ZF 4108.311.070 WHEEL | OEM Genuine Part

Overview

The ZF 4108.311.070 WHEEL is a critical OEM genuine component engineered for the final drive assembly within ZF construction machinery transmissions. This precision-machined wheel functions as a load-bearing interface, transmitting rotational torque from the planetary gear set to the axle shaft. As an integral part of the drivetrain, it ensures smooth power delivery under extreme loads. The SKU 4108.311.070 is specifically designed to maintain exacting tolerances, reducing vibration and wear in heavy-duty applications. When installed alongside the 4108101068 HOUSING and 4108201177 HOUSING, this wheel forms a sealed, durable assembly that withstands high-stress environments in excavators and loaders.

Symptoms of Failure

• Transmission gear slipping under load: A worn 4108.311.070 wheel can cause intermittent power loss, especially when climbing grades or lifting heavy materials, as the wheel no longer engages properly with mating gears.
• Metallic grinding noise from the final drive: When the wheel’s splines or bearing surfaces degrade, operators will hear a distinct grinding or whining sound during acceleration or deceleration, indicating imminent failure.
• Oil leaks near the wheel hub: Cracks or deformation in the wheel can compromise the seal interface, leading to visible hydraulic or gear oil seepage around the axle housing.
• Increased drivetrain vibration: A warped or unbalanced wheel creates harmonic vibrations that worsen at higher RPMs, often felt through the chassis and steering controls.

Technical Specifications

Compatibility

This wheel is primarily used in ZF WG180, WG200, and WG210 series transmissions found in mid-to-large construction machinery. It is also compatible with select ZF 4WG-200 and 5WG-200 variants. For proper installation, always pair this part with the 0636302056 SCREW PLUG to secure the lubrication circuit, and the 4108301304 BEARING COVER to protect the wheel from debris ingress. Verify your transmission model’s serial number before ordering to ensure exact fitment.
