Relevant knowledge

1. The function of Sinotruk Double H Valve is to supply air to the high and low gear switching cylinder.
2. If it is damaged, it will appear that the high and low gears cannot be converted.
3. If there is air leakage from the double H shift valve, whether it is high or low gear shifting cylinder air leakage will cause high-grade and no low-grade, or low-grade and no high-grade faults. The method of checking for air leakage is simple: if the gear shift The box has low gear but no high gear. Push the shift lever from the low gear area to the high gear area, and then disassemble the low gear shift cylinder intake connector. If there is air leakage from the cylinder connector 1 at this time, it means that the gear shift cylinder is leaking. . If the air is still exhausted from the exhaust port of the double H shift valve at this time, it means that the double H shift valve is leaking. In the same way, if the transmission has high gear but no low gear, push the shift lever into the low gear area, and disassemble the intake joint of the high gear working cylinder, if there is continuous air leakage from this joint. It means that the shift cylinder is leaking air. If there is still exhaust from the double H shift valve at this time, it means that the double H shift valve is leaking. Generally speaking, the failure of the double H shift valve, if there is no replaceable sealing ring, only the entire valve can be replaced.
