How do I know if a second-hand excavator has undergone major repairs?

According to a survey on the homepage of Shanghai Huacheng Second hand Excavator www.shcteng.com, the three most important points for users who buy second-hand excavators are:Second hand excavator pricesThe overall performance of the vehicle and whether there are records of major repairs. So how can I tell if a second-hand excavator has undergone major repairs?

1、 By observing whether there are any repair marks on the engine and hydraulic pump

The major overhaul of an excavator is nothing more than cleaning or painting the engine and hydraulic pump. If they are cleaned or painted after the overhaul, the bolts that must be removed during the overhaul must be removed to see if there are any gaps in the bolt pattern and if the bolts and bolts inside are clean. After installing a new excavator, the bolts are painted tightly and the gaps are blocked, making it impossible for stolen goods to enter. If the surface or pattern of the bolts is damaged or dirty, it proves that they have been dismantled. Since the major overhaul has been carried out, there must be traces, such as whether the back of the cab is severely damaged, or whether there are many worn bolts in the engine hydraulic pump and the part where the engine hydraulic pump is installed, which are easy to see.

2、 View the hourly schedule of the excavator

A typical excavator will face major repairs after working for 10000 hours.

You can check the hour meter on the excavator. If the working hours are over 20000, this excavator is usually overhauled.

However, many second-hand excavators have already adjusted their hour meters, and the working hours on the meters are no longer reliable.

It is not difficult to see from the above two points that there is a high possibility that second-hand excavators of models such as -2, -3, and -5 have undergone major repairs. Of course, it cannot be ruled out that the machine is well maintained.

When purchasing a second-hand excavator, it is often not enough to only focus on whether it has undergone major repairs. Use more and more reliable methodsMethod for purchasing second-hand excavatorsIt is a wiser choice.
