We've been working on this bulldozer for 3 months, but it's been better for a while, but these days the left pull rod is only turning around in the cooling state. Work for a long time on the sudden death, the rod.... safety valve is not changed to / / / please master pointing out. The bulldozer is urgently wait for the public.. Thank you
After these failures occur, the classification and analysis of the use time of the bulldozer and the course of the failure will be carried out, and the inspection can be carried out in real cases to avoid unnecessary disassembly and to reduce the pollution inside the machine.
Bulldozer in the use of the process, due to various reasons caused by the difficulties, can not turn, turn the bulldozer cold car can turn hot cannot turn (part transmission oil temperature rise to operating temperature after the fault phenomenon).
The following are the common failures of bulldozers and the inspection and elimination of them. When the bulldozer is in use, the two sides can not turn the fault suddenly, and the relief valve at the inlet of the steering control valve assembly can be disassembled. The reason is too dirty, the inner surface of oil in the oil impurities or drag the overflow valve and the valve body rubs, the spool stuck in the open position on the oil return, lost the adjustment function of the hydraulic system, the pressure is not up to the standard value.
The relief valve after the disintegration of inspection parts such as damage is particularly serious, available No. 180 or no. 240 on the damaged parts of emery cloth, grinding. If the parts are badly damaged, replace them. At the same time, the oil and fine filter must be replaced and the coarse filter core must be cleaned.
