OEM direct replacement • Precision cast iron • Precision-machined surfaces • High structural integrity • Corrosion-resistant finish
The AZ2220000101 is a transmission front housing designed for the main transmission of SINOTRUK Howo A7 and T7H series trucks, as well as other heavy-duty models equipped with 12JSD and 16JSD manual transmissions.
This housing forms the front section of the transmission case, encasing the input shaft, front bearings, and the front gear train. It provides precise alignment and structural support for these critical components. Its OEM-grade construction replicates the original housing’s dimensions, bolt hole pattern, and sealing interfaces, ensuring a perfect fit and seamless integration.
The front housing is manufactured from high-quality cast iron with a controlled casting process that ensures optimal grain structure, dimensional stability, and strength. The housing is then precision-machined to exacting tolerances on all critical surfaces, including the bearing bores, mating surfaces, and bolt hole locations.
The AZ2220000101 features precision-machined bearing bores that provide accurate support and alignment for the input shaft bearings, ensuring smooth rotation and proper gear meshing. The mating surfaces are finished to a high standard to ensure leak-free sealing when assembled with the transmission case and end cover.
The housing includes strategically placed ribs and reinforcing features that enhance structural rigidity and resist deformation under load. Its robust construction and precise geometry contribute to transmission stability, smooth shifting, and extended component service life.
Common symptoms of a failing front housing include oil leaks from the front of the transmission, excessive vibration, gear misalignment, and visible cracks or damage to the housing. Replacing a damaged housing with the AZ2220000101 restores proper structural support and alignment, protecting the transmission from costly damage.
Whether you’re performing a major transmission overhaul or replacing a damaged case, this housing offers the quality, precision, and durability that SINOTRUK Howo professionals demand.
The AZ2220000101 transmission front housing is specifically designed for SINOTRUK Howo A7 and T7H series trucks equipped with 12JSD and 16JSD manual transmissions.
This housing forms the front section of the transmission case, providing structural support and precise alignment for the input shaft, front bearings, and front gear train.
It serves as a direct replacement for the original factory housing and is compatible with all transmissions that use this specific housing configuration.
This front housing is essential for applications involving heavy loads, frequent shifting, and demanding operating conditions, such as long-haul transport, construction, and mining.
In these environments, the housing is subjected to extreme loads, vibration, and thermal cycling. The AZ2220000101 is engineered to withstand these harsh conditions, providing consistent structural support and transmission integrity.
When replacing a front housing, it is important to inspect the input shaft, bearings, and gear train for wear – these components often require replacement together. The AZ2220000101 is designed to work with the factory-spec mating components, ensuring proper alignment and clearance.
For fleets with multiple HOWO trucks equipped with 12JSD or 16JSD transmissions, this housing standardizes repairs, simplifying parts inventory and ensuring the correct component is available for scheduled maintenance or transmission overhauls. Always verify the transmission model and housing configuration on your truck to confirm compatibility, though the AZ2220000101 is the standard front housing for the majority of 12JSD and 16JSD transmission applications in A7 and T7H chassis.
Replacing the AZ2220000101 transmission front housing 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 front housing. Carefully remove the bolts securing the housing, taking note of their positions and any sealant used.
Clean the mating surfaces on the main case thoroughly, removing all old sealant, gasket material, and debris. Inspect the bearing bores and sealing surfaces for wear or damage.
Apply a thin bead of high-temperature sealant to the mating surface of the new AZ2220000101 housing. Position the housing and install the bolts, torqueing them to the manufacturer’s specified value (typically 40-60 Nm) in a crisscross pattern.
Reassemble 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 housing seal or gasket. The AZ2220000101 is built for long service life, but early detection of leaks or damage is key to preventing major transmission failure.
The AZ2220000101 transmission front housing is manufactured in an ISO 9001-certified facility using advanced casting, machining, and finishing processes.
The cast iron is sourced from certified mills and undergoes chemical analysis to confirm its composition and mechanical properties. Each housing is cast to near-net shape and then precision-machined to exacting tolerances.
Every housing undergoes a comprehensive series of quality checks, including dimensional verification of all critical features, bore inspection, and surface finish evaluation.
The housing is checked for casting defects, porosity, and structural integrity. Random samples from each batch are subjected to pressure testing and durability simulation to confirm long-term reliability.
We back the AZ2220000101 with a comprehensive warranty against material and workmanship defects. Our rigorous quality control ensures that every housing delivers the same fit, strength, and durability as the original factory part, giving you confidence in your transmission’s structural integrity.
