− Incorrectly wired motor
− Binding internal pump parts
− Motor normally feel hot
− Reduce downstream pressure. Check relief
valve setting. Be sure discharge pressure
gages function correctly.
− Reduce speed
− Change to larger horsepower or higher
service factor motor. Thin fluid.
− Check wiring diagram
− Inspect and correct condition
− Verify if actual motor amperage draw is within
range.
6. Seal leaks − Dry running
