Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Lubrication System
| Number | Designation | Number | Designation |
| 1 | Oil pan | 5 | Oil dipstick |
| 2 | Oil pump | 6 | Housing for the oil filter |
| 3 | Oil pressure line | 7 | Supply to the vibration damper's cooling nozzle. |
| 4 | Oil cooler | 8 | Oil suction line |
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 to the oil cooler 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.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
