4566 690 07 Rev. -- KohlerEngines.com
This engine uses a full pressure lubrication system. This system delivers oil under pressure to crankshaft, camshaft
and connecting rod bearing surfaces. In addition to lubricating bearing surfaces, lubrication system supplies oil to
hydraulic valve lifters.
A high-effi ciency gerotor pump is located in closure plate. Oil pump maintains high oil fl ow and oil pressure, even
at low speeds and high operating temperatures. A pressure relief valve in closure plate limits maximum pressure of
system.
