Engine Oiling System
Slipper gear type pump is used. Oil pump is mounted at front of engine and driven by crankshaft. See Fig 1. An oil suction tube, extending from oil pump, lifts oil from oil pan. Oil is then fed to internal engine moving parts. Lubrication is either by pressure feed or drainage method.
To aid in piston cooling, turbo engines use oil nozzles which are installed at bottom of each cylinder. Oil is sprayed into underside of piston to cool piston skirt and head. If oil nozzles are removed, coat retaining bolt threads with thread adhesive on installation.
