The Genuine SINOTRUK HOWO Gearbox Countershaft Shaft End Cover (WG2222000001) is a vital, yet often overlooked, structural element within the transmission system. As a crucial piece of sinotruk spare parts, this end cover performs a dual function: it provides a robust seal to prevent the catastrophic loss of lubricating oil and ensures the precise axial alignment of the countershaft. In a high-torque, twin-countershaft gearbox like those found in the HOWO series, maintaining this alignment is paramount to preventing premature wear on gears and bearings.

Installation Notes
Replacing the countershaft end cover requires careful attention to detail to ensure a leak-free seal and proper transmission function. This procedure is best handled by a trained technician familiar with heavy-duty truck transmissions.
1.Preparation and Safety: Park the vehicle securely and drain the transmission oil if the cover is located below the oil level. Clean the area around the cover thoroughly to prevent any dirt or debris from entering the gearbox cavity.
2.Removal: Carefully remove the mounting bolts securing the old end cover. Gently pry the old cover away from the housing, taking care not to scratch or damage the precision-machined sealing surface of the transmission case.
3.Surface Cleaning: Remove all traces of the old gasket and any sealant residue from both the transmission housing and the new WG2222000001 cover. The sealing surfaces must be perfectly clean and dry.
4.Installation: Apply a thin, even bead of high-quality plane seal glue or RTV sealant to the new gasket (if required by the manual) and position the gasket onto the housing. Place the new end cover over the countershaft end.
5.Torque Sequence: Install the mounting bolts and tighten them finger-tight. Then, using a torque wrench, tighten the bolts in a cross-pattern sequence to the manufacturer’s specified torque (typically between 41 Nm and 51 Nm). This ensures even compression of the gasket and prevents warping of the cover.
6.Final Check: Refill the transmission with the correct grade and amount of gear oil. Run the engine and allow the transmission to warm up, then check for any signs of oil leakage around the newly installed cover.
