CARRIER ROLLER/TOP ROLLER/UPPER ROLLER

The carrier roller leaks oil. Don't rush to replace it. It can be repaired!
The four-wheel area is very familiar to the old drivers who deal with excavators every day. Generally, the four-wheel area belongs to vulnerable parts. If it is broken or worn, you can directly find the boss to replace it.

It's easy to replace it. What I fear most is that there is oil leakage in the tugboat. Oil leakage means that the fault point must be found. The troubleshooting process is not simple. Sometimes it even costs a lot of money to ask the master for disassembly and inspection.

Fault phenomenon:

The phenomenon is obvious and simple. The operator found that the supporting sprocket had oil leakage (oil leakage) and directly fed it back to the owner.

Fault analysis:

when driving for a long time and a long distance, the tugboat will leak oil, which needs careful observation and confirmation

Shaft wear, which will certainly cause the problem of oil leaking.

The oil seal of top roller is aging also will cause oil leaking

Troubleshooting

1. Remove the supporting wheel from the X frame support, open the outer end cover, and separate the rotating wheel body from the inner stator;

2. Remove the floating oil seal, clean the corresponding position of the wheel body and stator with the floating oil seal, and note that there shall be no oil stain;

3. Install a new floating oil seal, add grease, reassemble the wheel body and stator, and install the end cover;

4. Install the repaired carrier roller back to the frame and idle for about 5 minutes to ensure that there is no oil leakage.
