Tellerrad / With Pinion I=4.778 43/9
The Tellerrad with Pinion I = 4.778 (43/9) transfers engine torque to the axle, enabling smooth and efficient differential operation.
This gear set includes a precision-machined crown wheel (Tellerrad) and pinion designed to work together with a final drive ratio of 4.778. The 43/9 tooth combination ensures optimal torque multiplication, load distribution, and power delivery to the wheels. Made from high-strength alloy steel, the gears withstand extreme loads, shock forces, and continuous operation in heavy-duty commercial vehicles.
By maintaining accurate meshing and minimal friction, the gear set enhances vehicle pulling power, ensures quiet differential performance, and improves drivetrain efficiency. It also contributes to long-term reliability, reduced wear, and smoother power transmission under demanding conditions.

FAQ
What does the Tellerrad and pinion do?
They work together to transfer torque from the driveshaft to the axle with a specific final drive ratio.
When should the gear set be replaced?
When noise, vibration, metal particles in oil, or poor differential performance is observed.
