High Efficiency Crawler Bulldozer

shift control valve is faulty bulldozer hydraulic system is quite delicate, especially the various hydraulic control valves, valve gear is one of them. Poor cleanliness of hydraulic oil or using improper maintenance,High Efficiency Crawler Bulldozer  will result in the shift valve malfunction, so inadequate fuel supply converter. Especially 160 bulldozer, variable speed torque converter only way hydraulic oil systems, there is a huge shift valve failure impact on the system. In general, the safety valve stuck in the valve gear is the most direct and common form of failure. You can check the shift valve, power shift hydraulic bulldozers the oil inlet pressure (pressure relief valve inlet pressure that speed for 2.5MPa; pressure relief valve outlet pressure converter that between 0.5-0.9MPa), shift valve fails mainly the system pressure is low; the shift valve safety valve should be removed and cleaned, to troubleshoot.
