OEM AZ2203210030 • Small cover housing assembly • Precision machined • Corrosion resistant • Direct OEM fit
This small cover housing assembly is a critical protective and mounting component on the chassis and driveline of SINOTRUK Howo trucks. It encloses the end of a gearbox or transmission housing, supports a small cover plate and keeps lubricant inside while blocking dust, mud and water.
The assembly is cast and machined to exact OEM dimensions. Bolt hole spacing, mating face flatness, seal seat diameter, cover thickness and port positions all match the factory specification, so it installs correctly and maintains a reliable seal.
Common signs that a small cover housing assembly needs replacement include oil weeping at the mating face, cracks in the casting, stripped or corroded bolt holes, a distorted cover flange, damaged seal seats and impact damage from road debris.
Fitting a new AZ2203210030 Small Cover Housing Assembly restores a reliable seal, protects internal parts and keeps the driveline clean. It is a durable repair that supports long-term transmission reliability and reduces leak-related downtime.
This small cover housing assembly is designed for SINOTRUK Howo trucks, with primary compatibility across the A7, T7H, HOWO 371 and HOWO 380 series. It is a direct OE replacement, so it mounts to the original transmission or gearbox housing and accepts the factory cover and sealing hardware without modification.
The assembly is essential in applications where reliable protection and sealing are critical, such as long-haul transport, construction, mining and municipal service. In these duties, it must resist vibration, heat, oil, dust, mud, water and temperature extremes.
When replacing the housing assembly, it is recommended to inspect the mating surface, gasket, bolts and internal components for wear or damage. This part is designed to work with the factory driveline for correct fit and reliable operation.
For fleets with multiple HOWO trucks, standardising on this housing assembly simplifies maintenance and ensures the correct part is available for scheduled service or emergency repairs.
Replacing this small cover housing assembly is a straightforward procedure that requires basic hand tools. This work should be performed by a qualified technician with the vehicle safely supported and the battery disconnected.
Clean the work area first so dirt cannot enter the housing. Remove the cover bolts, take off the cover and gasket, and unbolt the old housing. Inspect the mating surface and internal parts for wear, corrosion or damage.
Position the new housing on the transmission, align the bolt holes and install the bolts. Tighten them evenly to the OEM torque, fit a new gasket and cover, and refill the lubricant to the correct level.
Run the engine and check for leaks at the mating face and cover. During routine service, inspect the housing for cracks, oil weeping or loose bolts and replace it if any damage is found.
This small cover housing assembly is manufactured in an ISO 9001-certified facility using high-strength cast alloy and a corrosion-resistant coating. Incoming castings are checked for dimensions, material hardness and surface quality before machining begins.
Each housing is machined on precision equipment, then inspected for bolt hole positions, mating face flatness, seal seat diameter and cover fit. Every batch is dimensionally checked, and samples receive a pressure and fit test before packing.
Batch samples undergo salt spray, thermal cycling and vibration testing to confirm long-term reliability in heavy-duty truck use. These checks help ensure the housing performs in the tough conditions Howo trucks face every day.
This housing assembly is covered by a 12-month warranty against material and workmanship defects. Strict quality control means every unit matches the fit, function and durability of the original factory part.
This small cover housing assembly is a vital component for maintaining reliable sealing, protection and structural support on your Howo truck. A cracked or leaking housing can allow oil loss and dirt ingress, causing wear and damage to internal transmission parts.
