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.
Intermediate Shaft
| Number | Designation | Number | Designation |
| 1 | Camshaft transmission sprocket | 5 | Intermediate wheel |
| 2 | Drive wheel for the auxiliary unit | 6 | Crankshaft sprocket |
| 3 | Intermediate shaft | 7 | Oil pump |
| 4 | Freewheel clutch |
The intermediate shaft is located in the gear housing on the cylinder block. The intermediate shaft drives the camshafts and the auxiliary unit.
There is a sprocket on the rear section of the crankshaft, which drives the intermediate shaft via an intermediate wheel. The intermediate wheel drives the intermediate shaft via the intermediate shaft's centrally mounted gear. The intermediate shaft has a further two gear wheels of different sizes.
The intermediate shaft's front gear wheel has a freewheel clutch that drives the alternator at 2.7 times the engine speed. A free wheel clutch drives in one direction and slips/freewheels in the other direction.
The rear gear wheel drives the overhead camshafts.
