3.5. Lubrication system The engine is equipped with force-feed lubrication. The pressure is produced by a gear pump whose drive gear is in direct mesh with the crankshaft gear at the front end of cylinder block. The oil pump draws the oil from the oil sump and delivers it through the oil cooler and oil filter to the main distributor gallery and from there to the main bearings, big-end bearings and camshaft bearings as well as to the small-end bearings and the rocker arms. The injection pump and the turbocharger are also connected to the engine lubricating system. The cylinder walls and timing gears are splash-lubricated.
Each cylinder has an oil jet provided for cooling the underside of the pistons. The lube oil is cleaned in a full-flow oil filter.

Recommend of lubricating oil Initial factory fill is high quality break-in oil for API Service CD.
During the break-in period (50 hours), frequently check the oil level. Somewhat higher oil consumption is normal until piston rings are seated. The oil level should be maintained in the safe range between the Min. and Max. marks on the dipstick. The safe range between the marks represents approximately 3 liters. To obtain the best engine performance and engine life, grade of engine oil is recommended. Engine oils are specified by API Service, letter designations and SAE viscosity numbers. If the specified motor oil is not available, use a reputable brand of engine oil labeled for API Service CD and SAE viscosity 30 or 15w40. Refer to oil identification symbol on the container.
Engine oil should be changed at the specified intervals. (800hr) - 13 -
