The forklift drive axle of the electric forklift manufacturer is noisy: the lubricating oil is insufficient, and the lubricating oil needs to be added according to the specified requirements; The gears, bearings and other parts are excessively worn or damaged, which need to be checked, repaired or replaced. Improper adjustment, excessive gear meshing clearance or improper bearing pretension requires readjustment and inspection. The cross shaft of the differential is loose and needs to be replaced.

The forklift oil circuit system of the electric forklift manufacturer cannot establish pressure: the oil circuit is not sealed in the high and low cavities, and the internal leakage is serious. It is necessary to check the pipeline dirt and replace the seal; the outlet back pressure valve does not generate back pressure, check, repair and replace; the oil pump is damaged Need to be replaced.

Electric forklift manufacturer forklift torque converter oil temperature is high: the guide wheel is stuck or the rotation is not flexible and needs to be checked, repaired and replaced; The working oil does not meet the requirements and needs to be replaced with new oil. The oil level is too low or the system generates bubbles, increasing the working oil to remove bubbles; The oil pipe cooler in the system is blocked and dirt in the system is needed. Bearing and gear damage need to be replaced. Serious internal leakage, check and replace seals.

The gear position of the forklift gearbox of the electric forklift manufacturer cannot be disengaged: the friction plate is burned and needs to be replaced; the return spring is damaged and needs to be replaced; the oil return circuit is blocked and foreign matter needs to be removed; the micro-valve brake interlock valve does not return and the spring needs to be replaced.

Electric forklift manufacturers forklift gearbox noise: gear or bearing wear needs to be replaced; Insufficient bearing preload needs to be readjusted.
