WG2222100030 Aluminum Output Shaft Rear End Cover (Retarder)

Tailor-made for Sinotruk gearboxes equipped with hydraulic retarders, this part serves as a key sealing and supporting component at the rear end of the output shaft. It integrates the functions of bearing positioning, cavity sealing and adaptive mounting for the retarder.
Forged and processed from premium aluminum material, it features a dense structure and strong pressure-bearing capacity, perfectly adapting to high-load working conditions such as long-distance heavy haulage and downhill driving in mountainous areas.
Complying with original factory standard specifications and precise mounting hole positions, it can directly replace original vehicle parts without damage or modification.
It not only blocks external impurities from entering the gearbox housing, but also achieves long-term sealing together with the oil seal. Meanwhile, it assists the retarder in heat dissipation and temperature reduction, stabilizes the transmission operating condition, and prolongs the overall service life of both the gearbox and the retarder.

This dedicated aluminum output shaft rear end cover for retarders is integrally die-cast from high-strength aluminum alloy, featuring lightweight design, high rigidity and excellent deformation resistance.
Precision CNC finishing ensures accurate dimensions of mounting holes and spigots, enabling a perfect fit with retarders and gearboxes.
The flat and smooth end face delivers outstanding sealing performance, effectively preventing oil seepage and dust ingress while protecting internal bearings and transmission components.
Aluminum alloy boasts superior thermal conductivity and heat dissipation, quickly releasing heat generated by retarder operation and reducing high-temperature wear. With great corrosion and aging resistance, it is suitable for Sinotruk heavy-duty models. It can be installed at the original vehicle position with high durability and low failure rate.
