SINOTRUK HOWO Heavy Duty Truck Transmission End Small Cover Housing WG222221003


This Heavy Duty Truck Transmission End Small Cover Housing (Part No. WG222221003) is a precision-engineered sealing component designed specifically for SINOTRUK HOWO manual transmission gearboxes. Featuring a dual-lever rocker arm side configuration and a robust integrated O-ring sealing track, this housing addresses the chronic issues of lubricant leakage and internal gear contamination often experienced under grueling transport loads. It is widely applied in severe-duty fleet applications, including mining dump trucks, long-haul freight vehicles, and heavy construction transits, ultimately shielding vital synchronizer assemblies and extending the operational lifecycle of the entire powertrain.

Precision Oil Sealing: Engine-machined with a dedicated O-ring groove allocation, this housing delivers a flush, leak-proof barrier across the gearbox end interface. It blocks internal transmission oil migration and prevents fluid starvation, ensuring continuous, localized gear lubrication across high-stress fleet shifts.
Die-Cast Aluminum Integrity: Cast from structurally dense, low-porosity aluminum alloy, this structural component balances minimal weight with excellent tensile resilience. It withstands severe structural pressure and continuous torsional feedback from the gear selector shafts without suffering hairline casing fractures.

Harsh Terrain Defiance: Engineered with an anti-corrosion barrier coating, this end cover resists moisture oxidation, corrosive road salts, and high-density worksite dust infiltration. It operates reliably under intense thermal cycling, protecting vital sub-assemblies inside active heavy dumpers and mining haulers.

Exact OEM Specification: Manufactured to precise dimensional geometries, this component guarantees a direct-fit replacement for existing worn housings. Operators can execute direct replacements during routine driveline overhauls without requiring additional shimming or physical alterations, drastically minimizing fleet vehicle downtime.


Drivetrain Vibration Dampening: The rigid mounting footprint and integrated dual-lever arm stabilizer support eliminate loose play within the linkage selector base. By isolating powertrain harmonics, it dampens driveline vibration, eradicates annoying selector rattle, and restores seamless, secure gear engagement for operators.
