In the process of using the crawler transporter, if there is improper manipulation, frequent increase of throttle, long-term overload operation, long braking conditions, unlike the high transmission oil temperature of the earthmover, the high transmission oil temperature of the crawler truck may occur in many ways, and the overhaul should strictly follow the guidelines of first outside and then inside, first simple and then messy together.

The type, oil level and cleanliness of the torque converter operating fluid, whether it is replaced regularly, caused by high water temperature of the engine of the crawler transport truck (when starting, the engine water temperature rises faster than the torque converter oil temperature) or sea raising, low gas pressure, blockage of the torque oil radiator, reduction of heat dissipation area (the torque converter oil temperature is significantly higher than the engine water temperature), and lack of belt loosening electric fan exhaust.

Water tank water level is low crawler truck engine oil cold cutter pipeline rupture, view abnormal words, may be related to the damage of the torque converter element or two shaft assembly, view the four unlike pulling earth truck transmission oil sump, there are aluminum chips, copper chips iron chips: aluminum chips, torque converter axial positioning damage, four elements interference wear, copper chips, at a pressure < 0.68MPa, copper-based friction plate between the slip grinding, iron chips or roller debris, the Overrun clutch damage bearing damage gear damage, torque converter rotating oil seal damage (start motor leakage), lack of oil supply to the system (a certain element on the oil road occurs saving phenomenon), present cavitation phenomenon (whether the water filter is replaced regularly).
