What is the problem with the idler wheel of the excavator?

1, the main clutch slips


When the main clutch of the excavator slips, the engine speed is normal and does not emit black smoke, and the working device works normally, but the machine is difficult to climb and cannot even walk. The main clutch slip is the most common failure of the excavator. The main reasons are: wear of the main and driven plates; the lock pin of the adjustment disk is welded; the control lever of the main clutch is not in place; Clutch slipping problems are sometimes very difficult to handle. Generally, the repairman's method is to repeatedly rotate the adjustment disk. If the clutch still slips after adjusting the adjustment disk for many times, it is often to remove the transmission first and dismantle the main clutch blindly. This will not only find the failure point but also damage other parts and delay production, resulting in large economic losses. For this reason, careful analysis should be carried out according to the possible causes mentioned above in order to be effective.


2, the main clutch lever is heavy


The main reasons are: the oil filter is clogged and the oil supply is insufficient, making the booster ineffective; the main clutch hydraulic system is short of oil; the booster is damaged or the booster safety valve is defective; the bimetallic sleeve in the moving sleeve is burned. When there is a serious failure of the clutch lever, you should first check whether the oil level of its hydraulic system meets the requirements; if the oil level is appropriate, you can temporarily remove the oil filter and then pull the main clutch lever. If you feel that the lever is stiff, It means that the oil filter is blocked. In this case, you only need to clean or replace the oil filter. If the oil circuit is normal, but the main clutch lever is heavy, you can first check whether the safety valve of the booster is stuck or draining oil. If there is no problem with the booster safety valve, you must check the booster; or check the bimetal sleeve in the moving sleeve Whether it is burnt or not, it can be replaced with a new one.
