The main function of the timing belt is to drive the valve train of the engine, enabling the intake and exhaust valves of the engine to be opened or closed at appropriate times, to ensure that the cylinders of the fully automatic concrete mixer truck engine can normally inhale and exhaust.
In some models, the timing belt is also responsible for driving the water pump. The belt of the mixer truck is a rubber component. As the engine working time increases, the timing belt and its accessories, such as the timing belt tensioner, timing belt tensioner, and water pump, will be worn or aged.
Therefore, for engines equipped with timing belts, the manufacturer will have strict requirements to regularly replace the timing belt and accessories within the specified cycle. The replacement cycle varies depending on the structure of the engine. Generally, when the mixer truck reaches 60000 to 100000 kilometers, it should be replaced. The specific replacement cycle should be subject to the instructions in the maintenance manual of the mixer truck.
In addition, its daily maintenance should also be done well, such as:
Before each vehicle departure, the hydraulic oil level should be checked, and it is advisable to increase the oil level by 2-3 cm;
Places with grease fittings should be greased once a week to ensure normal lubrication. In addition, the junction surface between the tugboat and the raceway should be buttered once every 3-4 days to keep it normal;
Each time the rear control handle changes from mixing to unloading or from unloading to mixing, it should pause in the middle position, and then perform the next action after the mixing drum stops rotating. Do not continue to exert force when the handle is pulled to the limit position to prevent the oil pump from getting stuck;
At the end of each job, clean the inside and outside of the mixing drum to ensure that there is no accumulation of fast inside the mixing drum. If the unloading time at the construction site exceeds 2-3 hours, the mixing drum should also be cleaned when returning. For more relevant content, please visit our website Consult and understand!
