Question

Two technicians are discussing the viscous coupling used in all-wheel drive systems. Technician A says a viscous fluid such as a silicon-based oil is added to the assembly and fills the areas between the clutch plates. Technician B says the viscous coupling is active during equal traction conditions. Which technician is correct?

Answer 1

Technician A is correct

Step-by-step explanation:

In this discussion , technician A is correct.

Viscous fluid is a silicon based fluid. It is present in the clutch area and the coupling. Viscous fluid is added to the clutch assembly and it readily fills the area between the clutch pales.

Thus in this conversation, technician A is correct.

Technician B is wrong because the viscous coupling does not remain active when there is equal traction conditions between the wheels.

Hence the answer is --- Technician A is correct
