1, the engine oil storage capacity is too small, resulting in lubrication system without oil or less oil, resulting in low oil pressure. Solution: make up the oil.

2, dirty oil or viscous oil pump can not be effective inhalation, pump, resulting in low or no pressure oil pressure. Solution: oil change.

3, the oil is thin or because the engine temperature caused by oil thinning, from the engine of the friction in the gap between the leakage, resulting in low oil pressure. Solution: oil change or maintenance cooling system.

4, North Ben v3 accessories oil tubing oil spills, oil pump damage or excessive wear and tear of its parts will lead to oil inhalation, pumping volume reduction, or simply immeasurable, resulting in low oil pressure or no pressure. Solution: overhaul.

5, North Ben v3 accessories crankshaft and the gap between the size of the gap caused by oil leakage, resulting in low oil pressure. Solution: overhaul.

6, pressure limiting valve or relief valve spring is too soft or card or steel ball damage caused by the function of the valve disappeared or weakened lead to lower oil pressure. Workaround: Replace the service.

7, North Ben v3 accessories oil sensor plug, pressure gauge or circuit failure caused by low oil pressure. Workaround: Replace the check.
