WG2203020177 Input Shaft End Cover

WG2203020177 is a dedicated input shaft end cover for heavy-duty truck HW series transmissions. Mounted on the front end of the transmission front housing, it integrates sealing, limiting and oil return functions, protecting the input shaft bearing and preventing lubricant leakage.

Made of wear-resistant and corrosion-resistant material, it meets OE machining precision and fits closely with oil seals and bearings.

It is compatible with mainstream heavy-duty truck models such as Howo and Sitrak, enabling direct replacement of original parts without modification.

Suited for complex road conditions including long-distance freight and construction site heavy-load operation, it serves as a core sealing component for transmission repair and maintenance.

WG220302017 input shaft end cover is precision cast from high-strength cast iron. After aging treatment, it has a compact structure, high rigidity, and resists deformation and cracking.

The mating surface and oil seal seat are precisely machined for excellent sealing and oil leakage prevention, effectively blocking dust and impurities.

Made to OE standard dimensions with accurate mounting holes, it offers great interchangeability and easy assembly.

Designed with an internal oil return groove, it ensures smooth lubrication circulation and low temperature rise.

It adapts to high-load working conditions at the front end of heavy-duty truck transmissions. With compression resistance, shock resistance and durable reliability, it protects the input shaft and bearings and extends the service life of the transmission.
