repairs, simplifying parts inventory and ensuring the correct component is available for scheduled maintenance or transmission overhauls. Always verify the transmission model and front cover configuration on your truck to confirm compatibility, though the WG2222020001 is the standard input shaft end cover for the majority of 12JSD and 16JSD transmission applications in A7 and T7H chassis.
Replacing the WG2222020001 input shaft end cover is a moderately complex procedure that requires mechanical skills and proper tools. This work should be performed by a qualified transmission technician or experienced heavy-duty mechanic.
Begin by safely removing the transmission from the vehicle and mounting it on a suitable work stand. Drain the transmission fluid and remove the clutch release mechanism to access the front cover.
Carefully remove the bolts securing the old cover, taking note of their positions and any sealant or gasket material used. Gently pry the cover off, being careful not to damage the sealing surface on the transmission housing.
Clean the mounting surface on the transmission housing thoroughly, removing all old sealant, gasket material, and debris. Inspect the input shaft bearing for wear or damage and replace if necessary. Install a new shaft seal in the cover bore, ensuring it is properly seated.
Apply a thin bead of high-temperature gasket sealant to the mounting surface of the new WG2222020001 cover. Position the cover and install the bolts, torqueing them to the manufacturer’s specified value (typically 25-35 Nm) in a crisscross pattern.
Reassemble the clutch release mechanism and the transmission, torqueing all fasteners to the specified values. Refill with the recommended grade and quantity of transmission fluid.
For maintenance, regularly inspect the front of the transmission for oil leaks, which may indicate a failing cover seal. The WG2222020001 is built for long service life, but early detection of leaks is key to preventing major transmission damage.
The WG2222020001 input shaft end cover is manufactured in an ISO 9001-certified facility using advanced casting, machining, and finishing processes.
The cast aluminum alloy is sourced from certified mills and undergoes chemical analysis to confirm its composition and mechanical properties. Each cover is cast to near-net shape and then precision-machined to exacting tolerances.
Every cover undergoes a comprehensive series of quality checks, including dimensional verification of all critical sealing surfaces, bolt hole positions, and overall geometry.
The sealing surfaces are inspected for surface finish and flatness, and the cover is checked for porosity and casting defects. Random samples from each batch are subjected to pressure testing and durability simulation to confirm long-term reliability.
We back the WG2222020001 with a comprehensive warranty against material and workmanship defects. Our rigorous quality control ensures that every cover delivers the same fit, sealing, and durability as the original factory part, giving you confidence in your transmission’s front-end protection.
