Maintenance of excavator includes: engine, hydraulic pressure, traveling reducer, crawler, three-filter, etc., but many car owners have ignored the maintenance of the excavator through the idler, roller and drag pulley. Today, Xiaobian will introduce the knowledge about "Hitachi 70-5G excavator idler, roller and drag pulley maintenance"China Excavator Idler
We don't care much about these things in our daily work. They are replaced when they are broken. They are disposable. They are never filled with oil in the middle of the way. Especially, the maintenance of vehicles that often work in the mud is lacking. This will lead to the damage of the bearing of the supporting wheel, the drag wheel, and the idler wheel, resulting in the dry grinding of the shaft. It is only necessary to replace them, which costs money. Now let's show you how to maintain the chassis wheels of Hitachi 70-5G excavator

When the screw is unscrewed, the needle can be pumped directly into the tank after it is full of oil. It takes about 50ml. Take it slowly and don't rush, otherwise the oil will come out, and it will take time for it to exhaust. When you want to add oil, screw the tractor oil pressure gauge pipe directly on the engine and pump it in directly. When you see that the oil pipe can't be screwed on

The drag chain wheel is also removed and fastened
The idler wheel is directly removed from the screw, and the grease is inserted into it. The engine car is supported while idling while filling oil

I don't have to worry about it. If I do it once a year, the durability of the wheel will be much better. It can save a lot of maintenance costs, but it is a little laborious. If the conditions are good, you can use the air gun to remove it. If you go straight up and down, you can add more fuel. My conditions are simple, and I can only add fuel when the car is straight up about 30 degrees
Well, I would like to share with you the maintenance of the guide wheel, supporting wheel and drag chain wheel of Hitachi 70-5G excavator. I hope it can help the owners!China Excavator Idler
