SINOTRUK HOWO Transmission / PTO System Parts HW19710 PTO Shaft Hole Cover Plate Set WG2229100047 WG2229100048

The SINOTRUK HOWO WG2229100047 PTO Shaft Hole Cover Plate and WG2229100048 Cover Plate Gasket are matching components used at the reserved Power Take-Off interface of heavy-duty truck transmissions. The cover plate closes the PTO mounting opening when an auxiliary PTO unit is not installed, while the gasket is positioned between the plate and transmission housing to create the required sealing interface. In the HW19710/HW19710T transmission, these components are associated with the range-gear/sub-gearbox assembly and work together with the corresponding fastening hardware to maintain a closed and properly sealed transmission housing. During vehicle operation, the cover plate remains fixed to the gearbox housing while the gasket helps accommodate the contact surface between the plate and housing, reducing the possibility of lubricant escaping through the unused PTO opening. If the original gasket has become compressed, brittle, or damaged, or if the cover plate has been deformed during gearbox maintenance, the sealing performance of this area may be affected. For replacement, buyers should confirm the transmission model, original part numbers, and mounting arrangement before ordering. When replacing the gasket, the mating surfaces should be cleaned and checked for damage so that the new gasket can sit evenly between the cover plate and transmission housing.
