Engine Lubrication System - Suzuki DF 90 Service Manual

ENGINE LUBRICATION SYSTEM

A camshaft driven trochoid type pump provides engine oil to all power unit components requiring lubrication.
Oil from the oil pan is drawn through the oil strainer and passed through a spin-on type oil filter before
entering the main oil gallery.
A pressure regulator (relief valve) is positioned between the oil pump and oil filter to maintain oil pressure at
a constant level.
From the main gallery, oil flow is directed through either drilled internal passages or by splash method to
those surfaces requiring lubrication.
