Lubrication System
5919 690 01 Rev. -- KohlerEngines.com
This engine uses a full pressure lubrication system which delivers oil under pressure to crankshaft, camshaft, and
connecting rod bearing surfaces.
A high-effi ciency gerotor oil pump maintains high oil fl ow and oil pressure, even at low speeds and high operating
temperatures. A pressure relief valve limits maximum pressure of system. Oil pan must be removed to service oil
governor gear and oil pump.
