What is charge pressure on a travel motor?
Expert Answer
Charge pressure is the low, continuous pressure in a closed-loop hydraulic drive circuit that keeps a travel motor supplied with oil. It helps make up for internal leakage, keeps the loop full, and often provides the pressure needed to release the spring-applied park brake in the drive motor. If charge pressure is too low, a machine may travel weakly, freewheel, or fail to disengage the brake properly. If you are diagnosing a travel motor issue, charge pressure is one of the first things to check along with filters, charge pump output, and case drain flow.
