Common Faults and Causes

Caterpillar SBS120 hydraulic pump will meet bellows common problems.

1. Performance decline, slow action: the machine responds slower and the working cycle is prolonged. Most of them are caused by internal leakage due to the wear of the internal distribution disc of the pump, the increase in the secondary gap of the plunger or the delay in response of the variable mechanism.
2. Difficulty in dropping the arm and lifting: the big arm is slow to lift, weak in the middle and even "can't straighten the car". This is a typical symptom of SBS120 pump performance decline.
3. Insufficient power (obvious after the heating machine): the system pressure does not meet the requirements when carrying, and it is aggravated after the heating machine.
4. Abnormal noise (abnormal noise, knocking): The pump body makes a whistling, knocking or grinding sound, which usually indicates that the rotating element is seriously worn or caviting.
5. External oil leakage: oil leakage at the pump body or oil port
