| 3 | Oil pressure line | 7 | Oil suction line |
| 4 | Oil cooler |
The task of the lubrication system is to build-up a protective film of oil between the moving parts of the engine. The lubrication system must also transport dirt particles away from the moving parts and cool hot engine parts.
This is carried out by the oil pump supplying oil to the oil filter through an oil pressure line of treated steel.
Clean oil is supplied from the oil filter to the oil cooler. From there the oil is further distributed, through a duct system, out to the various engine functions.
A pressure sensitive valve controls the oil flow to the vibration damper's oil cooler pipe if necessary.
Oil pump
The oil pump is in the oil pan, mounted underneath the intermediate section. The oil pump has an integrated relief valve. The pump is directly driven by the sprocket on the rear end of the crankshaft.
The oil pump draws oil from a centrally located nozzle in the sump.
The pump increases the pressure of the oil for lubrication, cooling and hydraulic functions.
Oil filter module
The oil filter module consists of an oil filter reservoir and an oil cooler. It is mounted on the intermediate section. The oil filter module is element based and can be taken apart.
The oil cooler is connected to the coolant system. Coolant is led through the oil cooler.
